It is more focused and doesn't hit the breadth of areas that the 270 covers which can get into sections of XP that you may only have cursory knowledge of. I know as dynamik mentioned that when I took the exam I went in really confident and after only 10 questions was sure that I was going to fail the exam. Fortunate for me I didn't do so bad.
