    C,D

    C: to make static NAT for destination IP on VR-1 to allow traffic from User-1 to Server-1

    D: to make Static Nat for source ip of user-1 to allow its source ip to be the ip of Ge-0/0/2.0 (192.1681.x/24) of VR-A to allow return traffic from Server-1 to user-1

    Hey guys had you seen that questions require two answer (choose two!!!) OH my God.
    Anyway why should be D, which is the egress interface here??? Ge-0/0/2.0 or Ge-0/0/3.0?

    Hi,
    “D” for sure not the option. If I am not wrong there is no option in Static NAT configuration to mention “to zone”; secondly, static nat cannot be used with interface. So option D is syntax issue.
    I think, B & C are better options.

    answer should be A & C because

    C > as you want to communicate with server in VR.a

    A > even if you dont specify VR, you can add instance Import or RIB-GRP to import A routes to untrust.
