Linux Foundation Kubernetes and Cloud Native Associate KCNA Prüfungsfragen mit Lösungen (Q127-Q132):

127. Frage
A Pod is stuck in the CrashLoopBackOff state. Which is the correct way to troubleshoot this issue?

A. Use kubectl top pod <pod-name> to check CPU usage and then scale the Deployment to more replicas.
B. Use kubectl describe pod <pod-name> to review recent events and then kubectl logs <pod-name> to inspect container output.
C. Use kubectl get nodes to verify node capacity and then kubectl apply -f <pod.yaml> to restart the Pod.
D. Use kubectl exec <pod-name> -- bash to connect inside the container and then check system logs in /var
/log/kubelet.log.

Antwort: B

Begründung:
The CrashLoopBackOff state in Kubernetes indicates that a container inside a Pod is repeatedly starting, crashing, and then being restarted by the kubelet with increasing backoff delays. This is typically caused by application-level issues such as misconfiguration, missing environment variables, failed startup commands, application crashes, or incorrect container images. Proper troubleshooting focuses on identifying why the container is failing shortly after startup.
The most effective and recommended approach is to first use kubectl describe pod <pod-name>. This command provides detailed information about the Pod, including its current state, restart count, container statuses, and-most importantly-the Events section. Events often reveal critical clues such as image pull errors, failed health checks, permission issues, or failed command executions. These messages are generated by Kubernetes components and are essential for understanding the failure context.
After reviewing the events, the next step is to inspect the container's logs using kubectl logs <pod-name>.
Container logs typically capture application output written to standard output and standard error. For a crashing container, these logs often show stack traces, configuration errors, or explicit failure messages that explain why the process exited. If the container restarts too quickly, logs from the previous run can be retrieved using the --previous flag.
Option A is incorrect because kubectl exec usually fails when containers are repeatedly crashing, and /var/log
/kubelet.log is a node-level log not accessible from inside the container. Option C is incorrect because reapplying the Pod manifest does not address the underlying crash cause. Option D focuses on resource usage and scaling, which does not resolve application startup failures.
Therefore, the correct and verified answer is Option B, which aligns with Kubernetes documentation and best practices for diagnosing CrashLoopBackOff conditions.

128. Frage
You are managing a Kubernetes cluster with several nodes. You notice that one node is experiencing high CPU utilization due to a specific pod. How can you force this pod to be moved to a different node without deleting or restarting it?

A. Use the 'kubectl exec -it - bash' command to access the pod's shell and manually migrate the container to another node.
B. Use the 'kubectl delete pod ' command to delete the pod, causing it to reschedule on another node.
C. Use the 'kubectl cordon ' command to prevent new pods from being scheduled on the overloaded node.
D. Use the 'kubectl drain ' command to remove all pods from the node, allowing you to reschedule the specific pod.
E. Manually edit the pod's YAML configuration and change the 'nodeName' field to a different node in the cluster

Antwort: D

Begründung:
The 'kubectl drain ' command is used to gracefully remove all pods from a node, preparing it for maintenance or eviction. The command will not delete the pods, allowing them to be rescheduled on other nodes. This allows you to move the pod without deleting or restarting it. Option A deletes the pod, which is not what the question asks for. Options B and C are not possible or recommended actions for pod migration. Option D prevents new pods from scheduling on the overloaded node but won't force the pod to move.

129. Frage
In distributed system tracing, is the term used to refer to a request as it passes through a single com-ponent of the distributed system?

A. Log
B. Bucket
C. Span
D. Trace

Antwort: C

130. Frage
What is the role of a NetworkPolicy in Kubernetes?

A. The ability to cryptic and obscure all traffic.
B. The ability to classify the Pods as isolated and non isolated.
C. The ability to prevent loopback or incoming host traffic.
D. The ability to log network security events.

Antwort: B

Begründung:
A Kubernetes NetworkPolicy defines which traffic is allowed to and from Pods by selecting Pods and specifying ingress/egress rules. A key conceptual effect is that it can make Pods "isolated" (default deny except what is allowed) versus "non-isolated" (default allow). This aligns best with option B, so B is correct.
By default, Kubernetes networking is permissive: Pods can typically talk to any other Pod. When you apply a NetworkPolicy that selects a set of Pods, those selected Pods become "isolated" for the direction(s) covered by the policy (ingress and/or egress). That means only traffic explicitly allowed by the policy is permitted; everything else is denied (again, for the selected Pods and direction). This classification concept-isolated vs non-isolated-is a common way the Kubernetes documentation explains NetworkPolicy behavior.
Option A is incorrect: NetworkPolicy does not encrypt ("cryptic and obscure") traffic. Encryption is typically handled by mTLS via a service mesh or application-layer TLS. Option C is not the primary role; loopback and host traffic handling depend on the network plugin and node configuration, and NetworkPolicy is not a "prevent loopback" mechanism. Option D is incorrect because NetworkPolicy is not a logging system; while some CNIs can produce logs about policy decisions, logging is not NetworkPolicy's role in the API.
One critical Kubernetes detail: NetworkPolicy enforcement is performed by the CNI/network plugin. If your CNI doesn't implement NetworkPolicy, creating these objects won't change runtime traffic. In CNIs that do support it, NetworkPolicy becomes a foundational security primitive for segmentation and least privilege: restricting database access to app Pods only, isolating namespaces, and reducing lateral movement risk.
So, in the language of the provided answers, NetworkPolicy's role is best captured as the ability to classify Pods into isolated/non-isolated by applying traffic-allow rules-option B.

131. Frage
Which of the following options include resources cleaned by the Kubernetes garbage collection mechanism?

A. Nodes deleted by a cloud controller manager and obsolete logs from the kubelet.
B. Stale or expired CertificateSigningRequests (CSRs) and old deployments.
C. Terminated pods, completed jobs, and objects without owner references.
D. Unused container and container images, and obsolete logs from the kubelet.

Antwort: C

Begründung:
Kubernetes garbage collection (GC) is about cleaning up API objects and related resources that are no longer needed, so the correct answer is D. Two big categories it targets are (1) objects that have finished their lifecycle (like terminated Pods and completed Jobs, depending on controllers and TTL policies), and (2)
"dangling" objects that are no longer referenced properly-often described as objects without owner references (or where owners are gone), which can happen when a higher-level controller is deleted or when dependent resources are left behind.
A key Kubernetes concept here is OwnerReferences: many resources are created "owned" by a controller (e.
g., a ReplicaSet owned by a Deployment, Pods owned by a ReplicaSet). When an owning object is deleted, Kubernetes' garbage collector can remove dependent objects based on deletion propagation policies (foreground/background/orphan). This prevents resource leaks and keeps the cluster tidy and performant.
The other options are incorrect because they refer to cleanup tasks outside Kubernetes GC's scope. Kubelet logs (B/C) are node-level files and log rotation is handled by node/runtime configuration, not the Kubernetes garbage collector. Unused container images (C) are managed by the container runtime's image GC and kubelet disk pressure management, not the Kubernetes API GC. Nodes deleted by a cloud controller (B) aren' t "garbage collected" in the same sense; node lifecycle is handled by controllers and cloud integrations, but not as a generic GC cleanup category like ownerRef-based object deletion.
So, when the question asks specifically about "resources cleaned by Kubernetes garbage collection," it's pointing to Kubernetes object lifecycle cleanup: terminated Pods, completed Jobs, and orphaned objects- exactly what option D states.
