Dell EMC Associate – PowerEdge Server Specialist — Question 35

A server room has two power grids, A and B. PSU1 on each server is on grid A, and PSU2 is on grid B. Grid B has significantly lower load compared to grid A.
What is the most likely cause of the unbalanced power load?

Answer options

• A. PSU1 is a higher wattage power supply than PSU2
• B. Hot spare feature is enabled in power supply configuration
• C. PSU1 is always the primary power supply
• D. UPS and PDU are not installed to balance the load

Correct answer: B

Explanation

The correct answer is B because if the hot spare feature is enabled, PSU2 will only activate when PSU1 fails, resulting in PSU1 taking on the entire load under normal conditions. Options A and C suggest that the difference in wattage or primary status is causing the load imbalance, which isn't necessarily true. Option D implies a lack of equipment that could help balance the load, but it doesn't directly explain the current situation.
