AWS Certified Advanced Networking – Specialty ANS-C00 – Question168

Your company has a high-availability hybrid solution that utilizes a two Direct Connect connections and a backup VPN connection. For some reason, traffic is preferring the VPN connection instead of the direct connection. You have prepended a longer AS_PATH on the VPN connection, but AWS still prefers it over the Direct Connect connections.
What might you be able to do to fix this issue?

A.
Advertise a less specific prefix on the VPN.
B. Remove the prepended AS_PATH.
C. Reconfigure the VPN as a static VPN instead of dynamic.
D. Increase the MED on the VPN.

Correct Answer: A

Explanation:

Explanation: The only reason a VPN would be preferred over Direct Connect is if it has a more specific prefix. This was not discussed in the question but is assumed since it is the only criteria in the path selection process that supersedes Direct Connect.
