Google Cloud Associate Cloud Engineer — Question 238

Your Dataproc cluster runs in a single Virtual Private Cloud (VPC) network in a single subnetwork with range 172.16.20.128/25. There are no private IP addresses available in the subnetwork. You want to add new VMs to communicate with your cluster using the minimum number of steps. What should you do?

Answer options

• A. Modify the existing subnet range to 172.16.20.0/24.
• B. Create a new Secondary IP Range in the VPC and configure the VMs to use that range.
• C. Create a new VPC network for the VMs. Enable VPC Peering between the VMs'VPC network and the Dataproc cluster VPC network.
• D. Create a new VPC network for the VMs with a subnet of 172.32.0.0/16. Enable VPC network Peering between the Dataproc VPC network and the VMs VPC network. Configure a custom Route exchange.

Correct answer: A

Explanation

The correct answer is A because modifying the subnet range to 172.16.20.0/24 will provide additional IP addresses within the same subnetwork, allowing new VMs to be added easily. Options B, C, and D involve creating new IP ranges or networks, which would require more steps and configurations compared to simply adjusting the existing subnet range.
