AWS Certified Solutions Architect - Professional Questions and Answers

Question 1

Question:

A company runs an application on Amazon EC2 and AWS Lambda. The application stores temporary data in Amazon S3. The S3 objects are deleted after 24 hours.

The company deploys new versions of the application by launching AWS CloudFormation stacks. The stacks create the required resources. After validating a new version, the company deletes the old stack. The deletion of an old development stack recently failed.

A solutions architect needs to resolve this issue without major architecture changes.

Which solution will meet these requirements?

Options:

Create a Lambda function to delete objects from the S3 bucket. Add the Lambda function as a custom resource in the CloudFormation stack with a DependsOn attribute that points to the S3 bucket resource.

Modify the CloudFormation stack to attach a DeletionPolicy attribute with a value of Delete to the S3 bucket.

Update the CloudFormation stack to add a DeletionPolicy attribute with a value of Snapshot for the S3 bucket resource.

Update the CloudFormation template to create an Amazon EFS file system to store temporary files instead of Amazon S3. Configure the Lambda functions to run in the same VPC as the EFS file system.

Question 2

A company creates an Amazon API Gateway API and shares the API with an external development team. The API uses AWS Lambda functions and is deployed to a stage that is named Production.

The external development team is the sole consumer of the API. The API experiences sudden increases of usage at specific times, leading to concerns about increased costs. The company needs to limit cost and usage without reworking the Lambda functions.

Which solution will meet these requirements MOST cost-effectivery?

Options:

Configure the API to send requests to Amazon SQS queues instead of directly to the Lambda functions. Update the Lambda functions to consume messages from the queues and to process the requests. Set up the queues to invoke the Lambda functions when new messages arrive.

Configure provisioned concurrency for each Lambda function. Use AWS Application Auto Scaling to register the Lambda functions as targets. Set up scaling schedules to increase and decrease capacity to match changes in API usage.

Create an API Gateway API key and an AWS WAF Regional web ACL. Associate the web ACL with the Production stage. Add a rate-based rule to the web ACL. In the rule, specify the rate limit and a custom request aggregation that uses the X-API-Key header. Share the API key with the external development team.

Create an API Gateway API key and usage plan. Define throttling limits and quotas in the usage plan. Associate the usage plan with the Production stage and the API key. Share the API key with the external development team.

Question 3

A solutions architect is investigating an issue in which a company cannot establish new sessions in Amazon Workspaces. An initial analysis indicates that the issue involves user profiles. The AmazonWorkspaces environment is configured to use Amazon FSx for Windows File Server as the profile share storage. The FSx for Windows File Server file system is configured with 10 TB of storage.

The solutions architect discovers that the file system has reached its maximum capacity. The solutions architect must ensure that users can regain access. The solution also must prevent the problem from occurring again.

Which solution will meet these requirements?

Options:

Remove old user profiles to create space. Migrate the user profiles to an Amazon FSx for Lustre file system.

Increase capacity by using the update-file-system command. Implement an Amazon CloudWatch metric that monitors free space. Use Amazon EventBridge to invoke an AWS Lambda function to increase capacity as required.

Monitor the file system by using the FreeStorageCapacity metric in Amazon CloudWatch. Use AWS Step Functions to increase the capacity as required.

Remove old user profiles to create space. Create an additional FSx for Windows File Server file system. Update the user profile redirection for 50% of the users to use the new file system.

Question 4

A company is planning to host a web application on AWS and works to load balance the traffic across a group of Amazon EC2 instances. One of the security requirements is to enable end-to-end encryption in transit between the client and the web server.

Which solution will meet this requirement?

Options:

Place the EC2 instances behind an Application Load Balancer (ALB) Provision an SSL certificate using AWS Certificate Manager (ACM), and associate the SSL certificate with the ALB. Export the SSL certificate and install it on each EC2 instance. Configure the ALB to listen on port443 and to forward traffic to port 443 on the instances.

Associate the EC2 instances with a target group. Provision an SSL certificate using AWS Certificate Manager (ACM). Create an Amazon CloudFront distribution and configure It to use the SSL certificate. Set CloudFront to use the target group as the origin server

Provision a third-party SSL certificate and install it on each EC2 instance. Configure the ALB to listen on port 443 and to forward traffic to port 443 on the instances.

Place the EC2 instances behind a Network Load Balancer (NLB). Provision a third-party SSL certificate and install it on the NLB and on each EC2 instance. Configure the NLB to listen on port 443 and to forward traffic to port 443 on the instances.

Question 5

A company has an organization that has many AWS accounts in AWS Organizations. A solutions architect must improve how the company manages common security group rules for the AWS accounts in the organization.

The company has a common set of IP CIDR ranges in an allow list in each AWS account to allow access to and from the company's on-premises network.

Developers within each account are responsible for adding new IP CIDR ranges to their security groups. The security team has its own AWS account. Currently, the security team notifies the owners of the other AWS accounts when changes are made to the allow list.

The solutions architect must design a solution that distributes the common set of CIDR ranges across all accounts.

Which solution meets these requirements with the LEAST amount of operational overhead?

Options:

Set up an Amazon Simple Notification Service (Amazon SNS) topic in the security team's AWS account. Deploy an AWS Lambda function in each AWS account. Configure the Lambda function to run every time an SNS topic receives a message. Configure the Lambda function to take an IP address as input and add it to a list of security groups in the account. Instruct the security team to distribute changes by publishing messages to its SNS topic.

Create new customer-managed prefix lists in each AWS account within the organization. Populate the prefix lists in each account with all internal CIDR ranges. Notify the owner of each AWS account to allow the new customer-managed prefix list IDs in their accounts in their security groups. Instruct the security team to share updates with each AWS account owner.

Create a new customer-managed prefix list in the security team's AWS account. Populate the customer-managed prefix list with all internal CIDR ranges.

Create an IAM role in each account in the organization. Grant permissions to update security groups. Deploy an AWS Lambda function in the security team's AWS account. Configure the Lambda function to take a list of internal IP addresses as input, assume a role in each organization account, and add the list of IP addresses to the security groups in each account.

Question 6

A company has an application that stores user-uploaded videos in an Amazon S3 bucket that uses S3 Standard storage. Users access the videos frequently in the first 180 days after the videos are uploaded. Access after 180 days is rare. Named users and anonymous users access the videos. Most of the videos are more than 100 MB in size. Users often have poor internet connectivity when they upload videos, resulting in failed uploads. The company uses multipart uploads for the videos. A solutions architect needs to optimize the S3 costs of the application. Which combination of actions will meet these requirements? (Select TWO.)

Options:

Configure the S3 bucket to be a Requester Pays bucket.

Use S3 Transfer Acceleration to upload the videos to the S3 bucket.

Create an S3 Lifecycle configuration to expire incomplete multipart uploads 7 days after initiation.

Create an S3 Lifecycle configuration to transition objects to S3 Glacier Instant Retrieval after 1 day.

Create an S3 Lifecycle configuration to transition objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 180 days.

Question 7

A company runs an loT application in the AWS Cloud. The company has millions of sensors that collect data from houses in the United States. The sensors use the MOTT protocol to connect and send data to a custom MQTT broker. The MQTT broker stores the data on a single Amazon EC2 instance. The sensors connect to the broker through the domain named iot.example.com. The company uses Amazon Route 53 as its DNS service. The company stores the data in Amazon DynamoDB.

On several occasions, the amount of data has overloaded the MOTT broker and has resulted in lost sensor data. The company must improve the reliability of the solution.

Which solution will meet these requirements?

Options:

Create an Application Load Balancer (ALB) and an Auto Scaling group for the MOTT broker. Use the Auto Scaling group as the target for the ALB. Update the DNS record in Route 53 to an alias record. Point the alias record to the ALB. Use the MQTT broker to store the data.

Set up AWS loT Core to receive the sensor data. Create and configure a custom domain to connect to AWS loT Core. Update the DNS record in Route 53 to point to the AWS loT Core Data-ATS endpoint. Configure an AWS loT rule to store the data.

Create a Network Load Balancer (NLB). Set the MQTT broker as the target. Create an AWS Global Accelerator accelerator. Set the NLB as the endpoint for the accelerator. Update the DNS record in Route 53 to a multivalue answer record. Set the Global Accelerator IP addresses as values. Use the MQTT broker to store the data.

Set up AWS loT Greengrass to receive the sensor data. Update the DNS record in Route 53 to point to the AWS loT Greengrass endpoint. Configure an AWS loT rule to invoke an AWS Lambda function to store the data.

Question 8

A company hosts a payment processing platform across multiple AWS Regions. The processing platform exposes payment processing API endpoints. The company uses Amazon Route 53 to route traffic to an Application Load Balancer (ALB) in each Region to distribute requests to backend payment gateways. The company has implemented Auto Scaling for the payment gateways.

The company needs to improve reliability and availability by handling application failures quickly.

Which solution will meet this requirement with the LEAST response time for global users?

Options:

Configure Route 53 to use a geolocation routing policy to resolve DNS to an Amazon CloudFront distribution. Configure the distribution with an origin group that includes the ALBs from each Region as origins.

Create an accelerator in AWS Global Accelerator. Create an endpoint group and add each ALB as an endpoint in the group. Update the Route 53 alias records to point to the accelerator.

Configure Route 53 to use a latency-based routing policy and health checks for each Regional endpoint.

Set up cross-Region connectivity by using AWS Cloud WAN to connect VPCs across Regions. Use network policies to route traffic from each Region to the Region that is closest to the origin Region.

Answer:

Explanation:

Comprehensive and Detailed Explanation From Exact Extract:

Answer B (AWS Global Accelerator) best meets both requirements: fastest failover from application failures and the lowest response time for global users. Global Accelerator is designed for global, latency-sensitive, highly available applications. It uses static Anycast IP addresses so users enter the AWS network at the nearest edge location, then traffic is carried over the AWS global backbone to the closest healthy regional endpoint (in this case, each Region’s ALB). It continuously performs health checks and can rapidly shift traffic away from unhealthy endpoints, which helps “handle application failures quickly” without being constrained by DNS caching behavior.

Why the other options are less suitable:

C (Route 53 latency-based routing + health checks) can improve routing and failover, but it is still DNS-based. DNS-based failover can be delayed by DNS resolver caching and TTL propagation, meaning failover may not be as fast or as consistent as Global Accelerator for rapid recovery.

A (CloudFront with origin group) can provide origin failover and performance benefits mainly for cacheable or edge-optimizable content. For a payment processing API (typically dynamic and not cache-friendly), CloudFront is not the primary service for achieving the least response time globally with fast multi-Region failover compared with Global Accelerator’s Anycast + edge routing model.

D (AWS Cloud WAN) addresses private network connectivity and centralized network policy across Regions/VPCs. It does not directly optimize public user-to-application latency or provide the same kind of edge-based, Anycast-driven rapid failover for internet-facing API endpoints.

[References:, AWS Global Accelerator Documentation (concepts: static Anycast IPs, endpoint groups, health checks, traffic routing and failover), Amazon Route 53 Documentation (concepts: latency-based routing, health checks, DNS caching/TTL effects on failover), AWS Certified Solutions Architect – Professional (SAP-C02) Exam Guide (domains covering global networking service selection, multi-Region availability, and resilience design), , , ]

Question 9

A company hosts a metadata API on Amazon EC2 instances behind an internet-facing Application Load Balancer (ALB). Only internal applications that run on EC2 instances in separate AWS accounts need to access the metadata API. All the internal EC2 instances use NAT gateways.

A new policy requires that traffic between internal applications must not travel across the public internet.

Which solution will meet this requirement?

Options:

Create an HTTP API in Amazon API Gateway. Configure a route for the metadata API. Configure a VPC link to the VPC that hosts the metadata API's EC2 instances. Update the API Gateway resource policy to include the account IDs of the internal applications that access the metadata API.

Create a REST API in Amazon API Gateway. Specify the API Gateway endpoint type as private. Associate the REST API with the metadata API's VPC. Create a gateway VPC endpoint for the REST API. Share the endpoint across accounts by using AWS Resource Access Manager (AWS RAM). Configure the internal applications to connect to the gateway VPC endpoint.

Create an internal ALB. Register the metadata API's EC2 instances with the internal ALB. Create an internal Network Load Balancer (NLB) that has a target group type of ALB. Register the internal ALB as the target. Configure an AWS PrivateLink endpoint service for the NLB. Grant the internal applications access to the metadata API through the PrivateLink endpoint.

Create an internal ALB. Register the metadata API's EC2 instances with the internal ALB. Configure an AWS PrivateLink endpoint service for the internal ALB. Grant the internal applications access to the metadata API through the PrivateLink endpoint.

Question 10

A company is using GitHub Actions to run a CI/CD pipeline that accesses resources on AWS. The company has an IAM user that uses a secret key in the pipeline to authenticate to AWS. An existing IAM role with an attached policy grants the required permissions to deploy resources.

The company's security team implements a new requirement that pipelines can no longer use long-lived secret keys. A solutions architect must replace the secret key with a short-lived solution.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Create an IAM SAML 2.0 identity provider (IdP) in IAM. Create a new IAM role with the appropriate trust policy that allows the sts:AssumeRole API call. Attach the existing IAM policy to the new IAM role. Update GitHub to use SAML authentication for the pipeline.

Create an IAM OpenID Connect (OIDC) identity provider (IdP) in IAM. Create a new IAM role with the appropriate trust policy that allows the sts:AssumeRoleWithWebIdentity API call from the GitHub OIDC IdP. Update GitHub to assume the role for the pipeline.

Create an Amazon Cognito identity pool. Configure the authentication provider to use GitHub. Create a new IAM role with the appropriate trust policy that allows the sts:AssumeRoleWithWebIdentity API call from the GitHub authentication provider. Configure the pipeline to use Cognito as its authentication provider.

Create a trust anchor to AWS Private CA. Generate a client certificate to use with AWS IAM Roles Anywhere. Create a new IAM role with the appropriate trust policy that allows the sts:AssumeRole API call. Attach the existing IAM policy to the new IAM role. Configure the pipeline to use the credential helper tool and to reference the client certificate public key to assume the new IAM role.

Answer:

Explanation:

This explanation is based on AWS documentation and best practices but is paraphrased, not a literal extract.

The current CI/CD pipeline uses an IAM user with long-lived access keys stored in GitHub Actions. The new requirement is that pipelines must not use long-lived secret keys. Instead, the solution should provide short-lived credentials with minimal operational overhead.

GitHub Actions natively supports integration with cloud providers using OpenID Connect (OIDC). With OIDC, GitHub acts as an identity provider that can issue OIDC tokens to workflows. On the AWS side, IAM supports configuring an OIDC identity provider and roles that can be assumed by principals presenting valid OIDC tokens through the sts:AssumeRoleWithWebIdentity API. This pattern enables short-lived, automatically rotated credentials for CI/CD jobs without storing long-lived secrets.

In the correct solution (option B), you configure an IAM OIDC identity provider for GitHub in the AWS account. You then create a new IAM role with a trust policy that allows the Github OIDC provider to call sts:AssumeRoleWithWebIdentity, with conditions that restrict which repositories or workflows can assume the role. The existing IAM policy that grants deployment permissions is attached to that role. In GitHub Actions, you update the pipeline configuration to request an OIDC token and assume the IAM role at runtime. Each workflow run receives short-lived credentials without storing static keys, and AWS automatically handles the token verification and temporary credential issuance. This approach is the AWS-recommended pattern for integrating GitHub Actions with AWS without long-lived secrets and has low operational overhead once configured.

Option A uses SAML 2.0, which is typically used for enterprise single sign-on for users, not for GitHub Actions workflows. GitHub does not natively use SAML to obtain AWS credentials for CI/CD pipelines in the same streamlined way as OIDC, and implementing a SAML-based integration would add unnecessary complexity.

Option C introduces Amazon Cognito as an indirection layer. Although Cognito can federate with external identity providers, including social providers, using it as an intermediary to obtain temporary AWS credentials for a machine-to-machine CI/CD pipeline is not necessary when IAM OIDC federation with GitHub is directly supported. This adds additional configuration and operational overhead.

Option D uses IAM Roles Anywhere with client certificates from AWS Private CA. Roles Anywhere is designed for workloads running outside AWS that need to assume IAM roles using X.509 certificates instead of access keys. While technically possible, it requires managing private certificates, trust anchors, and a credential helper tool, which is more complex and operationally heavier than the direct OIDC integration specifically designed for GitHub Actions.

Therefore, configuring an IAM OIDC identity provider for GitHub and creating an IAM role to be assumed via sts:AssumeRoleWithWebIdentity (option B) meets the requirement to replace long-lived secret keys with short-lived credentials with the least operational overhead.

[References:AWS documentation on configuring IAM OpenID Connect identity providers and roles for GitHub Actions integration.AWS security best practices recommending federation and temporary credentials over long-lived IAM user access keys for CI/CD pipelines., , ]

Question 11

A company has created an OU in AWS Organizations for each of its engineering teams Each OU owns multiple AWS accounts. The organization has hundreds of AWS accounts A solutions architect must design a solution so that each OU can view a breakdown of usage costs across its AWS accounts. Which solution meets these requirements?

Options:

Create an AWS Cost and Usage Report (CUR) for each OU by using AWS Resource Access Manager Allow each team to visualize the CUR through an Amazon QuickSight dashboard.

Create an AWS Cost and Usage Report (CUR) from the AWS Organizations management account- Allow each team to visualize the CUR through an Amazon QuickSight dashboard

Create an AWS Cost and Usage Report (CUR) in each AWS Organizations member account Allow each team to visualize the CUR through an Amazon QuickSight dashboard.

Create an AWS Cost and Usage Report (CUR) by using AWS Systems Manager Allow each team to visualize the CUR through Systems Manager OpsCenter dashboards

Answer:

Explanation:

The requirement is to allow each OU (which contains multiple accounts) to view a cost breakdown across its accounts. In an AWS Organizations setup with consolidated billing, the management account is the central place where organization-level cost and usage reporting is configured and aggregated. The Cost and Usage Report is designed to produce the most detailed cost and usage dataset, and it can include charges for linked (member) accounts. A single CUR created from the management account can include all accounts in the organization, and then filtering can be applied to show cost breakdowns per OU or per team.

Once the CUR is delivered to Amazon S3, analytics tools such as Amazon Athena and Amazon QuickSight can be used to create dashboards. Teams can be provided access to the dataset or curated views and can filter by linked account, tags, and other dimensions. With appropriate cost allocation tags and organizational mapping (for example, account-to-OU mapping maintained in reporting logic), each OU can see its consolidated view.

