Final answer:
To install a RAID 1 configuration, the minimum number of disks required is 2. This setup provides data redundancy by mirroring the data across the drives.
Step-by-step explanation:
The minimum number of disks that can be used to create a RAID 1 array is 2. RAID 1 is known as mirroring and involves copying (or mirroring) the same data across multiple drives. This setup ensures that if one drive fails, the system can continue to operate using the other drive as it contains an exact copy of the data. Therefore, the correct answer to the student's question is B. 2.The minimum amount of disks that can be used to create a RAID 1 array is 2. RAID 1, also known as mirroring, involves creating an exact copy of data on multiple disks. In this configuration, if one disk fails, the other disk can still provide the necessary data. So, to ensure redundancy and fault tolerance, a minimum of 2 disks are required for RAID 1.
