ANS-C01 Network Design Practice Question
Network Topology
Refer to the exhibit. A VPN connection has two tunnels. Which statement is correct about this VPN configuration?
⚠ Common exam trap
AWS often tests the misconception that two tunnels in a VPN connection are for load balancing, but in AWS Site-to-Site VPN, they are strictly for high availability (active/standby or active/active with BGP), not for aggregating bandwidth.

Correct answer & explanation
✓
The VPN provides high availability with two tunnels
The exhibit shows a VPN connection with two tunnels, which is the standard design for AWS Site-to-Site VPN to provide high availability. Each tunnel is on a separate device and path, so if one tunnel fails, traffic automatically fails over to the other tunnel. This ensures that the VPN connection remains operational even during maintenance or failure of a single tunnel.
