A - Correct The capture shows the client requesting 207.206.201.100, but the pool member resides on a private address (192.168.200.10). Since the client cannot directly access the internal address, the LTM needs to translate the external request to the internal pool member's address. SNAT (Source Network Address Translation) changes the source IP address in the outgoing packet to an address the pool member can accept. This effectively "masks" the client's IP and allows communication.
