Which two statements about static NAT translations are true? (choose two)
A.
They are always present in the NAT table.
B.
They allow connection to be initiated from the outside.
C.
They can be configured with access lists, to allow two or more connections to be initiated from the outside.
D.
They require no inside or outside interface markings because addresses are statically defined.
With static NAT, translations exist in the NAT translation table as soon as you configure static NAT command(s), and they remain in the translation table until you delete the static NAT command(s).
With dynamic NAT, translations do not exist in the NAT table until the router receives traffic that requires translation. Dynamic translations have a timeout period after which they are purged from the translation table.
-> A is correct.
Because static NAT translations are always present in the NAT table so outside hosts can initiate the connection without being dropped -> B is correct.
Static translations can not be configured with access lists. To configure static NAT, we only need to specify source IP, NAT IP, inside interface & outside interface.
-> C is not correct.
We have to specify which is the inside and outside interface -> D is not correct.
For your information, below is an example of configuring static NAT:
R0(config)#int f0/0
R0(config-if)#ip nat inside
R0(config-if)#int f0/1
R0(config-if)#ip nat outside
R0(config)#ip nat inside source static 10.0.0.1 200.0.0.2
