CompTIA A+ Core 1 (220-1101) — Question 249

An engineer is installing a 500W power supply in a server that requires continuous availability. Which of the following is the most suitable type of power supply for the application?

Answer options

• A. Redundant
• B. Modular
• C. Switched-mode
• D. Semi-modular

Correct answer: A

Explanation

The correct answer is A, Redundant, as it provides backup power in case one supply fails, ensuring continuous availability. Options B, C, and D do not offer the same level of failover protection, making them less suitable for a server that requires uninterrupted power.
