You have created a subnet named subnetace1 with 16,382 addresses using 192.168.0.0. Later you realize that you won't require too many addresses, and so you want to reduce addresses to
254. Which of the following command would you use?

• A.There is no command in google cloud to reduce the number of available addresses in a subnet.
• B.gcloud compute networks subnets expand-ip-range subnetace1 --prefix-length=-12
• C.gcloud compute networks subnets expand-ip-range subnetace1 --size=248
• D.gcloud compute networks subnets expand-ip-range subnetace1 --prefix-length=28

Your managed instance group raised an alert stating that new instance creation has failed to create new instances. You need to maintain the number of running instances specified by the template to be able to process expected application traffic. What should you do?

• A.Delete the current instance template and replace it with a new instance template. Verify that the instance name and persistent disk name values are not the same in the template. Set the disks.autoDelete property to true in the instance template.
• B.Verify that the instance template being used by the instance group contains valid syntax. Delete any persistent disks with the same name as instance names. Set the disks.autoDelete property to true in the instance template.
• C.Create an instance template that contains valid syntax which will be used by the instance group. Delete any persistent disks with the same name as instance names.
• D.Create an instance template that contains valid syntax that will be used by the instance group. Verify that the instance name and persistent disk name values are not the same in the template.
