Actually, the "apply your knowledge" sort of questions basically test the same sort of knowledge as any of the other types of questions. For instance, in one of the sample questions from their Certification Success Guide, they give you a question where they give you a scenario, then ask:
"Which two
J2EE technologies should be used to handle HTTP requests?" The answer they give is
JSP and
servlets. Pretty obvious, even without their "scenario", eh?
Actually, those 10 example questions are good examples of the kinds of questions they give you. As a matter of fact, three of the questions I had on my exam were basically just rewordings from the sample questions! EJB stuff is underrepresented in the sample questions, though, I suppose because they wanted to give a more comprehensive sample, even if it included some things that they don't ask you too many times.
Have fun!
