Oracle Cloud Infrastructure 2022 Architect Professional — Question 41

You are working as a solution architect with a global automotive provider who is looking to create a multi-cloud solution. They want to run their application tier in Microsoft Azure while utilizing the Oracle DB Systems in the Oracle Cloud Infrastructure (OCI).
What is the most-fault tolerant and secure solution for this customer?

Answer options

• A. Create an encrypted, Virtual Private Network connection between the Microsoft Azure Virtual Network that contains the application tier and the OCI Virtual Cloud Network (VCN) that contains the Oracle Databases.
• B. Create a FastConnect virtual circuit with Microsoft Azure as the provider to establish a private Interconnect between the application tier running in the Azure Virtual Network and the OCI VCN that contains the Oracle Databases.
• C. Use an OCI Virtual Cloud Network remote peering connection to create a remote network connection between the application tier running in Microsoft Azure Virtual Network and Oracle Databases running in the OCI Virtual Cloud Network (VCN).
• D. Deploy the Oracle database system into a public subnet in your VCN and assign a public IP address. Connect your application tier running in Azure to the public IP address of the database system over the internet.

Correct answer: B

Explanation

The correct answer is B because establishing a FastConnect virtual circuit provides a dedicated and private connection, ensuring both security and high availability for the application and database communication. Option A, while encrypted, may not offer the same level of performance and reliability as FastConnect. Option C does not create a private connection, which can introduce latency and potential security issues. Option D exposes the database to the internet, compromising security and making it less fault-tolerant.
