問題文
An administrator destroys several old snapshots on the source array to reclaim space and is surprised that the corresponding copies are still listed on the remote array. What explains the behavior?
選択肢
- The copies cannot be removed from the remote array at all because incoming replicas are always immutable once they have landed.
- The copies remain because destroy on the source only marks the snapshot and the removal is forwarded when the source timer expires.
- The copies are cached on the remote array for a short grace period and then removed as soon as the next transfer of the group completes.
- The copies on the remote array are governed by the retention of the target so they stay until it expires or they are destroyed there.
