The command that allows 14 hosts in a private network to access the Internet using a public IP pool is essential in Network Address Translation (NAT) configuration. By using the command 'ip nat inside source list 1 pool mypool overload', the router is configured to NAT the addresses of internal hosts to public addresses from the defined pool when they need to access the Internet.

The key part of this command is "overload," which enables Port Address Translation (PAT). PAT allows multiple hosts on a private network to be mapped to a single public IP address using different ports. This approach is particularly useful for networks with limited public IP addresses, allowing more internal devices to share access through one or a few public IPs.

Additionally, the mention of 'access list 1' indicates that there's a corresponding access-list configuration that permits traffic from the hosts that need Internet access. This command signifies that the router is set to recognize which internal IP addresses (defined in the access list) shall be translated using the defined public IP addresses in the 'mypool' pool.

The other choices do not provide the same functionality as the correct answer. While other commands might configure NAT in different contexts, they either don't specify the proper direction for translation or lack the
