Linux Foundation KCNA Exam Syllabus Topics:

TopicDetails
Topic 1
  • Cloud Native Observability: In this topic, telemetry and observability tools like Prometheus are examined, focusing on monitoring, logging, and diagnostics. Cost management strategies are also discussed, offering insights into optimizing resource usage. This equips the target audience to ensure the reliability and cost-efficiency of cloud-native applications, enhancing system performance and business value.
Topic 2
  • Kubernetes Fundamentals: In this topic, existing and aspiring developers, administrators, architects, and managers are introduced to foundational Kubernetes concepts, covering Kubernetes resources, architecture, and the Kubernetes API. The topic discusses the role of containers and their relationship to Kubernetes, emphasizing how scheduling works within the cluster.
Topic 3
  • Cloud Native Architecture: This section highlights autoscaling, serverless technologies, and the roles and personas that drive cloud-native innovation. It explores open standards, community involvement, and governance frameworks, enabling the target audience to design systems aligned with modern practices.
Topic 4
  • Container Orchestration: This topic delves into the principles of container orchestration, including runtime, security, and networking within Kubernetes clusters. The discussion extends to service mesh and storage solutions, enabling the audience to design and manage scalable, secure containerized workloads. Understanding these concepts prepares the target audience to navigate Kubernetes orchestration and enhance operational efficiency in cloud-native workflows.
Topic 5
  • Cloud Native Application Delivery: This section introduces the fundamentals of application delivery, emphasizing GitOps and CI
  • CD pipelines. It outlines strategies for deploying and managing cloud-native applications effectively. By mastering these concepts, the target audience learns to streamline delivery processes and adopt modern workflows for continuous integration and deployment in Kubernetes environments.

Linux Foundation Kubernetes and Cloud Native Associate Sample Questions (Q86-Q91):

NEW QUESTION # 86
Which Kubernetes resource provides standardized load balancing, TLS termination, and multi- context traffic routing across different implementations?

Answer: A

Explanation:
The Gateway API defines a standardized, extensible model for traffic management that includes load balancing, TLS termination, and advanced routing across different implementations, improving consistency compared to earlier approaches.


NEW QUESTION # 87
'kubectl delete -n my-ns po,svc --all' will delete pods and services including uninitialized ones in the namespace 'my-ns'

Answer: B

Explanation:
https://kubernetes.io/docs/reference/generated/kubectl/kubectl-commands#delete


NEW QUESTION # 88
In Kubernetes. which command is the most efficient way to check the progress of a Deployment rollout and confirm if it has completed successfully?

Answer: C

Explanation:
The kubectl rollout status command is specifically designed to monitor the progress of a Deployment rollout and report whether it is still in progress or has completed successfully.


NEW QUESTION # 89
Which item is a Kubernetes node component?

Answer: B

Explanation:
A Kubernetes node component is a component that runs on worker nodes to support Pods and node-level networking/operations. Among the options, kube-proxy is a node component, so C is correct.
kube-proxy runs on each node and implements parts of the Kubernetes Service networking model. It watches the API server for Service and endpoint updates and then programs node networking rules (iptables/IPVS, or equivalent) so traffic sent to a Service IP/port is forwarded to one of the backend Pod endpoints. This is essential for stable virtual IPs and load distribution across Pods.
Why the other options are not node components:
* kube-scheduler is a control plane component; it assigns Pods to nodes but does not run on every node as part of node functionality.
* kubectl is a client CLI tool used by humans/automation; it is not a cluster component.
* etcd is the control plane datastore; it stores cluster state and is not a per-node workload component.
Operationally, kube-proxy can be replaced by some modern CNI/eBPF dataplanes, but in classic Kubernetes architecture it remains the canonical node-level component for Service rule programming. Understanding which components are node vs control plane is key for troubleshooting: node issues involve kubelet/runtime
/kube-proxy/CNI; control plane issues involve API server/scheduler/controller-manager/etcd.
So, the verified node component in this list is kube-proxy (C).

NEW QUESTION # 90
A platform engineer is tasked with ensuring that an application can securely access the Kubernetes API without using a developer's personal credentials. What is the correct way to configure this?

Answer: C

Explanation:
Using a ServiceAccount and binding it to the Pod allows the application to authenticate to the Kubernetes API using a dedicated, non-personal identity with explicitly scoped permissions, following Kubernetes security best practices.
