题目

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
