Three of the 40 tasks in this pack
Question 1
Show the case study this question is based on
SIMULATION
Context
You have been asked to create a new ClusterRole for a deployment pipeline and bind it to a specific ServiceAccount scoped to a specific namespace.
Task
Create a new ClusterRole named deployment-clusterrole, which only allows to create the following resource types:
• Deployment
• Stateful Set
• DaemonSet
Create a new ServiceAccount named cicd-token in the existing namespace app-team1.
Bind the new ClusterRole deployment-clusterrole to the new ServiceAccount cicd-token, limited to the namespace app-team1.
Completed Answer
Create a ClusterRole with specific resource permissions, a ServiceAccount in a namespace, and bind them with a RoleBinding in that namespace.
Step 1 → kubectl config use-context k8s
Step 2 → kubectl create clusterrole deployment-clusterrole --verb=create --resource=Deployment,StatefulSet,DaemonSet
Step 3 → kubectl create sa cicd-token --namespace app-team1
Step 4 → kubectl create rolebinding deploy-b -n app-team1 --clusterrole=deployment-clusterrole --serviceaccount=app-team1:cicd-token
How To Work It Out
1. Switch to the k8s context so the commands run against the correct cluster.
2. Create the ClusterRole deployment-clusterrole with only the create verb on Deployment, StatefulSet and DaemonSet.
3. Create the ServiceAccount cicd-token in the app-team1 namespace.
4. Bind the ClusterRole with a RoleBinding named deploy-b created in app-team1, so the permissions apply only in that namespace.
A ClusterRole can be granted in two ways: a ClusterRoleBinding applies it in every namespace, while a RoleBinding applies it only in the namespace where the RoleBinding lives. Because the task limits the binding to app-team1, the RoleBinding is created with -n app-team1 and points at the ClusterRole and the app-team1:cicd-token ServiceAccount. The ServiceAccount can then create Deployments, StatefulSets and DaemonSets in app-team1 and nowhere else.

Question 2
SIMULATION
Task
Set the node named ek8s-node-0 as unavailable and reschedule all the pods running on it.
Completed Answer
Set the node named ek8s-node-0 as unavailable and reschedule all the pods running on it.
Step 1 → kubectl config use-context ek8s
Step 2 → kubectl get nodes
Step 3 → kubectl drain ek8s-node-0 --ignore-daemonsets --delete-emptydir-data
Step 4 → kubectl get nodes
How To Work It Out
1. Switch to the ek8s context.
2. List the nodes and find ek8s-node-0.
3. Drain ek8s-node-0 with --ignore-daemonsets and --delete-emptydir-data so it is cordoned and its pods are evicted.
4. Run kubectl get nodes to confirm ek8s-node-0 shows SchedulingDisabled.
kubectl drain first cordons the node, marking it unschedulable, and then evicts its pods so their controllers recreate them on other nodes. The node to drain is ek8s-node-0, the one the task names. --ignore-daemonsets lets the drain proceed past DaemonSet pods, and --delete-emptydir-data allows eviction of pods that use emptyDir storage.

Question 3
Show the case study this question is based on
SIMULATION
Task
The platform team publishes cluster components in an internal Helm chart repository. Use Helm to install the metrics gateway component as follows:
• Repository name: platform
• Repository URL: https://charts.example.internal/stable
• Chart: metrics-gateway
• Release name: gateway
• Namespace: observability (it does not exist yet and must be created by the installation)
• Value override: set the chart value replicaCount to 2 on the command line, without a values file
Verify that the release is deployed in the observability namespace and that the override is recorded for the release.
Completed Answer
Add the internal platform chart repository, install chart metrics-gateway as release gateway into the new namespace observability with replicaCount set to 2, and verify the release and its values.
Add the chart repository → helm repo add platform https://charts.example.internal/stable
Refresh the repository index → helm repo update
Install the release → helm install gateway platform/metrics-gateway --namespace observability --create-namespace --set replicaCount=2
Verify the release → helm list -n observability
Verify the override → helm get values gateway -n observability
Verify the Pods → kubectl get pods -n observability
How To Work It Out
1. Register the internal repository under the name platform with helm repo add, giving the name first and the URL second.
2. Run helm repo update so the local index lists the current version of the metrics-gateway chart.
3. Install release gateway from the chart reference platform/metrics-gateway, adding --namespace observability, --create-namespace because the namespace is missing, and --set replicaCount=2 for the override.
4. Run helm list -n observability and confirm that release gateway shows the status deployed.
5. Run helm get values for the release to confirm the user-supplied value replicaCount: 2, then list the Pods in observability to see the component start.
helm repo add stores the repository name and URL in the local Helm configuration, and helm repo update downloads its current chart index, so the reference platform/metrics-gateway resolves to the latest stable chart in that repository. helm install takes the release name first and the chart second. --namespace places the release and its objects in observability, and --create-namespace creates that namespace because it is not present. --set overrides one chart value on the command line, and Helm stores the override with the release, which is why helm get values shows replicaCount: 2. The same commands and flags work in Helm 3 and Helm 4.

What makes the CKA hard
There is no multiple choice, no definitions and no process of elimination. You get a live Kubernetes cluster, a terminal and a set of tasks: you either complete them or you do not.
15 to 20 tasks in 2 hours, 66% to pass. Knowing the commands is not enough; you need to execute them fast, verify your work and move on without hesitation. Most candidates who fail ran out of time, not knowledge, so speed with kubectl is really what the exam tests.
This pack has 40 real tasks for the CKA with complete step-by-step solutions, covering the exact formats the Linux Foundation uses, cluster troubleshooting, RBAC, network policies, storage and scheduling, plus the fastest way to solve each one.

It validates the ability to install, configure and manage production-grade Kubernetes clusters. It is fully hands-on, with no multiple choice, conducted in a live terminal environment. Valid for two years, with one free retake included per registration.
