A. B. C. D.B.
To set up a RAID 1 array for the boot partition, at least two disks are required. RAID 1, also known as mirroring, involves creating an exact copy of one disk onto another disk. This provides redundancy in case one of the disks fails, ensuring that the server can still boot from the remaining disk.
To set up a RAID 5 array for the data partition, at least three disks are required. RAID 5 involves striping data across multiple disks, with parity information distributed across all the disks. This provides both redundancy and improved performance.
Therefore, the minimum number of disks needed to implement both partitions is the maximum of the number of disks required for each partition, which is three. So the answer is (B) 5.
The technician can install two disks for the RAID 1 array and three additional disks for the RAID 5 array. This would result in a total of five disks.
