Sample question 1 of 10

Troubleshooting

Four minutes after kubeadm init on a single node, the control plane is up and the namespace looks like this.

$ kubectl get pods -n kube-systemNAME                           READY   STATUS    RESTARTS   AGEcoredns-668d6bf9bc-4kx7t       0/1     Pending   0          4mcoredns-668d6bf9bc-p9x2s       0/1     Pending   0          4metcd-cp-1                      1/1     Running   0          4mkube-apiserver-cp-1            1/1     Running   0          4mkube-controller-manager-cp-1   1/1     Running   0          4mkube-scheduler-cp-1            1/1     Running   0          4m

What is the next step?

Sample question 2 of 10

Cluster Architecture, Installation and Configuration

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

Services and Networking

An engineer resolves the DNS name of a headless Service, which carries no cluster IP. What does that name resolve to?

Sample question 4 of 10

Workloads and Scheduling

An engineer notices that when a node goes NotReady its application Pods are evicted after five minutes, while the DaemonSet Pod on that node stays. Why?

Sample question 5 of 10

Storage

A 100Gi volume sits Available while the claim that should use it stays Pending.

$ kubectl get pv archive-01NAME         CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS      CLAIM   STORAGECLASS   AGEarchive-01   100Gi      RWO            Retain           Available           <unset>        6m $ kubectl get pvc archiveNAME      STATUS    VOLUME   CAPACITY   ACCESS MODES   STORAGECLASS   AGEarchive   Pending                                      standard       6m

Why do they not bind?

Sample question 6 of 10

Troubleshooting

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 7 of 10

Cluster Architecture, Installation and Configuration

A colleague reports that a SAN added to the kubeadm-config ConfigMap last month is still missing from the apiserver certificate after a renewal. Why?

Sample question 8 of 10

Services and Networking

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 9 of 10

Workloads and Scheduling

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 10 of 10

Storage

A PersistentVolumeClaim stays Pending. The cluster has a PersistentVolume with enough capacity and a matching access mode. What else would prevent them binding?

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 10-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.
