Explanation
PowerProtect Data Manager takes an automatic snapshot before beginning any upgrade, so if the upgrade fails or aborts mid-process, the system automatically rolls back to that snapshot, restoring the previous working state without manual intervention. Option A is wrong because a full reinstall is unnecessary - the rollback handles recovery automatically. Option C is incorrect and describes a nonsensical destructive behavior that no enterprise product would implement. Option D is wrong because the system does not remain in a broken state requiring support; the snapshot mechanism exists precisely to avoid that scenario.
Memory tip: Think of the snapshot as a "save point" in a video game - if the upgrade "boss fight" fails, you automatically respawn at your last save rather than starting over or being stuck dead.
