CompTIA A+ Core 2 (220-1102) — Question 3

A technician needs to recommend the best backup method that will mitigate ransomware attacks. Only a few files are regularly modified; however, storage space is a concern. Which of the following backup methods would BEST address these concerns?

Answer options

Correct answer: B

Explanation

The Differential backup method is the best choice because it only backs up changes made since the last full backup, thus requiring less storage space compared to a Full backup. Unlike Full backups, which save all data and can consume significant storage, Differential backups are efficient for infrequently modified files. Off-site and Grandfather-father-son options do not specifically address the need for efficient storage use while protecting against ransomware.
