Cyber Security — Program 04
RHCSA — Red Hat System Administrator
RHCSA is a performance exam: no multiple choice, no essay. You are dropped onto broken systems and marked on whether they work at the end. Nobody passes it by memorising, which is exactly why employers trust it. We teach it the same way — after week one there are no slides, and every session ends with a machine someone has deliberately broken.
