.You are configuring the link between a Cisco 2950 series switch and a Cisco 2611 router. You have physically connected the router’s Ethernet port to the switch using a straightthrough
cable. The switch has not been configured, except for a hostname. The router’s hostname has also been configured, and the Ethernet port has been enabled. However, you
forgot to assign an IP address to the Ethernet port.
You issue the show cdp neighbors command and get the following output:
If you did not configure IP addresses, how is this information being passed between the two devices?
A. The devices established a connection using default IP addresses.
B. The ip unnumbered command has been issued, which means the interface does not require an IP address to be configured.
C. CDP is a Layer 2 protocol and does not require IP addresses to be configured.
D. CDP uses its own IP addressing system.
