CompTIA Network+ (N10-009) — Question 159

A network rack has four servers and four switches with dual power supplies. Only one intelligent PDU is installed in the rack. Which of the following is the reason to add a second PDU?

Answer options

• A. Power redundancy
• B. Failed PSU monitoring
• C. Surge protection
• D. Electricity conservation

Correct answer: A

Explanation

Adding a second PDU provides power redundancy, ensuring that if one PDU fails, the other can maintain power to the devices. The other options, while important, do not address the critical need for redundancy in power supply, which is essential for preventing downtime in the event of a failure.
