CompTIA Cloud+ (CV0-002) — Question 177

An administrator needs to make a file-level backup of a VM before deploying monthly updates. The backup should capture all changes since the last backup but should NOT reset the archive bit on any files.
Which of the following backup types BEST meets these requirements?

Answer options

• A. Incremental
• B. Full
• C. Snapshot
• D. Differential
• E. Delta Tracking

Correct answer: D

Explanation

The differential backup type captures all changes made since the last full backup and does not reset the archive bit, which aligns perfectly with the administrator's requirements. In contrast, an incremental backup resets the archive bit, a full backup captures all data without regard to changes, a snapshot is typically used for point-in-time recovery, and delta tracking involves tracking changes but may not meet the specific file-level backup needs.
