Google Cloud Professional Cloud Network Engineer — Question 141

You configured Cloud VPN with dynamic routing via Border Gateway Protocol (BGP). You added a custom route to advertise a network that is reachable over the VPN tunnel. However, the on-premises clients still cannot reach the network over the VPN tunnel. You need to examine the logs in Cloud Logging to confirm that the appropriate routers are being advertised over the VPN tunnel. Which filter should you use in Cloud Logging to examine the logs?

Answer options

• A. resource.type= “gce_router”
• B. resource.type= “gce_network_region”
• C. resource.type= “vpn_tunnel”
• D. resource.type= “vpn_gateway”

Correct answer: A

Explanation

The correct answer is A because filtering by 'gce_router' allows you to see logs related to the routers involved in the BGP dynamic routing, which is crucial for verifying the advertisement of routes. The other options do not specifically target router logs, making them less relevant for this particular verification task.
