問題文
An administrator needs a consistent recovery point across three volumes that belong to the same application. Which use of a protection group achieves that?
選択肢
- Take three volume snapshots one after another in a short script so that the timestamps of the three snapshots end up close enough.
- Add the application host to a protection group and rely on the host to flush its own buffers before each snapshot of the group runs.
- Put the three volumes in one protection group so a single snapshot of the group captures them at the same point with write order preserved.
- Create three protection groups with the same schedule so that each volume is captured by its own group at the same minute of the hour.
