A standard virtual server is defined with a pool and a SNAT using automap. All other settings for the virtual server are at defaults. When client traffic is processed by the BIG-IP, what will occur to

This describes traffic initiated by pool members (outbound traffic), whereas the question is about client traffic initiated to the virtual server.

A standard virtual server's primary function is to receive client connections destined for its own IP address and then forward these connections to a member of its associated pool. This process inherently involves Destination Network Address Translation (DNAT), where the destination IP address of the client's packet is changed from the virtual server's IP to the IP address of the chosen pool member. This ensures the traffic reaches an available backend server.

SNAT Automap, when enabled on a virtual server, translates the source IP address of all client connections processed by that virtual server to a BIG-IP self-IP address, not just those from "selected clients based on their IP address."

This statement is identical to choice B and provides the same correct information regarding the destination address translation performed by a standard virtual server.
