Answer options

• A. 1 group RAID 6 (14+2)
• B. 2 groups RAID 6 (6+2)
• C. 2 groups RAID 5 (7+1)
• D. 4 groups RAID 5 (3+1)

Correct answer: B

Explanation

The correct answer is B, as configuring the 10K drives in 2 groups of RAID 6 (6+2) provides a good balance between performance and data protection, which is essential for the organization sensitive to data loss. Options A, C, and D do not offer the same level of redundancy or performance as RAID 6, making them less suitable for this scenario.
