Which two mechanisms does Cisco EnergyWise use for neighbor discovery? (Choose two.)

A. multicast

B. LLDP-MED

C. UDP broadcast

D. Cisco Discovery Protocol

E. TCP

Answer: C, D

Explanation:

Cisco EnergyWise Neighbor Discovery Process

The Cisco EnergyWise neighbor discovery process is the mechanism by which domain members discover each other and populate their Cisco EnergyWise neighbor tables. Cisco EnergyWise queries can subsequently be distributed to all domain members using the neighbor relationships to monitor and control the power usage of devices within a domain. Cisco EnergyWise domain members automatically discover their neighbors through one of two mechanisms:

Cisco EnergyWise UDP broadcast packet

Cisco EnergyWise CDP packets

UDP broadcast packets are automatically sent out switch ports which support Cisco EnergyWise, regardless of whether the interfaces are configured with the no energywise interface-level command. CDP packets are sent when CDP is configured for the switch ports.
