AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 195

When configuring Active/Passive HA on VPN tunnels, choose the two best ways to configure this. (Choose two.)

Answer options

• A. Keep both tunnels up.
• B. Configure AS_PATH prepending on one of the paths.
• C. Turn off one of the paths until you need it.
• D. Configure MED on one of the tunnels.

Correct answer: A, B

Explanation

The correct answer includes A and B because keeping both tunnels up ensures continuous availability, while AS_PATH prepending helps in load balancing and redundancy. Options C and D are less effective as turning off one path defeats the purpose of HA, and configuring MED may not provide the desired active/passive functionality for HA.
