Dell EMC Associate – Backup and Recovery Solutions Design v2 — Question 22

A full backup of a production volume is created on Sunday, and incremental backups are created for the rest of the week. What are the contents of the backup on Thursday?

Answer options

• A. all the data on the production volume
• B. all the data that has changed since Wednesday
• C. all the data that has changed since Sunday
• D. all the data that has changed since Monday

Correct answer: B

Explanation

The correct answer is B because incremental backups only include the data that has changed since the last backup, which in this case is Wednesday. Option A is incorrect as it refers to a full backup, while options C and D refer to changes from earlier points in the week, not just since Wednesday.
