Google Cloud Associate Cloud Engineer — Question 106

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?

Answer options

• 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.

Correct answer: A

Explanation

The correct answer is A because creating an instance template with valid syntax and deleting any persistent disks with matching names ensures that new instances can be created without conflicts. Options B, C, and D involve additional steps or changes that are not necessary to resolve the instance creation failure promptly, making them less efficient solutions.
