AWS Certified Advanced Networking – Specialty ANS-C00 – Question188

You are configuring multiple Direct Connect links for your organization and need them to be in an HA Active/Passive configuration with extreme sensitivity to outages in order to encourage very quick failover times. You also need to be able to control which link is active.
What two configuration changes should you implement? (Choose two.)

A.
MPLS
B. BFD
C. AS_PATH Prepending
D. BGP

Correct Answer: BC

Explanation:

Explanation: Bidirectional-Forwarding Detection will allow for faster failover times. AS_PATH Prepending will allow you to choose the default path. BGP is already implemented and MPLS does not matter.
