CompTIA A+ Core 1 (220-1101) — Question 312
A technician is installing a storage solution for a computer that requires data redundancy with the fewest drives possible. Which of the following would best meet this requirement?
Answer options
- A. RAID 0
- B. RAID 1
- C. RAID 5
- D. RAID 10
Correct answer: B
Explanation
RAID 1 provides data redundancy by mirroring the data across two drives, ensuring that if one drive fails, the data remains safe on the other. RAID 0 offers no redundancy but improves performance, while RAID 5 and RAID 10 require more drives to achieve redundancy, making them less efficient for this specific requirement.
