D.
The Ethernet cable is not working
Answers
D.
The Ethernet cable is not working
Suggested answer: A

Explanation:

Power over Ethernet (PoE) delivers power to devices such as VoIP phones over the same cables used for data. If the total power requirement of connected devices exceeds the PoE power budget of the switch or injector, some devices may not receive adequate power and could intermittently reboot. This issue would not affect the workstation, which is likely receiving power separately.
