I passed this exam on 7 March with 960/1000. The exam will heavily test MDT 2010 update 1, AIK, SCCM integration, Zero touch deployments, Office 2010 deployment and image engineering and a little Volume Activation.
Sadly there are no preparation materials listed on Microsoft’s exam but there are an infinite number of resources available to help pass this exam. I’m going to post a blog giving video links to each of the objectives, but for now here’s a few good places to get you started.
I’d also recommend posting any questions in the Microsoft Deployment Toolkit Forum.
