Which command would be used to establish static translation between an inside local address 192.168.144.25
and an inside global address 202.56.63.102?

A.
router(config)#ip nat inside source static 192.168.144.25 202.56.63.102

B.
router(config)#ip source nat inside static local-ip 192.168.144.25 global-ip 202.56.63.102

C.
router(config)#ip nat static inside source 192.168.144.25 202.56.63.102

D.
router(config)#ip nat inside static source 192.168.144.25 202.56.63.102

Explanation:
To establish a static translation between an inside local address 192.168.144.25 and an inside global address
202.56.63.102, you would use the ip nat inside source static 192.168.144.25 202.56.63.102 command executed
in global configuration mode. The correct format of the command is:
ip nat inside source static local-ip global-ip
This static configuration can be removed by entering the global no ip nat inside source static command.
Simply executing the ip nat inside source command will not result in NAT functioning. The NAT process also
has to be applied correctly to the inside and outside interfaces. For example, if, in this scenario the Fa0/0
interface hosted the LAN and the S0/0 interface connected to the Internet the following commands would
complete the configuration of static NAT.
Router(config)#interface F0/0
Router(config-if)#ip nat inside
Router(config-if)#exit
Router(config)#interface S0/0
Router(config-if)#ip nat outside
The other options are incorrect because they are not valid Cisco IOS configuration commands. They all contain
syntax errors.
