To answer this question, you need to understand the concept of RAID 5.
RAID 5 is a redundant array of independent disks that uses block-level striping with distributed parity. It requires a minimum of 3 drives to be created.
Let's go through each option to understand why it is correct or incorrect:
Option A) 3 - This option is correct because RAID 5 requires a minimum of 3 drives. It uses block-level striping with distributed parity, where the data and parity information are distributed across the drives.
Option B) 5 - This option is incorrect because RAID 5 does not require 5 drives. It only requires a minimum of 3 drives.
Option C) 2 - This option is incorrect because RAID 5 cannot be created with only 2 drives. It requires a minimum of 3 drives.
Option D) 4 - This option is incorrect because RAID 5 does not require 4 drives. It only requires a minimum of 3 drives.
The correct answer is Option A) 3. This option is correct because RAID 5 requires a minimum of 3 drives to be created.
