Compute Engine across multiple locations stores multiple copies of snapshots.
How is the data integrity of the data ensured?

Answer options:

A.By making sure that the snapshot is created only when VM is not running
B.By automatic checksum
C.By making sure that the snapshot is created only when VM is running
D.By disabling incremental backup

Correct Answer: B
Option A is incorrect. Snapshot can be created from disks when attached to a running VM. Hence, this statement is incorrect.
Option B is correct. Snapshot data integrity is ensured by automatic checksum.
Option C is incorrect. Snapshot data integrity is ensured by automatic checksum. Hence, the state of the VM is not a concern.
Option D is incorrect. Snapshot data integrity is ensured by automatic checksum. Data is incrementally backed up from disks.
