Linux Foundation Certified Kubernetes Application Developer (CKAD) certification exam is a globally recognized certification program that validates the skills of Kubernetes application developers. The CKAD certification exam is designed to test the proficiency of developers in creating and deploying applications on Kubernetes clusters. It is one of the most sought-after certifications in the world of containerization and cloud-native computing.

Linux Foundation CKAD exam is ideal for developers who have experience with Kubernetes and want to demonstrate their mastery of the platform. It is also a great way for developers to gain a competitive edge in the job market, as more and more companies are adopting Kubernetes as their preferred platform for deploying and managing applications.

The CKAD Certification Exam is designed for developers with experience in containerization and Kubernetes, looking to validate their skills and knowledge to build, deploy, and manage cloud-native applications on Kubernetes. CKAD exam evaluates the candidate's understanding of Kubernetes architecture, Kubernetes objects, Kubernetes networking, Kubernetes storage, Kubernetes security, and Kubernetes troubleshooting. The CKAD certification is recognized globally by organizations and enterprises as a standard for Kubernetes application development expertise, making it a valuable credential for developers seeking to advance their careers in cloud computing and containerization.

Linux Foundation Certified Kubernetes Application Developer Exam Sample Questions (Q66-Q71):

NEW QUESTION # 66
You have a Deployment named 'web-app-deployments that runs a web application in a containerized environment. The application is designed for high availability and scalability, but you need to ensure that no more than two pods are ever terminated simultaneously during a rolling update process. This is to minimize the impact on service availability during the update. How would you implement this rolling update strategy using Deployment resources?

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
I). Update the Deployment YAML:
- Modify the 'strategy.roIIinglJpdate' section of the Deployment YAML to configure the rolling update behavior.
- Set 'maxunavailable: 1 ' to allow only one pod to be unavailable at a time during the update.
- Set 'maxSurge: 1 ' to permit only one additional pod to be created beyond the desired replica count during the update.

2. Apply the Updated Deployment: - Use ' kubectl apply -f web-app-deployment-yamr to update the Deployment. 3. Monitor the Rolling Update: - Observe the pod updates using 'kubectl get pods -I app=web-app' - You will see that during the rolling update, only one pod is terminated, while one new pod is created, ensuring that no more than two pods are ever terminated at the same time. 4. Verify the Update: - Once the rolling update is complete, check the 'updatedReplicaS field in the Deployment description Ckubectl describe deployment web-app- deployment) to verify that it matches the 'replicas' field.


NEW QUESTION # 67

Context
You are tasked to create a ConfigMap and consume the ConfigMap in a pod using a volume mount.
Task
Please complete the following:
* Create a ConfigMap named another-config containing the key/value pair: key4/value3
* start a pod named nginx-configmap containing a single container using the nginx image, and mount the key you just created into the pod under directory /also/a/path See the solution below.

Answer:

NEW QUESTION # 68
Exhibit:

Context
You are tasked to create a secret and consume the secret in a pod using environment variables as follow:
Task
* Create a secret named another-secret with a key/value pair; key1/value4
* Start an nginx pod named nginx-secret using container image nginx, and add an environment variable exposing the value of the secret key key 1, using COOL_VARIABLE as the name for the environment variable inside the pod

  • B. Solution:



Answer: A


NEW QUESTION # 69
You are deploying a microservice that handles image processing tasks. The service requires a significant amount of resources, including both CPU and memory. To optimize resource utilization and ensure efficient scaling, you want to leverage Kubernetes' resource management features. Design a deployment strategy that leverages Kubernetes resources to manage and optimize the image processing service.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:

2. Define Resource Requests and Limits: - Set resource requests and limits for your image processing containers- Requests define the minimum resources that each container needs to run smoothly, while limits define the maximum resources it can consume. This ensures that the service doesn't starve other workloads on the cluster and doesn't consume excessive resources. 3. Implement Horizontal Pod Autoscaling (HPA): - Configure HPA to automatically scale tne number of pods based on CPU or memory utilization. This enables the service to scale up during peak periods and scale down during low utilization to optimize resource usage. 4. Use Resource Quotas: - Implement Resource Quotas at the namespace level to limit the total resources that can be consumed by the image processing service and its associated workloads. This helps prevent resource starvation for other applications within the same namespace. 5. Utilize Node Affinity and Tolerations: - Apply node affinity and tolerations to schedule the image processing service on nodes that have the necessary resources (like GPLJs or high- performance CPUs) to efficiently handle image processing tasks- 6. Consider Using GPU Resources: - If your image processing tasks involve heavy computations, consider leveraging GPUs for accelerated processing. You can configure Kubernetes to schedule pods with GPU resources, ensuring that the image processing service nas access to tne necessary hardware for optimal performance.


NEW QUESTION # 70
You have a Deployment named 'wordpress-deployment' that runs 3 replicas of a WordPress container. You want to implement a blue- green deployment strategy for this deployment This strategy should involve creating a new replica set with the updated image, and then gradually shitting traffic to the new replica set. After the traffic has been shifted, the old replica set should be deleted. This process should be fully automated whenever a new image is pushed to the Docker Hub repository 'example/wordpress:latest'

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Kubernetes Secret for Docker Hub Credentials:
- You'll need a Secret to securely store your Docker Hub credentials for pulling images. Create a Secret with the following YAML:

- Replace with the base64 encoded content of your Docker Hub credentials file. This file is typically named '~/.docker/config.json' and contains your Docker Hub username and password. You can create this file or update it manually. To encode the file, use a command like 'base64 ~/.docker/config .jsons 2. Create a ConfigMap for Deployment Configuratiom - Create a ConfigMap to hold the image name and any other deployment-specific configuration:

3. Define a Deployment with a Blue-Green Strategy: - Create a Deployment named swordpress-deployment that incorporates the blue-green deployment strategy. This Deployment will have a 'strategy' section with a 'type' of 'Recreate' (for initial deployment) and a 'blueGreenDeploymentStrategy' section: 4. Create a Service.

- Create a Kubernetes Service that exposes your WordPress application. This service will automatically route traffic to the active replica set.

5. Automate the Blue-Green Deployment - Use a 'DeploymentConfig' resource to configure the automatic deployment

6. Apply the resources: - Apply all the YAML files using 'kubectl apply -f' to create the necessary resources. 7. Trigger the Blue-Green Deployment - Push a new image to the Docker Hub repository 'example/wordpress:latest' The 'Deploymentconfig' will automatically trigger the blue-green deployment: -A new replica set with the updated image will be created, and traffic will be shifted to the new replica set gradually - Once the traffic has been shifted, the old replica set will be deleted. Note: This implementation assumes that you are using OpenShift. If you are using a different Kubernetes distribution, the configuration may need to be adjusted SligntlY. ,
