A couple of weeks ago, I passed the beta version of the two SharePoint 2010 IT Pro exams:
- Exam 70-668: PRO: Microsoft SharePoint 2010, Administrator
- Exam 70-667: MCTS: Microsoft SharePoint 2010, Configuring
Of course, I can’t tell you much about the actual content of the exam (NDA, you know…) but as long as there are no official “exam preparation guides”, I would recommend you to prepare for the exam by reading the Planning, Upgrade and Deployment guides for SharePoint 2010. The Technet site has a good overview of the downloadable content for SharePoint 2010.
