Question 410

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?

    Correct Answer: B

    RAID 1 would best meet the requirement of data redundancy with the fewest drives possible. RAID 1, also known as mirroring, requires only two drives to create a redundant copy of the data. In case one drive fails, the data remains available on the second drive, ensuring data redundancy. Other RAID configurations like RAID 5 and RAID 10 require more drives, while RAID 0 does not provide any redundancy.

edwinvOption: B

For a storage solution that requires data redundancy with the fewest drives possible, the best option would be: B. RAID 1 Explanation: RAID 1, also known as mirroring, provides data redundancy by duplicating the data across two drives. This means that if one drive fails, the data is still available on the mirrored drive, ensuring high reliability. RAID 0 (Option A) provides striping without redundancy, and RAID 5 (Option C) and RAID 10 (Option D) offer both striping and redundancy but require more drives than RAID 1. RAID 10 (RAID 1+0) combines mirroring and striping and requires a minimum of four drives. RAID 5 requires a minimum of three drives, and RAID 0 doesn't provide redundancy.

It says fewest possible drives. RAID 0 and 1 require two drives minimum. RAID 5 requires 3 and 10(1+0) requires 4. So RAID 1 is the least amount of drives and provides data redundancy.

BhrinoOption: B

the question only ask for redundancy and not speed, pairity, or both so im going with B
