Question

Power ________ is a Cisco feature that enables a switch to monitor the current draw of connected devices and to take action if the draw exceeds the amount allocated to the PD in accordance with its negotiated power class.

a. control
b. policing
c. monitoring
d. budgeting

Answer 1

Power Policing is a Cisco feature enabling a switch to monitor and manage the power draw of connected PoE devices to avoid overloads by taking corrective actions if necessary.

Step-by-step explanation:

The feature referred to in the question is Power Policing. Power Policing is a Cisco technology feature that allows a network switch to actively monitor and manage the electrical power provided to devices connected to it, such as phones, access points, and other Power over Ethernet (PoE) capable devices.

This Power Policing function ensures that devices do not exceed their allocated power draw based on the PoE class they negotiate upon connection. If a connected device (also known as a powered device or PD) tries to draw more power than what is allocated or what the switch is configured to provide, the switch can take corrective action. This action might include shutting down the PoE to the port, thus preventing potential overloads or damage to the switch.
