Courseiva
This free CKAD practice test mirrors the structure and difficulty of the real Certified Kubernetes Application Developer CKAD 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 CKAD blueprint is divided into 5weighted 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 Application Environment, Configuration and Security and Application Design and Build contribute the most questions, meaning focused practice on these areas gives you the highest return on study time.
CKAD Exam Blueprint — 5 Domains
Application Design and Build
Application Deployment
Application Environment, Configuration and Security
Application Observability and Maintenance
Services and Networking
14 numbered sets, 5 domain question banks, and targeted sessions — every page is a unique set of questions.
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 CKAD on their first attempt:
Answer before revealing
Read each CKAD 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 CKAD 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 CKAD 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 CKAD on their first attempt report doing between 400 and 800 practice questions over 4–8 weeks of preparation. With 160+ questions in the Courseiva bank, you have more than enough material to build that repetition without seeing the same question twice.
Answer each question to reveal the full explanation and correct answer. This starter set is drawn from all 5 exam domains in blueprint proportion. Use the session selector to start a longer focused practice run.

A developer wants to expose a set of Pods on a specific port on each node's IP. Which Service type should be used?
Select an answer to reveal the explanation
You are responsible for a multi-tier application running in a Kubernetes cluster. The frontend Pods communicate with backend Pods via a Service named 'backend' in the same namespace. Recently, the frontend team reported that the backend Service is intermittently unreachable. You inspect the backend Pods and notice that they are all running and ready, but the Endpoints object for the 'backend' Service shows only a subset of the Pod IPs. You also notice that the backend Pods have a readiness probe configured that checks an HTTP endpoint '/healthz'. The readiness probe has a periodSeconds of 5 and failureThreshold of 3. The application logs show occasional spikes in response time on the /healthz endpoint, sometimes exceeding 15 seconds. You need to resolve the intermittent unavailability without removing the readiness probe. Which action should you take?

A structured study plan dramatically increases your chances of passing CKAD 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 CKAD preparation:
Cover each CKAD 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 CKAD score.
On exam day, the CKAD 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 CKAD exam is entirely performance-based — you deploy and manage applications in a live Kubernetes cluster using kubectl and YAML manifests. There are no multiple-choice questions. Courseiva practice questions cover the underlying concepts, but hands-on lab practice with Deployments, Services, ConfigMaps, and resource limits is still required.

Every question is written against the official CKAD 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 CKAD is a hands-on lab exam; these questions prepare your knowledge but hands-on practice is also required.
Most candidates who pass CKAD 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 CKAD covers 5 domains: Application Design and Build (20%), Application Deployment (20%), Application Environment, Configuration and Security (25%), Application Observability and Maintenance (15%), Services and Networking (20%). Each domain carries a different weight, so allocate your study time accordingly. The highest-weighted domains — Application Environment, Configuration and Security and Application Design and Build — 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 100% original — written by certified engineers to test the same knowledge areas using new scenarios and wording. You learn the material, not just the answers.
Per-domain analytics, spaced repetition, daily challenges — and every other certification on the platform.
