問題文

A file server was hit by a bad change in the early afternoon, and the operator has to bring it back to a usable state. Several recovery points from that same day are listed. Which point should be chosen?

選択肢

1. The operator should choose point copied remotely, because a recovery has to start from a point that was written before external copy reached the protected system.
2. The operator should choose point stored latest, because a recovery has to start from a point that was written before later capture reached the protected system.
3. The operator should choose point stored earlier, because a recovery has to start from a point that was written before faulty change reached the protected system.
4. The operator should choose point held longest, because a recovery has to start from a point that was written before removal limit reached the protected system.
