Hello, Dinesh, all good questions. You are correct that to "pass" the HDPCA exam you need to be at least familiar with the tasks in the Exam Objectives (http://hortonworks.com/training/certification/exam-objectives/#hdpca). The best way to prepare for the Exam is to run a Practice Exam on AWS (http://2xbbhjxc6wk3v21p62t8n4d4.wpengine.netdna-cdn.com/wp-content/uploads/2015/04/HDPCA-PracticeExamGuide.pdf). This practice environment has the same version as the exam will have and the tasks in practice are similar to the ones on the actual exam. In the actual exam you will have a minimally configured cluster, so you will not need to install from scratch on a base OS, but you will be required to configure different services as per the Objectives. If you still want to create a cluster from scratch, which is always a great thing to learn, you would probably want to install an HDP version that is close to the exam. The exam is based on the Hortonworks Data Platform 2.3 installed and managed with Ambari 2.1. Hope that this helps. ... View more
