@Nikhil Vemula I took HDPCA certification exam last year, and I can tell you the key to pass this exam is practice and practice. Before the Exam ( time to get prepared) Take each subject from HDPCA and try to stress very possible scenarios. Hortonworks has a brilliant documentation use them in your preparation. (I used them in my preparation) By the way, you have a Practise exam available to check if you are prepared to take the exam. https://br.hortonworks.com/services/training/certification/hdpca-certification/ During the Exam - Read each question carefully. - You will have 2 hours to finish the exam, this is enough time to do it and still get to check it out. - If you find any questions that you do not know you can use the documentation that is available within the exam environment After the Exam Wait for your results.
