Question 31

In a routed configuration, what does LTM do with the packet before sending it to the pool member?

    Correct Answer: D

    In a routed configuration, the LTM (Local Traffic Manager) modifies the destination IP address of the packet to match the IP address of the appropriate pool member. It leaves the source IP address unchanged, allowing the return traffic to be directed properly back through the LTM. This ensures that the flow of the session is maintained and that the LTM can consistently manage the traffic and load balancing.

Discussion
TimberOption: B

If by routed configuration, they mean "IP Forwarding Virtual Server", then no translation is expected. So Answer should be "B".

Not true, it changes the destination IP to the server but keeps the same source IP.

I think here it is referred to the two main architectures the ltm can be configured to (routed mode and SNAT mode).In routed mode you still have virtual servers for incoming traffic from the client destined for a VIP. Ltm changes the destination IP on the packet to point to the backend server, then transmits it. The client IP is maintained. We expect the return traffic from servers to hit the ltm. (Default gateway of servers set to ltm). Answer should be D.

In routing mode not translation occurs so B, it works as simple router (example is Forwarding VIP)
