What command would be used to display any dynamic PAT translations that have been created by traffic?

The command used to display any dynamic Port Address Translation (PAT) translations created by traffic is "show ip nat translation." This command reveals the current translations that have occurred on the router, showing how local IP addresses and ports have been mapped to a public IP address and port.

When a device on a private network sends traffic to the internet, the router or firewall performs dynamic PAT by replacing the private IP address and port with its own public IP address and a unique port number. By using the "show ip nat translation" command, network administrators can effectively monitor and troubleshoot NAT configurations. This information is crucial for understanding how internal addresses are translated and for resolving any issues related to NAT.

The other command options serve different purposes. For example, "show ip nat statistics" displays statistical data related to NAT operations, but it does not show the specific translation entries. The "show ip access-lists" command provides information about configured Access Control Lists (ACLs) rather than NAT translations. Lastly, "show ip interface brief" presents a summary of the status and IP addresses of interfaces but does not relate to NAT translations.
