Oracle Cloud Infrastructure 2021 Multicloud Architect Associate — Question 36

You have ordered two FastConnect connections that provide a high availability connection architecture between your on-premises data center and Oracle Cloud
Infrastructure (OCI). You want to run these connections in an ACTIVE/PASSIVE architecture.
How can you accomplish this? (Choose the best answer.)

Answer options

• A. Decrease the prefix length of AS for the FastConnect you want to use as PASSIVE connection.
• B. Enable BGP on the FastConnect that you want as the ACTIVE connection.
• C. Use AS PATH prepending with your routes.
• D. Adjust one of the connections to have a higher ASN.

Correct answer: C

Explanation

The correct answer is C, as AS PATH prepending helps prioritize routes, making one connection preferred over the other in an ACTIVE/PASSIVE setup. Option A is incorrect because decreasing the prefix length does not effectively designate an ACTIVE or PASSIVE connection. Option B is not the best choice as enabling BGP on the ACTIVE connection alone does not ensure the desired architecture. Option D does not influence the ACTIVE/PASSIVE configuration in the intended manner.
