Google Cloud Professional Cloud Network Engineer — Question 36

You need to establish network connectivity between three Virtual Private Cloud networks, Sales, Marketing, and Finance, so that users can access resources in all three VPCs. You configure VPC peering between the Sales VPC and the Finance VPC. You also configure VPC peering between the Marketing VPC and the
Finance VPC. After you complete the configuration, some users cannot connect to resources in the Sales VPC and the Marketing VPC. You want to resolve the problem.
What should you do?

Answer options

• A. Configure VPC peering in a full mesh.
• B. Alter the routing table to resolve the asymmetric route.
• C. Create network tags to allow connectivity between all three VPCs.
• D. Delete the legacy network and recreate it to allow transitive peering.

Correct answer: A

Explanation

The correct answer is A because configuring VPC peering in a full mesh allows all VPCs to communicate with each other directly. The other options do not address the fundamental issue of inter-VPC connectivity; altering the routing table (B) or creating network tags (C) do not resolve the lack of direct peering between Sales and Marketing, and deleting the legacy network (D) does not inherently solve the peering problem either.
