CompTIA Network+ (N10-007) — Question 10

To replace a defective UPS, the network administrator must take the switch offline. The administrator wants to be able to perform maintenance UPS in the future without affecting the availability of the attached switch. Which of the following would BEST allow this to happen?

Answer options

Correct answer: A

Explanation

The correct answer is A, as adding a redundant power supply ensures that the switch remains operational even if one power source fails, thus allowing UPS maintenance without downtime. Options B, C, and D do not provide the same level of reliability and redundancy for power supply as a redundant power supply does.
