70-640 vs. 70-646
Which is better to do first? Is it better to understand Active Directory before even installing Server 2008?? I've read 646 somehow is harder than 640 and someone recommended going in order for the SA track (and probably for the EA track as well?). But, 646 describes the software itself starting with the installation and requirements. Wouldn't that make sense if you're not very familiar with either?
