Courseiva
This free CKS practice test mirrors the structure and difficulty of the real Certified Kubernetes Security Specialist CKS exam. Every question is written against the official 2026 exam blueprint published by CNCF, ensuring you practise exactly what the exam tests — not last year's objectives.
The CKS blueprint is divided into 6weighted domains. Questions on this page are distributed proportionally across each domain, so the mix you see here reflects the same weighting you'll face on exam day. High-weight domains like Minimize Microservice Vulnerabilities and Supply Chain Security contribute the most questions, meaning focused practice on these areas gives you the highest return on study time.

57 numbered sets, 6 domain question banks, and targeted sessions — every page is a unique set of questions.
Choose all correct answers
Each chapter page covers one topic in depth — theory, key concepts, and focused practice questions. Use these to close knowledge gaps before returning to full practice tests.
Getting the most from practice questions requires more than just clicking through answers. Here is the study method used by candidates who pass CKS on their first attempt:
Answer before revealing
Read each CKS question fully, eliminate obviously wrong choices, then commit to an answer before clicking to reveal. This active recall process is what builds lasting knowledge.
Read every explanation
Even when you answer correctly, read the full explanation. Knowing WHY the right answer is correct — and why the distractors are wrong — is what separates a 750 score from a 900 score.
Track weak domains
Note which CKS domains you get wrong most often. Then do a targeted 20-30 question session focused only on that domain until your accuracy improves.
Simulate exam pacing
The real CKS gives you roughly 7.5 minutes per question. Use the 60 or 120-question sessions to practise hitting that pace comfortably.
Most candidates who pass CKS on their first attempt report doing between 400 and 800 practice questions over 4–8 weeks of preparation. With 845+ questions in the Courseiva bank, you have more than enough material to build that repetition without seeing the same question twice.

A pod is stuck in Pending state. 'kubectl describe pod' shows the event: '0/4 nodes are available: 1 node had taint {node-role.kubernetes.io/control-plane: }, that the pod didn't tolerate, 3 Insufficient memory.' The pod YAML does not specify any tolerations. Which command would allow the pod to schedule on the control-plane node?

A developer reports that a pod cannot reach an external database at 192.168.1.100:3306. The pod's namespace is 'app'. You need to create a NetworkPolicy that allows egress to that IP only. Which policy is correct?

Which annotation is used to apply an AppArmor profile to a pod in Kubernetes?
Select an answer to reveal the explanation
A pod is scheduled on a node that has the AppArmor profile 'my-profile' loaded in complain mode. The pod annotation specifies 'localhost/my-profile' but the container is running without the profile being enforced. What is the most likely cause?

A pod in namespace 'ns1' has automountServiceAccountToken: false. However, the container still has a mounted service account token at /var/run/secrets/kubernetes.io/serviceaccount. What is the most likely cause?

A structured study plan dramatically increases your chances of passing CKS on the first attempt. The most effective approach combines reading the official CNCF documentation or a study guide, watching video explanations for difficult concepts, and then reinforcing everything with daily practice questions.
We recommend the following weekly structure for CKS preparation:
Cover each CKS domain systematically. Read the exam objectives, watch explanatory content, and do 10–20 practice questions per domain to test understanding as you go.
Run full 50–60 question mixed sessions daily. Review every wrong answer in detail. Identify which domains are consistently scoring below 70% and revisit those study materials.
Do 100–120 question timed sessions to simulate real exam conditions. Aim for consistent scores above 80% before booking your exam date. A score above 80% in practice typically translates to a passing CKS score.
On exam day, the CKS tests your ability to apply knowledge to realistic scenarios — not just recall definitions. This is why reading explanations and understanding the reasoning behind every answer matters more than simply grinding question volume. Use the high-count sessions (100, 120) in the final weeks as your confidence benchmark.
The real CKS exam is entirely performance-based — you harden, monitor, and secure a live Kubernetes cluster. There are no multiple-choice questions. Courseiva practice questions cover the security concepts tested, but hands-on lab practice with Pod Security Standards, RBAC, NetworkPolicies, and Falco is still required.

Every question is written against the official CKS exam objectives published by CNCF. They focus on the concepts and knowledge areas tested in the performance-based exam. These are original questions — not brain dumps — written to make you competent, not just exam-day lucky. Note that the real CKS is a hands-on lab exam; these questions prepare your knowledge but hands-on practice is also required.
Most candidates who pass CKS on their first attempt do 30–60 questions per day. Use the Quick 10 session for daily warm-ups when you are short on time. On study days, run a 50 or 60-question session to build stamina. Reserve 100 and 120-question sessions for the final two weeks when you want to simulate real exam conditions and benchmark your readiness.
The CKS covers 6 domains: Minimize Microservice Vulnerabilities (20%), Supply Chain Security (20%), Monitoring, Logging and Runtime Security (20%), System Hardening (10%), Cluster Setup (15%), Cluster Hardening (15%). Each domain carries a different weight, so allocate your study time accordingly. The highest-weighted domains — Minimize Microservice Vulnerabilities and Supply Chain Security — should receive the most attention.
Exam dumps are memorised question-and-answer lists taken from actual exam papers, often obtained illegally and shared without CNCF's authorisation. Using them violates your NDA and CNCF's certification agreement, and can result in certification revocation. Courseiva questions are original — AI-assisted, checked against the official exam objectives, and published under the editorial oversight of an engineer with 12+ years' experience. They test the same knowledge areas using new scenarios and wording. You learn the material, not just the answers.
