Guido van Brakel (@guidovbrakel) has posted the great “Preparation resources for the exam 70-417: Upgrading Your Skills to MCSA Windows Server 2012” on his blog http://www.enduria.eu some months ago.
Apparently he has now partnered up with the Microsoft Learning / Born To Learn team and is moderating wiki posts containing preparation resources for all kinds of exams including:
70-410: Installing and Configuring Windows Server 2012
70-411: Administering Windows Server 2012
70-412: Configuring Advanced Windows Server 2012 Services
70-413: Designing and Implementing a Server Infrastructure
70-414: Implementing an Advanced Server Infrastructure
From what I can see in the wiki based on the placeholders, a lot of great content is planned for the future as well.
PS: If you’re Dutch or Belgian, you might also want to take a look at the Tweakers.net forum and especially the “[Microsoft Certified] Ervaringen en discussies – Deel 9” thread where lots of Microsoft Certification information is shared.
