Kubernetes: Why and How To Get Certified

The objective of the Certified Kubernetes Administrator (CKA) program is to ensure that CKAs are competent and have the knowledge and competence to fulfill the duties required of Kubernetes administrators.

The test is online and proctored based on performance and requires solving many issues using a command line. It is an online, proctored test that requires solving problems multiple from a command CKA program is different from the Kubernetes Certified Service Provider (KCSP) program. You can be a CKA without being affiliated with the KCSP; however, for a business to be certified as a KCSP, it must have at minimum three CKAs.

What Are The Various Kubernetes Certifications?

There exist two Kubernetes certifications that are of the Kubernetes Administrator Certification (CKA) and the Certified Kubernetes Administrator (CKA), and the Certified Kubernetes Application Developer (CKAD).

Candidates receive the certification when they pass the exam. To successfully pass these tests, the candidate needs to demonstrate their knowledge of the concepts of Kubernetes as well as how the parts are interconnected. Each question is real-world, not multiple choice, and therefore you can't just make up the answer.

Certified Kubernetes Administrator (CKA)

The CKA examines your capability to configure and deploy the Kubernetes cluster, as well as your knowledge of the fundamental concepts. In order to get the CKA Certification, candidates will be provided three hours to finish the test and score 74% or better to obtain the certification.

The CKA test covers the areas of the following:

• 8% - Application lifecycle management
• 12% - Installation, configuration & validation
• 19 percent of the total
• 11 percent - Networking
• 5.5% - Scheduling
• 12% - Security
• 11% - Maintenance of the cluster
• 5% - Logging/monitoring
• 7.7% - Storage
• 10 percent Troubleshooting

Certified Kubernetes Application Developer (CKAD)

The CKAD tests your abilities to set up and deploy applications running in the Kubernetes cluster and your comprehension of the fundamental concepts. It will take you two hours to finish the CAD test. A 66% or more score signifies that you've completed the exam successfully.

To pass the CKAD test, you'll be evaluated in the areas listed below:

• 13 Percent of the Core Concepts
• 18 percent 18% - Configuration
• 10% - multi-container pods
• 18 percent 18% - Observability
• 20% - Pod design
• 13% - services & networking
• 8% - State persistence

Advantages and Benefits Of The Kubernetes Certification

Why bother to take the Kubernetes certification test? If it appears like an overwhelming amount of effort, you're probably right. However, the action is worthwhile for lots of people. Engineers with K8s certification benefit from a variety of uses:

• Get Noticed By the Crowd. A Kubernetes certification can make your resume look professional and stands out from the competitors. As businesses rely increasingly on Kubernetes, Your knowledge and experience will become an instant benefit.
• Earn a Raise. A top certification such as the CKA and the CKAD offers you an incredible chance for excellent pay. The process of passing these tests isn't an easy feat, and companies looking for engineers with k8s will spend more money because these credentials prove that you're more than only skilled, but that you know the system.
• Gain Personal Development. Passing these exams can be satisfying on a personal level. You've sacrificed your time and pleasure to study and practice to pass the exam, so passing is an accomplishment in and of the end. Then, you could shift to a different area of expertise to concentrate.
• Make Yourself the Kubernetes Professional. After passing the test, Kubernetes concepts become simple and become second nature. After the frustration that you might be experiencing as a newcomer to k8s, it is the satisfaction of knowing this is priceless and worth the effort.
• Increase and Diversify Your knowledge. The Kubernetes architecture was developed around the 12-factor apps principles. So after becoming certified in k8s, you've established a solid base in 12-factor app concepts and supports various SaaS applications. Talk about growing your skillset.

Preparing for Kubernetes Certification Exams

As with any exam, the preparation isn't easy, but it's not rocket science either. You'll require plenty of time to learn and to practice. Most successful engineers need around four months to study for 2 to 3 hours each day. Be aware it is essential to note that CKA, along with the CKAD, is not identical. The CKA includes a variety of cluster-related components, installations, and configurations. The CKAD, On the contrary, does not explore cluster configurations. However, it requires a thorough understanding of how clusters operate.

Here, you will find provided ways to prepare for the exam.

• Be familiar with Kubernetes and the components of the cluster.
• Create the group by starting from scratch. I utilized Kelsey Hightower's Kubernetes The Hard Way, and it is the most comprehensive tutorial about how the different components are connected.
• Know the concepts and learn how to use the cluster. Begin by reading this page for a wealth of information on the ideas of k8s.
• Try kubectl for a test of the results. The page includes helpful tools for advanced parsing, and Kubernetes provides relevant information.
• Watch this series of webinars on the concepts that apply to both examinations.
• The practice tests can be challenging to clear which insures better you to clear the exam easily. If you don't have hands-on experience and aren't practiced using and deploying an entire cluster. One way to get practice is to use an exam application and then deploy it to your cluster running and meet specific goals using the application. There are a lot of test apps, in case you don't have one currently.

The Process of Making a Decision

Suppose you're still deciding whether or not to take an exam like the k8s, be aware that both the CKA and the CKAD are valuable and highly sought-after qualifications. They'll improve your resume as well as increase your chances. Although the test isn't easy, there's a valid reason it's because the Kubernetes platform demands a thorough conceptual understanding and application in a production environment. Passing the test means that you'll be sure that you'll be able to apply the knowledge you've acquired in a real-world scenario.
