Which ONTAP feature creates writable, space-efficient clones instantly from snapshots?

• A. SnapMirror
• B. SnapVault
• C. FlexClone Volume
• D. FlexGroup Volume

Answer: (C)

Writable, space-efficient clones created from a snapshot are provided by FlexClone. It creates a new volume that initially shares data blocks with the source snapshot, using copy-on-write. Because of this sharing, the clone appears immediately as a writable copy, but no extra space is used for unmodified data. Only when you write to the clone are new blocks allocated, keeping storage overhead low while giving you an independent, writable environment right away. While other features handle remote replication (SnapMirror), backups (SnapVault), or scalable volumes (FlexGroup), they don’t deliver the same instant, space-efficient writable clone capability from a snapshot as FlexClone.
