Just took the 70-411 exam today and failed with 406/1000. Used MeasureUp Practice Questions and the 70-411 Training Guide by Orin Thomas. The practice tests was the definition of not useful and did not help with the exam at all. The book gave a good overview of topics but did not give enough information needed to pass for someone who does not have a huge server background. A tip for everyone who is coming from a desktop background, wait until the exam reference is released next year as well as some practice tests that have been tested and proven to help with the exam. This was the first exam I have ever failed by the way. I read the book twice and went through the entire suite of questions from MeasureUp 3 times. Probably spent about 2 months preparing.
Next Goal: Office 365 70-346 (Scheduled for 9/25)
