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

Answer: D

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.