Option B meets the requirements because it creates one CUR centrally from the management account and uses QuickSight for visualization. This approach is scalable for hundreds of accounts and avoids duplicating CUR configuration in each member account.

Option A is incorrect because AWS Resource Access Manager is not used to create CURs per OU. CUR is not an OU-scoped resource created via RAM.

Option C is not operationally efficient because it requires creating and managing CURs in each member account, producing fragmented datasets and significantly increasing overhead at hundreds of accounts. It also makes it harder to generate a single view per OU across accounts.

Option D is incorrect because Systems Manager does not create CURs, and OpsCenter dashboards are not the standard tool for cost and usage reporting.

Therefore, a centrally created CUR in the management account with QuickSight visualization is the correct solution.

[References:AWS documentation on AWS Cost and Usage Report creation from the AWS Organizations management account and inclusion of linked accounts.AWS documentation on using Amazon QuickSight (often with CUR data stored in S3 and queried via Athena) to build cost dashboards and filter by account and other dimensions., , , ]

Question 12

A large company runs workloads in VPCs that are deployed across hundreds of AWS accounts. Each VPC consists to public subnets and private subnets that span across multiple Availability Zones. NAT gateways are deployed in the public subnets and allow outbound connectivity to the internet from the private subnets.

Which set of additional steps should the solutions architect take to meet these requirements?

Options:

Create peering connections between the egress VPC and the spoke VPCs. Configure the required routing to allow access to the internet.

Create a transit gateway, and share it with the existing AWS accounts. Attach existing VPCs to the transit gateway Configure the required routing to allow access to the internet.

Create a transit gateway in every account. Attach the NAT gateway to the transit gateways. Configure the required routing to allow access to the internet.

The application's developer has attached the SecretsManagerReadWnte AWS managed IAM policy to an IAM role The IAM role is associated with the instance profile that is attached to the EC2 instances The solutions architect has invoked the Lambda function for testing

The solutions architect must replace the SecretsManagerReadWnte policy with a new policy that provides least privilege access to the Secrets Manager actions that the application requires

What is the MOST operationally efficient solution that meets these requirements?

Options:

Generate a policy based on CloudTrail events for the IAM role Use the generated policy output to create a new IAM policy Use the newly generated IAM policy to replace the SecretsManagerReadWnte policy that is attached to the IAM role

Create an analyzer in AWS Identity and Access Management Access Analyzer Use the IAM role's Access Advisor findings to create a new IAM policy Use the newly created IAM policy to replace the SecretsManagerReadWnte policy that is attached to the IAM role

Question 21

A company’s web application uses an Amazon API Gateway API, AWS Lambda functions, and Amazon DynamoDB global tables to handle backend requests. The web application is deployed in two AWS Regions in an active-passive model. The company uses Amazon Route 53 for DNS. The web application requires a manual DNS update to fail over to the secondary Region. An analytics Lambda function runs in the same AWS account. The function has caused Lambda concurrency to reach 90% of the current quota on an average day. A recent surge in traffic for the analytics workload resulted in throttled Lambda requests and a poor user experience for the web application users. A solutions architect must increase the reliability of the web application. The solution must use an Amazon CloudWatch alarm to send an Amazon SNS notification when the Lambda concurrency reaches a specific utilization threshold. Which solution will meet these requirements with the LEAST operational overhead?

Options:

Set reserved concurrency on the web application Lambda functions. Implement Route 53 health checks and failover records to route traffic to the secondary Region. Configure the CloudWatch alarm to use the AWS Trusted Advisor ServiceLimitUsage metric and to send the SNS notification.

Question 26

A company runs an application in an on-premises data center. The application gives users the ability to upload media files. The files persist in a file server. The web application has many users. The application server is overutilized, which causes data uploads to fail occasionally. The company frequently adds new storage to the file server. The company wants to resolve these challenges by migrating the application to AWS.

Users from across the United States and Canada access the application. Only authenticated usersshould have the ability to access the application to upload files. The company will consider a solution that refactors the application, and the company needs to accelerate application development.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Use AWS Application Migration Service to migrate the application server to Amazon EC2 instances. Create an Auto Scaling group for the EC2 instances. Use an Application Load Balancer to distribute the requests. Modify the application to use Amazon S3 to persist the files. Use Amazon Cognito to authenticate users.

Use AWS Application Migration Service to migrate the application server to Amazon EC2 instances. Create an Auto Scaling group for the EC2 instances. Use an Application Load Balancer to distribute the requests. Set up AWS IAM Identity Center (AWS Single Sign-On) to give users the ability to sign in to the application. Modify the application to use Amazon S3 to persist the files.

Create a static website for uploads of media files. Store the static assets in Amazon S3. Use AWS AppSync to create an API. Use AWS Lambda resolvers to upload the media files to Amazon S3. Use Amazon Cognito to authenticate users.

Use AWS Amplify to create a static website for uploads of media files. Use Amplify Hosting to serve the website through Amazon CloudFront. Use Amazon S3 to store the uploaded media files. Use Amazon Cognito to authenticate users.

Answer:

Explanation:

The company should use AWS Amplify to create a static website for uploads of media files. The company should use Amplify Hosting to serve the website through Amazon CloudFront. The company should use Amazon S3 to store the uploaded media files. The company should use Amazon Cognito to authenticate users. This solution will meet the requirements with the least operational overhead because AWS Amplify is a complete solution that lets frontend web and mobile developers easily build, ship, and host full-stack applications on AWS, with the flexibility to leverage the breadth of AWS services as use cases evolve. No cloud expertise needed1. By using AWS Amplify, the company can refactor the application to a serverless architecture that reduces operational complexity and costs. AWS Amplify offers the following features and benefits:

Amplify Studio: A visual interface that enables you to build and deploy a full-stack app quickly, including frontend UI and backend.

Amplify CLI: A local toolchain that enables you to configure and manage an app backend with just a few commands.

Amplify Libraries: Open-source client libraries that enable you to build cloud-powered mobile and web apps.

Amplify UI Components: Open-source design system with cloud-connected components for building feature-rich apps fast.

Amplify Hosting: Fully managed CI/CD and hosting for fast, secure, and reliable static and server-side rendered apps.

By using AWS Amplify to create a static website for uploads of media files, the company can leverage Amplify Studio to visually build a pixel-perfect UI and connect it to a cloudbackend in clicks. By using Amplify Hosting to serve the website through Amazon CloudFront, the company can easily deploy its web app or website to the fast, secure, and reliable AWS content delivery network (CDN), with hundreds of points of presence globally. By using Amazon S3 to store the uploaded media files, the company can benefit from a highly scalable, durable, and cost-effective object storage service that can handle any amount of data2. By using Amazon Cognito to authenticate users, the company can add user sign-up, sign-in, and access control to its web app with a fully managed service that scales to support millions of users3.

The other options are not correct because:

Using AWS Application Migration Service to migrate the application server to Amazon EC2 instances would not refactor the application or accelerate development. AWS Application Migration Service (AWS MGN) is a service that enables you to migrate physical servers, virtual machines (VMs), or cloud servers from any source infrastructure to AWS without requiring agents or specialized tools. However, this would not address the challenges of overutilization and data uploads failures. It would also not reduce operational overhead or costs compared to a serverless architecture.

Creating a static website for uploads of media files and using AWS AppSync to create an API would not be as simple or fast as using AWS Amplify. AWS AppSync is a service that enables you to create flexible APIs for securely accessing, manipulating, and combining data from one or more data sources. However, this would require more configuration and management than using Amplify Studio and Amplify Hosting. It would also not provide authentication features like Amazon Cognito.

Setting up AWS IAM Identity Center (AWS Single Sign-On) to give users the ability to sign in to the application would not be as suitable as using Amazon Cognito. AWS Single Sign-On (AWS SSO) is a service that enables you to centrally manage SSO access and user permissions across multiple AWS accounts and business applications. However, this service is designed for enterprise customers who need to manage access for employees or partners across multiple resources. It is not intended for authenticating end users of web or mobile apps.

Question 36

A retail business runs an orders and payments solution that uses more than 100 AWS Lambda functions that are written in Python. As the company's product catalog grows, the company observes that many of the functions time out. The company reconfigures the functions to have the maximum available timeout values, and the company increases memory for the functions. However, the functions continue to time out.

The company investigates the timeout issue and finds that most failures occur when several functions have been chained together, which results in the initial function timing out while it waits for responses. A solutions architect must resolve these timeout issues while maintaining the cost and operational benefits of using Lambda functions.

Which solution will meet these requirements with the MINIMUM amount of application changes?

Options:

Convert the solution to run in containers. Deploy an Amazon EKS cluster and enable auto scaling for the containers.

Rewrite the Lambda functions in Java. Implement Amazon SQS queues between functions.

Convert the solution to use an AWS Step Functions workflow to invoke the Lambda functions. Remove the direct function-to-function invocations.

Combine groups of linked functions together in a single container image. Deploy the container by using Amazon ECS on Amazon EC2 Spot Instances.

Answer:

Explanation:

Comprehensive and Detailed Explanation From Exact Extract:

C is correct because the root cause is synchronous chaining of Lambda functions that causes the initial function to wait and time out. AWS Step Functions is designed to orchestrate multiple steps (including Lambda invocations) with managed state, retries, and timeouts at the workflow level. By moving the chaining logic into a Step Functions state machine and removing direct function-to-function invocations, the initial Lambda no longer needs to remain running while waiting for downstream functions. Step Functions can coordinate the sequence (or parallel branches), handle transient failures with retries/backoff, and maintain execution state without requiring a long-lived “waiting” Lambda invocation. This resolves timeouts while preserving the operational and cost advantages of a serverless Lambda-based architecture and typically requires minimal code change compared to rewriting or migrating platforms.

Why the other options are incorrect:

A: Migrating to containers/EKS is a major architectural change and increases operational overhead, violating “minimum application changes” and the desire to keep Lambda benefits.

B: Rewriting in Java is extensive and unnecessary. Adding SQS between functions changes invocation style and error handling and still requires significant redesign (and does not inherently solve orchestration/branching as cleanly as Step Functions).

D: Grouping functions into containers and running on ECS Spot changes the compute model and introduces more operational overhead and larger application changes than adopting Step Functions.

Question 49

A company runs a workload in the AWS Cloud. The company stores data for the application in an older version of Amazon DocumentDB. Several backend services read and write data to the database continuously throughout all hours of the day. All services connect to the database by using the Amazon DocumentDB cluster endpoint, which is registered as a DNS record in Amazon Route 53.

The company needs to upgrade the database to the latest version of Amazon DocumentDB without losing any data. The company must be able to test and verify the upgrade before the company allows backend services to use the upgraded version. The company has already enabled change streams and set a retention period of 24 hours.

Which solution will meet these requirements?

Options:

Create a new Amazon DocumentDB cluster that runs the latest version. Use the Amazon DocumentDB Index Tool to export existing indexes and import them to the new cluster. Create a new AWS DMS instance and a source and target endpoint. Create a DMS task to migrate the data by using the Migrate and replicate migration type. Test and verify the new cluster. Update the Route 53 record to point to the new cluster.

Create a new Amazon DocumentDB cluster that runs the latest version. Install MongoDB command line interface (CLI) database tools on an Amazon EC2 instance. Use the MongoDB CLI to create a binary export, and import the data to the new Amazon DocumentDB cluster. Test and verify the new cluster. Update the Route 53 record to point to the new cluster.

Create a snapshot of the existing Amazon DocumentDB cluster. Perform an in-place major version upgrade. Modify the existing cluster to the latest version and the latest cluster parameter group. Apply modifications immediately. Test and verify the upgrade.

Create a new Amazon DocumentDB cluster that runs the latest version. Deploy the AWS DataSync agent to an Amazon EC2 instance and activate the agent. Create a new AWS DataSync task in enhanced mode. Start the transfer task to copy data to the new cluster. Test and verify the new cluster. Update the Route 53 record to point to the new cluster.

Answer:

Explanation:

The company needs to upgrade DocumentDB to the latest version with no data loss while allowing continuous reads and writes. The company also must be able to test and verify the upgrade before switching production traffic. This is a classic requirement for performing an upgrade using a blue/green approach: build a new target environment on the new version, keep it in sync with the source, validate it, and then cut over by changing the endpoint (here, Route 53 DNS).

Option A implements this pattern using a new DocumentDB cluster running the latest version and AWS DMS to continuously migrate and replicate changes from the old cluster to the new cluster. Because the workload is continuously changing, a one-time export/import is insufficient; continuous replication is needed to keep the target cluster current during the test period. AWS DMS supports a “migrate and replicate” style of task that performs a full load and then applies ongoing changes (CDC) so the target stays synchronized. The question also states that change streams are enabled with a 24-hour retention period, which supports capturing and applying changes during migration/validation and helps ensure the replication stream can be maintained while testing.

Option A also addresses indexes by using the DocumentDB Index Tool to export and import indexes, which is important because indexes can affect query performance and behavior. After the company validates the new cluster, the cutover is done by updating the Route 53 record to point to the new cluster endpoint, switching all backend services without changing application configuration beyond DNS resolution.

Option B uses MongoDB CLI tools to export/import. This is not suitable for continuous write workloads because export/import is a point-in-time operation and would require downtime or risk data divergence during the test period. It also adds more operational overhead and does not provide continuous replication for the duration of validation.

Option C performs an in-place major version upgrade. That does not satisfy the requirement to test and verify the upgrade before backend services use the upgraded version because the upgrade happens directly on the production cluster. Even though a snapshot exists for rollback, production is still exposed to the upgrade immediately, which violates the requirement for pre-cutover verification.

Option D is incorrect because AWS DataSync transfers files between storage systems such as NFS/SMB and AWS storage services. It is not a database migration or replication service and cannot copy a DocumentDB database in a way that preserves database semantics and supports continuous replication.

Therefore, creating a new DocumentDB cluster, keeping it synchronized using AWS DMS (supported by change stream retention), validating it, and then cutting over via Route 53 DNS update (option A) meets all requirements.

Question 50

A company is planning to migrate its on-premises VMware cluster of 120 VMS to AWS. The VMS have many different operating systems and many custom software

packages installed. The company also has an on-premises NFS server that is 10 TB in size. The company has set up a 10 GbpsAWS Direct Connect connection to AWS for the migration

Which solution will complete the migration to AWS in the LEAST amount of time?

Options:

Export the on-premises VMS and copy them to an Amazon S3 bucket. Use VM Import/Export to create AMIS from the VM images that are stored in Amazon S3.Order an AWS Snowball Edge device. Copy the NFS server data to the device. Restore the NFS server data to an Amazon EC2 instance that has NFS configured.

Configure AWS Application Migration Service with a connection to the VMware cluster. Create a replication job for the VMS. Create an Amazon Elastic File System (Amazon EFS) file system. Configure AWS DataSync to copy the NFS server data to the EFS file system over the Direct Connect connection.

Recreate the VMS on AWS as Amazon EC2 instances. Install all the required software packages. Create an Amazon FSx for Lustre file system. Configure AWS DataSync to copy the NFS server data to the FSx for Lustre file system over the Direct Connect connection.

Order two AWS Snowball Edge devices. Copy the VMS and the NFS server data to the devices. Run VM Import/Export after the data from the devices isloaded to an Amazon S3 bucket. Create an Amazon Elastic File System (Amazon EFS) file system. Copy the NFS server data from Amazon S3 to the EFS file system.

Question 51

A solutions architect is designing a solution to process events. The solution must have the ability to scale in and out based on the number of events that the solution receives. If a processing error occurs, the event must move into a separate queue for review.

Which solution will meet these requirements?

Options:

Send event details to an Amazon Simple Notification Service (Amazon SNS) topic. Configure an AWS Lambda function as a subscriber to the SNS topic to process the events. Add an on-failure destination to the function. Set an Amazon Simple Queue Service (Amazon SQS) queue as the target.

Publish events to an Amazon Simple Queue Service (Amazon SQS) queue. Create an Amazon EC2 Auto Scaling group. Configure the Auto Scaling group to scale in and out based on the ApproximateAgeOfOldestMessage metric of the queue. Configure the application to write failed messages to a dead-letter queue.

Write events to an Amazon DynamoDB table. Configure a DynamoDB stream for the table. Configure the stream to invoke an AWS Lambda function. Configure the Lambda function to process the events.

Publish events to an Amazon EventBridge event bus. Create and run an application on an Amazon EC2 instance with an Auto Scaling group that isbehind an Application Load Balancer (ALB). Set the ALB as the event bus target. Configure the event bus to retry events. Write messages to a dead-letter queue if the application cannot process the messages.

Answer:

Explanation:

Amazon Simple Notification Service (Amazon SNS) is a fully managed pub/sub messaging service that enables users to send messages to multiple subscribers1. Users can sendevent details to an Amazon SNS topic and configure an AWS Lambda function as a subscriber to the SNS topic to process the events. Lambda is a serverless compute service that runs code in response to events and automatically manages the underlying compute resources2. Users can add an on-failure destination to the function and set an Amazon Simple Queue Service (Amazon SQS) queue as the target. Amazon SQS is a fully managed message queuing service that enables users to decouple and scale microservices, distributed systems, and serverless applications3. This way, if a processing error occurs, the event will move into the separate queue for review.

Option B is incorrect because publishing events to an Amazon SQS queue and creating an Amazon EC2 Auto Scaling group will not have the ability to scale in and out based on the number of events that the solution receives. Amazon EC2 is a web service that provides secure, resizable compute capacity in the cloud. Auto Scaling is a feature that helps users maintain application availability and allows them to scale their EC2 capacity up or down automatically according to conditions they define. However, for this use case, using SQS and EC2 will not take advantage of the serverless capabilities of Lambda and SNS.

Option C is incorrect because writing events to an Amazon DynamoDB table and configuring a DynamoDB stream for the table will not have the ability to move events into a separate queue for review if a processing error occurs. Amazon DynamoDB is a fully managed key-value and document database that delivers single-digit millisecond performance at any scale. DynamoDB Streams is a feature that captures data modification events in DynamoDB tables. Users can configure the stream to invoke a Lambda function, but they cannot configure an on-failure destination for the function.

Option D is incorrect because publishing events to an Amazon EventBridge event bus and setting an Application Load Balancer (ALB) as the event bus target will not have the ability to move events into a separate queue for review if a processing error occurs. Amazon EventBridge is a serverless event bus service that makes it easy to connect applications with data from a variety of sources. An ALB is a load balancer that distributes incoming application traffic across multiple targets, such as EC2 instances, containers, IP addresses, Lambda functions, and virtual appliances. Users can configure EventBridge to retry events, but they cannot configure an on-failure destination for the ALB.

