   A PowerEdge R740xd server is configured with a PERC H740P controller and a backplane that supports 24 drives. The administrator creates a RAID 10 array using 12 drives and a RAID 5 array using the remaining 12 drives. The OS is installed on the RAID 10 array. What is the correct description of how the PERC controller presents these arrays to the operating system?

   • AThe OS sees a single virtual disk that combines both RAID arrays into one logical volume.
   • BThe OS sees the RAID 10 array as a virtual disk, but the RAID 5 array is not visible until it is initialized.
   • CThe OS sees all 24 drives as individual disks, and the RAID arrays are managed by the OS.
   • DThe OS sees two separate virtual disks, one for each RAID array, and the PERC manages them independently.
