To be fully prepared for the HDP Certified Administrator exam, candidates should be able to complete all of the exam objectives

Have you taken a look at that yet?

@Viswa

As per the exam objectives (https://hortonworks.com/services/training/certification/exam-objectives/#hdpca) there is no specific list of services which are in scope for the examination.

As far as debugging/monitoring the installation is concerned, you may refer to this official documentation:

http://docs.hortonworks.com/HDPDocuments/Ambari-2.0.0.0/Ambari_Doc_Suite/ADS_v200.html#ref-556d8737-67b1-43da-8331-bccb6ff28ac6

The above link lists generic steps on every aspect of installation right from stopping all services, selecting a service to install, configuring it, monitoring its progress. It also shows an output log snapshot & an error log snapshot from ambari-agent for the service you are trying to install.

The logs will list the error messages like what command failed or if the repo used is wrong etc.

You can derive hints from these logs to further your cause.

Hope this helps.
