CompTIA Security+ (SY0-501) — Question 55

A database backup schedule consists of weekly full backups performed on Saturday at 12:00 a.m. and daily differential backups also performed at 12:00 a.m. If the database is restored on Tuesday afternoon, which of the following is the number of individual backups that would need to be applied to complete the database recovery?

Answer options

• A. 1
• B. 2
• C. 3
• D. 4

Correct answer: B

Explanation

To restore the database on Tuesday afternoon, you would need the last full backup from Saturday and the differential backup from Monday. Therefore, a total of 2 backups are required: the full backup and one differential backup. The other options are incorrect as they do not account for both the full and differential backups needed for a complete recovery.
