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?

A. B. C. D.C.
The BEST course of action in this scenario would be to replace the drive and have the RAID controller rebuild the configuration.
Explanation:
A predictive failure warning indicates that the drive is likely to fail in the near future, so it is important to take action to prevent data loss. The server has a hardware RAID 5 configuration, which means that data is distributed across all five drives and any one drive can fail without data loss.
Option A suggests replacing the drive and restoring data from backup, but this would involve downtime and data loss. In addition, RAID 5 is designed to tolerate the loss of one drive, so restoring from backup is not necessary unless additional drives fail.
Option B suggests reformatting the drive and restoring data from backup, but this would result in data loss and is not a viable option.
Option C suggests reformatting the drive and having the RAID controller rebuild the configuration. While this may work, it is a risky option as it may result in data loss. RAID 5 can only tolerate the loss of one drive, so rebuilding the configuration with a failing drive may cause additional drive failures and data loss.
Option D suggests replacing the drive and having the RAID controller rebuild the configuration, which is the best course of action. The RAID controller will automatically rebuild the data from the failed drive onto the replacement drive, ensuring that no data is lost and that the server can continue to operate normally.
Therefore, the BEST course of action would be to replace the drive and have the RAID controller rebuild the configuration.
