Which action is taken by a switch port enabled for PoE power (CCNA 200-301)
Which action is taken by a switch port enabled for PoE power classification override?
A. As power usage on a PoE switch port is checked data flow to the connected device is temporarily paused
B. When a powered device begins drawing power from a PoE switch port, a syslog message is generated
C. If a switch determines that a device is using less than the minimum configured power, it assumes the device has failed and disconnects it
D. Should a monitored port exceed the maximum administrative value for power, the port is shut down and err-disabled
Solution
Correct answer: D. Should a monitored port exceed the maximum administrative value for power, the port is shut down and err-disabled.
When a switch port is enabled for PoE power classification override, it allows the switch to override the power classification of a device and enforce a specific power limit. If the device exceeds this limit, the switch will take action to prevent damage or overload. In this case, the switch will shut down the port and put it in an err-disabled state.
