CompTIA Network+ (N10-009) — Question 402

Which of the following is the best way to keep devices on during a loss of power?

Answer options

• A. UPS
• B. Power load
• C. PDU
• D. Voltage

Correct answer: A

Explanation

A UPS (Uninterruptible Power Supply) provides backup power to devices during an outage, ensuring they remain operational. In contrast, a power load refers to the amount of power consumed, a PDU (Power Distribution Unit) distributes power but does not provide backup, and voltage is simply the electrical potential and does not offer a solution for power interruptions.
