Question

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?

Options

  • AConfigure VPC peering in a full mesh.
  • BAlter the routing table to resolve the asymmetric route.
  • CCreate network tags to allow connectivity between all three VPCs.
  • DDelete the legacy network and recreate it to allow transitive peering.

Explanation

Only directly peered networks can communicate. Transitive peering is not supported. In other words, if VPC network N1 is peered with N2 and N3, but N2 and N3 are not directly connected, VPC network N2 cannot communicate with VPC network N3 over VPC Network Peering. https://cloud.google.com/vpc/docs/vpc-peering
