CompTIA A+ Core 2 (220-1002) — Question 404

Which of the following is the MOST cost-effective option to protect computers and peripherals from damage caused by power fluctuations?

Answer options

• A. Generator
• B. Battery backup
• C. Surge suppressor
• D. Line conditioner

Correct answer: C

Explanation

A surge suppressor is the most cost-effective solution as it specifically protects against voltage spikes and surges, which are common power fluctuations. Generators and battery backups are more expensive and provide backup power rather than protection from surges. A line conditioner improves power quality but is typically more costly than a surge suppressor.
