A snapshot is a frozen, read-only image of the entire Data ONTAP active file system that reflects the state of the ____________ at the time the snapshot was created.

Qtrees are subdirectory partitions within a volume used for quota management; snapshots are not scoped to qtrees but to the entire containing volume.

In Data ONTAP, snapshots are volume-level operations - they record the state of the entire active file system within that volume at the moment the snapshot is taken, and can be used to restore individual files or the complete volume to that prior state.

A directory is a single folder within the file system hierarchy; Data ONTAP snapshots operate at the volume level and capture all directories within the volume, not a single directory.

A storage system contains all aggregates, volumes, and associated data; snapshots are scoped to individual volumes, not to the entire storage system.