Question 52

Question 58

A company hosts a data-processing application on Amazon EC2 instances. The application polls an Amazon Elastic File System (Amazon EFS) file system for newly uploaded files. When a new file is detected, the application extracts data from the file and runs logic to select a Docker container image to process the file. The application starts the appropriate container image and passes the file location as a parameter.

The data processing that the container performs can take up to 2 hours. When the processing is complete, the code that runs inside the container writes the file back to Amazon EFS and exits.

Question 60

A company is running a containerized workload on AWS. The workload consists of several data-processing services that run on a group of Amazon EC2 instances.

The company uploads new data to an Amazon S3 bucket every night. A cron job on each EC2 instance starts the data processing every night. The amount of uploaded data varies. The data-processing tasks can take hours to finish running. After the data is processed, the services remain idle until the next processing window occurs the next night. The company needs a solution to modernize the architecture and reduce the operational overhead.

Which solution will meet these requirements?

Options:

Migrate the workload to AWS Lambda functions that run the container images. Configure an Amazon EventBridge rule to filter S3 events and invoke the Lambda functions when data is uploaded to the S3 bucket.

Migrate the workload to run as tasks in an Amazon ECS cluster that runs on AWS Fargate. Create an AWS Step Functions state machine to invoke the Fargate tasks. Configure S3 Event Notifications to invoke the state machine tasks when data is uploaded to the S3 bucket.

Migrate the workload to run as tasks in an Amazon ECS cluster that runs on AWS Fargate. Create an AWS Step Functions state machine to invoke the Fargate tasks. Configure an Amazon EventBridge rule to invoke the state machine when data is uploaded to the S3 bucket.

Migrate the workload to AWS Lambda functions by packaging the container images as Lambda layers. Configure S3 Event Notifications to invoke the Lambda functions when data is uploaded to the S3 bucket.

Answer:

Explanation:

The workload is containerized, runs for hours, and is event-driven by nightly data arrival in Amazon S3. The current architecture uses EC2 instances and cron jobs, which results in operational overhead (managing instances, patching, scaling, scheduling) and idle compute between processing windows.

A key constraint is that the processing tasks can take hours. AWS Lambda has maximum execution duration limits that make it unsuitable for multi-hour batch processing. Even though Lambda can run container images, it still must complete within Lambda’s runtime limit. Packaging container images as Lambda layers is also not an appropriate pattern for long-running container workloads and adds complexity.

A modern, low-ops approach for long-running, containerized batch jobs is to run containers on AWS Fargate. Fargate removes the need to manage EC2 instances and allows tasks to run for extended periods as needed, scaling based on demand. Because the workload is composed of several data-processing services that likely need orchestration (for example, fan-out, sequencing, retries, parallelism), AWS Step Functions is well suited to coordinate the workflow and invoke the appropriate ECS tasks.

For triggering based on new S3 data, Amazon EventBridge provides a managed, scalable event bus for AWS service events, including S3 object events, and can route events to targets such as Step Functions state machines. Using EventBridge reduces the need for direct point-to-point notification wiring and provides centralized event routing, filtering, and monitoring.

Option C combines all the right elements: it runs the containers as ECS tasks on Fargate to eliminate EC2 management and idle capacity, uses Step Functions to orchestrate tasks that can run for hours, and uses EventBridge to trigger the state machine when new data is uploaded to S3. This replaces the per-instance cron scheduling with an event-driven serverless orchestration model and significantly reduces operational overhead.

Option B is close but is less appropriate as written because S3 Event Notifications are typically configured to send to Amazon SQS, Amazon SNS, or AWS Lambda. Triggering Step Functions directly is more naturally handled through EventBridge rules. EventBridge is also the recommended event routing layer for integrating service events into workflows.

Option A is not suitable because Lambda is not designed for multi-hour processing jobs due to runtime limits.

Option D is incorrect because Lambda layers are for sharing libraries and runtime dependencies, not for packaging multi-hour container workloads. It also still depends on Lambda runtime limits and does not match the operational model for long-running batch processing.

Therefore, option C is the best modernization approach with the least operational overhead.

[References:AWS documentation on AWS Fargate for running container workloads without managing EC2 instances and supporting long-running tasks.AWS documentation on AWS Step Functions for orchestrating long-running workflows, retries, parallelism, and service integrations including Amazon ECS.AWS documentation on Amazon EventBridge for routing Amazon S3 object events to targets such as Step Functions state machines for event-driven architectures., , ]

Question 66

A company is planning to migrate 1,000 on-premises servers to AWS. The servers run on several VMware clusters in the company’s data center. As part of the migration plan, the company wants to gather server metrics such as CPU details, RAM usage, operating system information, and running processes. The company then wants to query and analyze the data.

Which solution will meet these requirements?

Options:

Deploy and configure the AWS Agentless Discovery Connector virtual appliance on the on-premises hosts. Configure Data Exploration in AWS Migration Hub. Use AWS Glue to perform an ETL job against the data. Query the data by using Amazon S3 Select.

Export only the VM performance information from the on-premises hosts. Directly import the required data into AWS Migration Hub. Update any missing information in Migration Hub. Query the data by using Amazon QuickSight.

Create a script to automatically gather the server information from the on-premises hosts. Use the AWS CLI to run the put-resource-attributes command to store the detailed server data in AWS Migration Hub. Query the data directly in the Migration Hub console.

Deploy the AWS Application Discovery Agent to each on-premises server. Configure Data Exploration in AWS Migration Hub. Use Amazon Athena to run predefined queries against the data in Amazon S3.

Question 67

A company is migrating a document processing workload to AWS. The company has updated many applications to natively use the Amazon S3 API to store, retrieve, and modify documents that a processing server generates at a rate of approximately 5 documents every second. After the document processing is finished, customers can download the documents directly from Amazon S3.

During the migration, the company discovered that it could not immediately update the processing server that generates many documents to support the S3 API. The server runs on Linux and requires fast local access to the files that the server generates and modifies. When the server finishes processing, the files must be available to the public for download within 30 minutes.

Which solution will meet these requirements with the LEAST amount of effort?

Options:

Migrate the application to an AWS Lambda function. Use the AWS SDK for Java to generate, modify, and access the files that the company stores directly in Amazon S3.

Set up an Amazon S3 File Gateway and configure a file share that is linked to the document store. Mount the file share on an Amazon EC2 instance by using NFS. When changes occur in Amazon S3, initiate a RefreshCache API call to update the S3 File Gateway.

Configure Amazon FSx for Lustre with an import and export policy. Link the new file system to an S3 bucket. Install the Lustre client and mount the document store to an Amazon EC2 instance by using NFS.

Configure AWS DataSync to connect to an Amazon EC2 instance. Configure a task to synchronize the generated files to and from Amazon S3.

Answer:

Explanation:

The company should configure Amazon FSx for Lustre with an import and export policy. The company should link the new file system to an S3 bucket. The company should install the Lustre client and mount the document store to an Amazon EC2 instance by using NFS. This solution will meet the requirements with the least amount of effort because Amazon FSx for Lustre is a fully managed service that provides a high-performance filesystem optimized for fast processing of workloads such as machine learning, highperformance computing, video processing, financial modeling, and electronic design automation1. Amazon FSx for Lustre can be linked to an S3 bucket and can import data from and export data to the bucket2. The import and export policy can be configured to automatically import new or changed objects from S3 and export new or changed files to S33. This will ensure that the files are available to the public for download within 30 minutes. Amazon FSx for Lustre supports NFS version 3.0 protocol for Linux clients.

The other options are not correct because:

Migrating the application to an AWS Lambda function would require a lot of effort and may not be feasible for the existing server that generates many documents. Lambda functions have limitations on execution time, memory, disk space, and network bandwidth.

Setting up an Amazon S3 File Gateway would not work because S3 File Gateway does not support write-back caching, which means that files written to the file share are uploaded to S3 immediately and are not available locally until they are downloaded again. This would not provide fast local access to the files that the server generates and modifies.

Configuring AWS DataSync to connect to an Amazon EC2 instance would not meet the requirement of making the files available to the public for download within 30 minutes. DataSync is a service that transfers data between on-premises storage systems and AWS storage services over the internet or AWS Direct Connect. DataSync tasks can be scheduled to run at specific times or intervals, but they are not triggered by file changes.

Question 68

A company needs to monitor a growing number of Amazon S3 buckets across two AWS Regions. The company also needs to track the percentage of objects that are

encrypted in Amazon S3. The company needs a dashboard to display this information for internal compliance teams.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Create a new S3 Storage Lens dashboard in each Region to track bucket and encryption metrics. Aggregate data from both Region dashboards into a singledashboard in Amazon QuickSight for the compliance teams.

Deploy an AWS Lambda function in each Region to list the number of buckets and the encryption status of objects. Store this data in Amazon S3. Use AmazonAthena queries to display the data on a custom dashboard in Amazon QuickSight for the compliance teams.

Use the S3 Storage Lens default dashboard to track bucket and encryption metrics. Give the compliance teams access to the dashboard directly in the S3console.

Create an Amazon EventBridge rule to detect AWS Cloud Trail events for S3 object creation. Configure the rule to invoke an AWS Lambda function to recordencryption metrics in Amazon DynamoDB. Use Amazon QuickSight to display the metrics in a dashboard for the compliance teams.

Question 69

A company is using AWS CodePipeline for the CI/CD of an application to an Amazon EC2 Auto Scaling group. All AWS resources are defined in AWS

CloudFormation templates. The application artifacts are stored in an Amazon S3 bucket and deployed to the Auto Scaling group using instance user data scripts.

As the application has become more complex, recent resource changes in the CloudFormation templates have caused unplanned downtime.

How should a solutions architect improve the CI/CD pipeline to reduce the likelihood that changes in the templates will cause downtime?

Options:

Adapt the deployment scripts to detect and report CloudFormation error conditions when performing deployments. Write test plans for a testing team to execute in a non-production environment before approving the change for production.

Implement automated testing using AWS CodeBuild in a test environment. Use CloudFormation change sets to evaluate changes before deployment. Use AWS CodeDeploy to leverage blue/green deployment patterns to allow evaluations and the ability to revert changes, if needed.

Use plugins for the integrated development environment (IDE) to check the templates for errors, and use the AWS CLI to validate that the templates are correct. Adapt the deployment code to check for error conditions and generate notifications on errors. Deploy to a test environment and execute a manual test plan before approving the change for production.

Use AWS CodeDeploy and a blue/green deployment pattern with CloudFormation to replace the user data deployment scripts. Have the operators log in to running instances and go through a manual test plan to verify the application is running as expected.

Question 74

A company ingests and processes streaming market data. The data rate is constant. A nightly process that calculates aggregate statistics is run, and each execution takes about 4 hours to complete. The statistical analysis is not mission critical to the business, and previous data points are picked up on the next execution if a particular run fails.

The current architecture uses a pool of Amazon EC2 Reserved Instances with 1-year reservations running full time to ingest and store the streaming data in attached Amazon EBS volumes. On-Demand EC2 instances are launched each night to perform the nightly processing, accessing the stored data from NFS shares on the ingestion servers, and terminating the nightly processing servers when complete. The Reserved Instance reservations are expiring, and the company needs to determine whether to purchase new reservations or implement a new design.

Which is the most cost-effective design?

Options:

Update the ingestion process to use Amazon Kinesis Data Firehose to save data to Amazon S3. Use a scheduled script to launch a fleet of EC2 On-Demand Instances each night to perform the batch processing of the S3 data. Configure the script to terminate the instances when the processing is complete.

Update the ingestion process to use Amazon Kinesis Data Firehose to save data to Amazon S3. Use AWS Batch with Spot Instances to perform nightlyprocessing with a maximum Spot price that is 50% of the On-Demand price.

Question 77

A company runs a highly available data collection application on Amazon EC2 in the eu-north-1 Region. The application collects data from end-user devices and writes records to an Amazon Kinesis data stream and a set of AWS Lambda functions that process the records. The company persists the output of the record processing to an Amazon S3 bucket in eu-north-1. The company uses the data in the S3 bucket as a data source for Amazon Athena.

The company wants to increase its global presence. A solutions architect must launch the data collection capabilities in the sa-east-1 and ap-northeast-1 Regions. The solutions architect deploys the application, the Kinesis data stream, and the Lambda functions in the two new Regions. The solutions architect keeps the S3 bucket in eu-north-1 to meet a requirement to centralize the data analysis.

During testing of the new setup, the solutions architect notices a significant lag on the arrival of data from the new Regions to the S3 bucket.

Which solution will improve this lag time the MOST?

Options:

In each of the two new Regions, set up the Lambda functions to run in a VPC. Set up an S3 gateway endpoint in that VPC.

Turn on S3 Transfer Acceleration on the S3 bucket in eu-north-1. Change the application to use the new S3 accelerated endpoint when the application uploads data to the S3 bucket.

Create an S3 bucket in each of the two new Regions. Set the application in each new Region to upload to its respective S3 bucket. Set up S3 Cross-Region Replication to replicate data to the S3 bucket in eu-north-1.

Increase the memory requirements of the Lambda functions to ensure that they have multiple cores available. Use the multipart upload feature when the application uploads data to Amazon S3 from Lambda.

Question 78

A company has AWS accounts that are in an organization in AWS rganizations. The company wants to track Amazon EC2 usage as a metric.

The company's architecture team must receive a daily alert if the EC2 usage is more than 10% higher than the average EC2 usage from the last 30 days.

Which solution will meet these requirements?

Options:

Configure AWS Budgets in the organization's management account. Specify a usage type of EC2 running hours. Specify a daily period. Set the budget amount to be 10% more than the reported average usage for the last 30 days from AWS Cost Explorer.

Configure an alert to notify the architecture team if the usage threshold is met. Configure AWS Cost Anomaly Detection in the organization's management account. Configure a monitor type of AWS Service. Apply a filter of Amazon EC2. Configure an alert subscription to notify the architecture team if the usage is 10% more than the average usage for the last 30 days.

Enable AWS Trusted Advisor in the organization's management account. Configure a cost optimization advisory alert to notify the architecture team if the EC2 usage is 10% more than the reported average usage for the last 30 days.

Configure Amazon Detective in the organization's management account. Configure an EC2 usage anomaly alert to notify the architecture team if Detective identifies a usage anomaly of more than 10%.

Answer:

Explanation:

The correct answer is B.

B. This solution meets the requirements because it uses AWS Cost Anomaly Detection, which is a feature of AWS Cost Management that uses machine learning to identify and alert on anomalous spend and usage patterns. By configuring a monitor type of AWS Service and applying a filter of Amazon EC2, the solution can track the EC2 usage as a metric across the organization’s accounts.By configuring an alert subscription with a threshold of 10%, the solution can notify the architecture team via email or AmazonSNS if the EC2 usage is more than 10% higher than the average usage for the last 30 days12

A. This solution is incorrect because it uses AWS Budgets, which is a feature of AWS Cost Management that helps to plan and track costs and usage. However, AWS Budgets does not support usage type of EC2 running hours as a budget type. The only supported usage types are Amazon S3 storage, Amazon EC2 RI utilization, and Amazon EC2 RI coverage. Moreover, AWS Budgets does not support setting the budget amount based on the reported average usage from AWS Cost Explorer.The budget amount has to be a fixed or variable value34

C. This solution is incorrect because it uses AWS Trusted Advisor, which is a feature of AWS Premium Support that provides recommendations to follow best practices for cost optimization, security, performance, and fault tolerance. However, AWS Trusted Advisor does not support configuring custom alerts based on EC2 usage or average usage for the last 30 days.The only supported alerts are based on predefined checks and thresholds that are applied to all services and resources in the account56

D. This solution is incorrect because it uses Amazon Detective, which is a service that helps to analyze and visualize security data to investigate potential security issues. However, Amazon Detective does not support configuring EC2 usage anomaly alerts basedon average usage for the last 30 days.The only supported alerts are based on GuardDuty findings and other security-related events that are detected by machine learning models78

•Inbound requests must be filtered for common vulnerability attacks.

•Rejected requests must be sent to a third-party auditing application.

•All resources should be highly available.

Which solution meets these requirements?

Options:

Configure a Multi-AZ Auto Scaling group using the application's AMI. Create an Application Load Balancer (ALB) and select the previously created Auto Scaling group as the target. Use Amazon Inspector to monitor traffic to the ALB and EC2 instances. Create a web ACL in WAF. Create an AWS WAF using the web ACL and ALB.

Question 81

A company is changing the way that it handles patching of Amazon EC2 instances in its application account. The company currently patches instances over the internet by using a NAT gateway in a VPC in the application account. The company has EC2 instances set up as a patch source repository in a dedicated private VPC in a core account. The company wants to use AWS Systems Manager Patch Manager and the patch source repository in the core account to patch the EC2 instances in the application account. The company must prevent all EC2 instances in the application account from accessing the internet. The EC2 instances in the application account need to access Amazon S3, where the application data is stored. These EC2 instances need connectivity to Systems Manager and to the patch source repository in the private VPC in the core account. Which solution will meet these requirements?

Options:

Create a network ACL that blocks outbound traffic on port 80. Associate the network ACL with all subnets in the application account. In the application account and the core account, deploy one EC2 instance that runs a custom VPN server. Create a VPN tunnel to access the private VPC. Update the route table in the application account.

Create private VIFs for Systems Manager and Amazon S3. Delete the NAT gateway from the VPC in the application account. Create a transit gateway to access the patch source repository EC2 instances in the core account. Update the route table in the core account.

Create VPC endpoints for Systems Manager and Amazon S3. Delete the NAT gateway from the VPC in the application account. Create a VPC peering connection to access the patch source repository EC2 instances in the core account. Update the route tables in both accounts.

Create a network ACL that blocks inbound traffic on port 80. Associate the network ACL with all subnets in the application account. Create a transit gateway to access the patch source repository EC2 instances in the core account. Update the route tables in both accounts.

Answer:

Explanation:

Option C is the correct and most efficient solution, aligning with AWS best practices for secure and private connectivity:

Create VPC Endpoints for Systems Manager and Amazon S3:

Systems Manager VPC Endpoints: By creating interface VPC endpoints for Systems Manager (com.amazonaws.region.ssm, com.amazonaws.region.ec2messages, and com.amazonaws.region.ssmmessages), the EC2 instances can communicate with Systems Manager services without requiring internet access. This setup ensures that patching operations can be conducted securely within the AWS network.

