問題文
Backup snapshots on the platform are kept in an immutable state, and the original is never mounted or exposed to a system outside the platform. A team needs a writable copy of one snapshot for a restore test. What does the platform do to satisfy that?
選択肢
- It mounts the original in a writable mode for the length of the test, so the writes are discarded at the point where the session against the cluster is closed.
- It converts the original into a writable snapshot and marks it, so the platform restores the immutable state once the retention of the test has expired.
- It copies the original into a staging area of the cluster first, so the test consumes an amount of storage equal to the size of the snapshot being examined.
- It creates a clone of the original at no additional storage, so the test writes into the clone while the snapshot it was made from stays exactly as it was.
