• B. Information about the routing table
• C. Statistics on interface performance
• D. List of active VLANs on the switch

Answer: (A)

The command "show cdp neighbors" is specifically designed to display details of all directly connected devices that support Cisco Discovery Protocol (CDP). When this command is executed on a Cisco device, it provides a summary of neighboring devices, including their device IDs, local interface through which they are connected, and other characteristics such as capabilities and platform information. This tool is crucial for network administrators to quickly ascertain the topology of the network and understand how devices are interconnected. The output from this command enables administrators to view which devices are reachable, making troubleshooting and network management more efficient. This functionality underscores the importance of CDP in facilitating device discovery and gathering essential data regarding the network's architecture.
