Which form of NAT performs bi-directional translation?

A.
VIP

B.
MIP

C.
DIP

D.
Nat-dst

E.
NAT-src

Explanation:
A MIP is a mapping of one IP address to another IP address. You define one address in the same subnet as an interface IP address. The other address belongs to the host to which you want to direct traffic. Address translation for a MIP behaves bidirectionally, so that the NetScreen device translates the destination IP address in all traffic coming to a MIP to the host IP address and source IP address in all traffic originating from the host IP address to the MIP address. MIPs do not support port mapping.
