GCP ACE · Question 39 · Domain 4.5: Managing networking resources
You have a custom-mode VPC with a subnet in 'us-west1' using the CIDR range 10.0.0.0/24. You are running out of IP addresses in this subnet and need to expand it to 10.0.0.0/20.
What is the impact of running the gcloud compute networks subnets expand-ip-range command?
Answer options:
All VMs in the subnet will be rebooted to receive new IP addresses.
The subnet is expanded immediately without any downtime for existing VMs.
You must delete and recreate the subnet with the new CIDR range.
The operation will fail because you cannot change a /24 to a /20.
