Layer 4? What is this, a trick question? Cisco Express Forwarding is all about moving packets from A to B, and that's definitely a Layer 3 thing. D is the way to go, no doubt about it.

Adjacency tables? That's just a fancy way of saying 'address book', right? I'm going with D, Layer 3, because that's where the magic happens.

I'm pretty sure Cisco Express Forwarding is all about Layer 3, so D has got to be the right answer. Unless they're trying to trick us with some fancy networking wizardry.
