Which statement about FlexClone technology is true?

Which statement about FlexClone technology is true?

• A. FlexClone volumes are not writable.
• B. FlexClone volumes are created from a Snapshot copy.
• C. Deleting a parent volume automatically deletes all its clones.
• D. FlexClone LUNs share blocks with their parent until a write occurs.

Answer: (B)

FlexClone starts from a Snapshot, not from the live data alone. When you create a FlexClone, you specify a parent and a point-in-time Snapshot, and the clone is created from that Snapshot copy. The clone is writable from the start, but it shares data blocks with the Snapshot/parent and uses copy-on-write: no data is duplicated upfront, and only when a write occurs is new space allocated for the clone. This Snapshot-based origin is what makes FlexClone fast to create and space-efficient, which is precisely why this statement is the correct description.
