CompTIA Network+ (N10-008) — Question 772

A technician is trying to install a VoIP phone, but the phone is not turning on. The technician checks the cable going from the phone to the switch, and the cable is good. Which of the following actions is needed for this phone to work?

Answer options

• A. Add a PoE injector.
• B. Enable MDIX.
• C. Use a crossover cable.
• D. Reconfigure the port.

Correct answer: A

Explanation

The correct answer is A because VoIP phones often require Power over Ethernet (PoE) to operate, which a PoE injector can provide. The other options, such as enabling MDIX or using a crossover cable, are not relevant to powering the device, and reconfiguring the port would not address the lack of power issue.
