Hello @SoorajT ! Not sure if I understood your query correctly - but there is no fixed number of times that you should reboot your system during any exams. It depends upon the exam objective and the candidate. The thing that is mandatory with Red Hat exams is that the configurations must persist reboot - so you figure about how many times you need to do that during an exam and how you would want to do that.
I can exaplain more. I am preparing for EX294 exam now. When I did EX200, all work done in node1 was not graded. When I created a ticket I got reply from Redhat saying after each exam nodes will be rebooted before grading and all my work done in node 1 was lost. So to avoid any situations like this I am asking this time reboot is required for EX294 nodes too as in EX200 ?If required how many times ? Will it be required reboot after each question to save configurations?
