ANS-C01 Network Management and Operations Practice Question
Network Topology
A network engineer troubleshoots a VPN connection that shows 'available' state but traffic is not passing. The on-premises firewall logs show that the tunnel is established, but no traffic. The engineer checks the VPN configuration. Based on the exhibit, what is the MOST likely cause of the problem?
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
✓
The VPN is configured for BGP (StaticRoutesOnly: false), but only a static route is added.
The VPN connection has `StaticRoutesOnly` set to `false`, which indicates that dynamic routing (BGP) is expected for route propagation. However, the route shown is a static route, so the VPN will not use it, as BGP is required. Without a proper BGP session or a static route with `StaticRoutesOnly` set to `true`, traffic cannot pass through the VPN. Option A is incorrect because the VPN state is indeed 'available'. Option C is incorrect because the outside IP addresses are routable over the internet. Option D is incorrect because the inside IP addresses (tunnel interfaces) are present in the configuration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The VPN connection is not in 'available' state.
Why it's wrong here
The exhibit shows 'available' state.
- ✓
The VPN is configured for BGP (StaticRoutesOnly: false), but only a static route is added.
Why this is correct
With StaticRoutesOnly: false, BGP is required for route propagation; static routes are ignored.
- ✗
The outside IP addresses are not routable over the internet.
Why it's wrong here
The outside IP addresses are public and routable.
- ✗
The inside IP addresses for the tunnels are missing.
Why it's wrong here
The exhibit shows inside IP addresses.
