第8题：

You have just installed a new web server on the Ezonexam network. You are required to ensure that the web server is accessible from the Internet. The network uses private addressing, so an IP-to-registered address mapping is required.

To do this, you enter the following command:

Ezonexam(config)# ip nat inside source static 192.168.2.1

198.18.1.254

You unsuccessfully try to ping the Internet from a PC host on the LAN. During the troubleshooting process, you enter the "show ip nat translations" command but the output is blank.

What is the most likely cause of the problem?

A．The keyword overload is missing from the command.

B．The NAT pool must be defined first.

C．An access list must be defined to create static NAT translations.

D．The interfaces must be configured for NAT.

E．None of the above

正确答案：D
解析：Explanation:
In order to successfully configure a static NAT translation, the interfaces must be configured for NAT, in addition to the global NAT command that was entered. The router interface that lies on the inside part of the network must be defined using the "ip nat inside" command. Similarly, the WAN interface that is being used for the Internet connection must be defined using the "ip nat outside" command.

Incorrect Answers:
A. In order to make an internal server reachable from the Internet, a static one to one NAT entry must be configured for the server. The keyword "overload" is used to configure many to one NAT, or PAT.

B, C. This need not be done in order to create a static NAT entry. These steps are typically done in setting up NAT so that inside LAN users can access the Internet via NAT.
