Mark,
I took the exam a couple of weeks ago. It was HARD, no doubt about it. I didn't feel that any of the questions were missing information though. MS tried to create an exam that dealt with real world problems. Many of the questions required that you were able to recall information with being explicitly told. For example, if a question stated that the server was installed with "default values", you would have to know which network libs, character set, and sort order would be installed.
