A Study Guide for Kubernetes Certification

Kubernetes Certification

Kubernetes is a practical test. By the way, there is a qualification called CKAD for developers. Check the Candidate Handbook and Frequently Asked Questions for notes on taking the exam. There are many points to note, probably because of the online exam.

It is recommended that engineers obtain kubernetes certification. Considering that Kubernetes will be used more widely in the future, companies are looking for engineers who are not only familiar with the basic concepts of Kubernetes (how they work, what high-level components are, etc.) but also understand how to use them. 

The exam requires working with Vim or Emacs, Linux shell commands, and the Kubernetes CLI in a Linux / CLI environment. kubernetes certification training takes some time to acquire the skills and experience to become a certified Kubernetes administrator. 

Kubernetes Administrator (CKA) exam:

A certification test demonstrates your proficiency with Kubernetes and the whole cloud-native ecosystem. It is intended for developers, aspirants, administrators, architects, and managers who are fresh in cloud-native technologies and container orchestration.

It is made to ensure qualified candidates possess the expertise, understanding, and skills necessary to function as a Kubernetes administrator.

CKA tests are online supervised performance-based tests that require you to solve multiple tasks from the command line while running Kubernetes. 

The exam is very practical, consists of about 20 questions, and should be completed within 2 hours. There is also a supervisor at the test site to check the state of the test. Participants reported that most exam questions were at intermediate to challenging levels.

There are questions to create resources and identify and resolve problems (troubleshooting and fixing). In addition to having access to the memo’s location, you can copy and paste from the instructions, for example, to track pending questions.

Benefits of passing the Kubernetes exam?

Here are some of the proceeds from your efforts to prepare for the exam:

First off, CKA accreditation adds distinction to your resume. This gives you a unique opportunity to outperform your competitors by passing the CKA. The highest certifications, such as CKA, allow you to quickly establish credibility and value in the employment market, ensuring a promising career path and attractive rewards. Companies are willing to pay more for certified Kubernetes professionals because certification tests a candidate’s ability to handle all responsibilities effectively.

Exam tips

1. If you are not confident in the question during the exam, mark it as “flagged” and move on to the next question. It’s a good idea to solve relatively simple questions to get the pace, then try complex problems.

2. You don’t have to remember the YAML syntax perfectly. Use example commands or, as an alternative, copy and paste the code from Kuberenetes’ handbook.

3. Use this kubectl cheat sheet. Practice these and bookmark them for exams. One additional tab is available to browse the Kubernetes documentation for the exam. Practising this cheat sheet once or twice before the exam can save you a lot of time during the exam.

4. If you use “dry-run” to create a pod or object, keep the command in Notepad so that you can copy and paste it if you run it again in your exam. ..

5. Use Notepad to copy and edit the snippet from the Kubernetes document during the exam.

6. The CKA exam focuses on a multi-node cluster environment, so you need to know which cluster you are in before answering any questions. You will receive 0 points if you respond to the question in the incorrect cluster. Therefore, be sure to check and switch clusters before every question. All of these instructions are provided before each question. Switch to that cluster using the command given in each question.

7. When creating a resource in a cluster, do not write the YAML file from the beginning. Use “kubectl run” with the “—dry-run” flag whenever possible. When creating a YAML file with the “—dry-run” flag, creating a resource in the cluster is easier than creating it from scratch.

8. Remember that every Linux Foundation exam has one free retake. There are two chances.

 Summary 

The key to getting a kubernetes security certification is practice, practice, and practice. Even if you’ve already used Kubernetes, there’s nothing better than practising it. The more prepared you are for the exam, the better you will be able to allocate time for the exam on the day. Time management is important, so get your Kubernetes docs ready for quick use (from the console using the docs page or kubectl), get your YAML generated (don’t edit), and be prepared to withstand the pressure.
