Dell EMC Associate – Information Storage and Management v5 — Question 80

A host sends one write I/O to the RAID 1 array.
How many writes does it take for the array to store the data?

Answer options

• A. Two write I/Os
• B. One write I/Os
• C. Six write I/Os
• D. Four write I/Os

Correct answer: A

Explanation

The correct answer is A, as RAID 1 involves mirroring data across two disks. Therefore, when a host sends one write I/O, it must be written to both disks, resulting in two write I/Os. The other options incorrectly reflect the actual number of writes needed for data redundancy in a RAID 1 setup.
