A network technician is troubleshooting connectivity problems between switches but suspects the ports are not properly labeled. Which of the following options will help to quickly identify the switches connected to each port?

  1. Configure TACACs on each network device.

  2. Enable a discovery protocol on the network devices.

  3. Configure each uplink to send LACP discovery units.

  4. Enable a packet sniffer on each network device’s uplink port.

Answer: B Explanation:

“Neighbor discovery protocols are essential for network administrators and management tools to accurately construct a view of the network topology. Each manufacturer has its own supported mix of neighbor discovery protocols, loosely based on how standards-focused that vendor is and how much it wants to pay in royalties to use proprietary protocols. The two most widely used are LLDP (Link Layer Discovery Protocol), an IEEE standard, and CDP (Cisco Discovery Protocol).”
