EMC Proven Professional – Information Storage Associate — Question 3

A customer is verifying the host environment before scheduling a VPLEX NDU. According to EMC best practices, which PowerPath load-balancing policy is applied by default to all platforms?

Answer options

• A. Adaptive
• B. RoundRobin
• C. LeastIO
• D. StreamIO

Correct answer: B

Explanation

The correct answer is B, RoundRobin, as it is the default load-balancing policy set by EMC for all platforms, ensuring even distribution of I/O across paths. The other options, A (Adaptive), C (LeastIO), and D (StreamIO), are alternative policies but are not the default setting, which may lead to suboptimal performance in certain scenarios.
