GCP ACE · Question 29 · Domain 3.5: Deploying and implementing networking resources

You are creating a custom VPC network. You need to create a subnet in the us-west1 region with a CIDR range of 10.0.1.0/24. What is the correct approach?

Answer options:

A.

Create the VPC in auto mode, which automatically creates this specific subnet.

B.

Create the VPC in custom mode, then manually add the subnet specifying the region and CIDR range.

C.

Create a global subnet and assign it to the us-west1 region.

D.

Use Cloud Router to automatically provision the subnet.

How to approach this question

Understand the difference between auto mode and custom mode VPCs.

Full Answer

B.Create the VPC in custom mode, then manually add the subnet specifying the region and CIDR range.✓ Correct
Create the VPC in custom mode, then manually add the subnet specifying the region and CIDR range.
When you create a VPC network in custom mode, no subnets are created automatically. This gives you complete control over the IP address ranges and regions. You must manually create the subnet, specifying the `us-west1` region and the `10.0.1.0/24` CIDR block.

Common mistakes

Assuming auto mode allows you to specify custom IP ranges.
