Any certificate you receive is worthwhile because it gives credibility to your skills. Certifications demonstrate that you have gotten hands-on expertise with a specific technology and have worked on a variety of industry-standard projects, demonstrating to recruiting professionals that you can hit the ground running due to your domain knowledge.
The industry, particularly with Kubernetes, is seeking individuals who have worked on the domain, and that level of competence can only be gained by hands-on experience with industry-standard projects, which any decent online certification-based training will deliver.

3 Golden Rules of how to prepare for the CKA exam
How to pass Certified Kubernetes Administrator exam? Apart from working experience with Kubernetes supported with the dedicated training course, the following are the key rules to be successful:
1. Read official CKA exam resources:
- Candidate Handbook
- Quick Guide to Register-Schedule-Take Exam
- Important Instructions: CKA and CKAD

- Kubectl cheat sheet
- RBAC authorisation
- Kubernetes objects
- Kubectl to Create a Deployment
- Scale Your App
- Kubernetes Networking
- More about Network Policies
- Ingress Controllers
- Kubernetes Logging
- Kubernetes Storage

3. Very important! Practice, practice, practice.
Most significantly, you will be able to use the documentation for the exam. As a result, studying the official documents is essential for the test. Don’t forget to practice each topic as the exam is performance-based that needs you to solve numerous issues. The following materials are great for practical exercises:
Recommendations during the test
The exam is not an easy one, taking 3 hours of serious work to complete 24 questions. Have a strategy for the exam. The following are some tips for you to consider:
- Don’t start with difficult questions. Complete ten simple questions during first hour, eight medium questions in the second hour, and the last six difficult questions in the last hour. Don’t forget to save the outputs after completion of each question.
- Try not to read all questions upfront. If you feel you need more time to resolve the problem or not sure how to answer, put the question to appropriate section of medium or difficult and come back to this question later.
- To save time, create appropriate resources using kubectl and not from manifest files.
- Don’t be nervous and remember – you have one free re-take if something went wrong. Not passing the exam is not the end of the world – take this as lessons learnt and use as an opportunity to improve.
Kubernetes is the most exciting technology of a decade and is worth knowing since it is here to stay for the foreseeable future. Even if you aren’t qualified with official certification, demonstrating that you understand it well can greatly benefit your career.
However additional benefit of holding an official CKA certificate is invaluable as it enables qualified administrators to effectively demonstrate their authority and value in the professional world, while also helping companies to employ high-quality employees.
Finally, keep in mind that showing the certificate itself will probably not land you a job. Most likely you will be shortlisted during the recruitment process and the company will verify your skills on interview. So that the main goal is not certification as a piece of paper, but rather acquiring the skills and expertise required by the company confirmed by a certificate.
