If you took the exam a few years ago, you will definitely need some study guides: a lot has changed in a few years. Braindumps, by the way, are not something that Red Hat endorses, unless they are on their own sites. Since this is the case, what you are asking for is illegal information - and that is against our rules. Therefore, this thread is closed.
Go get a study guide, go to Red Hat's website and read the syllabus and then get your employer to pay for training.