Amazon S3 VPC Endpoint: A gateway VPC endpoint for Amazon S3 (com.amazonaws.region.s3) allows EC2 instances to access S3 buckets privately. This is essential for accessing application data stored in S3 without traversing the public internet.

[Reference: docs.aws.amazon.com, Delete the NAT Gateway:, Removing the NAT gateway ensures that EC2 instances in the application account cannot access the internet, satisfying the requirement to prevent internet access. This action enhances the security posture by eliminating a potential vector for unauthorized outbound traffic., Create a VPC Peering Connection:, Establishing a VPC peering connection between the application account's VPC and the core account's private VPC enables direct, private communication between the EC2 instances in both accounts. This setup allows the application account's EC2 instances to access the patch source repository hosted in the core account securely., Reference: docs.aws.amazon.com, Update Route Tables in Both Accounts:, After setting up the VPC peering connection, it's crucial to update the route tables in both VPCs to allow traffic to flow between them. This configuration ensures that the EC2 instances in the application account can reach the patch source repository in the core account and vice versa., Why Other Options Are Incorrect:, Option A: Implementing a custom VPN solution introduces unnecessary complexity and operational overhead. Additionally, merely blocking outbound traffic on port 80 does not comprehensively prevent internet access, as other ports (e.g., 443 for HTTPS) remain open., Option B: Creating private virtual interfaces (VIFs) is typically associated with AWS Direct Connect, which is not applicable in this scenario. Moreover, using a transit gateway, while feasible, is more complex and may be unnecessary for this use case., Option D: Blocking inbound traffic on port 80 does not prevent outbound internet access. Furthermore, employing a transit gateway adds complexity and cost, which may not be justified given the requirements., Conclusion:, Option C provides a secure, efficient, and cost-effective solution that meets all the specified requirements:, Prevents EC2 instances from accessing the internet., Enables access to Amazon S3 and Systems Manager services via VPC endpoints., Facilitates secure communication with the patch source repository in the core account through VPC peering., This approach leverages AWS's native networking features to maintain a secure and private environment for patch management operations., ]

Question 86

A company has implemented a new security requirement According to the new requirement, the company must scan all traffic from corporate AWS instances in the company's VPC for violations of the company's security policies. As a result of these scans the company can block access to and from specific IP addresses.

To meet the new requirement, the company deploys a set of Amazon EC2 instances in private subnets to serve as transparent proxies The company installs approved proxy server software on these EC2 instances The company modifies the route tables on all subnets to use the corresponding EC2 instances with proxy software as the default route The company also creates security groupsthat are compliant with the security policies and assigns these security groups to the EC2 instances

Despite these configurations, the traffic of the EC2 instances in their private subnets is not being properly forwarded to the internet.

What should a solutions architect do to resolve this issue?

Options:

Disable source'destination checks on the EC2 instances that run the proxy software

Add a rule to the security group that is assigned to the proxy EC2 instances to allow all traffic between instances that have this security group Assign this security group to all EC2 instances in the VPC.

Change the VPC's DHCP options set Set the DNS server options to point to the addresses of the proxy EC2 instances

Assign one additional elastic network interface to each proxy EC2 instance Ensure that one of these network interfaces has a route to the private subnets Ensure that the other network interface has a route to the internet.

Question 87

A company has deployed an application on AWS Elastic Beanstalk. The application uses Amazon Aurora for the database layer.

Question 89

A company developed a pilot application by using AWS Elastic Beanstalk and Java. To save costs during development, the company's development team deployed the application into a single-instance environment. Recent tests indicate that the application consumes more CPU than expected. CPU utilization is regularly greater than 85%, which causes some performance bottlenecks.

A solutions architect must mitigate the performance issues before the company launches the application to production.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Question 90

A company uses an on-premises data analytics platform. The system is highly available in a fully redundant configuration across 12 servers in the company's data center.

The system runs scheduled jobs, both hourly and daily, in addition to one-time requests from users.Scheduled jobs can take between 20 minutes and 2 hours to finish running and have tight SLAs. The scheduled jobs account for 65% of the system usage. User jobs typically finish running in less than 5 minutes and have no SLA. The user jobs account for 35% of system usage. During system failures, scheduled jobs must continue to meet SLAs. However, user jobs can be delayed.

A solutions architect needs to move the system to Amazon EC2 instances and adopt a consumption-based model to reduce costs with no long-term commitments. The solution must maintain high availability and must not affect the SLAs.

Which solution will meet these requirements MOST cost-effectively?

Options:

Split the 12 instances across two Availability Zones in the chosen AWS Region. Run two instances in each Availability Zone as On-Demand Instances with Capacity Reservations. Run four instances in each Availability Zone as Spot Instances.

Split the 12 instances across three Availability Zones in the chosen AWS Region. In one of the Availability Zones, run all four instances as On-Demand Instances with Capacity Reservations. Run the remaining instances as Spot Instances.

A PostgreSQL database has been migrated to Amazon RDS for PostgreSQL. The company expects a significant increase of orders on its platform when a new version of its flagship product is released.

What changes to the current architecture will reduce operational overhead and support the product release?

Options:

Create an EC2 Auto Scaling group behind an Application Load Balancer. Create additional read replicas for the DB instance. Create Amazon Kinesis data streams and configure the application services to use the data streams. Store and serve static content directly from Amazon S3.

Deploy the application on Amazon Elastic Kubernetes Service (Amazon EKS) with AWS Fargate and enable auto scaling behind an Application Load Balancer. Create additional read replicas for the DB instance. Create an Amazon Managed Streaming for Apache Kafka cluster and configure the application services to use the cluster. Store static content in Amazon S3 behind an Amazon CloudFront distribution.

Answer:

Explanation:

The correct answer is D. Deploy the application on Amazon Elastic Kubernetes Service (Amazon EKS) with AWS Fargate and enable auto scaling behind an Application Load Balancer. Create additional read replicas for the DB instance. Create an Amazon Managed Streaming for Apache Kafka cluster and configure the application services to use the cluster. Store static content in Amazon S3 behind an Amazon CloudFront distribution.

Option D meets the requirements of the scenario because it allows you to reduce operational overhead and support the product release by using the following AWS services and features:

Amazon Elastic Kubernetes Service (Amazon EKS) is a fully managed service that allows you to run Kubernetes applications on AWS without needing to install, operate, or maintain your own Kubernetes control plane. You can use Amazon EKS to deploy your containerized application services on a Kubernetes cluster that is compatible with your existing tools and processes.

AWS Fargate is a serverless compute engine that eliminates the need to provision and manage servers for your containers. You can use AWS Fargate as the launch type for your Amazon EKS pods, which are the smallest deployable units of computing in Kubernetes. You can also enable auto scaling for your pods, which allows you to automatically adjust the number of pods based on the demand or custom metrics.

An Application Load Balancer (ALB) is a load balancer that distributes traffic across multiple targets in multiple Availability Zones using HTTP or HTTPS protocols. You can use an ALB to balance the load across your Amazon EKS pods and provide high availability and fault tolerance for your application.

Amazon RDS for PostgreSQL is a fully managed relational database service that supports the PostgreSQL open source database engine. You can create additional read replicas for your DB instance, which are copies of your primary DB instance that can handle read-only queries and improve performance. You can also useread replicas to scale out beyond the capacity of a single DB instance for read-heavy workloads.

Amazon Managed Streaming for Apache Kafka (Amazon MSK) is a fully managed service that makes it easy to build and run applications that use Apache Kafka to process streaming data. Apache Kafka is an open source platform for building real-time data pipelines and streaming applications. You can use Amazon MSK to create and manage a Kafka cluster that is highly available, secure, and compatible with your existing Kafka applications. You can also configure your application services to use the Amazon MSK cluster as a source or destination of streaming data.

Amazon S3 is an object storage service that offers high durability, availability, and scalability. You can store static content such as images, videos, or documents in Amazon S3 buckets, which are containers for objects. You can also serve static content directly from Amazon S3 using public URLs or presigned URLs.

Amazon CloudFront is a fast content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency and high transfer speeds. You can use Amazon CloudFront to create a distribution that caches static content from your Amazon S3 bucket at edge locations closer to your users. This can improve the performance and user experience of your application.

Option A is incorrect because creating an EC2 Auto Scaling group behind an ALB would not reduce operational overhead as much as using AWS Fargate with Amazon EKS, as you would still need to manage EC2 instances for your containers. Creating additional read replicas for the DB instance would not provide high availability or fault tolerance in case of a failure of the primary DB instance, unlike deploying the DB instance in Multi-AZ mode. Creating Amazon Kinesis data streams would not be compatible with your existing Apache Kafka applications, unlike using Amazon MSK.

Option B is incorrect because creating an EC2 Auto Scaling group behind an ALB would not reduce operational overhead as much as using AWS Fargate with Amazon EKS, as you would still need to manage EC2 instances for your containers. Creating Amazon Kinesis data streams would not be compatible with your existing Apache Kafka applications, unlike using Amazon MSK. Storing and serving static content directly from Amazon S3 would not provide optimal performance and user experience, unlike using Amazon CloudFront.

Option C is incorrect because deploying the application on a Kubernetes cluster created on the EC2 instances behind an ALB would not reduce operational overhead as much as using AWS Fargate with Amazon EKS, as you would still need to manage EC2 instances and Kubernetes control plane for your containers. Using Amazon API Gateway to interact with the application would add an unnecessary layer of complexity and cost to your architecture, as you would need to create and maintain an API gateway that proxies requests to your ALB.

Question 93

A company uses an organization in AWS Organizations that has multiple AWS accounts. The accounts host multiple resources that are tagged with a CostCenter tag key. The tag value is the name of the team. The company wants to accurately identify the cost of the resources so that the company can charge each team accordingly.

Which solution meets these requirements?

Options:

Activate the CostCenter user-defined tag in the organization's management account. Configure monthly AWS Cost and Usage Reports to save to an Amazon S3 bucket in the management account. Use the tag breakdown in the report to obtain the total cost for the resources that have the CostCenter tag.

Activate the CostCenter user-defined tag in every member account. Configure monthly AWS Cost and Usage Reports to save to an Amazon S3 bucket in the management account. Create an AWS Lambda function that runs monthly to retrieve the reports and calculate the total cost for the resources that have the CostCenter tag.

Activate the CostCenter user-defined tag in every member account. Schedule a monthly AWS Cost and Usage Report from the management account. Use the tag breakdown in the report to calculate the total cost for the resources that have the CostCenter tag.

Question 94

A financial services company runs a complex, multi-tier application on Amazon EC2 instances and AWS Lambda functions. The application stores temporary data in Amazon S3. The S3 objects are valid for only 45 minutes and are deleted after 24 hours.

The company deploys each version of the application by launching an AWS CloudFormation stack. The stack creates all resources that are required to run the application. When the company deploys and validates a new application version, the company deletes the CloudFormation stack of the old version.

The company recently tried to delete the CloudFormation stack of an old application version, but the operation failed. An analysis shows that CloudFormation failed to delete an existing S3 bucket. A solutions architect needs to resolve this issue without making major changes to the application's architecture.

Which solution meets these requirements?

Options:

Implement a Lambda function that deletes all files from a given S3 bucket. Integrate this Lambda function as a custom resource into the CloudFormation stack. Ensure that the custom resource has a DependsOn attribute that points to the S3 bucket's resource.

Modify the CloudFormation template to provision an Amazon Elastic File System (Amazon EFS) file system to store the temporary files there instead of in Amazon S3. Configure the Lambda functions to run in the same VPC as the file system. Mount the file system to the EC2 instances and Lambda functions.

Modify the CloudFormation stack to create an S3 Lifecycle rule that expires all objects 45 minutes after creation. Add a DependsOn attribute that points to the S3 bucket's resource.

Modify the CloudFormation stack to attach a DeletionPolicy attribute with a value of Delete to the S3 bucket.

Question 95

An AWS customer has a web application that runs on premises. The web application fetches data from a third-party API that is behind a firewall. The third party accepts only one public CIDR block in each client's allow list.

The customer wants to migrate their web application to the AWS Cloud. The application will be hosted on a set of Amazon EC2 instances behind an Application Load Balancer (ALB) in a VPC. The ALB is located in public subnets. The EC2 instances are located in private subnets. NAT gateways provide internet access to the private subnets.

How should a solutions architect ensure that the web application can continue to call the third-parly API after the migration?

Options:

Associate a block of customer-owned public IP addresses to the VPC. Enable public IP addressing for public subnets in the VPC.

Register a block of customer-owned public IP addresses in the AWS account. Create Elastic IP addresses from the address block and assign them lo the NAT gateways in the VPC.

Create Elastic IP addresses from the block of customer-owned IP addresses. Assign the static Elastic IP addresses to the ALB.

Register a block of customer-owned public IP addresses in the AWS account. Set up AWS Global Accelerator to use Elastic IP addresses from the address block. Set the ALB as the accelerator endpoint.

Question 96

A company hosts a software as a service (SaaS) solution on AWS. The solution has an Amazon API Gateway API that serves an HTTPS endpoint. The API uses AWS Lambda functions for compute. The Lambda functions store data in an Amazon Aurora Serverless VI database.

The company used the AWS Serverless Application Model (AWS SAM) to deploy the solution. The solution extends across multiple Availability Zones and has nodisaster recovery (DR) plan.

A solutions architect must design a DR strategy that can recover the solution in another AWS Region. The solution has an R TO of 5 minutes and an RPO of 1 minute.

What should the solutions architect do to meet these requirements?

Options:

Create a read replica of the Aurora Serverless VI database in the target Region. Use AWS SAM to create a runbook to deploy the solution to the target Region. Promote the read replica to primary in case of disaster.

Change the Aurora Serverless VI database to a standard Aurora MySQL global database that extends across the source Region and the target Region. Use AWS SAM to create a runbook to deploy the solution to the target Region.

Question 97

A company is designing a new website that hosts static content. The website will give users the ability to upload and download large files. According to company requirements, all data must be encrypted in transit and at rest. A solutions architect is building the solution by using Amazon S3 and Amazon CloudFront.

Which combination of steps will meet the encryption requirements? (Select THREE.)

Options:

Turn on S3 server-side encryption for the S3 bucket that the web application uses.

Add a policy attribute of "aws:SecureTransport": "true" for read and write operations in the S3 ACLs.

Create a bucket policy that denies any unencrypted operations in the S3 bucket that the web application uses.

Configure encryption at rest on CloudFront by using server-side encryption with AWS KMS keys (SSE-KMS).

Configure redirection of HTTP requests to HTTPS requests in CloudFront.

Use the RequireSSL option in the creation of presigned URLs for the S3 bucket that the web application uses.

Question 98

A company hosts a multi-tier data processing application that consists of a static web application frontend and APIs that are hosted on multiple Amazon EC2 instances. The application stores search data on a single-node Amazon OpenSearch Service cluster that runs on an EC2 instance. The application stores additional data in a PostgreSQL database that runs on another EC2 instance. An NGINX server that is hosted on an EC2 instance serves the web application.

The company has experienced some support issues with the application and wants to modernize the application.

Which solution meets these requirements with the LEAST operational overhead?

Options:

Create an Amazon ECS cluster that runs on AWS Fargate. Configure the ECS cluster to pull images from the Amazon ECR public repositories for OpenSearch Service, PostgreSQL, and NGINX and from a private repository for the APIs.

Host the web application on Amazon CloudFront by using an Amazon S3 origin. Use OpenSearch Service to store the search data and migrate the PostgreSQL database to an Amazon Aurora PostgreSQL cluster. Run the APIs on AWS App Runner.

Create an Amazon EKS cluster that has a managed node group. Configure the EKS cluster to pull images from the Amazon ECR public repositories for OpenSearch Service, PostgreSQL, and NGINX and from a private repository for the APIs.

Configure AWS App Runner to pull images from the Amazon ECR public repositories for OpenSearch Service, PostgreSQL, and NGINX and from a private repository for the APIs. Deploy the images to App Runner.

Answer:

Explanation:

The company’s goal is to modernize the application while minimizing operational overhead. The current architecture relies heavily on self-managed EC2 instances for web serving, APIs, search, and relational data storage. This increases operational burden related to patching, scaling, availability, and troubleshooting.

Option B replaces self-managed components with fully managed AWS services that are purpose-built for each workload type. Hosting the static web application on Amazon S3 with Amazon CloudFront removes the need to manage web servers such as NGINX and provides global content delivery with built-in scalability and high availability. Migrating the search data to Amazon OpenSearch Service eliminates the need to manage an EC2-based OpenSearch node, providing a managed search service with built-in scaling, patching, and monitoring. Migrating PostgreSQL to Amazon Aurora PostgreSQL removes the operational overhead of managing database instances on EC2 and provides managed backups, high availability, and performance optimizations. Running APIs on AWS App Runner further reduces operational effort by abstracting infrastructure management, scaling, and deployment, allowing the team to focus on application code.

Option A still requires running and operating containerized databases and search engines, which is not recommended and does not significantly reduce operational overhead compared to EC2-based deployments. Databases and OpenSearch are better consumed as managed services rather than as containers.

Option C introduces Amazon EKS, which adds significant operational complexity. Even with managed node groups, Kubernetes requires cluster management, networking configuration, upgrades, and ongoing operational expertise. This contradicts the requirement for the least operational overhead.

Option D attempts to run databases and OpenSearch on AWS App Runner. App Runner is designed for stateless web services and APIs, not for stateful services such as databases or search engines. This architecture is not aligned with AWS best practices and would introduce reliability and operational challenges.

Therefore, using managed services such as Amazon CloudFront, Amazon S3, Amazon OpenSearch Service, Amazon Aurora PostgreSQL, and AWS App Runner provides the most modern architecture with the least operational overhead.

Question 99

A company uses an Amazon Redshift cluster to ingest data from various sources. The data is shared with other internal applications for analysis and reporting.

The cluster has eight ra3.4xlarge nodes. Data ingestion runs daily from midnight to 8 AM and takes 3 hours. The cluster has 85% average CPU utilization during ingestion. The cluster uses on-demand node pricing and is paused outside of the 8-hour daily ingestion window. Snapshots are enabled on the cluster.

The company wants to optimize this workload to reduce costs.

Which solution will meet these requirements?

Options:

Create a new Redshift cluster with eight ra3.4xlarge nodes in concurrency scaling mode by using the most recent snapshot from the existing cluster. Modify the internal applications to retrieve data from the new Redshift cluster. Shut down the existing Redshift cluster. Purchase eight 1-year All Upfront Redshift reserved nodes.

