Explanation

A fault domain is a grouping of hardware and infrastructure within an availability domain.

Fault domains provide anti-affinity: they let you distribute your instances so that the instances are not on the same physical hardware within a single availability domain.

To control the placement of your compute instances, bare metal DB system instances, or virtual machine DB system instances, you can optionally specify the fault domain for a new instance or instance pool at launch time.

Explanation

The fully-automated onboarding option for OracleDB for Azure is faster and more convenient than the guided account linking. Hence the option "Guided onboarding is simpler and faster than fully automated onboarding" is NOT TRUE.

When the automated configuration finishes, OracleDB for Azure is fully operational. The Azure user that completed onboarding can login and use the OracleDB for Azure portal to deploy and provision databases for use in their Azure environment. Hence the option "An Azure user who completes fully automated onboarding can log in to the OracleDB for Azure portal, but cannot de-ploy and provision databases" is NOT TRUE.

If you used the guided onboarding process, the user who completed onboarding can login to the OracleDB for Azure portal, but not really do anything there. Before users can do anything produc-tive using OracleDB for Azure, you must first complete configuration steps for each user or user group. Hence the option "An Azure user who completes guided onboarding cannot log in to the Or-acleDB for Azure portal" is NOT TRUE.

Now, let's look at the only option left which is "Fully automated onboarding requires more permis-sions to be granted than guided onboarding". This option is TRUE as the automated onboarding process requires that the Azure user onboarding to OracleDB for Azure have at least one of the fol-lowing admin roles: Application Administrator, Cloud Application Administrator, Privileged Role Administrator, or Global Administrator. Guided onboarding is provided for customers who do not want to grant OracleDB for Azure all the Azure permissions required for fully automated onboard-ing. Hence this is the correct answer.

Explanation

For cross-cloud networking between Oracle Cloud and Microsoft Azure, set up a connection be-tween a FastConnect circuit in Oracle Cloud and an ExpressRoute circuit in Microsoft Azure.

Explanation

HeatWave is an in-memory query accelerator developed for Oracle MySQL Database Service. It’s a massively parallel, hybrid, columnar, query-processing engine with state-of-art algorithms for distributed query processing which provide very high performance for queries.

Explanation

Azure users log into OracleDB for Azure using their Azure credentials, and OracleDB for Azure streams much of the day-to-day operational data from the OracleDB for Azure managed OCI data-bases to Azure Application Insights and Azure Log Analytics. Because of this, Azure developers spend most of their time in Azure.

In some instances, an OracleDB for Azure user must log into the OCI Console to perform specific tasks that aren’t enabled or available in OracleDB for Azure today. To make this process easier, Az-ure customers setup identity federation between the Azure and OCI tenancies. With this in place, authorized users use a single set of credentials, their Azure credentials, to log into Azure and OCI

Explanation

In the question, frontend is in Azure and backend is in OCI. And the keywords are SECURE and LOW LATENCY data transfer.

Use public internet connections to transfer data between Azure and OCI, encrypting the data in transit - INCORRECT as this option won't provide LOW LATENCY data transfer (as it is us-ing public internet).

Leverage a VPN Gateway to create an encrypted tunnel between Azure and OCI for secure data transfer - INCORRECT as Site-to-Site VPN Connection won't provide LOW LATENCY data transfer as the connection traverses through public internet.

Implement a hybrid cloud approach by integrating on-premises infrastructure with both Azure and OCI - INCORRECT as there is no mention of on-premises environment in the question. This option is irrelevant here.

Establish a dedicated, private connection between Azure and OCI using Azure ExpressRoute and Oracle FastConnect - CORRECT as it provides a direct Interconnect between OCI and Microsoft Azure which in turn provides <2ms latency for superior multicloud network performance.

Explanation

Oracle Database Service for Azure (OracleDB for Azure) is an Oracle managed service delivering Oracle Database services in Oracle Cloud Infrastructure (OCI) directly to Microsoft Azure custom-ers through the OCI Azure Interconnect (a capability available between the two cloud environments in regions located around the world).

OracleDB for Azure uses a service-based approach, and is an alternative to manually creating complex cross-cloud deployments using the Interconnect.

Explanation

Network security groups (NSGs) act as a virtual firewall for your compute instances .

An NSG consists of a set of ingress and egress security rules that apply only to a set of VNICs of your choice in a single VCN (for example: all the compute instances that act as web servers in the web tier of a multi-tier application in your VCN).

Hence, "Use Network Security Groups to apply specific firewall rules for each component." is the CORRECT answer.

In this question , you can straightaway reject "Use Virtual Cloud Networks to create isolated net-works for each component." and "Use Route Tables to define custom routing policies between each component." options.

NSG wins here due to the keywords "restrict communication between these components" in the question. A network security group (NSG) provides a virtual firewall for a set of cloud re-sources that all have the same security posture.

Explanation

With OCI multicloud's OracleDB for Azure, your database resources reside in an OCI account that is linked to your Azure account through Oracle Interconnect for Microsoft Azure, an Oracle-managed tunnel connection.

OracleDB for Azure configures DNS on both sides of the Interconnect to enable bi-directional communication between applications in the Azure tenancy and database resources in OracleDB for Azure.

Explanation

The keyword mentioned in the question is "However, they want to have full control over the Az-ure permissions that should be granted. "

The fully-automated onboarding option for OracleDB for Azure is faster and more convenient than the guided account linking, but some organizations may have security policies that do not allow them to grant the required permissions to the Oracle Database Service enterprise applica-tion that runs in their Azure account.

Guided onboarding is provided for customers who do not want to grant OracleDB for Azure all the Azure permissions required for fully automated onboarding.

The remaining two options - Auto pilot linking and Fully scripted configuration are INVALID. There doesn't exist anything like these in Oracle Database Service for Azure onboarding.

Hence the correct answer is Guided account linking

Explanation

Controlling Traffic Flow Over the Connection

Even if a connection has been established between your VCN and VNet, you can control the packet flow over the connection with route tables in your VCN. For example, you can restrict traf-fic to only specific subnets in the VNet.

Controlling the Specific Types of Traffic Allowed

It's important that you ensure that all outbound and inbound traffic with the VNet is intended or expected and well defined. Implement Azure network security group and Oracle security rules that explicitly state the types of traffic one cloud can send to the other and accept from the other.
