Kubernetes CKA & CKAD Practice Exam

The Kubernetes CKA & CKAD Practice Exam is a free 20-minute skill test from Science of Apps. It tests readiness for the Kubernetes CKA and CKAD exams — cluster architecture and workloads, services and networking, storage and configuration, and troubleshooting and security — with kubectl scenarios like the performance-based exams. Score 70% or more on its 20 questions to earn a verifiable Kubernetes CKA & CKAD Readiness certificate (SOA-CKA). Every question is based on published standards and research — including Kubernetes concepts (kubernetes.io (CNCF)), kubectl reference (kubernetes.io (CNCF)), Certified Kubernetes Administrator (CKA) (The Linux Foundation) — and each answer is explained with its source.

Read the four skill areas on this page, then take the 20-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a Kubernetes CKA & CKAD Readiness certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: Kubernetes concepts (kubernetes.io (CNCF)); kubectl reference (kubernetes.io (CNCF)); Certified Kubernetes Administrator (CKA) (The Linux Foundation). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Cluster Architecture and Workloads (Control plane components, Deployments and scaling and Scheduling); Services and Networking (Service types, Ingress and DNS and Network policies); Storage and Configuration (Volumes and persistent storage, ConfigMaps and Secrets and Resources and probes); Troubleshooting and Security (Debugging pods and nodes, RBAC and service accounts and Cluster maintenance). Every question is an original scenario based on a published standard, official documentation or research, named under the question.

Kubernetes administrator, DevOps engineer, Platform engineer, Cloud-native developer and Site reliability engineer. It suits anyone who wants a quick, verifiable way to show CKA and CKAD skills, from students and career switchers to experienced professionals.

CKA (Certified Kubernetes Administrator) focuses on installing, configuring and troubleshooting clusters; CKAD (Certified Kubernetes Application Developer) focuses on designing, deploying and configuring applications on Kubernetes. Both are performance-based exams solved with kubectl in a live environment.

No. It is an independent practice test written to the publicly available CKA and CKAD content outline, for checking your readiness before you book the real exam. Science of Apps is not affiliated with The Linux Foundation and CNCF, and passing earns a Science of Apps certificate rather than the official credential.
