EMC Information Storage Fundamentals — Question 16

What describes an advantage of the changed block tracking backup technique?

Answer options

• A. Increase backup device performance
• B. Enable restoration to any point-in-time
• C. Eliminate the need for data deduplication
• D. Reduce the backup window

Correct answer: A

Explanation

The correct answer is A because changed block tracking improves the performance of backup devices by only copying blocks that have changed since the last backup. Options B, C, and D are not advantages of this technique, as it does not inherently allow for point-in-time restoration, eliminate the need for deduplication, or reduce the backup window.
