This now makes me an MCSA: Server 2008 (Microsoft Certified Solutions Associate) and also means I only have one more exam to complete to achieve the goal of becoming an MCITP Enterprise Administrator.
There were questions in my exam about:
RDS (quite a lot about RD Web Access and Remote Apps)
Streaming Media Services
FTP and SMTP services
Be familiar with command line, especially for IIS (appcmd) and WDS (wdsutil).
(The official list of 'Skills Measured' in the 70-643 exam can be found here
Training and resources used:
QA Training - 5 day instructor led course
MCTS Self-Paced Training Kit (70-643)
Just to think that last October I thought it would be near impossible to complete the final 3 exams by July 2013, I'm actually well on track for the MCITP EA. I'm even going to have a couple of weeks deserved rest before revision starts for the 70-647!
