Microsoft's certification website lists two prerequisites for 70-646. They are 70-640 and 70-642. Are these literal hard prereqs like you'd see in a school curriculum, or are they suggestions? IE: If I haven't take 70-640 or 642 can I take 70-646 or will I not even be able to register for it?
What you learn and are tested on in 70-646 builds upon what you learned in 70-640 and 70-642. You can take 70-646 first, but that's not really recommended since you really need to know the material on AD and Network Infrastructure.
