What is the CKAD exam and how do I pass it?

CKAD (Certified Kubernetes Application Developer) is a 2-hour, hands-on, performance-based exam from the Cloud Native Computing Foundation (CNCF). You complete 15-20 practical tasks on a real Kubernetes cluster — designing, building, and deploying cloud-native applications. Passing score is 66%. ExamCert's free CKAD practice exam gives you realistic kubectl scenarios to prepare.

How much does the CKAD exam cost in 2026?

The CKAD exam costs $445 USD as of 2026, which includes one free retake. The Linux Foundation regularly runs 30-40% discount promotions during major events (KubeCon, Cyber Week). Bundle with CKA + CKS for additional savings.

How many questions are on the CKAD exam?

CKAD typically has 15-20 hands-on, performance-based tasks completed in 2 hours on a real Kubernetes cluster. It is NOT a multiple-choice exam — you actually run kubectl commands and write YAML manifests. ExamCert's free CKAD practice questions cover all of these task types.

What topics are covered on the CKAD exam?

CKAD exam domains: Application Design and Build (20%), Application Deployment (20%), Application Observability and Maintenance (15%), Application Environment, Configuration and Security (25%), Services and Networking (20%). Pods, Deployments, ConfigMaps, Secrets, Services, Jobs, CronJobs, NetworkPolicies, Probes, RBAC.

How long should I prepare for CKAD?

Most candidates need 6-10 weeks for CKAD preparation if they have basic Kubernetes experience, 3-4 months if starting from scratch. The exam is hands-on, so practice running kubectl commands until they are second nature. ExamCert recommends 200+ practice questions plus daily kubectl drills.

Is CKAD harder than CKA?

CKAD focuses on application developers — building, deploying, and maintaining cloud-native apps. CKA targets cluster administrators — installing, configuring, and troubleshooting the cluster itself. Most candidates find CKA broader (cluster lifecycle, etcd, networking internals) while CKAD is more focused but requires deeper YAML and kubectl fluency. Same difficulty level, different scope.

Is the CKAD certification worth it in 2026?

Yes. CKAD-certified engineers earn $130,000-$170,000 average salary in 2026. Kubernetes is the de facto container orchestrator across AWS EKS, Azure AKS, and GKE. The certification is vendor-neutral and recognized globally. Demand for Kubernetes skills grew 67% YoY in 2025.

📝 Sample Free CKAD Practice Questions

Sample questions from our free CKAD practice exam bank — modeled on the real performance-based format.

Question 1 — Multi-container Pod Patterns

You need a container that runs BEFORE the main application container to clone configuration files from a Git repo into a shared volume. After it finishes, the main container starts. Which Kubernetes construct should you use?

A. Sidecar container

B. Ambassador container

C. Init container

D. Adapter container

Question 2 — ConfigMaps & Secrets

You need to inject a database password into a pod so the application can read it as an environment variable named DB_PASS. Which is the MOST secure approach?

A. Hard-code the value in the Deployment YAML

B. Create a Secret and reference it via env.valueFrom.secretKeyRef

C. Create a ConfigMap and mount it as env vars

D. Pass it as a kubectl apply -- flag at runtime

Question 3 — Probes

A Java pod takes 45 seconds to start up before it can serve traffic. During that time, kubelet kills the container because the liveness probe fails. What is the BEST fix?

A. Add a startupProbe with appropriate failureThreshold × periodSeconds

B. Remove the liveness probe entirely

C. Increase the pod's CPU limit

D. Switch to a ReadinessProbe only

❓ Free CKAD Practice Exam — FAQ

Is CKAD multiple choice or hands-on?

CKAD is 100% hands-on, performance-based. You complete 15-20 real tasks on a live Kubernetes cluster — running kubectl commands, editing YAML, debugging pods. No multiple choice. ExamCert's free practice questions help you internalize the concepts before moving to live cluster drills.

Can I use kubectl autocomplete and aliases on the real CKAD exam?

Yes — kubectl autocomplete, aliases like k=kubectl, and the official kubernetes.io documentation are allowed and ENCOURAGED. Time is the biggest challenge on CKAD; practice using aliases and YAML generation with --dry-run=client -o yaml to save minutes.

Which Kubernetes version is the CKAD exam based on in 2026?

The CKAD exam is updated regularly. In 2026, the exam uses Kubernetes v1.31+. The CNCF posts exam version updates in the candidate handbook. Our practice questions are always updated to match the current exam version.
