CompTIA Security+ (SY0-501) — Question 1022

Which of the following would allow for the QUICKEST restoration of a server into a warm recovery site in a case in which server data mirroring is not enabled?

Answer options

• A. Full backup
• B. Incremental backup
• C. Differential backup
• D. Snapshot

Correct answer: A

Explanation

A Full backup is the quickest way to restore a server because it contains all the data needed to return to the most recent state, allowing for a complete restoration in one step. Incremental and differential backups require additional steps to restore since they only contain changes since the last backup, making them slower. A snapshot captures the current state but does not provide a complete recovery solution on its own without a backup.
