CKA — Frequently Asked Questions

How many questions are on the real CKA exam?

The CKA is a performance-based exam with 15–20 tasks performed in a live Kubernetes environment. It is not multiple-choice — you must complete tasks on the command line within 2 hours. The pass mark is 66%. Our mock exam uses multiple-choice to test the same knowledge in a study format before you attempt the hands-on exam.

What Kubernetes version is the CKA exam based on?

The Linux Foundation updates the CKA exam regularly to track the latest stable Kubernetes minor release. Questions in this mock are aligned to Kubernetes 1.31 / 1.32 concepts. Always check the official Linux Foundation CKA page for the current exam version before booking.

Is kubectl allowed during the CKA exam?

Yes — the CKA is an open-book, hands-on exam. You have access to the Kubernetes documentation at docs.kubernetes.io and kubectl with tab completion in the exam terminal. Practising kubectl imperative commands (`run`, `expose`, `create`, `set image`, `rollout`) is essential for speed.

What are the most important CKA topics to study?

Focus on: kubeadm cluster setup and upgrades, etcd backup and restore, RBAC (Roles, RoleBindings, ClusterRoles), networking (Services, NetworkPolicy, DNS), workloads (Deployments, DaemonSets, StatefulSets, Jobs), storage (PV/PVC/StorageClass), and troubleshooting (CrashLoopBackOff, node NotReady, certificate expiry, DNS issues). Troubleshooting carries the most weight at 30%.

How is this mock exam different from the real CKA?

Our mock has 30 scenario-based multiple-choice questions per attempt (60 total across 2 exams) with a 60-minute timer. The real CKA has 15–20 hands-on performance tasks over 2 hours in a live cluster. The mock tests conceptual and diagnostic knowledge; the real exam tests execution. Use both together: understand concepts here, then practise kubectl tasks in a local cluster or killer.sh.
