CompTIA Network+ (N10-007) — Question 149

Company policy dictates that full backups are taken every Sunday evening, and incremental backups occur Monday through Saturday in the evening. If data loss were to occur on a Thursday before the backup window, which of the following is the number of backup sets that would be needed to retrieve the lost data come
Friday morning?

Answer options

• A. 1
• B. 2
• C. 3
• D. 4
• E. 5

Correct answer: D

Explanation

To recover the lost data, you would need the full backup from Sunday and the incremental backups from Monday, Tuesday, and Wednesday, totaling four backup sets. The full backup provides the baseline, and the three incrementals capture changes made through the week. Options A, B, and C do not account for all necessary backups to restore the lost data.
