Google Cloud Professional Cloud Network Engineer — Question 188

Your company deployed a hub and spoke architecture in Google Cloud to host their workloads. They use VPC network peerings to connect the hub and the spokes. You need to replicate the design and use Network Connectivity Center. What should you do?

Answer options

• A. Choose a Network Connectivity Center star topology. Deploy the hub VPC in the center group. Deploy the spoke VPCs in the edge group.
• B. Choose a Network Connectivity Center star topology. Deploy the spoke VPCs in the center group. Deploy the hub VPC in the edge group.
• C. Choose a Network Connectivity Center mesh topology. Configure the hub and the spokes as Network Connectivity Center spokes.
• D. Choose a Network Connectivity Center mesh topology. Configure the spokes as Network Connectivity Center spokes.

Correct answer: A

Explanation

The correct answer is A because in a star topology, the hub VPC should be at the center for optimal routing and management of the spoke VPCs. Option B incorrectly places the spoke VPCs in the center group, which would disrupt the intended architecture. Options C and D suggest using a mesh topology, which is not suitable for a hub and spoke design as it does not provide the centralized management that the star topology offers.
