Certified Kubernetes Administrator (CKA) Prep
The Certified Kubernetes Administrator (CKA) is a hands-on, performance-based exam taken on a live cluster with kubectl. It spans five domains — cluster architecture, workloads and scheduling, services and networking, storage, and troubleshooting. Here's how it's structured — with realistic COSMIQ practice.
COSMIQ prepares you for the CKA (Kubernetes) and administers realistic full-length mock tests — it does not administer the real exam or issue the CKA certification.
Frequently asked
Is the CKA a hands-on exam?
Yes. It's performance-based: you complete roughly 15–20 tasks on a live Kubernetes cluster using kubectl within two hours, rather than answering multiple-choice questions.
What does the CKA cover?
Five domains: cluster architecture and configuration (25%), workloads and scheduling (15%), services and networking (20%), storage (10%), and troubleshooting (30%).
