Practice Test 2 | Google Cloud Certified Associate Cloud Engineer | Dumps | Mock Test
Your company is running a tightly coupled application on Google Cloud VM instances, storing each and every data on disks and auto scaling is not possible. Black Friday sale is approaching and your company has provisioned enough number of additional servers and ample amount of disk space to cater the demand but suddenly during the sale you notice that on one of the server disk space is about to hit 90% usage and your manager has asked you to add 200GB immediately.
While upgrading the disk in hurry you accidently increased the size to 2000GB instead of 200GB and your manager is yelling at you to downgrade the disk. You are trying to downgrade the disk but are unable to do so. What can be the reason?
A. You need to stop the VM and downgrade the disk.
B. You can only upgrade the disk.
C. Downgrading the disk is only possible via CLI/API.
D. None of the above.
Explanation:
The correct answer is Option B.
Option B is correct: Disks can only be upgraded in terms of size.
Option A is incorrect: As downgrading the disk is not supported stopping the instance is of no help.
Option C is incorrect: Downgrading the disk is not even possible via CLI/API.
Option D is incorrect: Because correct answer is option B, this is an invalid choice.
