CompTIA A+ Core 1 (220-1101) — Question 212

A technician is working on a critical warehouse machine that will not turn on. The technician has determined the power supply for the machine failed. The warehouse manager is looking for a solution that will prevent downtime in the future. Which of the following devices should the technician install to meet this requirement?

Answer options

Correct answer: D

Explanation

The correct choice is D, as a Redundant power supply provides a backup in case the primary power supply fails, thus ensuring continuous operation and minimizing downtime. Options A, B, and C do not offer redundancy and would not effectively prevent future power supply failures.
