Question 2

Two enterprise networks must be connected together. Both networks are using the same private IP addresses.
The client requests from both sides should be translated using hide NAT (dynamic NAT) with the overload feature to save IF addresses from the NAT pools.
Which design addresses this requirement using only one Cisco I OS NAT router for both directions?

A. This is not possible, because two Cisco IOS NAT routers are required to do dynamic NAT, withoverload in both directions.
B. The ip nat inside and ip nat outside commands must be configured at the interfaces with theoverload option in both directions.
C. The overload feature is the default and does not have to be configured.
D. Two different NAT pools must be used for the ip nat inside source and the ip nat outside sourcecommands for the overload feature in both directions.
