Certified Kubernetes Administrator (CKA) Exam Study Guide

CKA exam guide

The Certified Kubernetes Administration Exam was something that I have worked hard for.

It took me a few attempts to clear the exam, and I will share my experience regarding the same.

In this CKA Exam Study Guide, I have mentioned several tips, tricks, and strategies that you may use, as well as some of the latest Linux Foundation coupons to help you get discounts of up to 65%.

It would be best if you gave it all to gather enough knowledge about Kubernetes cluster components.

This exam combines 6 Kubernetes clusters for your practical assessments.

As an engineer, I was always interested in setting up Kubernetes clusters. This made me interested in taking the CKA Exam, one of the best DevOps certifications.

Further in this article, I will discuss all the details regarding the CKA Exam. Read along to know more!

What is the CKA Certification?

The Certified Kubernetes Administrator certification is a product of the Cloud Native Computing Foundation in collaboration with the Linux Foundation.

CNCF offers various other certifications alongside CKA, including Kubernetes and Cloud Native Associate, Certified Kubernetes Application Developer, and Certified Kubernetes Security Specialist.

The CKA program aims to ensure that certified administrators possess the requisite skills, knowledge, and competency to fulfill Kubernetes administration responsibilities. The demand for proficient DevOps Engineers with expertise in Kubernetes cluster administration is on the rise.

Earning the CKA certification opens doors to opportunities in companies and organizations leveraging Kubernetes. It signifies your capability to navigate this dynamic field and contribute effectively to the deployment and management of Kubernetes environments.

Should You Take the CKA exam?

Yes, you should take the CKA exam because this opens another door for your career in managing Kubernetes clusters.

However, there could be some conflicting opinions within the tech industry regarding the significance of certifications. Long story short, I would say that it depends on your capability and experience.

Some tech experts argue that real-world knowledge surpasses the importance of top Linux certificates, but in reality, not everyone has exposure to practical knowledge or experience.

Certification exams push you to go the extra mile when you prepare for it and often simulate real-world scenarios. It provides a valuable learning opportunity for those lacking hands-on practice.

The CKA exam is for you if you are already well-versed in a technology like Kubernetes. The certification exam can allow you to showcase your knowledge and work on complex projects.

CKA Practice Labs

The CKA practice labs help you excel in the CKA Certification exam. I used these labs to get my concepts more straightforward and practical exercises for real-world experience in Kubernetes.

They have helpful designs to help you create a practice environment using a cluster of actual machines. 

I learned how to tackle real problems on these live systems because the CKA Exam has comprehensive problems instead of multiple-choice questions.

So, the best advice to clear the CKA Exam is to practice as much as you can in the provided setups that offer you a Kubernetes cluster where you can hone your skills effectively.

My best strategy to crack CKA Practice Labs was understanding Kubernetes concepts and so much practical practice.

Certified Kubernetes Administrator Exam Modules

There are five modules in the Certified Kubernetes Administrator Exam.

  • Troubleshooting
  • Cluster Installation, Architecture, and Configuration
  • Services and Networking
  • Workloads and Scheduling
  • Storage

How do you verify your CKA Answers on the exam?

To verify your answers on the exam, I followed the steps below.

Check Pod Status

I used the following command to ensure that the pod is in the ready state.

“kubectl get pod nginx.” 

If the pod isn’t ready, look for events with the command. 

“kubectl describe pod nginx” or “kubectl logs nginx.”

Deployment Status Check

Verify the status of the deployments by using the command.

“kubectl get deployments nginx-deployment.” 

In case the deployment is not ready, then use the following command- 

“kubectl describe deployment nginx-deployment.”

Service Endpoint Verification

I used to verify the functionality of service endpoints, and launch helper pods with the image “busybox”. 

Access the helper pod with the command-

“kubectl exec –stdin –tty busybox — /bin/bash”

Retrieve the service endpoint with the command-

“kubectl get svc my-service.”
