Practice Test 2 | Google Cloud Certified Associate Cloud Engineer | Dumps | Mock Test
You created a snapshot schedule and attached it to a disk for automating backup of your VM. Few days later when you were looking at the snapshots you notice that the snapshot size is different for each and every snapshot. What can be the reason?
A. Snapshots are incremental/point-in-time copies of VM.
B. Raise a ticket with the Google support regarding the same.
C. It is just a UI bug which is not yet solved by Google.
D. Increase the timeout window so that disk is backed up properly.
Explanation:
Answer A
Option A is correct: Snapshots are incremental or point-in-time copies of disk which means that from second snapshot only changed blocks are copied and because of this each snapshot size is different.
Option B is incorrect: Raising a support ticket is of no use.
Option C is incorrect: It is not a UI bug. It shows the actual size of snapshot.
Option D is incorrect: There is no such option present within snapshot scheduler.
