Which LUN command creates a snapshot of a LUN?

• A. lun clone
• B. lun copy
• C. lun move
• D. lun snap

Answer: (D)

LUN snapshots are a point-in-time, space-efficient image of a LUN used for quick restore or testing. The command to create this LUN-level snapshot is the LUN snapshot command (lun snap). It doesn’t copy data or relocate the LUN; instead, it records a reference to the current state of the LUN so you can revert or clone from that exact moment later. The other operations serve different purposes: cloning creates a separate, writable copy derived from the original, copying duplicates data to another LUN, and moving relocates the LUN to a different location. None of these produce a LUN-level snapshot.
