CompTIA Network+ (N10-007) — Question 485

Which of the following backup techniques is used to capture all the data that has changed since the last full backup?

Answer options

• A. Incremental
• B. Replica
• C. Differential
• D. Snapshot

Correct answer: C

Explanation

The correct answer is C, Differential, as it backs up all changes made since the last full backup, allowing for a complete restoration of data. Option A, Incremental, only backs up changes made since the last backup of any type, which can lead to more restore points. Options B and D, Replica and Snapshot, do not specifically relate to capturing changes since a full backup.
