So I'm doing Enthuware's simulator in Leitner mode. It seems like there are a lot of simulation questions on this area (WS-Addressing, WS-Policy, etc). Does the importance in the simulator accurately portray the importance on the exam? I can muddle through some, but I'm trying to assess if it's worth thoroughly learning this area compared to focusing on other areas.
Not everybody gets the same set of questions on the real exam. However you can expect at least one question in that line (WS-Policy, WS-Addressing). WSIT is a different story: not everything from the WSIT tutorial is being asked, but be sure you don't skip this.
