Ever since I received my MCDST for XP, I have done the upgrade path, for Vista, fairly easy, passed on 1st Try, Windows 7, not so easy. With the interaction of Windows 7 and Server 08 questions, it was a slight difficult for me, not that 70-621 did not have any of those questions, I guess maybe I had more time to study, then I do now. Since 70-689 will cover the two Windows 8 exams, 70-687/688, have anyone that have taken either one of these exams, noticed a focus on Server 2008 or 2012?? I am just curious, I am looking at take this exam toward the end of the year. I am currently working on 70-686, (2nd attempt, end of Jan 2013) The focus on 2008 Server Admin, then looking to take 70-417, and then 70-689. Any comments would be appreciated.
