Cisco CCNA 200-301 Practice Question

To allow multiple internal hosts to access the internet simultaneously using a single public IP address, you should configure Dynamic NAT with overload. This method, also known as Port Address Translation (PAT), maps multiple private IP addresses to a single public IP address by differentiating sessions with unique source port numbers. Static NAT maps one private IP to one public IP, and Dynamic NAT without overload requires a pool of public IPs equal to the number of concurrent sessions, which doesn't meet the requirement of using a single public IP. Static NAT with overload is not a standard or valid configuration.
