Which Data ONTAP Cluster-Mode clone technology will lock a Snapshot copy?

The correct answer is A. LUN Clone. In Data ONTAP Cluster-Mode, a LUN clone locks its backing Snapshot copy so that the Snapshot cannot be deleted while the clone is present.

Why each option

In Data ONTAP Cluster-Mode, a LUN clone locks its backing Snapshot copy so that the Snapshot cannot be deleted while the clone is present.

ALUN CloneCorrect

When a LUN clone is created, ONTAP anchors it to a specific Snapshot copy and places a lock on that Snapshot, preventing manual or automatic deletion for the lifetime of the clone. This lock ensures the shared block data the clone references remains intact, preserving the clone's ability to function as a space-efficient, writable copy of the original LUN.

BSnapshot Clone

'Snapshot Clone' is not a recognized clone technology in Data ONTAP Cluster-Mode; Snapshots are point-in-time read-only copies, not a source object for a clone operation of this type.

CVolume Clone

FlexClone volumes reference a parent Snapshot but the explicit Snapshot locking behavior described in this exam objective is specifically associated with LUN clone operations, not volume-level FlexClones.

DAggr Clone

Aggregate-level cloning ('Aggr Clone') does not exist as a supported technology in Data ONTAP Cluster-Mode.
