Correct Answer: C
The command “ip nat inside source list 1 interface gigabitethernet0/0 overload” translates all source addresses that pass access list 1, which means 172.16.1.0/24 subnet, into an address assigned to gigabitethernet0/0 interface. Overload keyword allows to map multiple IP addresses to a single registered IP address (manyto-one) by using different ports so it is called Port Address Translation (PAT).
