Learn the concepts. Pass the entry exam.

A KCSA practice lab: 310 multiple-choice questions mapped to the official curriculum, a learn mode that explains the reasoning behind every answer, a flashcard deck for rapid recall, and a timed 60-question mock exam with a practice target and per-domain feedback.

Two modes. Zero fluff.

The KCSA is multiple choice, so the preparation should be too: drill questions with instant explanations until the concepts stick, then sit a strict, timed replica of the exam format.

f.01 · learn

Explanations, not answer keys.

Every question ships a full rationale explaining the concept the question is testing, plus a link into the official docs. Wrong answers become the fastest way to learn.

per-answer why · docs links · instant feedback
f.02 · exam

A strict mock of the real format.

90 minutes, domain-weighted to the official curriculum, no feedback until you submit. Flag questions, jump around from the review sheet, and get a per-domain score report at the end.

90 minutes · 60 questions in our mock · pass at 75% in our mock
f.03 · progress

A readiness score that means something.

Your finished runs are saved to your account and rolled into a readiness score weighing recent performance, consistency, trend, and volume, the same formula our CKA/CKAD/CKS labs use.

attempt history · per-domain breakdown · readiness

Mapped to the official KCSA blueprint.

Domain weights mirror the published KCSA curriculum, and mock exams draw questions in those proportions, so your practice pressure lands exactly where the exam puts it.

What is the KCSA exam format?

The real KCSA is a 90-minute, online-proctored, multiple-choice exam covering six official domains. It is an entry-level security certification: conceptual, not performance-based, with no prerequisites. The Linux Foundation does not publish a question count or a pass mark for it, so our mock sets its own: 60 questions drawn in the official domain proportions, 90 minutes, pass at 75%.

Is this affiliated with the Linux Foundation or CNCF?

No. prepium.sh is an independent practice environment. The question bank is written against the published curriculum, not taken from a live exam. We are not the certifier, and the exam itself is purchased from the Linux Foundation separately.

How long should I study for the KCSA?

With some container experience, 1-3 weeks is typical. If Kubernetes is completely new, budget 4-6 weeks and lean on learn mode: the explanations are written to teach the concept, not just mark your answer. When your mock scores sit comfortably above 75%, you're ready.

Does the KCSA count toward Kubestronaut?

Yes. CNCF's Kubestronaut program requires holding all five Kubernetes certifications: KCSA, KCSA, CKA, CKAD, and CKS. KCSA is the usual first step. When you're ready for the hands-on exams, our CKA, CKAD, and CKS labs run on real clusters.

Are these real exam questions?

No, and that's deliberate. Every question is written against the official curriculum topics, not copied from a live exam. Memorizing leaked questions is both against the exam agreement and a bad way to actually learn; understanding the concepts behind 310 well-explained questions is what gets you through exam day.

KCSA passed? Go hands-on.

The next Kubernetes certifications are performance-based: real clusters, real tasks, real time pressure. That's exactly what the prepium.sh lab engine does.

310 questions. Every one explained.

Create a free account and try the sample, then unlock the bank and drill it in learn mode, then sit the 60-question mock under real time pressure. Your scores, per-domain breakdown, and readiness live on your account.
