What should you study for the Certified Kubernetes Administrator exam?

To pass the Certified Kubernetes Administrator certification exam, you should focus on:

  • Cluster Architecture, Installation and Configuration: Covers installing and configuring Kubernetes clusters using kubeadm, managing RBAC, cluster upgrades, and etcd backup/restore.
  • Workloads and Scheduling: Covers deploying and managing Pods, Deployments, DaemonSets, StatefulSets, Jobs, CronJobs, and resource management.
  • Services and Networking: Covers Kubernetes networking, Service types, Ingress, NetworkPolicies, CoreDNS, and cluster DNS.
  • Storage: Covers Kubernetes persistent storage including PersistentVolumes, PersistentVolumeClaims, StorageClasses, and volume types.
  • Troubleshooting: Covers diagnosing and resolving issues with cluster components, node health, application failures, and network connectivity problems.

The exam tests your ability to apply concepts in real scenarios, not just memorize definitions.
