Network Visualizer is the tool that provides a diagram of the implemented topology of all VCNs in a selected region and tenancy. Network Visualizer is a feature of the OCI Networking service that allows users to view and manage their network resources in a graphical interface. It can help users understand their network topology, troubleshoot issues, and optimize performance. The other options are not tools that provide a diagram of the VCN topology, but rather other features or services of OCI Networking. References: [Network Visualizer]

Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges. The explanation is that a VCN CIDR prefix is the range of IPv4 addresses that can be used within the VCN and its subnets. The VCN CIDR prefix should not overlap with other VCNs in your tenancy or with your organization’s private IP network ranges, as this can cause routing conflicts and connectivity issues. You should choose a VCN CIDR prefix that is large enough to accommodate your current and future needs, but not too large to waste IP addresses. You can use any of the private IPv4 address ranges specified in RFC 1918 for your VCN CIDR prefix.

Allow group A-Developers to create volumes in compartment Project-A is an invalid IAM policy. This is because create is not a valid verb for volumes. The correct verb for creating volumes is attach. The other options are valid IAM policies that use correct verbs and syntax. References: [IAM Policies], [Verbs]

Live Migration Agent is not a valid Oracle Cloud Agent plugin name. Oracle Cloud Agent plugins are the following1:

• Bastion: Allows secure shell (SSH) connections to an instance without public IP addresses using the Bastion service.
• Block Volume Management: Configures Block Volume sessions for the instance.
• Compute Instance Monitoring: Emits metrics about the instance’s health, capacity, and performance. These metrics are consumed by the Monitoring service.
• Compute Instance Run Command: Runs scripts within the instance to remotely configure, manage, and troubleshoot the instance.
• Custom Logs Monitoring: Ingests custom logs into the Logging service.
• Management Agent: Collects data from resources such as OSs, applications, and infrastructure resources for Oracle Cloud Infrastructure services that are integrated with Management Agent.
• OS Management Service Agent: Enables you to manage updates and patches for the operating system running on your instance.

Live Migration is a feature of Oracle Cloud Infrastructure that enables you to migrate a running instance from one physical host to another without rebooting the instance or impacting its availability. Live Migration does not require any Oracle Cloud Agent plugin to function.

According to the Oracle Cloud Guard documentation1, Cloud Guard is a cloud native service that helps customers monitor, identify, achieve, and maintain a strong security posture on Oracle Cloud. Use the service to examine your Oracle Cloud Infrastructure resources for security weakness related to configuration, and your Oracle Cloud Infrastructure operators and users for risky activities. Upon detection, Cloud Guard can suggest, assist, or take corrective actions, based on your configuration.

Therefore, option A and option E are correct ways that Cloud Guard helps improve the overall security posture for your tenancy. Option B is incorrect because Cloud Guard does not allow you to centrally manage encryption keys. That is the function of the Vault service2. Option C is incorrect because Cloud Guard does not prevent you from creating misconfigurations on your resources in OCI. It only detects and reports them, and optionally takes corrective actions. Option D is incorrect because Cloud Guard does not mask sensitive data and monitor security controls on your Oracle databases. That is the function of the Data Safe service3.

 Creating and managing records, creating and managing zones, and viewing all zones are three capabilities that are available with the OCI DNS service. Records are data elements that map domain names to IP addresses or other information. Zones are collections of records that correspond to a domain name or a subdomain name. The OCI DNS service allows users to create and manage records and zones for their domains or subdomains, as well as view all zones in their tenancy. The other options are not capabilities of the OCI DNS service, but of other OCI services such as WAF, IAM, and Networking. References: [DNS Service], [Records], [Zones]

Create a replication policy to send data to a different bucket in another OCI region. The explanation is that replication is a feature of Object Storage that allows you to automatically copy objects from one bucket to another bucket, either in the same region or in a different region. Replication can help you improve data availability and durability, as well as meet compliance and disaster recovery requirements. To enable replication, you need to create a replication policy that specifies the source and destination buckets, the replication frequency, and the replication filters. Replication policies are evaluated every five minutes and copy any new or updated objects from the source bucket to the destination bucket.

Interval is the field that provides the time window for aggregating metric data points plotted on the metric chart. Interval is a parameter that specifies how often metric data points are collected and aggregated by the Monitoring service. For example, an interval of 5 minutes means that metric data points are aggregated every 5 minutes and displayed on the chart. The other options are not fields that provide the time window for aggregating metric data points, but rather other parameters that define the metric query. References: [Interval]

Internet Gateway, NAT Gateway, and Service Gateway are three gateways that are created automatically when creating a VCN with the VCN wizard. An Internet Gateway allows public traffic between the VCN and the internet. A NAT Gateway allows private traffic from the VCN to access the internet without exposing the VCN resources to incoming internet connections. A Service Gateway allows private traffic from the VCN to access OCI services such as Object Storage, Email Delivery, and Notifications. The other options are not created automatically by the VCN wizard, but can be added manually later if needed. References: [VCN Wizard], [Gateways]

Dimensions and Grouping Function are two optional components while creating the Monitoring Query Language (MQL) expressions in the OCI Monitoring service. Dimensions are key-value pairs that provide additional information about a metric, such as region, compartment, or resource type. Grouping Function is a function that aggregates metric data across one or more dimensions, such as sum, count, or average. The other options are required components for MQL expressions. References: [Dimensions], [Grouping Function]

Oracle Security Zones is a service that helps you enforce best practices and prevent misconfigurations on your OCI resources by applying predefined policies and controls. Some of the benefits of using Security Zones are:

• Encrypt storage resources with a customer-managed key: Security Zones require that all storage resources, such as block volumes, boot volumes, file systems, and object storage buckets, are encrypted with a customer-managed key from Vault. This ensures that you have full control over the encryption and decryption of your data at rest.
• Deny public access to OCI resources, such as databases and object storage buckets: Security Zones prevent you from creating or updating OCI resources that have public access enabled, such as databases and object storage buckets that are accessible from the internet. This reduces the risk of unauthorized access or data leakage.

The explanation is that shielded instances are VM instances that have additional security features to protect them from low-level threats, such as rootkits and bootkits that can infect the firmware and operating system and are difficult to detect. Shielded instances use verified boot, which ensures that only trusted software components are executed during the boot process. Shielded instances also use virtual trusted platform module (vTPM), which provides a secure storage for encryption keys and certificates. Shielded instances are available for Oracle Linux 8 platform images with VM.Standard2.* shapes.

 From the version 1 menu on the OCI console, select “Promote to Current”. The explanation is that when you promote a secret version to current, it becomes the latest version of the secret and is used by default when you access the secret. This way, you can rollback to a previous version of the secret without creating a new version.

The explanation is that burstable instances are VM instances that have a baseline utilization of either 12% or 50% of each CPU core, not 25% or 75%. Burstable instances are designed for scenarios where an instance is typically idle or has low CPU utilization but occasionally needs to burst above the baseline to handle spikes in demand. Burstable instances cost less than regular instances with the same total OCPU count but charge extra for bursting above the baseline OCPU.
