CCNA: Cisco Certified Network Associate — Question 431

Which action is taken by a switch port enabled for PoE power classification override?

Answer options

• 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

Correct answer: D

Explanation

The correct answer is D because a switch port enabled for PoE power classification override will shut down and go into an err-disabled state if it exceeds the maximum power threshold. Options A, B, and C do not accurately describe the behavior of a PoE switch port under these conditions and focus on different scenarios that do not apply to power classification overrides.
