Question
In clustered Data ONTAP 8.2, which of the following commands will restore an entire volume
Options
- Avolume snapshot promote
- Bvolume snapshot restore
- Cvolume snapshot resync
- DNone of the above, just use the .snapshot or ~snapshot directory to restore the entire volume
Explanation
In clustered Data ONTAP 8.2, the 'volume snapshot restore' command is used to revert an entire volume to a specific snapshot state.
Common mistakes.
- A. 'volume snapshot promote' is not a valid clustered Data ONTAP command for full volume restore; snapshot promotion applies to FlexClone split operations, not point-in-time volume recovery.
- C. 'volume snapshot resync' is not a standard restore command; resync is associated with re-establishing SnapMirror relationships after a break, not snapshot-based volume recovery.
- D. The .snapshot or ~snapshot directory enables restore of individual files and folders but cannot revert the entire volume to a previous state - that requires the CLI command.
