Question:
A network engineer has configured a router with the command ip nat inside source list 4 pool corp overload. Why did the engineer use the overload option?

• The company router must throttle or buffer traffic because the processing power of the router is not enough to handle the normal load of external-bound Internet traffic.
• The company has more private IP addresses than available public IP addresses.
• The company needs to have more public IP addresses available to be used on the Internet.
• The company has a small number of servers that should be accessible by clients from the Internet.

Explanation: The overload option enables PAT for a pool of public IP addresses. The source list 4 part of the command refers to the access list that defines what private addresses get translated. The pool corp part of the command refers to the named NAT pool that is created using the separate ip nat pool corp command.
