CompTIA Network+ (N10-009) — Question 390

Which of the following can protect network equipment from voltage variations?

Answer options

• A. MDF
• B. Power strips
• C. PDU
• D. UPS

Correct answer: C

Explanation

A PDU (Power Distribution Unit) is specifically designed to manage and distribute power to multiple devices while protecting them from voltage variations. Although a UPS (Uninterruptible Power Supply) can also provide power protection, the PDU is the most relevant option here for protecting network equipment directly from voltage fluctuations. MDF (Main Distribution Frame) and power strips do not offer the same level of protection against voltage variations.
