Selected Answer: A

I would use A & B to troubleshoot the issue. A test the connections between GCP and on-prem but to determine where the traffic is being dropped, you can visualize it via Network Topology and use the replay button would really be helpful. I still prefer A since this can further check and give you more details about the issue in your network and not just visualize its Topology

btw, there is no reply option in Network Intelligence Center Network Topology. You can just refresh and check the current traffic flow. Which is why for more detailed troubleshooting, use A
