Oracle Cloud Infrastructure 2020 Architect Professional — Question 17

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? (Choose the best answer.)

Answer options

• A. 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.
• 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. 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.
• D. 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).

Correct answer: B

Explanation

Option B is correct as it provides a private connection through FastConnect, ensuring both security and reliability for data transfer between Azure and OCI. Option A is insecure due to the public IP exposure, while Option C, although secure, may not offer the same level of performance as a dedicated circuit. Option D, while functional, may not be the best choice compared to the direct advantages of using FastConnect as outlined in Option B.
