Linux Foundation Certified Kubernetes Application Developer Exam Sample Questions (Q119-Q124):

NEW QUESTION # 119
Context

Task:
Create a Deployment named expose in the existing ckad00014 namespace running 6 replicas of a Pod. Specify a single container using the ifccncf/nginx: 1.13.7 image Add an environment variable named NGINX_PORT with the value 8001 to the container then expose port 8001

Answer:

Explanation:
Solution:



NEW QUESTION # 120
You are running a multi-tier application in Kubernetes. Your application consists of a frontend service (nginx) and a backend service (app). The frontend service exposes a port to the outside world, while the backend service listens on a different port. The backend service needs to access a database service running on a different node.
You need to create a network policy that allows the nginx service to access the app service, and the app service to access the database service. Ensure tnat no otner traffic is allowed between pods in the cluster.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define Network Policy for Nginx Service:
- Create a NetworkPoliCY named 'nginx-policy' that allows traffic from pods labeled 'app=nginx' to pods labeled Sapp-apps
- Use 'ingress' rules to define incoming traffic to the nginx service-
- Specify the for the nginx service.
- Allow all ports.

2. Define Network Policy for App Service: - Create a NetworkP01iCY named 'app-policy' that allows traffic from pods labeled 'app=app' to pods labeled 'app=database' - Use 'ingress' rules to define incoming traffic to the app service. - Specify the 'podSeIector' for the app service. - Allow traffic on the port that the database service listens on.

3. Create the NetworkPolicy Objects - Apply the NetworkP01iCies using the 'kubectl apply' command: bash kubectl apply -f nginx-policy.yaml kubectl apply -f app-policy.yaml 4. Apply Default Network Policy: - Create a NetworkPoliCY named 'default-policy' that blocks all traffic by default. - This ensures that only traffic allowed by the specific policies is permitted.

5. Apply Default Network Policy: - Apply the NetworkPoliCY using the 'kubectl apply' command: bash kubectl apply -f default-policy_yaml This configuration ensures that: - Nginx Service: Can access the 'app' service on port 80, and no other traffic is allowed in or out. - App Service: Can access the 'database' service on port 5432, and no other traffic is allowed in or out - All Other Pods: All other pods in the cluster are blocked from communicating with each other by the default network policy.,


NEW QUESTION # 121
You have a Deployment for a stateless application that involves several containers. You want to expose this application as a single service using a Service resource- You also want to configure the Service to use a specific label selector to target the correct pods and to ensure that the Service uses a round-robin load balancing strategy for distributing traffic across the pods. Explain how you can create the Service resource and configure it to acnjeve this.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Service:
- Create a Service resource that defines how the pods of your application will be accessed externallv
- Specify a unique name for the Service and define the port mapping-
- Example:

2. Set Selector: - Use the 'selector field to specify the label that the Service should use to identify the pods it should target - Ensure that the pods of your Deployment are labeled with the specified 'app: myapp' label. 3. Configure Load Balancing: - The default load balancing strategy for Kubernetes Services is round-robin, which distributes traffic evenly across the available pods. - No additional configuration is needed for this strategyc 4. Deploy and Test: - Apply the Service YAML file. - Test the Service by accessing it from outside the cluster. - Ensure that the traffic is distributed evenly across the pods using the round-robin strategy. 5. Optional: External Access: - If you want to expose the Service to the internet, you can set the Service 'type' to 'Load8alancer'. This will create a LoadBalancer resource (often an external IP address) that routes traffic to the Service.


NEW QUESTION # 122
You are running a critical application in Kubernetes tnat requires nign availability and IOW latency. The application uses a statefulset With 3 replicas, each consuming a large amount of memory. You need to define resource requests and limits for the pods to ensure that the application operates smoothly and doesn't get evicted due to resource constraints.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Determine Resource Requirements:
- Analyze tne application's memory usage. Determine tne average memory consumption per pod and the peak memory usage.
- Consider the resources available on your Kubernetes nodes.
- Define realistic requests and limits based on the application's needs and available node resources.
2. Define Resource Requests and Limits in the StatefuISet:
- Update the StatefuISet YAML configuration with resource requests and limits for the container.
- requests: Specifies the minimum amount of resources the pod will request
- limits: Specifies the maximum amount of resources the pod can use.

3. Apply the StatefulSet Configuration: - Apply the updated StatefulSet configuration to your Kubernetes cluster: bash kubectl apply -f my-critical-app-statefulset.yaml 4. Monitor Resource Usage: - Use 'kubectl describe pod' to monitor the resource usage of the pods. - Ensure that the pods are utilizing the requested resources and not exceeding the limits.


NEW QUESTION # 123
You are developing a new microservice that requires access to a database deployed in a different namespace. You want to configure a ServiceAccount and RoleBinding to provide the necessary permissions for the microservice to connect to the database.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a ServiceAccount:
- Create a ServiceAccount in the namespace where our microservice is deployed:

2. Create a Role: - Create a Role in the namespace where the database is deployed, granting access to the database resources:

3. Create a ROIeBinding: - Create a RoleBinding in the database namespace to bind the Role to the ServiceAccount:

4. Apply the Configuration: - Apply the created ServiceAccount, Role, and Roledinding using 'kubectl apply -r commands: bash kubectl apply -f my-microservice-sa_yaml kubectl apply -f my-database-access-role-yaml kubectl apply -f my-database-access-rolebinding.yaml 5. Configure the Microservice: - Mount the ServiceAccount token as a secret within the microservice's pod:

6. Verify Permissions: - Access the database from the microservice pod to verify that the required permissions are granted.
