Every Sun
Java exam (SCJP, SCWCD, SCBCD, and so on), has a large pool of questions from which different sets of exams are created. Sun makes every effort to assure that each exam set is well balanced from an objective perspective and that the different exams are as balanced in realtionship to each other as possible.
As far as looking at "real" questions is concerned, Sun understands that despite their security measures some people have managed to obtain copies of some of the "real" questions.
This practice is both illegal and immoral. It is cheating, pure and simple.
We can only hope that such cheaters will be caught either by Sun, or at the job interview, when it becomes evident that the cheater doesn't know his stuff. While it seems to me to be possilbe to use stolen papers to help you pass the exam, it's hard to see how cheating on the exam could help you in a job interview.
