CompTIA Server+ (SK0-004) — Question 18

A server has five hot swappable drives in a hardware RAID 5 configuration. One of those drives has issued a predictive failure warning to the server's management console. Which of the following is the BEST course of action?

Answer options

• A. Replace the drive and restore data from backup
• B. Reformat the drive and restore data from backup
• C. Reformat the drive and have the RAID controller rebuild the configuration
• D. Replace the drive and have the RAID controller rebuild the configuration

Correct answer: C

Explanation

The best action is to replace the failing drive and have the RAID controller rebuild the configuration, as this allows for data integrity to be maintained without needing to restore from backup. Reformatting the drive (Options B and C) is unnecessary, and restoring data from backup (Option A) is not required in this scenario since the RAID can handle the failure and rebuild itself.
