I just added a 20 questions practice exam for the 70-290 Managing and Maintaining a Microsoft Windows Server 2003 Environment exam.
You can find it on our 70-290 page here:
www.techexams.net/microsoft/70-290.shtml
Several questions are from the 70-292 MCSA/MCSE 2003 Upgrade exam (for people already certified as MCSA/MCSE on Windows 2000) as it covers partly exactly the same exam objectives as the 290 exam (and 291). 5 of the new 290 practice questions have been added to the 70-292 practice exam for the same reason.
You can find the 70-292 practice exam on this page:
www.techexams.net/microsoft/70-290.shtml
I'll add more soon until both are at least at 50 questions, and yes there will be an practice exam for the 291 exam as well. Just takes a while to write these lengthy Microsoft questions. (every 6 question with explanations equals one TechNotes in text...)
Happy reading
