Linux Foundation Kubernetes and Cloud Native Associate Sample Questions (Q233-Q238):

NEW QUESTION # 233
Services and Pods in Kubernetes are ______ objects.

A. Java
B. REST
C. YAML
D. JSON

Answer: B

Explanation:
In Kubernetes, resources like Pods and Services are represented as API objects that you create, read, update, delete, and watch via the Kubernetes RESTful API. That makes D (REST) the correct answer.
Kubernetes is fundamentally API-driven: the API server exposes endpoints for each resource type (for example, /api/v1/namespaces/{ns}/pods and /api/v1/namespaces/{ns}/services). Clients such as kubectl, controllers, operators, and external systems interact with these resources by making REST-style calls using HTTP verbs (GET, POST, PUT/PATCH, DELETE) and using watch streams for event-driven updates. This API-first design is what enables Kubernetes' declarative model-users submit desired state to the API server, and controllers reconcile the cluster to that desired state.
Options A and B (JSON and YAML) are common serialization formats used to represent Kubernetes objects, but they are not what the objects "are." Kubernetes objects are logical API resources; they can be encoded as JSON (what the API uses) and often authored as YAML for human convenience. YAML is effectively a superset-friendly format that can be converted to JSON. The underlying API object model remains the same regardless of whether you wrote YAML or JSON. Option C (Java) is unrelated; Java is a programming language that can interact with Kubernetes via client libraries, but Kubernetes objects are not "Java objects" in the platform's definition.
So the accurate statement is: Pods and Services are Kubernetes REST API objects (resources) exposed and managed through the Kubernetes API server, which is why REST is the correct fill-in.

NEW QUESTION # 234
What framework allows developers to write code without worrying about the servers and operating systems they will run on?

A. Docker
B. Virtualization
C. Serverless
D. Kubernetes

Answer: C

NEW QUESTION # 235
You are running a resource-intensive application in Kubernetes. You want to reduce costs without impacting performance. Which of the following approaches would be most effective?

A. Optimize the application code to reduce resource consumption.
B. Decrease the number of replicas for the application's deployment.
C. Migrate the application to a different cloud provider with lower pricing.
D. Implement vertical pod autoscaling to adjust the resource allocation based on actual usage.
E. Reduce the resource requests and limits for the application's pods.

Answer: A,D

Explanation:
For resource-intensive applications, the most effective cost reduction strategies focus on optimizing resource usage and application efficiency. Vertical pod autoscaling (VPA) dynamically adjusts resource allocation based on actual usage, ensuring pods have sufficient resources without overprovisioning. Optimizing the application code itself to reduce resource consumption is crucial, as it can significantly impact overall cost. While decreasing replicas or reducing requests/limits might seem tempting, they can negatively impact performance. Migrating to a different cloud provider might offer cost advantages, but it's a complex and potentially disruptive process.

NEW QUESTION # 236
What kubectl command is used to retrieve the resource consumption (CPU and memory) for nodes or Pods?

A. kubectl version
B. kubectl api-resources
C. kubectl top
D. kubectl cluster-info

Answer: C

NEW QUESTION # 237
How does dynamic storage provisioning work?

A. A user requests dynamically provisioned storage by including an existing storage class in their PersistentVolumeClaim.
B. A pod requests dynamically provisioned storage by including a storage class and the pod name in their PersistentVolumeClaim.
C. An administrator creates a PersistentVolume and includes the name of the PersistentVolume in their pod YAML definition file.
D. An administrator creates a storage class and includes it in their pod YAML definition file without creating a PersistentVolumeClaim.

Answer: A

NEW QUESTION # 238
