Refer to the exhibit. Based on the output that is shown, what type of NAT has been implemented?
- dynamic NAT with a pool of two public IP addresses
- PAT using an external interface
- static NAT with a NAT pool
- static NAT with one entry
Explanation: The output shows that there are two inside global addresses that are the same but that have different port numbers. The only time port numbers are displayed is when PAT is being used. The same output would be indicative of PAT that uses an address pool. PAT with an address pool is appropriate when more than 4,000 simultaneous translations are needed by the company.
