Which two statements about static NAT are true? (Choose two.)
A.
An outside local address maps to the same outside global IP address.
B.
An inside local address maps to a different inside global IP address.
C.
An outside local address maps to a different outside global IP address.
D.
An inside local address maps to the same inside global IP address.
I don’t think D is correct. IMO it should be A and B.
@Max
It is A and D because they both need to be the SAME and not DIFFERENT.
Why do you say they have to be the same? I’ve never seen a router with the same ip address on its internal and external interface how would you map the same address (r u talking about extendable?)

inside global
ip nat inside source static 10.0.0.1 192.168.0.1
Another shit question. If required you can NAT both the source and destination IP, for example to reach another company and their IP clashes with yours.
But from an internet perspective, which was not specified, I think AB.
R1(config)#ip nat inside source static ?
A.B.C.D Inside local IP address
esp IPSec-ESP (Tunnel mode) support
network Subnet translation
tcp Transmission Control Protocol
udp User Datagram Protocol
R1(config)#ip nat inside source static 1.1.1.1 ?
A.B.C.D Inside global IP address
interface Specify interface for global address
R1(config)#ip nat inside source static 1.1.1.1 2.2.2.2 ?
extendable Extend this translation when used
mapping-id Associate a mapping id to this mapping
no-alias Do not create an alias for the global address
no-payload No translation of embedded address/port in the payload
redundancy NAT redundancy operation
route-map Specify route-map
vrf Specify vrf
A and D are correct, the word ‘same’ has been entered into the answers by mistake.
I would say B and C. If you map to the same address it means there is no change i.e. there is no NAT.
