What condition must be met before creating a FlexClone volume?

• A. The parent volume must be online and writable.
• B. The parent must contain at least one Snapshot copy.
• C. The aggregate must be in RAID-DP mode.
• D. The parent must be a FlexGroup volume.

Answer: (B)

FlexClone creation is snapshot-based. A new clone is created from a snapshot of the parent volume, so there must be at least one snapshot on the parent to serve as the source. The clone initially shares data blocks with that snapshot and uses copy-on-write as writes occur. If no snapshot exists, there’s no source to base the clone on, so the operation can’t proceed. The other factors listed—whether the parent is online and writable, the aggregate’s RAID-DP mode, or the parent being a FlexGroup—do not by themselves govern the ability to create a FlexClone.
