第1题：

While troubleshooting a connectivity problem on the network, you issue the ping command from your PC command prompt, but the output shows "request times out."

At which OSI layer is this problem associated with?

A．The data link layer

B．The application layer

C．The access layer

D．The session layer

E．The network layer

正确答案：E
解析：Explanation:
TCP/IP includes ICMP, a protocol designed to help manage and control the operation of a TCP/IP network. The ICMP protocol provides a wide variety of information about a network's health and operational status. Control message is the most descriptive part of a name. ICMP helps control and manage IP's work and therefore is considered part of TCP/IP's network layer.

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.
