Hi everyone, I've been studying/working in RH for a few months now for work, and I took the first admin course back in February. I've been meaning to take the exam in march/april, but that has been cancelled because of Covid. I haven't been working too much on studying because I did not know when I could take it, and my work on RH has been repetitive so its not really good practice for the exam.
I just checked for exam dates today, and found one posted one week from now. Is it possible to cram for it? I went through the O'Reilly RHCSA course once before, but honestly speaking I have not worked on all the practice questions. I can get some time off work and spend maybe 40-50 hours studying for it till next week.
Am I being too optimistic? My boss wants me to get certified ASAP and the next listing on the website is not available.
How would you cram? How much Linux sysadmin experience do you have? How confident are you in tackling scenarios involving the topics in the exam objectives ?
Will you have your nose in the book, highlighting commands, and files? If you do, then you will probably fail?
Here's how I practised for my EX200 exam:
There was no developers subscription  back then so I installed 2 CentOS VMs on my laptop. Because I didn't have the classroom/exam environment I had to learn to setup the infrastructure for services, and for clients. For example, if I wanted to setup and test the firewall for allowing ftp, then I need to setup a ftp server on vm1, configure the firewall there, and test it from vm2 (never test packet filter rules from the machine which will do the packet filtering - false positives are real). Same thing for NFS, timesync, etc.
I had to setup the server and client to practice, and in doing so, I learnt a lot.
I spent a lot of time setting up my infrastructure, breaking my infrastructure, and setting it up again. That time, was my exam practice because when I got to the exam, I had all this experience.
Time on the keyboard is of paramount importance when you attempt any Red Hat exams. Get your hands dirty.
