CKAD Linux Foundation Certified Kubernetes Application Developer (CKAD) Program Free Practice Exam Questions (2025 Updated)

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

Context

You have been tasked with scaling an existing deployment for availability, and creating a service to expose the deployment within your infrastructure.

Task

Start with the deployment named kdsn00101-deployment which has already been deployed to the namespace kdsn00101 . Edit it to:

• Add the func=webFrontEnd key/value label to the pod template metadata to identify the pod for the service definition

• Have 4 replicas

Next, create ana deploy in namespace kdsn00l01 a service that accomplishes the following:

• Exposes the service on TCP port 8080

• is mapped to me pods defined by the specification of kdsn00l01-deployment

• Is of type NodePort

• Has a name of cherry

Task:

1- Update the Propertunel scaling configuration of the Deployment web1 in the ckad00015 namespace setting maxSurge to 2 and maxUnavailable to 59

2- Update the web1 Deployment to use version tag 1.13.7 for the Ifconf/nginx container image.

3- Perform a rollback of the web1 Deployment to its previous version

Set Configuration Context:

[student@node-1] $ | kubectl

Config use-context k8s

Context

A pod is running on the cluster but it is not responding.

Task

The desired behavior is to have Kubemetes restart the pod when an endpoint returns an HTTP 500 on the /healthz endpoint. The service, probe-pod, should never send traffic to the pod while it is failing. Please complete the following:

• The application has an endpoint, /started, that will indicate if it can accept traffic by returning an HTTP 200. If the endpoint returns an HTTP 500, the application has not yet finished initialization.

• The application has another endpoint /healthz that will indicate if the application is still working as expected by returning an HTTP 200. If the endpoint returns an HTTP 500 the application is no longer responsive.

• Configure the probe-pod pod provided to use these endpoints

• The probes should use port 8080

Context

You are tasked to create a ConfigMap and consume the ConfigMap in a pod using a volume mount.

Task

Please complete the following:

• Create a ConfigMap named another-config containing the key/value pair: key4/value3

• start a pod named nginx-configmap containing a single container using the

nginx image, and mount the key you just created into the pod under directory /also/a/path

Task:

Modify the existing Deployment named broker-deployment running in namespace quetzal so that its containers.

1) Run with user ID 30000 and

2) Privilege escalation is forbidden

The broker-deployment is manifest file can be found at:

Task:

1) First update the Deployment cka00017-deployment in the ckad00017 namespace:

*To run 2 replicas of the pod

*Add the following label on the pod:

Role userUI

2) Next, Create a NodePort Service named cherry in the ckad00017 nmespace exposing the ckad00017-deployment Deployment on TCP port 8888

Task:

Update the Deployment app-1 in the frontend namespace to use the existing ServiceAccount app.
