Question

Your team is building a new application that will run on Compute Engine VMs in the us-east1 region. Company policy requires that you avoid the automatically created default subnets and instead control the exact IP address range used. You need to create a VPC network and a single subnet with the CIDR range 10.20.0.0/20 in us-east1. Which approach should you take?

Accepted Answer

Create a VPC network in custom mode, then create a subnet in us-east1 with the primary IP range 10.20.0.0/20.

Answer

Create a VPC network in auto mode, then delete all subnets except the one in us-east1 and edit its range to 10.20.0.0/20.

Answer

Create a VPC network in auto mode, which will automatically assign the 10.20.0.0/20 range to the us-east1 subnet.

Answer

Create a VPC network in custom mode, which automatically provisions a subnet in every region using ranges you define per project.
