Could you tell me why are you wanting dumps for clearing exams? off course you want to clear exam and don’t want to waste your money. Right?
If you learn Oracle database administration concept accurately then I don’t think you require dumps for passing out exams. If you do every practice which is mention in books then you would understand perfect concepts of every feature of Oracle. Without practicing anything you can not get. You should need to understand all features fundamentals. If anybody asks you any fundamental in technical interview then you won’t able to provide the accurate reply.
Thus remember one thing passing out only OCP exams is not sufficient for getting a good job. You need to have good understanding and knowledge of the subject.
