I’m preparing for the OpenShift administration exam (DO280/EX280), and I kept running into the same problem. Red Hat exams are fully hands-on, but most free practice material is either a static PDF or a quiz with no explanations. I wanted something that would run against a real cluster and tell me, objectively, whether the thing I built actually works. So I wrote one and published it: Red Hat Astronaut 2026 .

It is an independent practice tool. It is not affiliated with or endorsed by Red Hat. All questions are original material written to the published objectives. None of it is taken from, or claims to reproduce, real exam content.
