Dell Technologies Proven Professional – Midrange Storage Solutions — Question 24

What is skew?

Answer options

• A. Uniform distribution of I/O over storage capacity
• B. Bursty per-port IOPS
• C. Non-uniform distribution of I/O over storage capacity
• D. Sustained per-port IOPS

Correct answer: C

Explanation

The correct answer is C, as skew refers to the non-uniform distribution of I/O, indicating that some parts of the storage may experience significantly more I/O than others. Options A and D describe uniform distribution and sustained IOPS, respectively, which do not accurately reflect the concept of skew. Option B mentions bursty IOPS, which is related but does not define skew in terms of distribution.
