Which two clustered Data ONTAP clone technologies will lock volume snapshot? (Choose two)
The correct answer is B. LUN Clone D. FlexClone. In clustered Data ONTAP, both FlexClone and LUN Clone operations lock the parent volume snapshot that serves as their backing baseline.

Why each option
In clustered Data ONTAP, both FlexClone and LUN Clone operations lock the parent volume snapshot that serves as their backing baseline.
Vol Clone is not a recognized Data ONTAP clone technology and does not correspond to any feature that locks a volume snapshot.
A LUN Clone is created from a specific volume snapshot, and that snapshot is locked and cannot be deleted as long as the LUN Clone exists, because the clone depends on it for its data blocks.
AggrClone is not a valid Data ONTAP clone technology and has no relationship to snapshot locking behavior.
FlexClone creates a space-efficient writable clone of a volume by referencing a parent snapshot; that snapshot is locked and protected from deletion until all FlexClone volumes derived from it are destroyed or split.
SnapClone is not a standard Data ONTAP clone technology and does not represent a feature that locks volume snapshots.
