RH202 leads to the Red Hat Certified Technician certification. That means that you should focus on the installation and administration of a workstation machine. The practical exam does not focus on any specific topics. You should be familiar of all concepts that are taught in the course.
You must be familiar with _all_ of these topics:

However you should know that RHCT and RHCE exams are on the same day and configuration/troubleshooting is split to workstation and server topics.
So server topics that are focused on in RHCE and that are only a side note during the RHCT class, should be less important for your RHCT exam-
