Courseiva provides practice questions to reinforce the Certified Kubernetes Security Specialist CKS concepts tested in the real exam. The real CKS is hands-on and performance-based — these questions build the knowledge foundation for your lab preparation.
Performance-based exam
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.
Use these questions as a knowledge check
Answer each question, read the explanation carefully, and connect the concept back to the relevant lab task. These questions build the knowledge foundation for hands-on CKS lab practice.
This free CKS mock exam uses the same question distribution as the real Certified Kubernetes Security Specialist CKS exam. Each session draws questions proportionally from all 8 official blueprint domains published by CNCF, so the topic mix you see accurately reflects what you'll face on test day.
CKS Domain Distribution
Monitoring Logging and Runtime Security
Cluster Setup and Hardening
System Hardening
Minimize Microservice Vulnerabilities
Supply Chain Security
Monitoring, Logging and Runtime Security
Cluster Setup
Cluster Hardening
Every question is written by certified engineers against the 2026 CKS exam objectives. These are original practice questions — not dumps — so you build real understanding rather than memorising answers.
Both the mock exam and practice test use the same question bank. The difference is in how you use them — and when to use each during your CKS study plan.
Practice test — for learning
Use the CKS practice test when you are studying a domain. Answer questions, read every explanation immediately, and build understanding. Do 10–30 questions per domain per session. This is your primary study tool for the first 4 weeks.
Go to practice test →Concept review — for knowledge check
Use the CKS concept review sessions to benchmark your knowledge coverage across all topics. Work through a full question set, review every explanation, and use weak areas to guide your hands-on lab practice priorities.

A security team wants to detect anomalous process executions in containers without modifying the container images or requiring agents inside containers. Which approach is most suitable?

A cluster uses Kubernetes v1.24 with Pod Security Admission enabled. The cluster administrator wants to enforce that all pods in the 'production' namespace run with the 'restricted' policy level, but some existing deployments use privileged containers. Which approach ensures that only new pods violating the policy are rejected, while existing pods continue to run?

A security team is hardening a Kubernetes cluster. They need to ensure that all control plane components run with the least privilege. Which approach should they take?

A microservice running as a Deployment in a Kubernetes cluster needs to authenticate to a third-party API using a static API key. Which is the most secure way to store and inject this secret into the container?

A DevOps team wants to ensure that only signed images from a trusted registry are deployed in the cluster. They plan to use a webhook to intercept pod creation. Which tool is best suited for this task?

You are investigating a pod that is suspected of being compromised. You need to preserve the container's filesystem for forensic analysis. Which `crictl` command should you use to export the container's filesystem as a tar archive?

A team needs to set up a highly available Kubernetes control plane across three availability zones. What is the minimum number of etcd members required to achieve fault tolerance against one zone failure?

A security team wants to ensure that all pods in a namespace run with a restricted seccomp profile. Which Pod Security Standard admission controller mode should be used to enforce this without blocking necessary pods?

Answer all 8 questions to see your domain score breakdown
Passing CKS requires both conceptual understanding and hands-on competency. Use these questions to reinforce concepts, then immediately practise the corresponding lab tasks. Candidates who combine concept review with lab exercises pass at significantly higher rates.
Use these questions to confirm you understand the theory behind each CKS topic before attempting it in a lab. If you cannot explain why an answer is correct, revisit the concept before moving to the hands-on exercise.
After each concept question block, immediately run the equivalent command or configuration in a lab environment. Theory without practice does not pass performance-based exams.
Note which topics have low accuracy in these questions. Those are also the lab tasks most likely to trip you up. Prioritise additional hands-on practice in those areas.
The real CKS exam runs 120 minutes. During the exam, read each task description carefully, manage your time across tasks, and move on if stuck — come back rather than losing all remaining time.

Certified Kubernetes Security Specialist CKS is a performance-based exam. Your score is based on whether tasks are completed correctly in a live environment, not on multiple-choice answers. Strong concept coverage — tested through these questions — is one part of preparation. Hands-on lab practice is still required.
Yes. Courseiva provides free CKS mock exam questions across all official exam domains. The platform includes timed simulation, per-domain score breakdown, missed-question review, and readiness tracking. No account required — free forever, supported by advertising.
The practice test is optimised for learning: you see explanations after each question immediately. The mock exam is optimised for simulation: you answer all questions under time pressure and review at the end. Use practice tests for studying and mock exams for benchmarking.
These questions test your conceptual knowledge. Aim to fully understand every explanation before attempting the hands-on lab exam. High accuracy here indicates solid concept coverage, but hands-on lab practice is still required to pass CKS.
Most candidates preparing for CKS work through these concept questions multiple times while simultaneously doing hands-on lab exercises. Repeat topics where your accuracy is low, then confirm understanding with a lab exercise on the same topic.
No — all Courseiva questions are original, written by certified engineers against public CNCF exam blueprints. Exam dumps are memorised real exam questions shared illegally. Using dumps violates your CNCF certification agreement and can result in your certification being revoked. Our questions make you genuinely competent, not just test-day lucky.
