Free Certified Kubernetes Administrator practice test
10 real CKA questions, playable right now. No account, no card, no email gate. Every answer opens the full explanation: the concept, why the right option is right, and why each wrong option is wrong, cited to Linux Foundation / CNCF’s own documentation.
Sample question 1 of 10
A pod has been in Pending for ten minutes. kubectl describe pod ends with:
Warning FailedScheduling 0/3 nodes are available: 3 Insufficient memory.What is happening?
Sample question 2 of 10
Before editing a control plane manifest you copy it to kube-apiserver.yaml.backup inside /etc/kubernetes/manifests. What does the kubelet do with that backup file?
Sample question 3 of 10
A Service has no endpoints and traffic to it fails, although the pods are Running and Ready. What is the most likely cause?
Sample question 4 of 10
During peak traffic a container sits at its CPU limit. Response times climb and its restart count has not moved. What is the kernel doing to that container?
Sample question 5 of 10
A PersistentVolumeClaim stays Pending. The cluster has a PersistentVolume with enough capacity and a matching access mode. What else would prevent them binding?
Sample question 6 of 10
A pod has written roughly 40 MiB of output today, but kubectl logs returns far less than that on a cluster running kubelet defaults. What explains the shortfall?
Sample question 7 of 10
A control plane node lost power midway through kubeadm upgrade apply and the automatic rollback did not run. Where are the pre-upgrade static Pod manifests kept?
Sample question 8 of 10
You apply a default deny egress policy to a namespace. Every pod in it now fails outbound calls with Name or service not known. What must you add?
Sample question 9 of 10
You need a set of nodes reserved so that only pods that explicitly opt in may run there. Which mechanism does that?
Sample question 10 of 10
A PersistentVolumeClaim is deleted. Its bound PersistentVolume carries a Retain reclaim policy. What is the state of that volume afterwards?

What this test covers
These 10 questions are drawn across the published exam blueprint rather than from one chapter: this set touches Troubleshooting, Cluster Architecture, Installation and Configuration, Services and Networking, Workloads and Scheduling, Storage. Every question is original, written from the official objectives, and verified against a cited vendor page before it serves. None are recalled exam content, which is why the explanations can cite their sources.
A ten-question sample tells you where you stand, not whether you are ready. The full experience is numbered practice exams: 15 questions apportioned to the official domain weightings, sat under the real 120-minute clock and scored against the published cut score.
