70-680, then 70-640 or 642?

Developing a cert program for career training, looking at 70-680, then 70-642 or 70-640. Users will have some experience, so which might be easier for relative newbies - 640 or 642? In other words, I know 680 should be first, but which should be next 642 or 640?

Thanks

The advise that I have seen is that study and take the 642 first. That way you get the exposure to DNS from 642, before taking on Active Directory in 640.
