Configuring NAT or IPSec doesn't seem relevant to the problem here. I think the key is to focus on the Windows firewall settings and logging.

I'm a little confused by the wording of the question. What exactly does "configure the solution" mean in this context? I'll need to think carefully about the differences between the answer choices.
