CDP is a Cisco proprietary protocol that shares what type of information about neighboring devices?

• A. Routing tables
• B. Switching topologies
• C. Neighbor information of connected Cisco devices
• D. Interface statistics

Answer: (D)

CDP is used to discover details about devices that are directly connected to a Cisco device. It shares neighbor information such as the device identifier (hostname), the IP address used to reach the neighbor, the platform/model, the capabilities of the neighbor, and which port on the neighbor is connected (port ID). This lets you quickly map who is directly adjacent and how the devices are linked, which is invaluable for troubleshooting and network mapping. It does not transmit routing tables, it does not reveal a full switching topology, and it does not provide interface statistics—that kind of data comes from other tools and protocols.
