CKAD exam is designed to test the practical skills of an individual in working with Kubernetes and its associated tools, rather than just their theoretical knowledge. Passing the CKAD exam is a valuable credential for developers who want to demonstrate their proficiency in developing cloud-native applications on Kubernetes, and it can open up new job opportunities and career advancement prospects.

CKAD certification is designed for software developers who have experience in container-based application development and want to validate their skills in Kubernetes application development. Additionally, system administrators, DevOps engineers, and IT professionals who work with Kubernetes can also take the certification to enhance their skills and knowledge.

Linux Foundation Certified Kubernetes Application Developer Exam Sample Questions (Q110-Q115):

NEW QUESTION # 110
You need to design a mufti-container Pod that includes a main application container and a sidecar container- The sidecar container should periodically check the health of the main application container using a health Check mechanism. If tne main application container iS unhealthy, the sidecar container should take corrective actions like restarting the main container or sending an alert. Explain how you can accomplish this using a sidecar container and health check probes.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define the Pod configuration: Create a Pod with two containers: the main application container and the sidecar container.

2. Configure the main application containers health check: Define a SlivenessPr0be' for the main container. This probe will periodically check the containers health using the specified mechanism. The probe will restart the container if it's unhealthy.

- specifies a TCP port to check. - 'initialDelaySeconds:' sets the delay before the first probe. - 'periodSeconds:' determines the frequency of health checks. - 'tailureThreshold:' specifies the number of consecutive tailed probes before restarting the container 3. Create the sidecar container: Design a sidecar container that monitors tne main containers health status. This container can be responsible for: - Observing health check results: Receive health check results from the main container. - Taking corrective actions: It the main container becomes unhealthy, the sidecar cam - Restart the main container: Use Kubernetes restart policy or 'execs commands to restart the main container. - Send alerts: Integrate with a monitoring system to send alerts about the main container's health issues. 4. Implement sidecar logic: Implement the necessary logic in the sidecar container to handle the health checks, perform corrective actions, and potentially interact witn a monitoring system. bash # Sidecar Dockerfile FROM ubuntu:latest # (add your monitoring and restart logic) # Start a process to periodically check main application container health CMD ["sh", "-c", "while true; do sleep 20; curl -s http://main-app:8080; exit 0; done"] 5. Test and monitor: Test the Pod's functionality by simulating a health issue in the main container. Ensure the sidecar container successfully identifies the issue and takes corrective actions. Monitor logs from both containers to validate the health check process and sidecar containers actions. This approach uses the sidecar container to monitor the health of the main application container, effectively managing the application's health and ensuring responsiveness to potential failures. ,

You are asked to prepare a Canary deployment for testing a new application release.
Task:
A Service named krill-Service in the goshark namespace points to 5 pod created by the Deployment named current-krill-deployment

1) Create an identical Deployment named canary-kill-deployment, in the same namespace.
2) Modify the Deployment so that:
-A maximum number of 10 pods run in the goshawk namespace.
-40% of the krill-service 's traffic goes to the canary-krill-deployment pod(s)

NEW QUESTION # 112
You are running a web application on Kubernetes, and you need to schedule a daily backup of your application's dat a. The backup process involves running a script that archives the database and uploads it to a remote storage service. Explain how you would implement this using a CronJ0b in Kubernetes. Provide a sample YAML configuration for the Cronjob.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Container Image:
- Create a Dockerfile that packages the backup script and any necessary dependencies into a container image-
- Build tne image and push it to a container registry (e.g., Docker Hub).
dockefflle
FROM ubuntu:latest
# Install necessary packages
RUN apt-get update && apt-get install -y zip
# Copy the backup script to the container
COPY backup.sh 'backup.sh
# Set entrypoint to the backup script
ENTRYPOINT ["/backup.sh"]
2. Create the CronJob YAML:
- Define the 'cronJob' resource in a YAML file. Specify the schedule, the container image, and the command to run.

3. Apply the CronJob: - Apply the YAML file to your Kubernetes cluster using 'kubectl apply -f cronjob.yamr 4. Verification: - Use 'kubectl get cronjobs' to check if the CronJob was successfully created- - Check the Kubernetes logs for the CronJob to ensure it's running as expected.

NEW QUESTION # 114
You have a statefulset named 'wordpress-statefulset' running a WordPress application, and you're experiencing intermittent issues with the database pod, causing intermittent downtime for the application. Describe the steps you would take to diagnose the issue, including any relevant Kubernetes commands or tools.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Check Pod Logs:
- Use ' kubectl logs -c database' to examine the logs of the database pod- Look for any error messages or warnings that might indicate the cause of the intermittent issues.
2. Check Resource Utilization:
- Use 'kubectl top pods -l app=wordpress-statefulset' to check the CPU and memory usage of the database pod. High resource utilization could indicate a resource constraint issue.
3. Inspect Pod Events:
- Use ' kubectl describe pod to view the events related to the database pod. Look for events like "Back-Off' or "Failed" which could indicate restart attempts or other issues.
4. Check Persistent Volume Claims:
- Use 'kubectl describe pvc to verify the status of the persistent volume claim used by the database pod. If the claim is in an error state, this could be a source of the issue.
5. Examine Node Status:
- Use ' kubectl describe node to check the status of the node where the database pod is running. If the node is experiencing issues or is under high load, it could affect pod stability
6. Check Network Connectivity:
- Verity network connectivity between the database pod and other pods in the statefulset. use tools like 'ping' or 'nc' to test connectivity.
7. Examine Database Configuration:
- If the database pod is using a database like MySQL or PostgreSQL, Check the database configuration files for any potential issues or settings that might be causing the intermittent problems.
8. Check Deployment Strategy:
- Ensure that the statefulset's deployment strategy is appropriate for the application. Consider using a rolling update strategy with a 'maxunavailable' setting to minimize downtime during updates.
9. Debug with Tools:
- Use tools like 'kubectl exec' or 'kubectl port-forward' to access the database pod and run debugging tools or commands directly inside the container. This allows for more in-depth analysis of the issue.
10. Consult Database Logs:
- If the database itself is experiencing issues, access the database logs from within the pod to get more detailed information on errors or performance problems. ,
