100% Reliable Microsoft CKA Exam Dumps Test Pdf Exam Material

The CKA certification exam is a hands-on, performance-based assessment that tests an individual’s ability to perform real-world tasks on a Kubernetes cluster. CKA exam consists of a set of performance-based tasks that are designed to assess an individual’s knowledge and skills in Kubernetes administration. CKA exam is conducted in a live environment, and candidates are required to demonstrate their ability to perform tasks such as configuring nodes, managing pods, and troubleshooting network issues. CKA exam is designed to test an individual’s ability to work efficiently and effectively with Kubernetes clusters.

NO.19 A Kubernetes worker node, named wk8s-node-0 is in state NotReady. Investigate why this is the case, and perform any appropriate steps to bring the node to a Ready state, ensuring that any changes are made permanent.
You can ssh to the failed node using:
[student@node-1] $ | ssh Wk8s-node-0
You can assume elevated privileges on the node with the following command:
[student@w8ks-node-0] $ | sudo -i

NO.20 Print pod name and start time to “/opt/pod-status” file

NO.21 Create a Kubernetes secret as follows:
* Name: super-secret
* password: bob
Create a pod named pod-secrets-via-file, using the redis Image, which mounts a secret named super-secret at
/secrets.

NO.22 Deployment
a. Create a deployment of webapp with image nginx:1.17.1 with
container port 80 and verify the image version

// Create initial YAML file with -dry-run option
kubectl create deploy webapp –image=nginx:1.17.1 –dryrun=client -o yaml > webapp.yaml vim webapp.yaml apiVersion: apps/v1 kind: Deployment metadata:

NO.23 Schedule a pod as follows:
Name: nginx-kusc00101
Image: nginx
Node selector: disk=ssd

NO.24 Score: 5%

Task
Monitor the logs of pod bar and:
* Extract log lines corresponding to error
* Write them to /opt/KUTR00101/bar

NO.25 Create a Cronjob with busybox image that prints date and hello from kubernetes cluster message for every minute

CronJob Syntax:
* –> Minute
* –> Hours
* –> Day of The Month
* –> Month
* –> Day of the Week
*/1 * * * * –> Execute a command every one minutes.
vim date-job.yaml
apiVersion: batch/v1beta1
kind: CronJob

schedule: “*/1 * * * *”
jobTemplate:

kubectl apply -f date-job.yaml
//Verify
kubectl get cj date-job -o yaml

NO.26 You have a Kubernetes cluster with multiple namespaces. You need to set up RBAC to allow a specific user, “developer”, to only deploy and manage pods within the “dev” namespace, but restrict access to other resources.

NO.27 Create a busybox pod and add “sleep 3600” command

NO.28 Monitor the logs of pod foo and:
Extract log lines corresponding
unable-to-access-website
Write them to/opt/KULM00201/foo

NO.29 Create the nginx pod with version 1.17.4 and expose it on port 80

NO.30 Score: 7%

Task
Create a new NetworkPolicy named allow-port-from-namespace in the existing namespace echo. Ensure that the new NetworkPolicy allows Pods in namespace my-app to connect to port 9000 of Pods in namespace echo.
Further ensure that the new NetworkPolicy:
* does not allow access to Pods, which don’t listen on port 9000
* does not allow access from Pods, which are not in namespace my-app

NO.31 Get the deployment rollout status

NO.32 You have a Kubernetes cluster with two namespaces: ‘dev’ and ‘prod’. You want to configure RBAC to allow developers in the ‘dev’ namespace to create deployments and pods, but only allow operations personnel in the ‘prod’ namespace to delete deployments and pods.

NO.33 List all the pods showing name and namespace with a json path expression

NO.34 Get IP address of the pod – “nginx-dev”

NO.35 Create a file called “config.txt” with two values key1=value1
and key2=value2. Then create a configmap named “keyvalcfgmap” andread data from the file “config.txt” and verify that configmap is created correctly

cat >> config.txt << EOF
key1=value1
key2=value2
EOF
kubectl create cm keyvalcfgmap –from-file=config.txt
//Verify
kubectl get cm keyvalcfgmap -o yaml

cat >> config.txt << EOF
key1=value1
key2=value2
EOF
cat config.txt
// Create configmap from “config.txt” file
kubectl create cm keyvalcfgmap –from-file=config.txt
//Verify
kubectl get cm keyvalcfgmap -o yaml
