In clustered Data ONTAP 8.2, which of the following commands will restore an entire volume

'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.

The 'volume snapshot restore' command performs a full volume revert, rolling back all data in the volume to the exact point-in-time state captured by the specified snapshot. This operation affects every file and directory in the volume and is destructive to any data written after the snapshot was taken.

'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.

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.
