I practiced a similar question, and I think B is right because packet filtering doesn't depend on the application layer.

I'm not entirely sure, but I feel like D might be the one that's incorrect since it sounds more like stateful filtering.

I'm a bit confused by some of these choices. Is there a specific order we need to prioritize them in? I'd probably go with A, B, and D to cover the main bases, but I'm not 100% sure.

Okay, I remember learning about COSO in class. They're the ones who developed the widely-used internal control framework, so D is definitely the right choice here.
