39What is true regarding the differences between NAT and PAT?
PAT uses the word "overload" at the end of the access-list statement to share a single registered address.
Static NAT allows an unregistered address to map to multiple registered addresses.Dynamic NAT allows hosts to receive the same global address each time external access is required.
PAT uses unique source port numbers to distinguish between translations.
