Question

A branch router connects an internal network of 200 hosts (192.168.10.0/24) to the Internet. The ISP assigned a small block of 4 public addresses (203.0.113.4 through 203.0.113.7). The administrator must allow all 200 internal hosts to access the Internet simultaneously using these public addresses. Which NAT configuration approach should be used?

Accepted Answer

Configure a dynamic NAT pool of the four addresses with the overload keyword (PAT)

Answer

Configure a dynamic NAT pool of the four addresses without the overload keyword

Answer

Configure 200 static NAT entries mapping each host to a public address

Answer

Configure static NAT for the first four hosts and leave the rest without translation
