CompTIA Server+ (SK0-004) — Question 42

An administrator is creating an on-site backup and an off-site backup for four servers located at the company's headquarters. Which of the following backup options should the administrator select to meet the requirements?

Answer options

• A. A daily backup of each server to its secondary disks and a nightly cross-backup to the network drives of one of the other servers
• B. An hourly backup of each server to a NAS drive at the MDF and a nightly backup to another NAS drive at the IDF of the headquarters
• C. A daily backup of each server to a SAN volume at the headquarters and a weekly backup to a NAS drive at a colocation
• D. A continuous replication backup to the NAS drive in the server room and a nightly backup to the backup server at the HQ telecom closet

Correct answer: D

Explanation

The correct answer, D, provides a continuous replication backup for immediate data protection and a nightly backup for additional redundancy. Options A, B, and C do not meet the requirement of ensuring both on-site and off-site backups effectively, as they either lack off-site storage or do not provide the necessary frequency of backups.
