Dell EMC Specialist – Systems Administrator, Unity XT — Question 38

For Dell EMC SC Series arrays, what is the minimum percentage of total system IOPS that should be applied to Tier 3 drives?

Answer options

• A. 15%
• B. 20%
• C. 25%
• D. 100%

Correct answer: C

Explanation

The correct answer is C, as Tier 3 drives are typically used for less performance-sensitive workloads, and allocating 25% of total IOPS ensures adequate performance for those workloads. Options A and B provide too low a percentage, which could lead to insufficient resources for Tier 3 operations, while option D suggests an unrealistic allocation that is not necessary for Tier 3 drives.
