What is the primary purpose of LLDP?

To exchange routing information between Layer 3 devices

To provide authentication and encryption for network management traffic

To allow network devices to advertise their identity and capabilities to directly connected neighbors

To synchronize clock settings between network devices

A network engineer is configuring a Cisco switch that connects to a third-party IP phone. The phone supports LLDP but not CDP. The engineer wants to ensure the switch can discover the phone. What should the engineer do?

Enable LLDP only on the interface

Enable LLDP globally and on the interface

Enable CDP globally and on the interface

A network engineer is troubleshooting LLDP on a Cisco switch and wants to confirm that LLDP is enabled globally and that the switch is receiving LLDP frames on a specific interface. Which two commands should be used?

show running-config and show lldp neighbors

show lldp neighbors and show lldp traffic

show lldp local and show lldp traffic

show lldp and show lldp interface
