Explanation

Controlling the Establishment of a Connection

With Oracle Cloud Infrastructure IAM policies, you can control:

Who in your organization has the authority to create a FastConnect virtual circuit.

Who can manage route tables, network security groups, and security lists.

Oracle and Microsoft have created a cross-cloud connection between Oracle Cloud Infrastructure and Microsoft Azure in certain regions. So, the option "To control the location of the cross-cloud connection" has nothing to do with IAM policies and hence is INCORRECT.

The option "To control the type of traffic allowed between the Azure VNet and the OCI VCN" is also INCORRECT as you use Security Lists/Network Security Group to filter traffic and not IAM policies.

IAM policies also have no role to play in determining the bandwidth of the connection.

Explanation

As per the question, the keywords are "The enterprise wants to set up a private, secure, and isolat-ed network connection between the two clouds"

Use public internet to establish connectivity between the Microsoft Azure VNet and the OCI VCN - INCORRECT as this option won't provide private, secure and isolated connection.

Use Azure VPN and Oracle FastConnect to establish a private and secure tunnel between the Azure VNet and the OCI VCN is INCORRECT as it won't provide a isolated connection.

Use Azure Private Link to create a private connection between the workload and the database is INCORRECT as Azure Private Link enables you to access Azure PaaS Services (for example, Azure Storage and SQL Database) and Azure hosted customer-owned/partner services over a pri-vate endpoint in your virtual network.

Use Azure ExpressRoute and Oracle FastConnect to create a private interconnection between the Azure VNet and the OCI VCN. is CORRECT. To create an integrated multi-cloud experience, Microsoft and Oracle offer direct interconnection between Azure and Oracle Cloud Infrastructure (OCI) through ExpressRoute and FastConnect. Through the ExpressRoute and FastConnect inter-connection, customers can experience low latency, high throughput, private direct connectivity be-tween the two clouds.

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

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

The automated onboarding process requires that the Azure user onboarding to OracleDB for Az-ure have at least one of the following admin roles:

Application Administrator, Cloud Application Administrator, Privileged Role Administrator, or Global Administrator.

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 same way you do in Azure today. Each database resource created by Oracle Database Service for Azure gets an Azure connection string you can use to connect to the database from any Azure application.

During onboarding, Oracle Database Service for Azure creates network connections between the cloud environments.

During database provisioning, Oracle Database Service for Azure defines the DNS entries and connection strings needed to access the resource from Azure.

Azure developers (and applications) don’t need to know anything about Oracle Database Service for Azure—all they need is the connection string. Oracle publishes the connection string on the custom dashboard it creates for the database in Azure, so developers don’t have to leave the Azure portal to get what they need to access the database from their applications.

Hence, the CORRECT ANSWER is "By connecting to the Oracle databases using connection strings"

Explanation

Log Analytics Workspace, Application Insights and Custom Dashboard are Azure resources and hence we can eliminate these options.

We are left with Oracle Database Service which is the CORRECT answer.

Explanation

Site-to-Site VPN provides a site-to-site IPSec connection between your on-premises network and your virtual cloud network (VCN). The IPSec protocol suite encrypts IP traffic before the packets are transferred from the source to the destination and decrypts the traffic when it arrives.
