Kubernetes has become a widely popular tool for container orchestration in software development, with numerous IT professionals utilizing it. If you are a technology enthusiast, obtaining a Kubernetes certification could be a great way to demonstrate your competence in the platform.
Knowing the necessary steps for becoming a certified Kubernetes administrator (CKA) can expedite your certification process.
This write-up delves into the reasons why acquiring CKA expertise could be beneficial, outlines the mandatory procedures for certification, offers practical advice for acing the exam, and addresses frequently asked questions on the subject.
Why learn how to become a CKA?
Becoming a CKA is an effective means of demonstrating your expertise and experience with Kubernetes, as well as your technological prowess.
The CKA test is comprehensive, assessing your capacity to develop, oversee, and troubleshoot Kubernetes clusters and cloud-based applications.
Attaining this certification serves as a testament to your comprehensive grasp of the Kubernetes framework.
Numerous professionals seek CKA certification to enhance their credentials and improve employment prospects.
Obtaining the certification can validate your credibility and reassure potential employers that you possess the necessary competencies, knowledge, and skill set to perform the responsibilities of a Kubernetes administrator.
How to Become a CKA
Are you ready to begin exploring how to become a CKA? If so, let’s dive in with some simple steps that can help you acquire the necessary knowledge and skills to pass the exam and obtain the certification.
To become a certified Kubernetes administrator professional, you can adhere to the following guidelines:
1. Acquire Additional Knowledge about Kubernetes.
To ensure success in the CKA exam, it is essential to have a solid understanding of Kubernetes.
Although anyone can take the exam regardless of their current skills and credentials, it’s advisable to acquire more knowledge about the platform.
You can find various resources online to enhance your technical skills and better prepare for the exam. Here are a few topics to consider studying:
- YAML: Familiarizing yourself with YAML can be useful since professionals sometimes use it to create Kubernetes resources.
- Linux: During the CKA exam, you may encounter practical questions in a Linux command line interface. Learning how to navigate and perform basic operations in Linux can give you an added advantage.
- Container runtime: As container runtimes are essential components of Kubernetes, learning at least one tool to execute and deploy containers efficiently can be very helpful.

Based on the exam curriculum, it’s important to note that the CKA exam covers various topics related to Kubernetes. The exam requires you to demonstrate your understanding of Kubernetes setup and configuration.
Here’s an approximate breakdown of the topics to expect and their respective weightage:
- Cluster architecture, installation, and configuration: 25% This topic covers Kubernetes cluster setup, configuration, and maintenance. It also includes understanding Kubernetes architecture, components, and their interactions.
- Workloads and schedule: 15% This topic covers creating, configuring, and managing Kubernetes workloads, including deploying, scaling, and updating containers.
- Services and networking: 20% This topic covers Kubernetes service discovery and networking, including creating, configuring, and managing Kubernetes services and networking policies.
- Storage: 10% This topic covers Kubernetes storage, including the ability to configure and manage persistent storage for Kubernetes applications.
- Troubleshooting: 30% This topic covers Kubernetes troubleshooting, including identifying and resolving issues related to the Kubernetes cluster, workloads, services, and networking.
3. Study Highlighted Curriculum Topics
To prepare for the CKA exam, it’s important to review the exam curriculum and identify the topics and courses listed.
This can serve as a useful guide to help you organize your study materials and ensure that you’re meeting the exam requirements.
For example, you may be required to demonstrate your ability to create robust deployments in the workloads and scheduling section or show your knowledge of volume and volume chains in the storage section.
The most challenging aspect of the exam may be troubleshooting a Kubernetes cluster, so it’s important to practice this skill regularly.
It’s also worth noting that the certification board may change or upgrade the software version used for the exam, so it’s a good idea to stay up-to-date with the current Kubernetes version required for the exam.
4. Attempt Mock Tests
Utilizing learning materials that include practice tests for each topic or lesson can enhance your learning potential.
By incorporating courses with practice tests, you can acquire practical experience in all the subjects covered, which can aid in effective learning and prepare you for taking Kubernetes-related exams like the CKA.
Additionally, practising with tests can help you save money that would have otherwise been spent on running a personal Kubernetes cluster.
5. Complete Various Exercises
To increase your chances of success in the CKA exam, focus on solving numerous exercises.
The exam is designed to test your practical skills, so practising with a variety of exercises can help you become comfortable with the exam format.
Remember, you have two chances to take the exam per registration. During your first attempt, take your time to carefully solve each exercise, using the official Kubernetes documentation as a resource to find the correct solutions.
6. Get Your Test Environment Ready
Ensure that you have access to an appropriate testing environment prior to the exam.
Using a cloud-based environment can provide an optimal testing environment, allowing for the easy creation of load balances and ingress controllers as opposed to a local environment.
7. Register for the exam
To register for the exam, create a user account on the official Linux Foundations website, and pay the registration fee through the user portal.
Choose an exam date and time that aligns with your preparation progress. Adequate preparation can help you successfully pass the exam and achieve your objectives.