Create a new Redshift cluster with six ra3.16xlarge nodes by using the most recent snapshot from the existing cluster. Enable auto scaling. Modify the internal applications to retrieve data from the new Redshift cluster. Shut down the existing Redshift cluster.

Create a new Redshift Serverless endpoint with 64 Redshift Processing Units (RPUs) by using the most recent snapshot from the existing Redshift cluster. Update the internal applications to retrieve data from the new Redshift Serverless endpoint. Delete the existing Redshift cluster.

Configure Redshift Spectrum on the existing Redshift cluster. Set up IAM permissions to allow Redshift Spectrum to access Amazon S3. Unload data from the existing cluster to an S3 bucket. Update the internal applications to query the S3 data.

Answer:

Explanation:

The current Redshift configuration uses eight ra3.4xlarge nodes with on-demand pricing and is paused outside an 8-hour daily window. The ingestion workload runs only 3 hours per day and has about 85% CPU utilization during ingestion, which indicates that the existing node size and count are adequate for performance. The main opportunity is cost optimization for a workload that is time-bound and does not require a continuously running provisioned cluster.

Amazon Redshift Serverless is designed for such intermittent or variable workloads. With Redshift Serverless, you configure compute capacity in terms of Redshift Processing Units (RPUs) and pay per use based on the RPU-hours consumed when queries and data ingestion jobs are actually running. When there is no activity, there is no compute charge. Redshift Serverless can also be created from an existing provisioned Redshift snapshot, allowing an easy migration path from a node-based cluster to a serverless endpoint without re-ingesting or manually moving data.

Option C creates a new Redshift Serverless endpoint with 64 RPUs from the most recent snapshot. This takes advantage of snapshots that already exist on the current cluster. The internal applications are then updated to read from the new serverless endpoint, and the existing cluster is deleted to stop incurring node-based charges. For a workload that runs only a few hours per day, moving to serverless compute is usually more cost-effective than maintaining a provisioned cluster, even if that cluster is paused outside the ingestion window, because serverless eliminates the need to manage cluster sizing and pausing and optimizes billing around actual usage.

Option A proposes staying on provisioned RA3 nodes and additionally purchasing 1-year Reserved Nodes. Reserved Nodes apply discount to node hours whether or not the cluster is paused or fully utilized, and they are designed to be cost-effective for steady, predictable, long-running workloads. For an 8-hour-per-day workload, especially with only 3 hours of intensive ingestion, Reserved Nodes are likely to be less cost-optimal than an on-demand, usage-based serverless model. Also, concurrency scaling is primarily for handling bursty query concurrency, not for cost reduction of a regular ingestion workload.

Option B replaces the existing eight ra3.4xlarge nodes with six ra3.16xlarge nodes and enables auto scaling. ra3.16xlarge provides significantly more capacity per node and is generally more expensive. The original workload already runs at acceptable utilization (about 85% during ingestion), so scaling up to larger nodes is not necessary for performance. Adding auto scaling on top of this likely increases costs and complexity without a clear benefit for a predictable, time-bound daily ingestion pattern.

Option D uses Redshift Spectrum and unloads data from the cluster to Amazon S3 for querying. Redshift Spectrum allows querying data stored in S3 using external tables from within a Redshift cluster, and is charged per amount of data scanned. However, the option still depends on maintaining a Redshift cluster and does not fundamentally optimize the compute cost of the ingestion workload. It also changes query patterns and data access architecture for the internal applications and may increase query cost if large volumes of S3 data are scanned by Spectrum.

Therefore, using Redshift Serverless created from the existing snapshot and paying only for compute usage during ingestion and queries, as described in option C, is the best way to optimize cost for this specific workload pattern.

[References:AWS documentation for Amazon Redshift Serverless concepts such as RPU-based pricing, using snapshots from provisioned clusters to create serverless workgroups, and cost optimization guidance for intermittent and spiky analytics workloads.AWS guidance on reserved node usage and suitability for steady-state provisioned Redshift clusters.AWS descriptions of Amazon Redshift Spectrum and its pricing and use cases for querying data directly in Amazon S3.]

Question 100

A solutions architect is reviewing a company's process for taking snapshots of Amazon RDS DB instances. The company takes automatic snapshots every day and retains the snapshots for 7 days.

The solutions architect needs to recommend a solution that takes snapshots every 6 hours and retains the snapshots for 30 days. The company uses AWS Organizations to manage all of its AWS accounts. The company needs a consolidated view of the health of the RDS snapshots.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Turn on the cross-account management feature in AWS Backup. Create a backup plan that specifies the frequency and retention requirements. Add a tag to the DB instances. Apply the backup plan by using tags. Use AWS Backup to monitor the status of the backups.

Turn on the cross-account management feature in Amazon RDS. Create a snapshot global policy that specifies the frequency and retention requirements. Use the RDS console in the management account to monitor the status of the backups.

Turn on the cross-account management feature in AWS CloudFormation. From the management account, deploy a CloudFormation stack set that contains a backup plan from AWS Backup that specifies the frequency and retention requirements. Create an AWS Lambda function in the management account tomonitor the status of the backups. Create an Amazon EventBridge rule in each account to run the Lambda function on a schedule.

Configure AWS Backup in each account. Create an Amazon Data Lifecycle Manager lifecycle policy that specifies the frequency and retention requirements. Specify the DB instances as the target resource. Use the Amazon Data Lifecycle Manager console in each member account to monitor the status of the backups.

Options:

Configure a DHCP options set with the on-prem NTP server.

Use a custom AMI with Amazon Time Sync.

Deploy a 3rd-party NTP server from Marketplace.

Create an IPsec VPN tunnel to sync over Direct Connect.

Question 102

A company uses an AWS CloudFormation template to deploy an Amazon ECS service into a production environment. The template includes an Amazon S3 bucket that is named by using a common prefix with the CloudFormation stack name.

The company uses the same template to create temporary environments for development and continuous integration. Developers can create environments successfully, but they receive errors from CloudFormation when they attempt to delete the environments. The developers often need to delete and recreate stacks with the same names as part of the development and testing process.

Which combination of steps should a solutions architect take to modify the solution to resolve this issue? (Select TWO.)

Options:

Associate an AWS Lambda function with a CloudFormation custom resource to delete all keys that are present in a given S3 bucket. Implement this custom resource as part of the application's CloudFormation template.

Modify the S3 bucket resource in the CloudFormation template by specifying Delete for the DeletionPolicy attribute. Specify the CAPABILITY_DELETE_NONEMPTY capability to process CloudFormation delete operations.

Modify the S3 bucket resource in the CloudFormation template by specifying Retain for the DeletionPolicy attribute. Configure an AWS Config custom rule to run every 24 hours to identify, empty, and delete buckets that are no longer owned by a CloudFormation stack.

Ensure that CloudFormation operations are being invoked by a role that has s3:DeleteObject permissions on all objects in the bucket.

Modify the S3 bucket resource in the CloudFormation template to configure a bucket policy that grants s3:DeleteObject permissions on all objects in the bucket.

Answer:

A, D

Explanation:

CloudFormation cannot delete an S3 bucket that contains objects. When the developers attempt to delete temporary stacks, the delete operation fails if the associated S3 bucket still has objects. Because the bucket name is derived from the stack name, failed deletions can also prevent re-creation of stacks with the same names until the bucket is manually emptied and deleted. This causes friction for development and continuous integration workflows.

To resolve this, the solution must ensure that, during stack deletion, all objects are removed from the S3 bucket so that CloudFormation can delete the bucket successfully. CloudFormation does not natively support automatic deletion of bucket contents. However, CloudFormation custom resources can be used to perform custom actions during stack lifecycle events.

Option A proposes associating a Lambda function with a CloudFormation custom resource. The custom resource can be invoked during stack deletion to list and delete all objects (and object versions if versioning is enabled) in the specified bucket. Once the bucket is emptied by the Lambda function, the standard CloudFormation deletion process can successfully delete the bucket resource.

In addition to emptying the bucket, the IAM role used by CloudFormation must have permissions to delete objects in the bucket. If CloudFormation uses an execution role that lacks s3:DeleteObject (and potentially s3:ListBucket) permissions, the bucket-cleanup Lambda function or CloudFormation itself would not be able to remove objects. Option D ensures that CloudFormation operations are invoked by a role that has s3:DeleteObject permissions on bucket objects, enabling the custom resource to perform the deletions.

Option B is incorrect because, although DeletionPolicy can be set to Delete, there is no such capability as CAPABILITY_DELETE_NONEMPTY in CloudFormation, and DeletionPolicy alone does not override the S3 service requirement that buckets must be empty before deletion.

Option C’s Retain DeletionPolicy leaves the bucket behind when the stack is deleted. While an external AWS Config rule could clean up stale buckets, it complicates the design and does not directly solve the problem of re-creating stacks with the same bucket name in a predictable, immediate way.

Option E configures a bucket policy to grant s3:DeleteObject permissions, but this is not sufficient alone. CloudFormation still must assume a role with the appropriate permissions. Bucket policy and IAM role permissions must both be considered, but the key action to resolve the deletion failure is to explicitly empty the bucket through a custom resource, as in option A, and ensure the execution role has delete permissions, as in option D.

Therefore, implementing a Lambda-backed custom resource to empty the S3 bucket during stack deletion (option A) and ensuring the CloudFormation execution role has s3:DeleteObject permissions (option D) resolves the deletion errors and allows developers to delete and recreate stacks freely.

[References:AWS documentation on CloudFormation behavior with S3 bucket deletion and the requirement that buckets must be empty before deletion.AWS documentation on CloudFormation custom resources and Lambda-backed custom resources for performing custom actions during stack operations.]

Question 103

A company migrated an application to the AWS Cloud. The application runs on two Amazon EC2 instances behind an Application Load Balancer (ALB). Application data is stored in a MySQL database that runs on an additional EC2 instance. The application's use of the database is read-heavy.

The loads static content from Amazon Elastic Block Store (Amazon EBS) volumes that are attached to each EC2 instance. The static content is updated frequently and must be copied to each EBS volume.

The load on the application changes throughout the day. During peak hours, the application cannot handle all the incoming requests. Trace data shows that the database cannot handle the read load during peak hours.

Which solution will improve the reliability of the application?

Options:

Question 109

A company is expanding. The company plans to separate its resources into hundreds of different AWS accounts in multiple AWS Regions. A solutions architect must recommend a solution that denies access to any operations outside of specifically designated Regions.

Which solution will meet these requirements?

Options:

Create IAM roles for each account. Create IAM policies with conditional allow permissions that include only approved Regions for the accounts.

Create an organization in AWS Organizations. Create IAM users for each account. Attach a policy to each user to block access to Regions where an account cannot deploy infrastructure.

Launch an AWS Control Tower landing zone. Create OUs and attach SCPs that deny access to run services outside of the approved Regions.

Enable AWS Security Hub in each account. Create controls to specify the Regions where an account can deploy infrastructure.

Question 110

A company uses infrastructure as code (IaC) to provision Amazon EC2 instances. The company uses a launch template to implement an EC2 Auto Scaling group to manage traffic increases. The company applies monthly security updates to all EC2 instances in place.

After a recent update that required instance reboots, the Auto Scaling group terminated the instances and launched new, unpatched instances. New instances that the Auto Scaling group launches in response to traffic load are also unpatched. The company must ensure that the Auto Scaling group launches instances that have the latest security patches.

Which combination of solutions will meet this requirement? (Select TWO.)

Options:

Configure the Auto Scaling group termination policy to use the OldestLaunchTemplate setting.

Create a new Auto Scaling group before the next patch maintenance window. Patch and reboot instances in both Auto Scaling groups during the next maintenance window.

Deploy an Application Load Balancer (ALB) in front of the Auto Scaling group. Monitor target group health after instance replacement.

Use AWS Systems Manager to automatically produce patched AMIs. Update the Auto Scaling group launch template. Initiate an instance refresh for the Auto Scaling group.

Deploy a Network Load Balancer (NLB) in front of the Auto Scaling group. Configure termination protection for the instances.

Answer:

C, D

Explanation:

Comprehensive and Detailed Explanation From Exact Extract:

D is required because the only reliable way to ensure newly launched Auto Scaling instances are patched is to make the launch template reference an AMI that already includes the latest security updates (an immutable image approach). AWS Systems Manager can automate building and maintaining patched AMIs (for example, through automated image creation workflows), after which the launch template is updated to the new AMI and the fleet is updated using Instance Refresh. Instance Refresh performs a controlled rolling replacement of instances so that the Auto Scaling group converges to the new AMI baseline.

C complements D by ensuring safe replacement and availability during the refresh/replacement process. Placing an ALB in front of the Auto Scaling group with health checks ensures that only healthy, fully bootstrapped/patched instances receive traffic, and that traffic is drained away from instances being replaced. Monitoring target health confirms the rollout is successful and minimizes risk during patch-driven reboots or instance replacement.

Why the other options are incorrect:

A: A termination policy setting does not ensure new instances are patched. It only affects which instances are terminated first. It does not solve the “launch patched instances” requirement.

B: Running two Auto Scaling groups and continuing in-place patching increases operational overhead and still risks drift and unpatched capacity when scaling occurs outside the maintenance window. It also does not address the core issue: the launch template AMI baseline.

E: NLB + termination protection does not ensure instances are patched at launch. Termination protection can interfere with Auto Scaling’s ability to replace instances, and NLB does not inherently provide the same application-layer health check behavior and deployment safety patterns typically used for rolling replacements (compared to ALB target group health checks).

Question 112

An ecommerce company runs an application on AWS. The application has an Amazon API Gateway API that invokes an AWS Lambda function. The data is stored in an Amazon RDS for PostgreSQL DB instance.

During the company's most recent flash sale, a sudden increase in API calls negatively affected the application's performance. A solutions architect reviewed the Amazon CloudWatch metrics during that time and noticed a significant increase in Lambda invocations and database connections. The CPU utilization also was high on the DB instance.

What should the solutions architect recommend to optimize the application's performance?

Options:

Increase the memory of the Lambda function. Modify the Lambda function to close the database connections when the data is retrieved.

Add an Amazon ElastiCache for Redis cluster to store the frequently accessed data from the RDS database.

Last month, during a promotional sales event, users reported errors and timeouts while adding items to their shopping carts. The operations team recovered the logs created by the web servers and reviewed Aurora DB cluster performance metrics. Some of the web servers were terminated before logs could be collected and the Aurora metrics were not sufficient for query performance analysis.

Which combination of steps must the solutions architect take to improve application performance visibility during peak traffic events? (Choose three.)

Options:

Configure the Aurora MySQL DB cluster to publish slow query and error logs to Amazon CloudWatch Logs.

Implement the AWS X-Ray SDK to trace incoming HTTP requests on the EC2 instances and implement tracing of SQL queries with the X-Ray SDK for Java.

Question 122

A company runs payment gateways in multiple AWS Regions. The company also operates on-premises data centers where the company manages hardware security modules (HSMs) to tokenize sensitive payment data to comply with security regulations.

To process payment transactions within the company's performance SLA, the company requires an automated and centrally managed solution that can provide dedicated private connectivity between the on-premises HSMs and AWS payment services.

Which solution will meet this requirement?

Options:

Use a centrally managed accelerator in AWS Global Accelerator to route traffic from each data center the nearest AWS Region.

Establish AWS Site-to-Site VPN connections between the data centers and AWS. Set up a centrally managed transit gateway and set appropriate routes.

Use AWS CloudHSM to tokenize the sensitive payment data. Deploy CloudHSM in the same private subnet as the payment services workload.

Set up AWS Cloud WAN with AWS Direct Connect attachments between on-premises data centers and AWS.

Answer:

Explanation:

Comprehensive and Detailed Explanation From Exact Extract:

D is correct because the requirement explicitly calls for (1) dedicated private connectivity, (2) automated and centrally managed operation, and (3) connectivity between on-premises data centers and multiple AWS Regions.

AWS Direct Connect provides dedicated private connectivity from on-premises environments to AWS. This is the key differentiator versus internet-based connectivity options when performance and consistency are required to meet strict SLAs.

AWS Cloud WAN provides centralized, policy-based management of a global network across Regions and on-premises attachments. Using Direct Connect attachments to Cloud WAN lets the company centrally define routing/segmentation policies and connect multiple data centers to multiple Regions in a consistent, automated way—well aligned to “automated and centrally managed” requirements for a multi-Region payment platform.

Why the other options are incorrect:

A (Global Accelerator) improves performance for internet-facing endpoints using Anycast and edge routing, but it does not provide private, dedicated connectivity between on-premises networks and AWS services. It is not the right tool for private HSM-to-AWS service connectivity.

B (Site-to-Site VPN + Transit Gateway) can be centrally routed with Transit Gateway, but VPN tunnels run over the public internet and are not “dedicated private connectivity.” They can be acceptable for many cases, but they do not best meet “dedicated private connectivity” and strict SLA expectations compared to Direct Connect.

C (CloudHSM) changes the architecture by moving tokenization into AWS-managed HSM infrastructure. The question states the company manages on-premises HSMs and needs private connectivity between those HSMs and AWS payment services, so replacing them with CloudHSM does not satisfy the stated connectivity requirement.

Question 124

A company is migrating infrastructure for its massive multiplayer game to AWS. The game's application features a leaderboard where players can see rankings in real time. The leaderboard requires microsecond reads and single-digit-millisecond write latencies. The datasets are single-digit terabytes in size and must be available to accept writes in less than a minute if a primary node failure occurs.

The company needs a solution in which data can persist for further analytical processing through a data pipeline.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Create an Amazon ElastiCache (Redis OSS) cluster with cluster mode enabled. Configure the application to interact with the primary node.

Create an Amazon RDS database with a read replica. Configure the application to point writes to the writer endpoint. Configure the application to point reads to the reader endpoint.

Create an Amazon MemoryDB cluster in Multi-AZ mode. Configure the application to interact with the primary node.

Create multiple Redis nodes on Amazon EC2 instances that are spread across multiple Availability Zones. Configure backups to Amazon S3.

Answer:

Explanation:

The workload is a real-time leaderboard that needs extremely low latency: microsecond reads and single-digit millisecond writes. It also needs rapid failover (accepting writes in less than a minute after a primary node failure) and minimal operational overhead. Additionally, the data must be durable enough to persist and be used later for analytics through a data pipeline.

