Practice on real systems, graded by the system itself.
Prepium is an independent practice platform for 8 IT certifications: CKA, CKAD, CKS, RHCSA, KCNA, KCSA, Fortinet NSE4 and CompTIA Security+. It exists for one reason: performance-based exams are passed at the keyboard, so you should practise at the keyboard, on real systems, against a clock.
Who builds Prepium
Prepium is built and maintained by a Kubestronaut: an engineer who holds all five CNCF Kubernetes certifications (CKA, CKAD, CKS, KCNA and KCSA) and has sat those exams under the same conditions you are preparing for. Every Kubernetes lab task is solved end to end and regression-tested by that same engineer before it ships.
Prepium is not affiliated with, endorsed by, or sponsored by the Linux Foundation, the Cloud Native Computing Foundation, Red Hat, Fortinet or CompTIA. Certification names are trademarks of their owners and are used here only to describe what each practice track prepares you for.
How the practice works
- Real environments. Kubernetes tasks run on real clusters created for you alone, reached through a Linux desktop in your browser. RHCSA tasks run on real virtual machines. Nothing is a simulated terminal.
- Graded by inspecting state. When you finish, validation scripts inspect the actual cluster or machine: the objects that exist, their configuration, and whether they work. You get per-check results, so you know exactly which requirement you missed.
- Exam-style timing. Full mock exams run against the clock with task navigation and review flags. Single-task practice lets you drill one weakness at a time.
- Question banks with explanations. KCNA, KCSA, NSE4 and Security+ are multiple-choice exams, so those tracks are question banks with explanations, timed mocks and per-domain readiness tracking.
- AI Lab Coach. In single-task labs, the coach can review your commands, saved files and lab state to explain what to fix. It is a study aid; your score always comes from the validation scripts.
