ANS-C01 Network Implementation Practice Question
A company is setting up AWS Site-to-Site VPN for connectivity between its on-premises network and AWS VPC. They want to ensure the VPN tunnel is highly available. Which THREE components should be configured? (Choose THREE.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
BGP dynamic routing over the VPN tunnels
Options B, D, and E are correct. BGP dynamic routing enables automatic failover between VPN tunnels, ensuring high availability. Two VPN tunnels per VPN connection provide redundant paths in case one tunnel fails. A second customer gateway device on-premises eliminates the single point of failure at the on-premises side. Option A is incorrect because a single tunnel does not provide redundancy. Option C is incorrect because static routing does not support automatic failover like BGP does.
