Objective of CNCF CKA Certification Exam

The CNCF Certified Kubernetes Administrator exam tests knowledge on deploying, managing, and troubleshooting applications on Kubernetes clusters. Software engineers will need to understand key concepts of Kubernetes in order to pass the CNCF Certified Kubernetes Administrator exam. Files and containers running on the cluster will be managed by Kubernetes using its object-store. Understand key features of Kubernetes and how it is a paradigm shift in the way software engineers manage containerized applications. Learning about Kubernetes will be crucial for passing the CNCF Certified Kubernetes Administrator exam. Highly recommended to check out the official study guide. Technical manuals and practice questions can be found on the website. Functional knowledge of Kubernetes is crucial for passing the CNCF Certified Kubernetes Administrator exam.

Linux Foundation Certified Kubernetes Administrator (CKA) program is an industry-recognized certification that validates the skills and expertise of professionals in managing and deploying Kubernetes clusters. Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. As Kubernetes adoption continues to grow, the demand for certified professionals with the necessary skills and knowledge to manage Kubernetes clusters has also increased.

The CKA Exam is a hands-on, performance-based exam that tests the candidate's ability to perform tasks commonly required of Kubernetes administrators. It is designed to be challenging and requires a deep understanding of Kubernetes concepts, architecture, and deployment. CKA exam covers topics such as deploying and scaling applications, configuring networking, managing storage, and troubleshooting common issues. Passing the CKA exam demonstrates that the candidate has the skills and knowledge required to effectively manage Kubernetes clusters and is recognized as a valuable credential in the industry.

Linux Foundation Certified Kubernetes Administrator (CKA) Program Exam Sample Questions (Q60-Q65):

NEW QUESTION # 60
You have a Kubernetes cluster with a Deployment named 'web-app' running 3 replicas. One of the pods in the Deployment is consistently crashing, and you suspect it is due to resource limitations. You need to investigate the resource usage of the failing pod and adjust its resource requests and limits to prevent it from crashing.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Identify the Failing Pod:
- Use "kubectl get pods -l app=web-app' to list pods in the 'web-app' Deployment.
- Identify the pod that is consistently crashing. You might see an event in the pod's description like "Container
'web-app' exited with code 137" which indicates an OOMKilled event.
2. Examine Resource Usage:
- Get detailed information about the failing pod using 'kubectl describe pod '
- Look for the "Containers" section and pay attention to the resource usage metrics:
- CPU Usage: This will indicate how much CPU the container is using.
- Memory Usage: This shows how much memory the container is consuming.
- Resource Requests: This indicates how much CPU and memory the container is requesting.
- Resource Limits: This shows how much CPU and memory the container is allowed to use.
3. Adjust Resource Requests and Limits:
- Based on the resource usage and the "Resource Requests" and "Resource Limits" you observed in the previous step, increase the requests and limits for the container.
- Example: If the container consistently uses 200m CPU and 250Mi memory, increase the requests and limits to
250m CPU and 500Mi memory.
- Edit the Deployment YAML:

4. Update the Deployment: - Apply the updated YAML using 'kubectl apply -f web-app.yamP 5. Monitor the Pod: - Observe the pod's resource usage and stability after the update. - You can use 'kubectl describe pod ' or 'kubectl top pod to monitor resource usage. 6. Further Troubleshooting: - If the pod continues to crash, you might need to consider other factors, such as: - Container image optimizations: Ensure the container image is optimized for efficient resource consumption. - Application code adjustments: Analyze the application code for any resource-intensive operations. - Vertical Pod Autoscaling (VPA): Configure VPA to automatically adjust the resource requests and limits of pods based on their resource usage.


NEW QUESTION # 61
List the nginx pod with custom columns POD_NAME and POD_STATUS

Answer:

Explanation:
See the solution below.
Explanation
kubectl get po -o=custom-columns="POD_NAME:.metadata.name,
POD_STATUS:.status.containerStatuses[].state"


NEW QUESTION # 62
You have a Kubernetes cluster with two namespaces: 'dev' and 'prod'. You want to configure RBAC to allow developers in the 'dev' namespace to create deployments and pods, but only allow operations personnel in the 'prod' namespace to delete deployments and pods.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Create two RBAC roles and two role bindings to implement this configuration.
Solution (Step by Step) :
Step 1: Create a Role for Developers in the 'dev' namespace.

Step 2: Create a Role Binding for Developers in the 'dev' namespace.

Step 3: Create a Role for Operations Personnel in the 'prod' namespace.

Step 4: Create a Role Binding for Operations Personnel in the 'prod' namespace.

We define separate roles for developers and operations personnel, each with specific permissions in their respective namespaces. The roles specify which resources ('deployments', 'pods') can be accessed and which verbs ('create', 'delete', 'get') are allowed. Role bindings connect the roles to users, granting them the specified permissions. Applying the configurations: Use 'kubectl apply -f [filename].yaml' to apply the role and role binding YAML files. You can replace 'developer' and with actual user names or service account names.


NEW QUESTION # 63
Undo the deployment to the previous version 1.17.1 and verify Image has the previous version

Answer:

Explanation:
kubectl rollout undo deploy webapp kubectl describe deploy webapp | grep Image


NEW QUESTION # 64
A Deployment named 'my-app-deployment' is experiencing frequent crashes. You suspect that a specific container within the Deployment is causing the crashes. How would you use Kubernetes tools and techniques to isolate and debug the problematic container?

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Examine Pod Logs:
- Use "kubectl logs ' (where is the name of a crashing pod) to examine the logs from all containers within the pod. Look for error messages, unusual patterns, or indications of failing processes.
- Analyze the log messages carefully to identify which container is likely causing the crashes.
2. Investigate Pod Events:
- Use "kubectl describe pod ' to view the pod's events.
- Look for events that might indicate a specific container is crashing or encountering issues during startup. Events will include timestamps and reasons for the events.
3. Check Container Resource Limits:
- Use 'kubectl describe pod to check the resource requests and limits defined for each container within the pod.
- If the limits are too low, the containers might be being throttled or running out of resources, leading to crashes.
4. Use a Debugger:
- If you have access to the application code and a debugger (like a remote debugger in your development environment), you can attach to the problematic container to get more detailed information about its state and execution.
- Use the 'kubectl exec' command to access a container's shell, and then run the debugger.
5. Consider Health Checks:
- Ensure that the containers have proper health checks defined (e.g., liveness probes or readiness probes).
- Health checks can help Kubernetes identify failing containers and restart them or remove them from service.
6. Isolate the Container:
- If you suspect that the container itself is faulty, try isolating it by temporarily disabling the problematic container from the pod. You can do this by either:
- Removing the container from the Pod definition: Temporarily modify the Deployment to remove the problematic container.
- Stopping the container: Use 'kubectl exec' to access the pod's shell, and then stop the container.
7. Monitor and Repeat:
- After isolating the container, monitor the Deployment to see if the crashes stop.
- If the crashes are resolved, the isolated container was likely the cause. You can then focus on troubleshooting the container itself.
