Linux Foundation Kubernetes and Cloud Native Associate Sample Questions (Q175-Q180):

NEW QUESTION # 175
You are deploying a web application that requires a specific version of Node.js. How would you ensure that the correct Node.js version is installed on all nodes in your Kubernetes cluster?

A. Use a Dockerfile to include the specific Node.js version in the container image for the web application.
B. Install Node.js manually on each node before deploying the application.
C. Define a custom Kubernetes resource to manage Node.js installation across the cluster.
D. Use a Kubernetes init container to install Node.js before the main application container starts.
E. Use a Helm chart to manage the installation of Node.js on all nodes in the cluster.

Answer: A

Explanation:
The most effective way to ensure the correct Node.js version is used is to include it within the container image using a Dockerfile. By defining the Node.js version in the Dockerfile, you guarantee that every container built from that image will have the required version, eliminating dependency issues across nodes in your cluster. The container image becomes a self-contained unit, ensuring consistency and simplifying deployment.

NEW QUESTION # 176
How can persistent volume be provisioned?

A. Bootstrap
B. Dynamically
C. Automatically

Answer: B

NEW QUESTION # 177
You are using Kubernetes for deploying a microservices architecture. Each microservice has a unique configuration that needs to be injected into the container at runtime. Which approach is the most effective for managing these dynamic configuration changes?

A. Implementing a custom configuration management system outside of Kubernetes
B. Using environment variables during pod creation
C. Hardcoding configurations in the container image
D. Creating a separate ConfigMap for each service and mounting it as a volume
E. Using a service mesh to manage configuration and traffic routing

Answer: E

Explanation:
A service mesh like Istio provides a centralized and powerful approach to manage configuration changes, traffic routing, and other aspects of your microservices architecture. It simplifies dynamic configuration updates by allowing you to easily modify configurations for individual services without needing to update container images or restart pods.

NEW QUESTION # 178
You are using Prometheus to monitor a Kubernetes cluster. You want to set up an alert that triggers when the average CPU usage of all nodes in the cluster exceeds 80% for the last 10 minutes. Which Prometheus query can achieve this?

Answer: D

Explanation:
The query > 0.8' calculates the average system CPU usage across all nodes over the last 10 minutes. The filter ensures that only system CPU usage is considered. If the average exceeds 0.8 (80%), the alert will trigger.

NEW QUESTION # 179
You need to deploy a new version of your application to Kubernetes without causing any downtime or disruption to users. What open standard would you use to facilitate this process?

A. Kubernetes Rolling Update
B. Containerd
C. CloudEvents
D. Open Service Mesh (OSM)
E. Open Policy Agent (OPA)

Answer: A

Explanation:
Kubernetes Rolling Update allows you to deploy new versions of your application gradually- It replaces existing pods with the new version one by one, ensuring that there is always at least one pod running the previous version, minimizing downtime. This approach helps maintain the application's availability during updates-
