Based on the practice exam for HDPCA and comment from @William Gonzalez on one of my earlier question, in the actual exam we will have a minimally configured cluster, so we will not need to install from scratch on a base OS, but we will be required to configure different services as per the Objectives(http://hortonworks.com/training/certification/exam-objectives/#hdpca).
This forces me to wonder how the following objectives from 'Installation' category will be presented to us in the exam or will they not be a part of the exam since minimally configured cluster could already have these :
1. Configure a local HDP repository
2. Install ambari-server and ambari-agent
3. Install HDP using the Ambari install wizard
Thank you.
