Hi All,
I have also cleared the Hadoop Developer as well as Administrator exam in first attempt and cloudera exam should not be taken light, because of its cost as well as level of the questions. Please find below whatever I had followed to prepare the exam. However, I want to clarify here that www.HadoopExam.com
do not ask any Microsoft (MS) keys for simulator. Once you install the trial version of their simulator on your computer, their software generate some unique key, which they need it to identify uniqueness of the machine to avoid any theft of the software and I don't see anything wrong with that.
I passed both CCAH & CCDH and here is what I did in that order.
1)www.HadoopExam.com Training Videos and Certification Simulator
Their Videos are very well designed for the core understanding of Hadoop Architecture. The lectures are very precise yet comprehensive, which cuts learning time significantly, besides providing a definite edge in certification exam and job interviews. Trainer did a great job in delivering the essential material in such a concise and effective manner that gives the learner very good foundation in Hadoop framework.
