Linux Foundation Certified Kubernetes Administrator (CKA) Program Sample Questions:
Question 1
Task Weight: 4%
Task
Schedule a Pod as follows:
* Name: kucc1
* App Containers: 2
* Container Name/Images:
o nginx
o consul
Question 2
Configure the kubelet systemd- managed service, on the node labelled with name=wk8s-node-1, to launch a pod containing a single container of Image httpd named webtool automatically. Any spec files required should be placed in the /etc/kubernetes/manifests directory on the node.
You can ssh to the appropriate node using:
[student@node-1] $ ssh wk8s-node-1
You can assume elevated privileges on the node with the following command:
[student@wk8s-node-1] $ | sudo -i
Question 3
You must connect to the correct host.
Failure to do so may result in a zero score.
[candidate@base] $ ssh Cka000047
Task
A MariaDB Deployment in the mariadb namespace has been deleted by mistake. Your task is to restore the Deployment ensuring data persistence. Follow these steps:
Create a PersistentVolumeClaim (PVC ) named mariadb in the mariadb namespace with the following specifications:
Access mode ReadWriteOnce
Storage 250Mi
You must use the existing retained PersistentVolume (PV ).
Failure to do so will result in a reduced score.
There is only one existing PersistentVolume .
Edit the MariaDB Deployment file located at ~/mariadb-deployment.yaml to use PVC you created in the previous step.
Apply the updated Deployment file to the cluster.
Ensure the MariaDB Deployment is running and stable.
Question 4
Score:7%
Task
Create a new PersistentVolumeClaim
* Name: pv-volume
* Class: csi-hostpath-sc
* Capacity: 10Mi
Create a new Pod which mounts the PersistentVolumeClaim as a volume:
* Name: web-server
* Image: nginx
* Mount path: /usr/share/nginx/html
Configure the new Pod to have ReadWriteOnce access on the volume.
Finally, using kubectl edit or kubectl patch expand the PersistentVolumeClaim to a capacity of 70Mi and record that change.
Question 5
Score: 4%
Task
Schedule a pod as follows:
* Name: nginx-kusc00401
* Image: nginx
* Node selector: disk=ssd
