Hold on, are we sure this is the right question? I thought we were supposed to be learning how to configure firewalls, not troubleshooting router ACLs. This is making my head spin!

Wait, why do we need to specify the interface when the ACL is already denying the traffic? Option C should be the correct answer.

Oh, I see. So option C would indeed prevent Host A and Host B from communicating.

True, but specifying the interface ensures the ACL is applied to the intended traffic path.

But the ACL is already denying the traffic, so why specify the interface?

But if the ACL is already denying the traffic, specifying the interface is redundant.

That makes sense. It adds an extra layer of security to prevent any misconfigurations.

I'm not sure, but I think option C might also work since it filters inbound traffic on a different interface.

I think Option B is the correct answer. Applying the ACL on the inbound interface of the other interface should work too.

Option A looks good to me. Blocking the traffic on the outbound interface should prevent Host A and Host B from communicating.
