CompTIA Server+ (SK0-004) — Question 17

A company executive asks the network administrator to help to reduce power consumption in a datacenter. The administrator suggests changing the servers running on 110V to 220V. Which of the following will occur as a result of this action?

Answer options

• A. The room temperature will be reduced
• B. Amperage consumed by each server will be reduced by 50%
• C. Twice as much heat will be generated in the server room
• D. Power redundancy will be added to the server by providing two 110V power sources

Correct answer: A

Explanation

Switching from 110V to 220V allows servers to draw less current (amperage) for the same power level, which can lead to a decrease in overall heat produced, hence reducing room temperature. Option B is incorrect because while the amperage decreases, it won't be reduced by 50% specifically. Option C is wrong because the change would not double heat generation; instead, it should lower it. Option D does not apply because it does not relate to the voltage change's effects on power redundancy.
