Which configuration correctly sets up a mirrored system volume and a RAID 5 data volume for the specified disks?

• A. Mirror System (C:) to Disk 1 and create RAID 5 volume across Disk 2, Disk 3, and Disk 4 with Drive letter R and label Data
• B. Create RAID 0 across all disks
• C. Mirror System (C:) to Disk 2 and create RAID 5 across Disk 1, Disk 3, Disk 4
• D. Create a simple volume on Disk 4

Answer: (A)

The setup is testing the ability to provide OS resilience while also protecting data with a separate fault-tolerant storage, using the right mix of mirror and parity arrays. Mirroring the system volume keeps a live copy of the C: drive on another disk, so the system can boot from either disk if one fails. At the same time, creating a RAID 5 volume across three other disks uses striping with distributed parity, allowing the array to survive a single disk failure and making efficient use of disk space. Assigning the data volume a separate drive letter (R) and a Data label helps keep the OS and data clearly organized. The best arrangement mirrors the system volume to the first disk and forms the RAID 5 data array on the remaining three disks, with the data volume on a separate drive letter. This meets both goals: OS protection through mirroring and data protection through RAID 5. Other options don’t provide this combination. RAID 0 across all disks offers no fault tolerance. Mirroring the OS to a disk other than the specified first disk or mixing the RAID 5 array across disks differently won’t meet the intended disk mapping. A simple volume on a single disk has no redundancy at all.
