Linux Foundation Certified Kubernetes Administrator (CKA) Program Exam Sample Questions (Q15-Q20):

NEW QUESTION # 15
You have a Deployment named 'frontend-deployment' with 5 replicas of a frontend container. You need to implement a rolling update strategy that allows for a maximum of 2 pods to be unavailable at any given time. You also want to ensure that the update process is completed within a specified timeout of 8 minutes. If the update fails to complete within the timeout, the deployment should revert to the previous version. Additionally, you want to configure a 'post-start' hook for the frontend container that executes a health check script to verify the application's readiness before it starts accepting traffic.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Update the Deployment YAML:
- Update the 'replicas' to 5.
- Define 'maxUnavailable: 2' and 'maxSurge: 0' in the 'strategy.rollingUpdate' section to control the rolling update process.
- Configure a 'strategy.type' to 'RollingUpdate' to trigger a rolling update when the deployment is updated.
- Set Always' to ensure that the new image is pulled even if
it exists in the pod's local cache.
- Add a 'spec.progressDeadlineSeconds: 480' to set a timeout of 8 minutes for the update process.
- Add a 'spec.template.spec.containers[0].lifecycle.postStart' hook to define a script that executes a health check script before the container starts accepting traffic.

2. Create the Deployment: - Apply the updated YAML file using 'kubectl apply -f frontend-deployment.yaml' 3. Verify the Deployment: - Check the status of the deployment using 'kubectl get deployments frontend-deployment' to confirm the rollout and updated replica count. 4. Trigger the Automatic Update: - Push a new image to the 'my.org/frontend:latest' Docker Hub repository. 5. Monitor the Deployment: - Use 'kubectl get pods -l app=frontend' to monitor the pod updates during the rolling update process. 6. Observe Rollback if Timeout Exceeds: - If the update process takes longer than 8 minutes to complete, the deployment will be rolled back to the previous version. This can be observed using 'kubectl describe deployment frontend-deployment' and checking the 'updatedReplicas' and 'availableReplicas' fields.,


NEW QUESTION # 16
You are tasked with configuring RBAC for a Kubernetes cluster hosting a microservices application.
The application consists of three services:
- 'frontend' which only needs to access the 'nginx-ingress-controller' deployment to configure Ingress resources.
- 'backend' which needs read-only access to the 'postgres' service for database queries.
- 'worker' which needs to create, update, and delete pods in the 'worker-namespace' namespace and access the 'redis' service.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Create the necessary RBAC roles, role bindings, and service accounts to enable these permissions.
Solution (Step by Step) :
1 . Create Service Accounts:
kubectl create serviceaccount frontend-sa -n default
kubectl create serviceaccount backend-sa -n default
kubectl create serviceaccount worker-sa -n worker-namespace
2. Create Roles:


3. Create Role Bindings: kubectl create rolebinding frontend-binding -n default -role=frontend-role serviceaccount=default:frontend-sa kubectl create rolebinding backend-binding -n default --role=backend-role - serviceaccount=default:backend-sa kubectl create rolebinding worker-binding -n worker-namespace -role=worker-role - serviceaccount=worker- namespace:worker-sa 4. Grant Access to Services: Frontend: The 'frontend' service account should have access to the 'nginx-ingress-controller' deployment. This can be done through a Role or ClusterRole and RoleBinding or ClusterRoleBinding, depending on if the controller is in the same namespace or across namespaces. Backend: The 'backend' service account should have read-only access to the postgres' service. This can be achieved by creating a 'ServiceAccount' for the 'backend' service and binding it to a 'Role' that grants the necessary permissions on the 'postgres' service. Worker: The 'worker' service account should have full access (create, update, delete) to pods in the 'worker- namespace' and read access to the 'redis' service. Important Notes: - The provided 'kubectl' commands are illustrative. You may need to adjust them based on your specific cluster configuration. - The above RBAC configuration is a basic example. Depending on the specific needs of your application, you may need to configure more granular roles and bindings.

NEW QUESTION # 18
Create a persistent volume with nameapp-data, of capacity2Giandaccess modeReadWriteMany. Thetype of volume ishostPathand itslocation is/srv/app-data.

Answer:

Explanation:
See the solution below.
Explanation
solution
Persistent Volume
A persistent volume is a piece of storage in aKubernetes cluster. PersistentVolumes are a cluster-level resource like nodes, which don't belong to any namespace. It is provisioned by the administrator and has a particular file size. This way, a developer deploying their app on Kubernetes need not knowthe underlying infrastructure.
When the developer needs a certain amount of persistent storage for their application, the system administrator configures the cluster so that they consume the PersistentVolume provisioned in an easy way.
Creating PersistentVolume
kind: PersistentVolumeapiVersion: v1metadata:name:app-dataspec:capacity: # defines the capacity of PV we are creatingstorage:2Gi#the amount of storage we are tying to claimaccessModes: # defines the rights of the volumewe are creating-ReadWriteManyhostPath:path: "/srv/app-data" # path to which we are creating the volume Challenge
* Create a Persistent Volume named ReadWriteMany, storage classname
shared,2Giof storage capacity and the host path

2. Save the file and create the persistent volume.

3. View the persistent volume.

* Our persistent volume status is available meaning it is available and it has not been mounted yet. This status willchange when we mount the persistentVolume to a persistentVolumeClaim.
PersistentVolumeClaim
In a real ecosystem, a system admin will create the PersistentVolume then a developer will create a PersistentVolumeClaim which will be referenced in a pod. A PersistentVolumeClaim is created by specifying the minimum size and the access mode they require from the persistentVolume.
Challenge
* Create a Persistent Volume Claim that requests the Persistent Volume we had created above. The claim should request 2Gi. Ensurethat the Persistent Volume Claim has the same storageClassName as the persistentVolume you had previously created.
kind: PersistentVolumeapiVersion: v1metadata:name:
spec:
accessModes:-ReadWriteManyresources:
requests:storage:2Gi
storageClassName:shared
2. Save and create the pvc
njerry191@cloudshell:~(extreme-clone-2654111)$ kubect1 create -f app-data.yaml persistentvolumeclaim/app-data created
3. View the pvc

4. Let's see what has changed in the pv we had initially created.
