CompTIA Network+ (N10-007) — Question 521

A network technician sets up a new schedule on the backup server. Management has informed the technician that a full backup does not need to be completed every day. The technician sets up weekly full backups. Which of the following should the technician configure for the remaining days to MINIMIZE the daily backup size?

Answer options

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

Correct answer: B

Explanation

The technician should configure incremental backups for the remaining days, as they only save changes made since the last backup, thus minimizing the size of each daily backup. Snapshots capture the state of the system at a specific point, replicas create identical copies, and differential backups save changes since the last full backup, which are larger than incremental backups.
