CompTIA A+ Core 2 (220-1002) — Question 201

Which of the following should be replaced after a voltage spike?

Answer options

• A. Surge suppressor
• B. Battery backup
• C. Power supply
• D. Electrical cable

Correct answer: C

Explanation

The power supply is designed to convert and regulate voltage, and it is vulnerable to damage during a voltage spike. A surge suppressor is meant to protect against such spikes, while a battery backup and electrical cables are typically not directly affected in the same way, making them less likely to need replacement after a spike.