Amazon MemoryDB for Redis is a Redis-compatible, durable, in-memory database service designed for microsecond read latency and low-millisecond write latency while also providing durability through a distributed transaction log. MemoryDB is designed to be a primary database rather than a cache and supports Multi-AZ configurations with fast failover. These characteristics match the leaderboard’s latency requirements and the availability requirement to resume writes quickly after a failure. Because MemoryDB is fully managed, it has less operational overhead than running Redis on EC2.

Option C is the best choice because MemoryDB provides Redis compatibility, in-memory performance, Multi-AZ high availability, and durability that supports data persistence for downstream processing. The durability aspect is especially important for feeding analytics pipelines, because the data is not only cached but is retained as a database record.

Option A is not the best choice because Amazon ElastiCache for Redis is primarily used as a cache. While it can be configured for replication and can achieve low latency, it is not positioned as a durable primary data store in the same way as MemoryDB for Redis. For requirements that explicitly combine extremely low latency with persistence and database-like durability, MemoryDB is the more appropriate managed service with lower operational overhead than building custom durability mechanisms.

Option B is not suitable because Amazon RDS for MySQL typically cannot meet microsecond read latency, and write latencies are usually higher than single-digit milliseconds for non-trivial workloads. Also, read replicas do not provide multi-writer capability and do not ensure sub-minute write availability in all failure scenarios without additional architecture and failover handling.

Option D has the highest operational overhead because it requires the company to operate Redis on EC2: instance management, patching, scaling, replication, failover automation, monitoring, and backup/restore processes. This does not meet the requirement for the least operational overhead compared to fully managed services.

Therefore, an Amazon MemoryDB cluster in Multi-AZ mode provides the required ultra-low latency, rapid failover for write availability, durability for persistence, and least operational overhead.

[References:AWS documentation on Amazon MemoryDB for Redis, including Redis compatibility, microsecond read latency, Multi-AZ availability, fast failover, and durability suitable for primary database use.AWS documentation on the positioning of Amazon ElastiCache for Redis as an in-memory caching service and MemoryDB as a durable in-memory database.]

Question 125

A research company conducts mathematical simulations in the AWS Cloud. The simulations run on several hundred Amazon EC2 Linux instances. If a simulation encounters an issue, an engineer establishes an SSH connection to the affected EC2 instance.

Company policy requires that each EC2 instance session is established with a unique SSH key and that all SSH connections are logged in AWS CloudTrail. CloudTrail is enabled for the company’s account and the AWS Regions that the company uses.

Which solution will meet these requirements?

Options:

Answer:

Launch new EC2 instances. Generate an individual SSH key for each new EC2 instance. Store the SSH key in AWS Secrets Manager. Create a new IAM policy. Attach the IAM policy to the engineers' IAM role with an Allow statement for the GetSecretValue action. Instruct the engineers to retrieve the SSH key from Secrets Manager when the engineers connect through any SSH client.

Answer:

Create an AWS Systems Manager document to run commands on EC2 instances to set a new unique SSH key. Create a new IAM policy. Attach the IAM policy to the engineers' IAM role with an Allow statement to run Systems Manager documents. Instruct the engineers to run the document to set an SSH key and to connect through any SSH client.

Answer:

Launch new EC2 instances without setting up any SSH key for the new EC2 instances. Set up EC2 Instance Connect on each new EC2 instance. Create a new IAM policy. Attach the IAM policy to the engineers' IAM role with an Allow statement for the SendSSHPublicKey action. Instruct the engineers to connect to the EC2 instances by using Instance Connect from the AWS CLI.

Answer:

Set up AWS Secrets Manager to store the EC2 SSH key. Create an AWS Lambda function to create a new SSH key and to call AWS Systems Manager Session Manager to set the SSH key on the EC2 instance. Configure Secrets Manager to use the Lambda function to automatically rotate the SSH key once daily. Instruct the engineers to retrieve the SSH key from Secrets Manager when the engineers connect through any SSH client.

Answer:

Comprehensive and Detailed Explanation From Exact Extract:

C is correct because EC2 Instance Connect is designed to provide per-connection, short-lived SSH access without long-lived shared private keys, and it integrates with IAM so access is controlled and auditable. With EC2 Instance Connect, engineers push a public key for a short time window to the target instance using the SendSSHPublicKey API action. This meets the “unique SSH key per session” intent because the key can be generated per session and injected temporarily instead of being a persistent static key. Additionally, the key injection is performed through an AWS API call, which is recorded in AWS CloudTrail, satisfying the logging requirement for SSH access activity.

Why the other options are incorrect:

Answer:

B: Running a Systems Manager document to set keys creates operational overhead and still does not inherently ensure CloudTrail logs of each SSH connection (the SSM Run Command API calls are logged, but the subsequent SSH login over the network is not an AWS API event). It also risks key persistence beyond a single session.

Answer:

D: Daily rotation is not “unique per session,” and it is complex/operationally heavy. Like A, the SSH login itself is not automatically a CloudTrail event; CloudTrail would capture Secrets Manager and SSM API calls, not the network SSH authentication event.

Question 127

A company needs a highly available database solution for an application. The solution must be able to fail over to a secondary AWS Region with an RPO of 5 minutes and an RTO of 20 minutes. The database is approximately 10 TB in size.

Which solution will meet these requirements?

Options:

Deploy an Amazon Aurora DB cluster and take snapshots of the cluster every 5 minutes. When each snapshot is complete, copy the snapshot to a secondary Region.

Deploy an Amazon RDS Multi-AZ DB cluster with a cross-Region read replica in a secondary Region. Use an Amazon CloudWatch alarm to invoke an AWS Lambda function that promotes the read replica to become the primary in the event of a failure.

Deploy an Amazon Aurora DB cluster in the primary Region. Configure Amazon EventBridge to target Amazon RDS to create a second cluster in the event of a failure. Use AWS DMS to keep the secondary Region in sync with the primary Region.

Deploy an Amazon RDS Multi-AZ DB cluster in the primary Region with a cross-Region read replica in a secondary Region. Configure automated backups and enable automated failover to promote the read replica to become the primary in the secondary Region.

Answer:

Explanation:

The requirements specify cross-Region failover with an RPO of 5 minutes and an RTO of 20 minutes for a large (10 TB) database. Achieving a low RPO in a secondary Region typically requires near-continuous replication, not periodic snapshots. Achieving a 20-minute RTO requires that the standby data store already exists in the secondary Region and can be promoted quickly.

A cross-Region read replica provides continuous asynchronous replication from the primary Region to a replica in the secondary Region. This is the standard managed approach for cross-Region disaster recovery for Amazon RDS engines that support read replicas. With a read replica already running in the secondary Region, failover can be accomplished by promoting the replica to a standalone primary database instance. This supports an RTO target like 20 minutes because the data is already present and the promotion operation is typically faster than restoring from a full snapshot, especially at 10 TB scale.

Option B describes creating an RDS Multi-AZ DB cluster in the primary Region and a cross-Region read replica in the secondary Region. Multi-AZ addresses high availability within the primary Region, while the cross-Region replica addresses disaster recovery. The option also includes automation using CloudWatch alarms and a Lambda function to promote the replica when a failure is detected. This supports the required RTO by reducing manual intervention time and supports the RPO by using continuous replication.

Option A is not practical for RPO 5 minutes at 10 TB. Taking and copying snapshots every 5 minutes would be operationally heavy and would not complete within the required window; snapshot creation and cross-Region copy are not designed for such high-frequency near-real-time DR. It also risks missing the RPO due to snapshot completion time.

Option C introduces unnecessary complexity and additional services. Creating a second cluster only at failure time is not compatible with a 20-minute RTO for a 10 TB database, and using DMS for continuous sync is more development and operational work than using native RDS replication. This is not the least overhead or most direct DR design.

Option D is incorrect as stated because cross-Region read replicas are not automatically failed over and promoted by an “automated failover” feature in the way Multi-AZ failover works within a Region. Automated backups do not provide near-real-time cross-Region recovery to meet a 5-minute RPO. The usual approach for cross-Region is to create the replica and then promote it through a controlled process, which can be automated via monitoring and Lambda as in option B.

Therefore, using a cross-Region read replica with automation to promote it provides the necessary RPO/RTO with a managed service approach.

[References:AWS documentation on Amazon RDS cross-Region read replicas for disaster recovery and replica promotion procedures.AWS documentation on Multi-AZ deployments for high availability within a Region and combining Multi-AZ with cross-Region read replicas for DR.AWS best practices for meeting RPO/RTO using continuous replication rather than periodic snapshots for large databases., , , ]

Question 129

A company is deploying a new application on AWS. The application consists of an Amazon EKS cluster and an Amazon ECR repository. The EKS cluster has an AWS managed node group.

The company's security guidelines state that all resources on AWS must be continuously scanned for security vulnerabilities.

Which solution will meet this requirement with the LEAST operational overhead?

Options:

Activate AWS Security Hub. Configure Security Hub to scan the EKS nodes and the ECR repository.

Activate Amazon Inspector to scan the EKS nodes and the ECR repository.

Launch a new Amazon EC2 instance and install a vulnerability scanning tool from AWS Marketplace. Configure the EC2 instance to scan the EKS nodes. Configure Amazon ECR to perform a basic scan on push.

Install the Amazon CloudWatch agent on the EKS nodes. Configure the CloudWatch agent to scan continuously. Configure Amazon ECR to perform a basic scan on push.

Answer:

Explanation:

The requirement is to continuously scan all AWS resources in this solution for security vulnerabilities with the least operational overhead. The environment includes Amazon EKS worker nodes in a managed node group and an Amazon ECR repository that stores container images used by the EKS cluster.

Amazon Inspector is a managed vulnerability scanning service that integrates directly with multiple AWS resource types. It can automatically discover Amazon EC2 instances (including EKS managed node group instances) and perform continuous vulnerability assessments against them, using software inventory and known CVE databases. Inspector also integrates with Amazon ECR to scan container images for vulnerabilities when images are pushed to the repository and periodically thereafter, providing continuous assessment of image security posture without requiring separate scanners or infrastructure.

By activating Amazon Inspector for the account and region, the service will automatically start tracking supported resources, including EKS-managed EC2 instances and ECR repositories, and will begin scanning them for known vulnerabilities. Findings are provided through the Inspector console and can be integrated with other services such as AWS Security Hub or Amazon EventBridge for further aggregation and automation, but no separate infrastructure deployment or maintenance is required.

Option B, therefore, provides end-to-end vulnerability scanning for both the EKS nodes and the ECR images with minimal operational overhead, because it leverages a fully managed AWS service that automatically discovers and scans supported resources.

Option A is not correct because AWS Security Hub does not itself perform vulnerability scanning. Security Hub aggregates and normalizes security findings from various AWS services, including Amazon Inspector, GuardDuty, and others. It is a security posture management and aggregation service, not a vulnerability scanner.

Option C introduces additional operational overhead by requiring the company to provision, configure, secure, and maintain a separate EC2 instance running a third-party vulnerability scanning tool. While ECR basic scan-on-push can detect some image vulnerabilities, the EC2-based scanner must be managed, updated, and scaled by the customer, which violates the requirement for the least operational overhead when a fully managed alternative exists.

Option D is incorrect because the Amazon CloudWatch agent is used for metrics and log collection from EC2 instances and other environments; it does not perform vulnerability scanning or CVE analysis. Configuring CloudWatch for monitoring and logging does not meet the requirement to continuously scan for security vulnerabilities. ECR basic scans also provide only image-level scanning and do not cover the EKS nodes themselves.

Therefore, enabling Amazon Inspector to scan both the EKS nodes and the ECR repository, as described in option B, is the solution that meets the continuous vulnerability scanning requirement with the least operational overhead.

[References:AWS documentation for Amazon Inspector capabilities including automated discovery and continuous vulnerability scanning for EC2 instances and Amazon ECR images.AWS documentation describing AWS Security Hub as a security findings aggregation and posture management service rather than a vulnerability scanner.AWS documentation for the Amazon CloudWatch agent and its role in collecting metrics and logs, not performing security scans., , ]

Question 130

A company that provisions job boards for a seasonal workforce is seeing an increase in traffic and usage. The backend services run on a pair of Amazon EC2 instances behind an Application Load Balancer with Amazon DynamoDB as the datastore. Application read and write traffic is slow during peak seasons.

Which option provides a scalable application architecture to handle peak seasons with the LEAST development effort?

Options:

Migrate the backend services to AWS Lambda. Increase the read and write capacity of DynamoDB.

Migrate the backend services to AWS Lambda. Configure DynamoDB to use global tables.

Use Auto Scaling groups for the backend services. Use DynamoDB auto scaling.

Use Auto Scaling groups for the backend services. Use Amazon Simple Queue Service (Amazon SQS) and an AWS Lambda function to write to DynamoDB.

Answer:

Explanation:

Option C is correct because using Auto Scaling groups for the backend services allows the company to scale up or down the number of EC2 instances based on the demand and traffic. This way, the backend services can handle more requests during peak seasons without compromising performance or availability. Using DynamoDB auto scaling allows the company to adjust the provisioned read and write capacity of the table or index automatically based on the actual traffic patterns. This way, the table or index can handle sudden increases or decreases in workload without throttling or overprovisioning1.

Option A is incorrect because migrating the backend services to AWS Lambda may require significant development effort to rewrite the code and test the functionality. Moreover, increasing the read and write capacity of DynamoDB manually may not be efficient or cost-effective, as it does not account for the variability of the workload. The company may end up paying for unused capacity or experiencing throttling if the workload exceeds the provisioned capacity1.

Option B is incorrect because migrating the backend services to AWS Lambda may require significant development effort to rewrite the code and test the functionality. Moreover, configuring DynamoDB to use global tables may not be necessary or beneficial for the company, as global tables are mainly used for replicating data across multiple AWS Regions for fast local access and disaster recovery. Global tables do not automatically scale the provisioned capacity of each replica table; they still require manual or auto scaling settings2.

Option D is incorrect because using Amazon Simple Queue Service (Amazon SQS) and an AWS Lambda function to write to DynamoDB may introduce additional complexity and latency to the application architecture. Amazon SQS is a message queue service that decouples and coordinates the components of a distributed system. AWS Lambda is a serverless compute service that runs code in response to events. Using these services may require significant development effort to integrate them with the backend services and DynamoDB. Moreover, they may not improve the read performance of DynamoDB, which may also be affected by high traffic3.

Question 131

A company has a multi-tier web application that runs on a fleet of Amazon EC2 instances behind an Application Load Balancer (ALB). The instances are in an Auto Scaling group. The ALB and the Auto Scaling group are replicated in a backup AWS Region. The minimum value and the maximum value for the Auto Scaling group are set to zero. An Amazon RDS Multi-AZ DB instance stores the application’s data. The DB instance has a read replica in the backup Region. The application presents an endpoint to end users by using an Amazon Route 53 record.

Create an AWS Lambda function in the backup Region to promote the read replica and modify the Auto Scaling group values. Configure Route 53 with a health check that monitors the web application and sends an Amazon Simple Notification Service (Amazon SNS) notification to the Lambda function when the health check status is unhealthy. Update the application’s Route 53 record with a failover policy that routes traffic to the ALB in the backup R

Configure the Auto Scaling group in the backup Region to have the same values as the Auto Scaling group in the primary Region. Reconfigure the application’s Route 53 record with a latency-based routing policy that load balances traffic between the two ALBs. Remove the read replica. Replace the read replica with a standalone RDS DB instance. Configure Cross-Region Replicationbetween the RDS DB instances by using snapshots and Amazon S3.

Configure an endpoint in AWS Global Accelerator with the two ALBs as equal weighted targets. Create an AWS Lambda function in the backup Region to promote the read replica and modify the Auto Scaling group values. Create an Amazon CloudWatch alarm that is based on the HTTPCode_Target_5XX_Count metric for the ALB in the primary Region. Configure the CloudWatch alarm to invoke the Lambda function.

Comprehensive and Detailed Explanation From Exact Extract:

B is correct because the problem is caused by inconsistent query-string casing leading to CloudFront cache misses, and the best place to normalize the request is at the CloudFront edge before cache-key evaluation. CloudFront Functions run at the edge with very low latency and are intended for lightweight request manipulations (for example, normalizing URLs, headers, and query strings) on viewer request events. By sorting query parameters and converting them to lowercase on the viewer request, CloudFront will treat semantically equivalent requests as the same cache key, increasing cache hit ratio and reducing the number of origin calls to API Gateway and downstream Lambda invocations. This directly reduces latency for global users.

Why the other options are less suitable:

A (Lambda@Edge on origin request): Lambda@Edge can also modify requests, but it is heavier-weight than CloudFront Functions for simple normalization logic. Also, doing this on origin request occurs after CloudFront has already decided whether there is a cache hit. If the cache key is still based on the original mixed-case query string at the viewer side, you won’t consistently prevent cache misses. Normalization must happen before cache lookup to maximize cache hits.

C (API Gateway mapping templates): This normalizes the request only after it has already missed in CloudFront and reached the origin. It does not fix CloudFront cache fragmentation, so it does not meet the “minimal latency” goal as effectively.

D (Lambda authorizer): Lambda authorizers are for authorization/authentication decisions. Using an authorizer for query normalization adds unnecessary overhead and still happens at API Gateway (origin), not at CloudFront before cache evaluation.

Question 148

A company uses AWS Organizations for a multi-account setup in the AWS Cloud. The company uses AWS Control Tower for governance and uses AWS Transit Gateway for VPC connectivityacross accounts.

In an AWS application account, the company's application team has deployed a web application that uses AWS Lambda and Amazon RDS. The company's database administrators have a separate DBA account and use the account to centrally manage all the databases across the organization. The database administrators use an Amazon EC2 instance that is deployed in the DBA account to access an RDS database that is deployed in the application account.

The application team has stored the database credentials as secrets in AWS Secrets Manager in the application account. The application team is manually sharing the secrets with the database administrators. The secrets are encrypted by the default AWS managed key for Secrets Manager in the application account. A solutions architect needs to implement a solution that gives the database administrators access to the database and eliminates the need to manually share the secrets.

Which solution will meet these requirements?

Options:

Use AWS Resource Access Manager (AWS RAM) to share the secrets from the application account with the DBA account. In the DBA account, create an IAM role that is named DBA-Admin. Grant the role the required permissions to access the shared secrets. Attach the DBA-Admin role to the EC2 instance for access to the cross-account secrets.

In the application account, create an IAM role that is named DBA-Secret. Grant the role the required permissions to access the secrets. In the DBA account, create an IAM role that is named DBA-Admin. Grant the DBA-Admin role the required permissions to assume the DBA-Secret role in the application account. Attach the DBA-Admin role to the EC2 instance for access to the cross-account secrets.

