The CKA covers five hands-on domains, weighted most heavily toward troubleshooting (30%) and cluster architecture (25%). Everything is performance-based - you do real tasks, not multiple choice. Confirm current weights with CNCF.
| Domain | Weight | Note |
|---|---|---|
| Troubleshooting | 30% | Diagnose nodes, pods, networking and the control plane |
| Cluster Architecture, Installation & Configuration | 25% | RBAC, kubeadm, HA, etcd backup/restore |
| Services & Networking | 20% | Connectivity, services, ingress, network policies, CoreDNS |
| Workloads & Scheduling | 15% | Deployments, ConfigMaps/Secrets, scaling, scheduling |
| Storage | 10% | Storage classes, persistent volumes and claims |
How to study it
Because it is hands-on, study by doing in a real cluster, not by reading. Weight your time toward troubleshooting and cluster setup, and get fast with kubectl. Confirm the current curriculum with CNCF, since Kubernetes evolves.
