問題文
A protection group replicates every ten minutes and the replication lag reported on the source array has been sitting at about four minutes all week. An auditor asks what the worst case data loss would be if the source site were destroyed right now. How should that be described?
選択肢
- Roughly the schedule interval added to the current lag because the newest transferred copy is already that far behind the source.
- Exactly the schedule interval because the replication engine always completes a transfer before the next scheduled snapshot begins.
- Only the current lag because every write is forwarded as it happens and the schedule merely controls how long copies are kept.
- Nothing at all because the target array holds a synchronous mirror as soon as the protection group has a replication target defined.
