CompTIA A+ Core 1 (220-1201) — Question 135

A customer recently lost data due to several unexpected shutdowns. Data integrity is important to the customer. Which of the following features should the technician choose to prevent data loss?

Answer options

• A. Redundant power supply
• B. Uninterruptible power supply
• C. Modular power supply
• D. High-efficiency power supply

Correct answer: B

Explanation

The correct choice is B, the Uninterruptible power supply (UPS), as it provides backup power during outages, allowing systems to continue running long enough to save work and prevent data loss. The other options, while beneficial for power management, do not offer the same level of protection against sudden power failures.
