Google Cloud Professional Cloud Network Engineer PCNE — Topic 1 Question 194

Question

Your company's current network architecture has two VPCs that are connected by a dual-NIC instance that acts as a bump-in-the-wire firewall between the two VPCs. Flows between pairs of subnets across the two VPCs are working correctly. Suddenly, you receive an alert that none of the flows between the two VPCs are working anymore. You need to troubleshoot the problem. What should you do? (Choose two.)

Accepted Answer

Correct answer: B, D. The correct answer is B, D. Option B: Use Cloud Logging to verify that there were no modifications to the VPC firewall rules or policies that were applied to the two network interfaces of the dual-NIC instance. Option D: Verify that the dual-NIC instance has the --can-Ip-Forward attribute enabled. A VPC provides a global, software-defined private network for your Google Cloud resources. Cloud Logging centralizes, stores, and analyzes logs across services.
