I just took and passed the exam a few days ago. Here's what I did to prepare:
- Download the exam prep guide.
- Study each topic under "Skills Measured" section by finding answers in the Administrator Guide; give yourself an honest assessment of competency under each topic and then focus on the ones you're least comfortable with.
- Go through and practice some of the topics in a non-production environment.
It's a non-open book computerized exam with a mix of question types, i.e. T/F, pick the best answer(s), multiple choice. You can flag questions and good back during the exam.
Good luck and I hope to hear good news soon!
Thanks for the response John!
