Linux Foundation Certified Kubernetes Application Developer Exam Sample Questions (Q17-Q22):

NEW QUESTION # 17
You are building a microservice architecture for a new e-commerce application. This architecture consists of three microservices: 'product- service' , 'can-service' , and 'order-service'. Each microservice nas a dedicated database and utilizes a Redis cacne for performance optimization.
You are tasked with designing the 'product-service , which is responsible for managing product information (name, description, price, inventory).
Implement a multi-container Pod design for the product-service' that addresses the following requirements:
- The Pod must include a primary container running the 'product-service' application.
- The Pod must include a secondary container for Redis to cache frequently accessed product data.
- The Pod must use a shared volume to persist the Redis data across container restarts.
- The 'product-service' must connect to the local Redis instance in the Pod for optimized data retrieval.
- The product-service' should be configured to periodically update the Redis cache With the latest product data from the database.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create the Deployment YAML:
- Define a Deployment with the name 'product-service'
- Set the replicas to ' 2' to provide redundancy and high availability.
- Specify the labels Sapp: product-service' for selecting the Pods in the Deployment.
- Create a 'template' section to define the Pod specification.

2. Create the Persistent Volume Claim (PVC): - Define a PVC with the name 'redis-pvc' - Specify the storage class and access mode. - Set the required storage size for Redis data.

3. Deploy the Resources: - Apply the Deployment and PVC using 'kubectl apply -f deployment.yamr and 'kubectl apply -f pvc.yamr. 4. Verify the Deployment: - Check the status of the Deployment using 'kubectl get deployments product-service' and ensure that two Pods are running. - Check the status of the PVC using 'kubectl get pvc redis-pve 5. Configure the 'product-service'- - Modify the 'product-service' application to use the Redis instance in the Pod as the cache backend. - Configure the -product-service' to periodically tetch data trom the database and update the Redis cache. 6. Test the Application: - Send requests to the 'product-service to retrieve product data. - Monitor the Redis cache to ensure that it's being used and updated as expected. Important Considerations: - Ensure that the 'product-service' application is properly configured to connect to the Redis instance within the same Pod. - Use a suitable Redis cache library or framework in the 'product-service for efficient caching. - Implement a proper caching strategy (e.g., TTL, cache eviction) to prevent stale data. - Monitor the Redis cache performance and resource usage to optimize the cache configuration.


NEW QUESTION # 18
You have a Deployment named that runs 3 replicas of a Wordpress container. You need to implement a rolling update strategy that allows for a maximum or two pods to be unavailable at any given time during the update process. Additionally, you want to ensure that the update process is triggered automatically whenever a new image is pushed to the Docker Hub repository 'wordpress/wordpress:latest'.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. IJPdate the Deployment YAMLI
- Update the 'replicas to 2.
- Define 'maxunavailable: 2 and 'maxSurge: O' in the 'strategy.rollingupdate' section to control the rolling update process.
- Configure a 'strategy-type' to 'RollinglJpdate' to trigger a rolling update when the deployment is updated.
- Add a 'spec-template-spec-imagePullPolicy: Always" to ensure that the new image is pulled even if it exists in the pod's local cache.

2. Create the Deployment - Apply the updated YAML file using 'kubectl apply -f wordpress-deploymentyamr 3. Verify the Deployment: - Check the status of the deployment using 'kubectl get deployments wordpress-deployment to confirm the rollout and updated replica count. 4. Trigger the Automatic Update: - Push a new image to the 'wordpress/wordpress:latest' Docker Hub repository. 5. Monitor the Deployment: - Use 'kubectl get pods -l app=wordpress' to monitor the pod updates during the rolling update process. You will observe that two pods are terminated at a time, while two new pods with the updated image are created. 6. Check for Successful Update: - Once the deployment is complete, use 'kubectl describe deployment wordpress-deployment' to see that the 'updatedReplicas' field matches the 'replicas' field, indicating a successful update.


NEW QUESTION # 19

NEW QUESTION # 20
You are developing a container image for a .NET Core application tnat requires a specific version of tne .NET Core SDK to be installed. How would you ensure that the correct SDK version is available within your Docker image during the build process?

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
I). Choose .NET SDK Base Image:
- Select a base image that includes the desired .NET Core SDK version from Docker Hub.
- Example (for .NET core 3.1 SDK):
dockerfile
FROM mcr-microsoft.com/dotneVsdk:3.1
2. Copy Application Code:
- Copy your .NET Core application code into the Docker image.
- Example:
dockerfile
COPY
3. Build the Application:
- Use the 'RIJN' instruction to build your .NET Core application using the 'dotnet publish' command.
- Example:
dockerfile
RUN dotnet publish -c Release -o /app
4. Define Runtime Image (Optional):
- Create a second stage Dockerfile that uses a smaller base image, copying only the published application files.
- This optimizes the final image size.
- Example:
dockerfile
FROM mcr-microsoft.com/dotnet/aspnet:3.1
COPY -from=build /app /app
WORKDIR /app
ENTRYPOINT ["dotnet", "your-app.dll"]
5. Build and Deploy:
- Use 'docker build' to construct the final Docker image.
- Deploy this image to your Kubernetes cluster.


NEW QUESTION # 21
Context
Anytime a team needs to run a container on Kubernetes they will need to define a pod within which to run the container.
Task
Please complete the following:
* Create a YAML formatted pod manifest
/opt/KDPD00101/podl.yml to create a pod named app1 that runs a container named app1cont using image Ifccncf/arg-output
with these command line arguments: -lines 56 -F
* Create the pod with the kubect1 command using the YAML file created in the previous step
* When the pod is running display summary data about the pod in JSON format using the kubect1 command and redirect the output to a file named /opt/KDPD00101/out1.json
* All of the files you need to work with have been created, empty, for your convenience
