Linux Foundation Kubernetes and Cloud Native Associate Sample Questions (Q77-Q82):

NEW QUESTION # 77
Your application requires specific network configurations for its pods, including custom DNS settings and network namespaces. How can you achieve this in Kubernetes?

A. Use a DaemonSet to deploy a network configuration agent on each node.
B. Configure a Pod's security context with specific network settings.
C. Modify the Kubernetes API server's network configuration settings.
D. Create a custom network plugin and integrate it with Kubernetes-
E. Use a NetworkPolicy to define custom network rules for the pods.

Answer: D

Explanation:
The correct answer is 'Create a custom network plugin and integrate it with Kubernetes'. Kubernetes allows you to extend its networking functionality by developing and integrating custom network plugins. These plugins can provide advanced network configurations, including custom DNS settings, network namespaces, and other specific network requirements. Options A, B, C, and E are not suitable for this scenario. 'NetworkPolicy' is used for network access control, 'Pod security context' defines security settings for a pod, 'DaemonSet' is used for deploying agents on nodes, and modifying the API server's network settings can affect the entire cluster's network configuration.

NEW QUESTION # 78
What is the purpose of the 'kubectl' command-line tool in Kubernetes?

A. Manages the Kubernetes API server and handles authentication and authorization requests.
B. Provides a command-line interface for interacting with and managing Kubernetes resources.
C. Enables communication between Pods and services within a Kubernetes cluster.
D. Provides a user interface for interacting with the Kubernetes cluster.
E. Schedules Pods to nodes and ensures that they are running as intended.

Answer: B

Explanation:
kubectl is a command-line tool that allows you to interact with and manage Kubernetes resources. It enables you to create, update, delete, and manage various Kubernetes objects such as Pods, Deployments, Services, and more.

NEW QUESTION # 79
You are deploying a web application with two containers: a frontend container for the website and a backend container for the application logic. What is the best practice for defining these containers within a Kubernetes pod?

A. Create two separate pods, one for the frontend and one for the backend.
B. Create a single pod with two containers, one for the frontend and one for the backend, connected through a shared volume.
C. Create a single pod with a single container running both the frontend and backend applications.
D. Create a single pod with two containers, one for the frontend and one for the backend, connected through a service.
E. Create a single pod with two containers, one for the frontend and one for the backend, connected through environment variables.

Answer: D

Explanation:
The best practice is to create a single pod with two containers, one for the frontend and one for the backend, connected through a service. This allows for efficient resource utilization, container isolation, and communication through the service. Option A might result in unnecessary complexity and resource usage- Option B would introduce tight coupling and lack of flexibility. Option C might lead to complexity in managing shared volumes. Option D, while possible, might be less efficient than using a service for communication.

NEW QUESTION # 80

C. Use a CI/CD pipeline to build and deploy the microservice directly to the cluster.
D. Store the desired state of your microservice (deployment configuration, service definition, etc.) in a Git repository and use a GitOps tool like Flux or ArgoCD to manage deployments.
E. Use a Kubernetes Operator to automate the deployment and management of your microservice.

Answer: D

Explanation:
GitOps emphasizes the use of Git as the single source of truth for managing your cluster's desired state. Option C correctly describes the GitOps approach by storing the configuration in a Git repository and using a GitOps tool to manage deployments, ensuring consistency and traceability.
