What describes multiple LUN snapshots?

Answer options

• A. Captures multiple point-in-time data states. Snapshot data state is marked "unmodified" from its source when attached. Snapshot tree supports multiple simultaneous attaches.
• B. Captures multiple point-in-time data states. Snapshot data state is marked "unmodified" from its source when attached. Snapshot tree supports only one attach at a time.
• C. Captures multiple point-in-time data states. Snapshot data state is marked "modified" from its source when attached. Snapshot tree supports multiple simultaneous attaches.
• D. Captures multiple point-in-time data states. Snapshot data state is marked "modified" from its source when attached. Snapshot tree supports only one attach at a time.

Correct answer: D

Explanation

The correct answer is D because it accurately states that LUN snapshots capture multiple point-in-time data states and that the snapshot data state is marked 'modified' when attached, which aligns with the typical behavior of such snapshots. Options A and B incorrectly describe the data state as 'unmodified', while option C incorrectly states that the snapshot tree supports multiple simultaneous attaches, which is not true for the context of this question.
