CompTIA A+ Core 2 (220-1102) — Question 588

A user wants to back up a device's OS and data. Which of the following is the best way to accomplish this task?

Answer options

• A. Incremental backup
• B. System image
• C. System restore point
• D. Differential backup

Correct answer: B

Explanation

The best option for backing up an entire operating system along with its data is a System image, as it creates a complete snapshot of the system. Incremental and differential backups only capture changes made since the last backup, while a system restore point primarily focuses on system settings and configurations rather than full data backup.
