CompTIA Network+ (N10-009) — Question 203

A user’s VoIP phone and workstation are connected through an inline cable. The user reports that the VoIP phone intermittently reboots, but the workstation is not having any network-related issues. Which of the following is the most likely cause?

Answer options

• A. The PoE power budget is exceeded.
• B. Port security is violated.
• C. The signal is degraded.
• D. The Ethernet cable is not working.

Correct answer: A

Explanation

The most likely cause of the VoIP phone rebooting is that the PoE power budget is exceeded, which can result in insufficient power being supplied to the device. The other options do not directly address the power supply issues required for the VoIP phone, as port security violations, signal degradation, and a malfunctioning Ethernet cable would typically impact both devices or present different symptoms.
