Which of the following is true while creating a boot persistent disk from a snapshot?

Question

Options

• AYou cannot apply a snapshot to an existing persistent disk, or apply a snapshot to persistent
• BIt is only possible to apply data from a snapshot when you first create a persistent disk.
• CAfter you create a snapshot of a boot persistent disk, you can apply data from that snapshot to
• DAll of the above.

• B
  2% (1)
• C
  4% (2)
• D
  94% (47)

Explanation

All three statements are true and consistent. (A) and (B) both state the same constraint: you cannot apply snapshot data to an already-existing persistent disk - the snapshot data can only be used at disk creation time. (C) correctly states that after taking a snapshot of a boot persistent disk, you can apply that snapshot's data when creating a new persistent disk (for example, to restore a system or spin up a clone). These three statements together fully describe GCP's snapshot behavior for persistent disks: snapshots are point-in-time copies used exclusively during new disk creation, not for patching existing disks. 'All of the above' (D) is therefore correct.
