第1题：

At which layer of the OSI model does the protocol that provides the information displayed by the "show cdp neighbors" command operate?

A．Transport

B．Physical

C．Application

D．Data link

E．Network

正确答案：D
解析：Explanation:
CDP is a device discovery protocol that runs over Layer 2 (the data link layer) on all Cisco-manufactured devices (routers, bridges, access servers, and switches) and allows network management applications to discover Cisco devices that are neighbors of already known devices. With CDP, network management applications can learn the device type and the Simple Network Management Protocol (SNMP) agent address of neighboring devices running lower-layer, transparent protocols.

正确答案：AB
A,B 解析：Explanation:
A WAN is a data communications network that covers a relatively broad geographic area and that often uses transmission facilities provided by common carriers, such as telephone companies. WAN technologies generally function at the lower two layers of the OSI reference model: the physical layer and the data link layer as shown below.

Note: Occasionally WAN's would also be considered to operate at layer 3, but since this question asked for only 2 chopices layers 1 and 2 are better choices.
