Linux Foundation CKAD Certified Kubernetes Application Developer Exam Practice Test

Refer to Exhibit.

Task:

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

Refer to Exhibit.

Context

A project that you are working on has a requirement for persistent data to be available.

Task

To facilitate this, perform the following tasks:

* Create a file on node sk8s-node-0 at /opt/KDSP00101/data/index.html with the content Acct=Finance

* Create a PersistentVolume named task-pv-volume using hostPath and allocate 1Gi to it, specifying that the volume is at /opt/KDSP00101/data on the cluster's node. The configuration should specify the access mode of ReadWriteOnce . It should define the StorageClass name exam for the PersistentVolume , which will be used to bind PersistentVolumeClaim requests to this PersistenetVolume.

* Create a PefsissentVolumeClaim named task-pv-claim that requests a volume of at least 100Mi and specifies an access mode of ReadWriteOnce

* Create a pod that uses the PersistentVolmeClaim as a volume with a label app: my-storage-app mounting the resulting volume to a mountPath /usr/share/nginx/html inside the pod

Refer to Exhibit.

Task

A deployment is falling on the cluster due to an incorrect image being specified. Locate the deployment, and fix the problem.

Refer to Exhibit.

Task

A Deployment named backend-deployment in namespace staging runs a web application on port 8081.

Refer to Exhibit.

Task:

1) Create a secret named app-secret in the default namespace containing the following single key-value pair:

* 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

Refer to Exhibit.

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