In the DBA account, create an IAM role that is named DBA-Admin. Grant the role the required permissions to access the secrets and the default AWS managed key in the application account. In the application account, attach resource-based policies to the key to allow access from the DBA account. Attach the DBA-Admin role to the EC2 instance for access to the cross-account secrets.

In the DBA account, create an IAM role that is named DBA-Admin. Grant the role the required permissions to access the secrets in the application account. Attach an SCP to the application account to allow access to the secrets from the DBA account. Attach the DBA-Admin role to the EC2 instance for access to the cross-account secrets.

Question 149

A company is replicating an application in a secondary AWS Region. The application in the primary Region reads from and writes to several Amazon DynamoDB tables. The application also reads customer data from an Amazon RDS for MySQL DB instance.

The company plans to use the secondary Region as part of a disaster recovery plan. The application in the secondary Region must function without dependencies on the primary Region.

Which solution will meet these requirements with the LEAST development effort?

Options:

Configure DynamoDB global tables. Replicate the required tables to the secondary Region. Create a read replica of the RDS DB instance in the secondary Region. Configure the secondary application to use the DynamoDB tables and the read replica in the secondary Region.

Use DynamoDB Accelerator (DAX) to cache the required tables in the secondary Region. Create a read replica of the RDS DB instance in the secondary Region. Configure the secondary application to use DAX and the read replica in the secondary Region.

Configure DynamoDB global tables. Replicate the required tables to the secondary Region. Enable Multi-AZ for the RDS DB instance. Configure the standby replica to be created in the secondary Region. Configure the secondary application to use the DynamoDB tables and the standby replica in the secondary Region.

Set up DynamoDB streams from the primary Region. Process the streams in the secondary Region to populate new DynamoDB tables. Create a read replica of the RDS DB instance in the secondary Region. Configure the secondary application to use the DynamoDB tables and the read replica in the secondary Region.

Answer:

Explanation:

The company needs the application in the secondary Region to operate independently from the primary Region during disaster recovery. That means both the DynamoDB data and the relational customer data must be present and usable in the secondary Region without cross-Region dependencies at runtime. The company also wants the least development effort, which usually means using native managed replication features rather than building custom replication logic.

For DynamoDB, global tables are the managed multi-Region, multi-active replication feature. Global tables replicate changes between Regions automatically and allow applications in each Region to read and write to local DynamoDB tables, removing dependencies on the primary Region.

For the RDS for MySQL database, the straightforward managed approach for cross-Region disaster recovery with minimal development change is to create a cross-Region read replica in the secondary Region. A read replica uses asynchronous replication to keep data up to date. During a disaster recovery event, the company can promote the read replica in the secondary Region to become a standalone primary database instance. This provides a simple, low-development approach for having the data in the secondary Region. The application in the secondary Region can be configured to use the replica endpoint in normal times and can continue operating with the promoted instance during failover.

Option A combines DynamoDB global tables with an RDS read replica in the secondary Region. This is the least development effort because it uses AWS-managed replication for both data stores and requires only configuration changes and endpoint selection in the secondary application.

Option B is not correct because DAX is a caching layer for DynamoDB, not a replication or disaster recovery mechanism. DAX does not replicate DynamoDB tables into another Region and cannot replace having the DynamoDB data present in the secondary Region.

Option C is incorrect because RDS Multi-AZ is a high availability feature within a single Region, using synchronous replication to a standby in another Availability Zone. Multi-AZ does not create a standby in a different Region, and it does not provide cross-Region DR by itself.

Option D is less desirable because it requires custom development and operations: processing DynamoDB streams, building and operating a replication pipeline, and ensuring correctness and ordering across Regions. This is higher development effort than enabling DynamoDB global tables.

Therefore, using DynamoDB global tables plus an RDS read replica in the secondary Region (option A) meets the DR independence requirement with the least development effort.

Configure the Lambda function to run the request-service-quota-increase command to request a service quota increase for EC2 instances.

Create a Service Quotas request template in the management account. Configure the desired service quota increases for EC2 instances.

Create an AWS Config rule in the management account to set the service quota for EC2 instances.

Create an Amazon EventBridge rule to detect creation of a new account. Send the event to an Amazon simple Notification service (Amazon SNS) topic that involves an AWS Lambda function. Configure the Lambda function to run the create-case command to request a service quota increase for EC2 instances.

Question 152

A company uses a software package for surveys. During surveys, data is uploaded from a field operator's device to an Amazon S3 bucket. A custom application that runs on several Amazon EC2 instances polls the S3 bucket for new data. When new data is available, the software processes the data.

The data uploads are infrequent. The processing software can take up to 25 minutes to analyze each data upload. The company wants to optimize the application workflow to process the S3 data.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Modify the application to accept new S3 object keys as inputs. Containerize the application. Deploy the container to an Amazon ECS cluster that uses the AWS Fargate launch type. Configure S3 bucket notifications to send events to Amazon EventBridge when new objects are uploaded. Create an EventBridge rule that invokes an ECS task to run the application when a new S3 object event occurs.

Modify the application to accept new S3 object keys as inputs. Containerize the application. Deploy the container image to AWS Lambda functions. Create a new AWS Step Functions state machine to invoke the Lambda functions. Configure the state machine with a Task state that calls the Lambda functions. Set the Task state's Timeout property to 30 minutes.

Modify the application to accept new S3 object keys as inputs. Move the application from EC2 instances to Amazon ECS by using the EC2 capacity provider. Create an AWS Glue crawler to check the S3 bucket and invoke the application. Configure the application to process the data when the data is uploaded to Amazon S3.

Modify the application to use HTTP to poll new S3 object keys that reference data to process. Containerize the application. Deploy the container image to AWS Lambda functions. Configure S3 bucket notifications to send events to Amazon EventBridge when new objects are uploaded. Create an EventBridge rule that invokes the Lambda functions to post the new objects to HTTP endpoints by using fan-out.

Question 153

A company that uses AWS Organizations allows developers to experiment on AWS. As part of the landing zone that the company has deployed, developers use their company email address to request an account. The company wants to ensure that developers are not launching costly services or running services unnecessarily. The company must give developers a fixed monthly budget to limit their AWS costs.

Which combination of steps will meet these requirements? (Choose three.)

Options:

Create an SCP to set a fixed monthly account usage limit. Apply the SCP to the developer accounts.

Use AWS Budgets to create a fixed monthly budget for each developer's account as part of the account creation process.

Create an SCP to deny access to costly services and components. Apply the SCP to the developer accounts.

Create an IAM policy to deny access to costly services and components. Apply the IAM policy to the developer accounts.

Create an AWS Budgets alert action to terminate services when the budgeted amount is reached. Configure the action to terminate all services.

Create an AWS Budgets alert action to send an Amazon Simple Notification Service (Amazon SNS) notification when the budgeted amount is reached. Invoke an AWS Lambda function to terminate all services.

Answer:

B, C, F

Explanation:

Option A is incorrect because creating an SCP to set a fixed monthly account usage limit is not possible. SCPs are policies that specify the services and actions that users and roles can use in the member accounts of an AWS Organization. SCPscannot enforce budget limits or prevent users from launching costly services or running services unnecessarily1

Option B is correct because using AWS Budgets to create a fixed monthly budget for each developer’s account as part of the account creation process meets the requirement of giving developers a fixed monthly budget to limit their AWS costs. AWS Budgets allows you to plan your service usage, service costs, and instance reservations. You can create budgets that alert you when your costs or usage exceed (or are forecasted to exceed) your budgeted amount2

Option C is correct because creating an SCP to deny access to costly services and components meets the requirement of ensuring that developers are not launching costly services or running services unnecessarily. SCPs can restrict access to certain AWS services or actions based on conditions such as region, resource tags, or request time. For example, an SCP can deny access to Amazon Redshift clusters or Amazon EC2 instances with certain instance types1

Option D is incorrect because creating an IAM policy to deny access to costly services and components is not sufficient to meet the requirement of ensuring that developers are not launching costly services or running services unnecessarily. IAM policies can only control access to resources within a single AWS account. If developers have multiple accounts or can create new accounts, they can bypass the IAMpolicy restrictions. SCPs can apply across multiple accounts within an AWS Organization and prevent users from creating new accounts that do not comply with the SCP rules3

Option E is incorrect because creating an AWS Budgets alert action to terminate services when the budgeted amount is reached is not possible. AWS Budgets alert actions can only perform one of the following actions: apply an IAM policy, apply an SCP, or send a notification through Amazon SNS.AWS Budgets alert actions cannot terminate services directly.

Option F is correct because creating an AWS Budgets alert action to send an Amazon SNS notification when the budgeted amount is reached and invoking an AWS Lambda function to terminate all services meets the requirement of giving developers a fixed monthly budget to limit their AWS costs. AWS Budgets alert actions can send notifications through Amazon SNS when a budget threshold is breached. Amazon SNS can trigger an AWS Lambda function that can perform custom logic such as terminating all services in the developer’s account. This way, developers cannot exceed their budget limit and incur additional costs.

All domains and target URLs are defined in a JSON document. All DNS records are managed by Amazon Route 53.

A solutions architect must implement a redirect service that accepts HTTP and HTTPS requests.

Which combination of steps should the solutions architect take to meet these requirements with the LEAST amount of operational effort? (Choose three.)

Options:

Create a dynamic webpage that runs on an Amazon EC2 instance. Configure the webpage to use the JSON document in combination with the event message to look up and respond with a redirect URL.

Create an Application Load Balancer that includes HTTP and HTTPS listeners.

Create an AWS Lambda function that uses the JSON document in combination with the event message to look up and respond with a redirect URL.

Use an Amazon API Gateway API with a custom domain to publish an AWS Lambda function.

Create an Amazon CloudFront distribution. Deploy a Lambda@Edge function.

Create an SSL certificate by using AWS Certificate Manager (ACM). Include the domains as Subject Alternative Names.

Question 155

A company is deploying a new API to AWS. The API uses Amazon API Gateway with a Regional API endpoint and an AWS Lambda function for hosting. The API retrieves data from an external vendor API, stores data in an Amazon DynamoDB global table, and retrieves data from the DynamoDB global table. The API key for the vendor's API is stored in AWS Secrets Manager and is encrypted with a customer managed key in AWS Key Management Service (AWS KMS). The company has deployed its own API into a single AWS Region.

A solutions architect needs to change the API components of the company's API to ensure that the components can run across multiple Regions in an active-active configuration.

Which combination of changes will meet this requirement with the LEAST operational overhead? (Choose three.)

Options:

Deploy the API to multiple Regions. Configure Amazon Route 53 with custom domain names that route traffic to each Regional API endpoint. Implement a Route 53 multivalue answer routing policy.

Create a new KMS multi-Region customer managed key. Create a new KMS customer managed replica key in each in-scope Region.

Replicate the existing Secrets Manager secret to other Regions. For each in-scope Region's replicated secret, select the appropriate KMS key.

Create a new AWS managed KMS key in each in-scope Region. Convert an existing key to a multi-Region key. Use the multi-Region key in other Regions.

Create a new Secrets Manager secret in each in-scope Region. Copy the secret value from the existing Region to the new secret in each in-scope Region.

Modify the deployment process for the Lambda function to repeat the deployment across in-scope Regions. Turn on the multi-Region option for the existing API. Select the Lambda function that is deployed in each Region as the backend for the multi-Region API.

Answer:

A, B, C

Explanation:

The combination of changes that will meet the requirement with the least operational overhead are:

A. Deploy the API to multiple Regions. Configure Amazon Route 53 with custom domain names that route traffic to each Regional API endpoint.Implement a Route 53 multivalue answer routing policy.

B. Create a new KMS multi-Region customer managed key. Create a new KMS customer managed replica key in each in-scope Region.

C. Replicate the existing Secrets Manager secret to other Regions. For each in-scope Region’s replicated secret, select the appropriate KMS key.

These changes will enable the company to have an active-active configuration for its API across multiple Regions, while minimizing the complexity and cost of managing the secrets and keys.

A. This change will allow the company to use Route 53 to distribute traffic across multiple Regional API endpoints, based on the availability and latency of each endpoint.This will improve the performance and availability of the API for global customers12

B. This change will allow the company to use KMS multi-Region keys, which are KMS keys in different Regions that can be used interchangeably.This will simplify the encryption and decryption of secrets across Regions, as the same key material and key ID can be used in any Region34

C. This change will allow the company to use Secrets Manager replication, which replicates the encrypted secret data and metadata across the specified Regions.This will ensure that the secrets are consistent and accessible in any Region, andthat any update made to the primary secret will be propagated to the replica secrets automatically56

Configure an Aurora global database in the primary Region. Enable write forwarding to the secondary Region.

Use an Aurora DB cluster that has multiple writer instances in the primary Region. Create a secondary Aurora DB instance in the secondary Region. Enable cross-Region writes between the DB clusters.

Answer:

A, D, E

Explanation:

The company is building an active-active, multi-Region architecture for an ECS-based web application behind ALBs, with shared container images in ECR and a relational database in Aurora MySQL. The goal is to duplicate the setup in a second Region with minimal operational overhead while allowing minor replication latency.

A is required because ACM certificates are Regional for use with Regional resources like an Application Load Balancer. An ALB in the secondary Region needs an ACM certificate that exists in that same Region to terminate HTTPS. Requesting (or importing) a certificate in the secondary Region and attaching it to the ALB HTTPS listener is the standard managed approach with low operational overhead.

B is not correct because ACM certificates are not shared “across Regions” for direct use by a Regional ALB in another Region. Sharing via AWS RAM is used for sharing resources across accounts within a Region (and for supported resource types), but it does not provide a mechanism to use an ACM certificate issued in one Region directly on an ALB in a different Region.

D is required because the application runs in both Regions and must be able to pull container images locally with minimal operational work. Amazon ECR supports cross-Region replication so images pushed in the primary Region can be replicated automatically to the secondary Region’s ECR repositories. This avoids building custom copy pipelines and reduces the chance of drift. Once replication is enabled, updating images in the primary Region can automatically populate the secondary Region repository.

C is not the best fit. A VPC endpoint for ECR is about private connectivity to ECR within a Region. It does not solve the multi-Region image availability problem by itself, and it introduces the idea of pulling images from the primary Region, which is unnecessary and less optimal when cross-Region replication can keep images local to each Region.

E is required because the database must support multi-Region application operation with tolerable replication latency. Aurora Global Database is the managed feature designed to replicate an Aurora cluster to a secondary Region with low-latency replication and minimal operational overhead compared to custom replication. Enabling write forwarding allows applications in the secondary Region to send write requests to the secondary cluster endpoint, with Aurora forwarding those writes to the primary writer. This reduces application changes compared to forcing all writes to go directly to the primary Region endpoints, and it supports an active-active application deployment pattern where both Regions can accept traffic.

F is not correct because “cross-Region writes between DB clusters” and “multiple writer instances in the primary Region” do not provide a managed, multi-Region, multi-writer Aurora design as described. Aurora’s managed multi-Region pattern is Aurora Global Database with a single primary writer in one Region (with the option to promote a secondary Region during failover) and optional write forwarding from a secondary Region to the primary. The option’s described cross-Region multi-writer behavior is not a standard supported Aurora configuration and would not be the least operational overhead approach.

Therefore, the least operational overhead combination that correctly addresses HTTPS termination in the secondary Region, image availability in both Regions, and managed multi-Region database replication is A, D, and E.

Question 169

A company’s solutions architect is evaluating an AWS workload that was deployed several years ago. The application tier is stateless and runs on a single large Amazon EC2 instance that was launched from an AMI. The application stores data in a MySOL database that runs on a single EC2 instance.

The CPU utilization on the application server EC2 instance often reaches 100% and causes the application to stop responding. The company manually installs patches on the instances. Patching has caused

downtime in the past. The company needs to make the application highly available.

Which solution will meet these requirements with the LEAST development time?

Options:

Move the application tier to AWS Lambda functions in the existing VPC. Create an Application Load Balancer to distribute traffic across theLambda functbns. Use Amazon GuardDuty to scan the Lambda functions. Migrate the database to Amazon DocumentDB (with MongoDB compatibility).

Question 171

A company runs an intranet application on premises. The company wants to configure a cloud backup of the application. The company has selected AWS Elastic Disaster Recovery for this solution.

The company requires that replication traffic does not travel through the public internet. The application also must not be accessible from the internet. The company does not want this solution to consume all available network bandwidth because other applications require bandwidth.

Which combination of steps will meet these requirements? (Select THREE.)

Options:

Create a VPC that has at least two private subnets, two NAT gateways, and a virtual private gateway.

Create a VPC that has at least two public subnets, a virtual private gateway, and an internet gateway.

Create an AWS Site-to-Site VPN connection between the on-premises network and the target AWS network.

Create an AWS Direct Connect connection and a Direct Connect gateway between the on-premises network and the target AWS network.

During configuration of the replication servers, select the option to use private IP addresses for data replication.

During configuration of the launch settings for the target servers, select the option to ensure that the Recovery instance's private IP address matches the source server's private IP address.

Answer:

B, D, E

Explanation:

AWS Elastic Disaster Recovery (AWS DRS) is a service that minimizes downtime and data loss with fast, reliable recovery of on-premises and cloud-based applications using affordable storage, minimal compute, and point-in-time recovery1. Users can set up AWS DRS on their source servers to initiate secure data replication to a staging area subnet in their AWS account, in the AWS Region they select. Users can then launch recovery instances on AWS within minutes, using the most up-to-date server state or a previous point in time.

To configure a cloud backup of the application with AWS DRS, users need to create a VPC that has at least two public subnets, a virtual private gateway, and an internet gateway. AVPC is a logically isolated section of the AWS Cloud where users can launch AWS resources in a virtual network that they define2. A public subnet is a subnet that has a route to an internet gateway3. A virtualprivate gateway is the VPN concentrator on the Amazon side of the Site-to-Site VPN connection4. An internet gateway is a horizontally scaled, redundant, and highly available VPC component that allows communication between instances in the VPC and the internet. Users need to create at least two public subnets for redundancy and high availability. Users need to create a virtual private gateway and attach it to the VPC to enable VPN connectivity between the on-premises network and the target AWS network. Users need to create an internet gateway and attach it to the VPC to enable internet access for the replication servers.

To ensure that replication traffic does not travel through the public internet, users need to create an AWS Direct Connect connection and a Direct Connect gateway between the on-premises network and the target AWS network. AWS Direct Connect is a service that establishes a dedicated network connection from an on-premises network to one or more VPCs. A Direct Connect gateway is a globally available resource that allows users to connect multiple VPCs across different Regions to their on-premises networks using one or more Direct Connect connections. Users need to create an AWS Direct Connect connection between their on-premises network and an AWS Region. Users need to create a Direct Connect gateway and associate it with their VPC and their Direct Connect connection.

