Answer: 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.
Option A is the correct answer because you cannot update or delete an existing instance template if it is in use. Therefore, you need to create a new instance template with valid syntax and delete any persistent disks that have the same names as the instances. This approach ensures that the managed instance group can create new instances as needed.

Your managed instance group has triggered an alert indicating that the creation of new instances has failed. This failure impacts the ability to maintain the desired number of running instances as specified in the instance template, which is crucial for handling the anticipated application traffic. What steps should you take to resolve this issue and ensure the necessary capacity is met?
A
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.
B
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.
C
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.
D
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.
