Policy 1 is applied on outbound (LAN-WAN) and policy 2 is applied on inbound (WAN-LAN). question is asking SNAT for outbound traffic so policy 1 will take place and NAT overload is in effect.

Is it correct to say that if you had the REAL (Mapped IP) of 10.0.1.10 as the source in the first rule instead of "all" the SNAT would use te VIPs address of 10.200.1.10 ?

No because it is outbound traffic. If it was inbound traffic then it would us the VIPs address.

Selected Answer: A

traffic coming from a workstation has unspecified target (not the Webserver) so- policy 1 and ip overload matches