To ensure that the application is not accessible from the internet, users need to select the option to use private IP addresses for data replication during configuration of the replication servers. This option configures the replication servers with private IP addresses only, without assigning any public IP addresses or Elastic IP addresses. This way, the replication servers can only communicate with other resources within the VPC or through VPN connections.

Option A is incorrect because creating a VPC that has at least two private subnets, two NAT gateways, and a virtual private gateway is not necessary or cost-effective. A private subnet is a subnet that does not have a route to an internet gateway3. A NAT gateway is a highly available, managed Network Address Translation (NAT) service that enables instances in a private subnet to connect to the internet or other AWS services, but prevents the internet from initiating connections with those instances. Users do not need to createprivate subnets or NAT gateways for this use case, as they can use public subnets with private IP addresses for data replication.

Option C is incorrect because creating an AWS Site-to-Site VPN connection between the on-premises network and the target AWS network will not ensure that replication traffic does not travel through the public internet. A Site-to-Site VPN connection consists of two VPN tunnels between an on-premises customer gateway device and a virtual private gateway in your VPC4. The VPN tunnels are encrypted using IPSec protocols, but they still use public IP addresses for communication. Users need to use AWS Direct Connect instead of Site-to-Site VPN for this use case.

Option F is incorrect because selecting the option to ensure that the Recovery instance’s private IP address matches the source server’s private IP address during configuration of the launch settings for the target servers will not ensure that the application is not accessible from the internet. This option configures the Recovery instance with an identical private IP address as its source server when launched in drills or recovery mode. However, this option does not prevent assigning public IP addresses or Elastic IP addresses to the Recovery instance. Users need to select the option to use private IP addresses for data replication instead.

Question 173

A flood monitoring agency has deployed more than 10.000 water-level monitoring sensors. Sensors send continuous data updates, and each update is less than 1 MB in size. The agency has a fleet of on-premises application servers. These servers receive upda.es 'on the sensors, convert the raw data into a human readable format, and write the results loan on-premises relational database server. Data analysts then use simple SOL queries to monitor the data.

The agency wants to increase overall application availability and reduce the effort that is required to perform maintenance tasks These maintenance tasks, which include updates and patches to the application servers, cause downtime. While an application server is down, data is lost from sensors because the remaining servers cannot handle the entire workload.

The agency wants a solution that optimizes operational overhead and costs. A solutions architect recommends the use of AWS loT Core to collect the sensor data.

What else should the solutions architect recommend to meet these requirements?

Options:

Send the sensor data to Amazon Kinesis Data Firehose. Use an AWS Lambda function to read the Kinesis Data Firehose data, convert it to .csv format, and insert it into an Amazon Aurora MySQL DB instance. Instruct the data analysts to query the data directly from the DB instance.

An application is using an Amazon RDS for MySQL Multi-AZ DB instance in the us-east-1 Region. After a failover test, the application lost the connections to the database and could not re-establish the connections. After a restart of the application, the application re-established the connections.

A solutions architect must implement a solution so that the application can re-establish connections to the database without requiring a restart.

Which solution will meet these requirements?

Options:

Create an Amazon Aurora MySQL Serverless v1 DB instance. Migrate the RDS DB instance to the Aurora Serverless v1 DB instance. Update the connection settings in the application to point to the Aurora reader endpoint.

Install the latest Open Database Connectivity (ODBC) driver for the application. Update the connection settings in the application to point to the Athena endpoint

Question 176

A company has migrated its forms-processing application to AWS. When users interact with the application, they upload scanned forms as files through a web application. A database stores user metadata and references to files that are stored in Amazon S3. The web application runs on Amazon EC2 instances and an Amazon RDS for PostgreSQL database.

When forms are uploaded, the application sends notifications to a team through Amazon Simple Notification Service (Amazon SNS). A team member then logs in and processes each form. The team member performs data validation on the form and extracts relevant data before entering the information into another system that uses an API.

A solutions architect needs to automate the manual processing of the forms. The solution must provide accurate form extraction, minimize time to market, and minimize long-term operational overhead.

Which solution will meet these requirements?

Options:

Develop custom libraries to perform optical character recognition (OCR) on the forms. Deploy the libraries to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster as an application tier. Use this tier to process the forms when forms are uploaded. Store the output in Amazon S3. Parse this output by extracting the data into an Amazon DynamoDB table. Submit the data to the target system's API. Host the new application tier on EC2 instance

Extend the system with an application tier that uses AWS Step Functions and AWS Lambda. Configure this tier to use artificial intelligence and machine learning (AI/ML) models that are trained and hosted on an EC2 instance to perform optical character recognition (OCR) on the forms when forms are uploaded. Store the output in Amazon S3. Parse this output by extracting the data that is required within the application tier. Submit the data to

Host a new application tier on EC2 instances. Use this tier to call endpoints that host artificial intelligence and machine learning (Al/ML) models that are trained and hosted in Amazon SageMaker to perform optical character recognition (OCR) on the forms. Store the output in Amazon ElastiCache. Parse this output by extracting the data that is required within the application tier. Submit the data to the target system's API.

Extend the system with an application tier that uses AWS Step Functions and AWS Lambda. Configure this tier to use Amazon Textract and Amazon Comprehend to perform optical character recognition (OCR) on the forms when forms are uploaded. Store the output in Amazon S3.

Question 177

A company operates a proxy server on a fleet of Amazon EC2 instances. Partners in different countries use the proxy server to test the company's functionality. The EC2 instances are running in a VPC. and the instances have access to the internet.

The company's security policy requires that partners can access resources only from domains that the company owns.

Which solution will meet these requirements?

Options:

Create an Amazon Route 53 Resolver DNS Firewall domain list that contains the allowed domains. Configure a DNS Firewall rule group with a rule that has a high numeric value that blocks all requests. Configure a rule that has a low numeric value that allows requests for domains in the allowed list. Associate the rule group with the VPC.

Create an Amazon Route 53 Resolver DNS Firewall domain list that contains the allowed domains. Configure a Route 53 outbound endpoint. Associate the outbound endpoint with the VPC. Associate the domain list with the outbound endpoint.

Create an Amazon Route 53 traffic flow policy to match the allowed domains. Configure the traffic flow policy to forward requests that match to the Route 53 Resolver. Associate the traffic flow policy with the VPC.

Create an Amazon Route 53 outbound endpoint. Associate the outbound endpoint with the VPC. Configure a Route 53 traffic flow policy to forward requests for allowed domains to the outbound endpoint. Associate the traffic flow policy with the VPC.

Answer:

Explanation:

The company should create an Amazon Route 53 Resolver DNS Firewall domain list that contains the allowed domains. The company should configure a DNS Firewall rule group with a rule that has a high numeric value that blocks all requests. The company should configure a rule that has a low numeric value that allows requests for domains in the allowed list. The company should associate the rule group with the VPC. This solution will meet the requirements because Amazon Route 53 Resolver DNS Firewall is a feature that enables you to filter and regulate outbound DNS traffic for your VPC. You can create reusable collections of filtering rules in DNS Firewall rule groups and associate them with your VPCs. You can specify lists of domain names to allow or block, and you can customize theresponses for the DNS queries that you block1. By creating a domain list with the allowed domains and a rule group with rules to allow or block requests based on the domain list, the company can enforce its security policy and control access to sites.

The other options are not correct because:

Configuring a Route 53 outbound endpoint and associating it with the VPC would not help with filtering outbound DNS traffic. A Route 53 outbound endpoint is a resource that enables you to forward DNS queries from your VPC to your networkover AWS Direct Connect or VPN connections2.It does not provide any filtering capabilities.

Creating a Route 53 traffic flow policy to match the allowed domains would not help with filtering outbound DNS traffic. A Route 53 traffic flow policy is a resource that enables you to route traffic based on multiple criteria, such as endpoint health, geographic location, and latency3.It does not provide any filtering capabilities.

Creating a Gateway Load Balancer (GWLB) would not help with filtering outbound DNS traffic. A GWLB is a service that enables you to deploy, scale, and manage third-party virtual appliances such as firewalls, intrusion detection and prevention systems, and deep packet inspection systems in the cloud4.It does not provide any filtering capabilities.

Question 178

A company stores application data in many Amazon S3 buckets in one AWS account. Some of the S3 buckets contain sensitive data. The company does not have data inventory for the S3 buckets. The company uses server-side encryption with Amazon S3 managed keys (SSE-S3) to encrypt all data in the S3 buckets.

A solutions architect must design a solution to encrypt sensitive data with a key that only administrators can access.

Which solution will meet these requirements?

Options:

Use Amazon Inspector to determine which S3 buckets contain sensitive data. Create a new AWS KMS customer managed key and a key policy that provides access to administrators only. Set default S3 bucket encryption to use the new KMS key (SSE-KMS). Update the S3 bucket policy to add a Deny effect and a Condition element of "StringNotEquals": { "s3:x-amz-server-side-encryption": "aws:kms" }.

Use Amazon Inspector to determine which S3 buckets contain sensitive data. Update the key policy on the AWS managed key to provide access to administrators only. Use AWS Batch to encrypt all existing objects that include sensitive data in the S3 buckets with the updated AWS managed key.

Use Amazon Made to determine which S3 buckets contain sensitive data. Create a new AWS KMS customer managed key and a key policy that provides access to administrators only. Set default S3 bucket encryption to use the new KMS key (SSE-KMS). Create an AWS Step Functionsworkflow to encrypt all existing S3 objects that include sensitive data by using the new KMS key.

Use Amazon Made to determine which S3 buckets contain sensitive data. Update the key policy on the AWS managed key to provide access to administrators only. Update the S3 bucket policy to add a Deny effect and a Condition element of "StringNotEquals": { "s3:x-amz-server-side-encryption": "aws:kms" }.

Answer:

Explanation:

The company does not have a data inventory and needs to identify which S3 buckets contain sensitive data. The appropriate AWS managed service for discovering and classifying sensitive data in S3 is Amazon Macie. Macie is designed to discover, classify, and report on sensitive data such as PII in S3 buckets. Amazon Inspector is primarily focused on vulnerability management for compute and container resources and does not provide S3 sensitive data classification in the way Macie does.

After identifying sensitive data locations, the company needs to ensure sensitive data is encrypted with a key that only administrators can access. SSE-S3 uses S3-managed keys and does not provide fine-grained administrative control of key usage in the same way as SSE-KMS with a customer managed key. Using AWS KMS customer managed keys allows the company to control access through key policies and IAM policies so that only designated administrator principals can use or manage the key.

The requirement also implies existing objects already encrypted with SSE-S3 need to be re-encrypted with SSE-KMS for sensitive objects. Changing default encryption only affects new objects. Existing objects must be rewritten (copied over themselves or copied to a new location) using SSE-KMS with the customer managed key. An orchestrated workflow is a common approach to iterate over identified objects and perform copy operations with the desired encryption settings.

Option C uses Macie for discovery, creates a KMS customer managed key restricted to administrators, sets bucket default encryption to SSE-KMS for future objects, and uses a Step Functions workflow to re-encrypt existing sensitive objects. This meets both the discovery requirement and the encryption/control requirement.

Option A is incorrect because Inspector is not the right service to inventory sensitive data in S3. Although the use of a customer managed KMS key and bucket policy enforcement is directionally correct for controlling encryption on writes, the first step (sensitive data discovery) is wrong.

Option B is incorrect because AWS managed keys cannot have their key policies modified by customers in the way customer managed keys can. Also, Inspector is not the right tool for sensitive data discovery in S3.

Option D is incorrect for the same reasons: it relies on Macie correctly for discovery but then attempts to modify an AWS managed key policy, which is not the correct method for restricting access. To restrict access, the company should use a KMS customer managed key with an appropriate key policy.

Therefore, using Amazon Macie plus an AWS KMS customer managed key and a workflow to re-encrypt existing sensitive objects is the correct solution.

[References:AWS documentation on Amazon Macie for discovering and classifying sensitive data in Amazon S3.AWS documentation on SSE-KMS with AWS KMS customer managed keys for encryption control and administrative access restrictions.AWS documentation and best practices describing that changing S3 default encryption affects new objects and that existing objects must be rewritten to change encryption settings., , , , ]

Question 179

Question 181

A company with global offices has a single 1 Gbps AWS Direct Connect connection to a single AWS Region. The company's on-premises network uses the connection to communicate with the company's resources in the AWS Cloud. The connection has a single private virtual interface that connects to a single VPC.

A solutions architect must implement a solution that adds a redundant Direct Connect connection in the same Region. The solution also must provide connectivity to other Regions through the same pair of Direct Connect connections as the company expands into other Regions.

Which solution meets these requirements?

Options:

Provision a Direct Connect gateway. Delete the existing private virtual interface from the existing connection. Create the second Direct Connect connection. Create a new private virtual interlace on each connection, and connect both private victual interfaces to the Direct Connect gateway. Connect the Direct Connect gateway to the single VPC.

Keep the existing private virtual interface. Create the second Direct Connect connection. Create a new private virtual interface on the new connection, and connect the new private virtual interface to the single VPC.

Keep the existing private virtual interface. Create the second Direct Connect connection. Create a new public virtual interface on the new connection, and connect the new public virtual interface to the single VPC.

Provision a transit gateway. Delete the existing private virtual interface from the existing connection. Create the second Direct Connect connection. Create a new private virtual interface on each connection, and connect both private virtual interfaces to the transit gateway. Associate the transit gateway with the single VPC.

Question 182

A company uses a Grafana data visualization solution that runs on a single Amazon EC2 instance to monitor the health of the company's AWS workloads. The company has invested time and effort to create dashboards that the company wants to preserve. The dashboards need to be highly available and cannot be down for longer than 10 minutes. The company needs to minimize ongoing maintenance.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Migrate to Amazon CloudWatch dashboards. Recreate the dashboards to match the existing Grafana dashboards. Use automatic dashboards where possible.

Create an Amazon Managed Grafana workspace. Configure a new Amazon CloudWatch data source. Export dashboards from the existing Grafana instance. Import the dashboards into the new workspace.

Create an AMI that has Grafana pre-installed. Store the existing dashboards in Amazon Elastic File System (Amazon EFS). Create an Auto Scaling group that uses the new AMI. Set the Auto Scaling group's minimum, desired, and maximum number of instances to one. Create an Application Load Balancer that serves at least two Availability Zones.

Configure AWS Backup to back up the EC2 instance that runs Grafana once each hour. Restore the EC2 instance from the most recent snapshot in an alternate Availability Zone when required.

Question 183

A company needs to optimize the cost of an AWS environment that contains multiple accounts in an organization in AWS Organizations. The company conducted cost optimization activities 3 years ago and purchased Amazon EC2 Standard Reserved Instances that recently expired.

The company needs EC2 instances for 3 more years. Additionally, the company has deployed a new serverless workload.

Which strategy will provide the company with the MOST cost savings?

Options:

Purchase the same Reserved Instances for an additional 3-year term with All Upfront payment. Purchase a 3-year Compute Savings Plan with All Upfrontpayment in the management account to cover any additional compute costs.

Purchase a I-year Compute Savings Plan with No Upfront payment in each member account. Use the Savings Plans recommendations in the AWS CostManagement console to choose the Compute Savings Plan.

Purchase a 3-year EC2 Instance Savings Plan with No Upfront payment in the management account to cover EC2 costs in each AWS Region. Purchase a 3-year Compute Savings Plan with No Upfront payment in the management account to cover any additional compute costs.

Purchase a 3-year EC2 Instance Savings Plan with All Upfront payment in each member account. Use the Savings Plans recommendations in the AWS CostManagement console to choose the EC2 Instance Savings Plan.

Answer:

Explanation:

The company should purchase the same Reserved Instances for an additional 3-year term with All Upfront payment. The company should purchase a 3-year Compute Savings Plan with All Upfront payment in the management account to cover any additional compute costs. This solution will provide the company with the most cost savings because Reserved Instances and Savings Plans are both pricing models that offer significant discounts compared to On-Demand pricing. Reserved Instances are commitments to use a specific instance type and size in a single Region for a one- or three-year term. You can choose between three payment options: No Upfront, Partial Upfront, or All Upfront. The more you pay upfront, the greater the discount1. Savings Plans are flexible pricing models that offer low prices on EC2 instances, Fargate, and Lambda usage, in exchange for a commitment to a consistent amount of usage (measured in $/hour) for a one- or three-year term. You can choose between two types of Savings Plans: Compute Savings Plans and EC2 Instance Savings Plans. Compute Savings Plans apply to any EC2 instance regardless of Region, instance family, operating system, or tenancy, including those that are part of EMR, ECS, or EKS clusters, or launched by Fargate or Lambda. EC2 Instance Savings Plans apply to a specific instance family within a Region and provide the most savings2. By purchasing the same Reserved Instances for an additional 3-year term with All Upfront payment, the company can lock in the lowest possible price for its EC2 instances that run continuously for 3 years. By purchasing a 3-year Compute Savings Plan with All Upfront payment in the management account, the company can benefit from additional discounts on any other compute usage across its member accounts.

The other options are not correct because:

Purchasing a 1-year Compute Savings Plan with No Upfront payment in each member account would not provide as much cost savings as purchasing a 3-year Compute Savings Plan with All Upfront payment in the management account. A 1-year term offers lower discounts than a 3-year term, and a No Upfront payment option offers lower discounts than an All Upfront payment option. Also, purchasing a Savings Plan in each member account would not allow the company to share the benefits of unused Savings Plan discounts across its organization.

Purchasing a 3-year EC2 Instance Savings Plan with No Upfront payment in the management account to cover EC2 costs in each AWS Region would not provide as much cost savings as purchasing Reserved Instances for an additional 3-year term with All Upfront payment. An EC2 Instance Savings Plan offers lower discounts than Reserved Instances for the same instance family and Region. Also, a No Upfront payment option offers lower discounts than an All Upfront payment option.

Purchasing a 3-year EC2 Instance Savings Plan with All Upfront payment in each member account would not provide as much flexibility or cost savings as purchasing a 3-year Compute Savings Plan with All Upfront payment in the management account. An EC2 Instance Savings Plan applies only to a specific instance family within a Region and does not cover Fargate or Lambda usage. Also, purchasing aSavings Plan in each member account would not allow the company to share the benefits of unused Savings Plan discounts across its organization.
