Which command creates a static NAT mapping from internal host 10.1.1.1 to public address 209.165.200.225?

The correct command is ip nat inside source static 10.1.1.1 209.165.200.225 because it correctly specifies that the translation is for traffic originating from the inside network (inside source), and it maps the internal private IP address (10.1.1.1) to the external public IP address (209.165.200.225). Static NAT creates a one-to-one, permanent mapping. The inside keyword refers to the interface connected to the private network, and source indicates that the translation applies to the source IP address of packets originating from the inside. The incorrect options either use outside incorrectly (which would be for traffic originating from the outside network) or reverse the order of the private and public IP addresses.
