The exam went well, a 700 is need to pass and I achieved a 907; not too bad. Many of the questions covered the new features such as, Meeting Space, Windows Calendar, Defender and the beefed up Windows Firewall.
Interesting enough there were six simulations, some of which I went back and looked at for non-related questions, like firewall settings. They lock you into the various choices in the interface that one might use for the task; i.e. should you be in the Control Panel for a Windows Firewall question, you can't look at the Tablet PC Settings applet.
The testing site, A&A Computers, was acceptable and quiet, that is until a delivery person showed up in back and rang the bell incessantly. My exam also crashed while generating one of the simulations, I was an hour in at this point with 60% of the test completed. Luckily it saved all of my answers and picked up where I left off.
Now it's onto the 70-290 Windows 2003 Server exam. Why not Windows Server 2008? That down the road, but not far. But when you are a Microsoft Certified Trainer, you must pass the exams for the classes you want to teach, and I'm hoping to be as marketable as possible.
