LPIC-3 Exam 304 (Virtualization and High Availability) — Question 4

When used with KVM, which of the following block device image formats support snapshots?

Answer options

• A. qcow
• B. dmg
• C. qed
• D. qcow2
• E. raw

Correct answer: D

Explanation

The correct answer is qcow2, as it offers advanced features like snapshots and dynamic allocation. While qcow also supports some features, it lacks the full capabilities of qcow2. The dmg, qed, and raw formats do not support snapshots in the same way, making them less suitable for this purpose.
