If the answer isn't port numbers, I'm going to throw my textbook out the window. That's how much I'm sure about this.

I'd go with port numbers, but I also accept bribes in the form of chocolate chip cookies. Just saying.

This is a trick question - the answer has to be port numbers. Unless the question is asking about layer 2, which would be just silly.

MAC addresses? Really? That's for layer 2, not layer 4. Port numbers are definitely the way to go here.

Subnet masks help determine which devices are on the same network, but they don't identify services like port numbers do.
