The correct answer is B. Purchase servers with hot swappable drives configured in a RAID. To minimize downtime from hard drive failures, an administrator should recommend servers equipped with hot-swappable drives configured in a RAID array, which provides both data redundancy and easy component replacement.

Why each option
To minimize downtime from hard drive failures, an administrator should recommend servers equipped with hot-swappable drives configured in a RAID array, which provides both data redundancy and easy component replacement.
While mirroring disks (a type of RAID) provides data redundancy, it doesn't inherently address the downtime associated with replacing a failed drive unless combined with hot-swappable capabilities.
Hot-swappable drives allow for a failed drive to be replaced while the server remains powered on and operational, preventing downtime. Configuring these drives in a RAID (Redundant Array of Independent Disks) array provides data redundancy, ensuring the system can continue functioning even if one drive fails.
RAID 0 (striping) offers no data redundancy; if any drive in a RAID 0 array fails, all data is lost, leading to significant downtime.
Performing timely backups is crucial for data recovery but does not prevent downtime caused by a failed hard drive or allow the system to continue operating during a failure.
