Your current Dataproc cluster operates within a single VPC (Virtual Private Cloud) network and is confined to a single subnet with an IP address range of 172.16.20.128/25. Notably, there are no private IP addresses left available within this VPC network. Given this situation, you need to add new virtual machines (VMs) that can communicate with your existing cluster. What steps should you take to achieve this with minimal effort?
Explanation:
The correct answer is A, which is to modify the existing subnet range to 172.16.20.0/24. This solution directly addresses the lack of available private IP addresses by expanding the existing subnet. The command 'gcloud compute networks subnets expand-ip-range' can be used to expand the IP range of a Compute Engine subnetwork, effectively increasing the number of available addresses. This approach requires the minimum amount of steps and avoids the complexity of creating new VPC networks and setting up VPC peering or custom route exchanges.
