Importance of the CKA Exam
The purpose of the Certified Kubernetes Administrator (CKA) program is to provide assurance that CKAs have the skills, knowledge, and competency to perform the responsibilities of Kubernetes administrators. The CKA exam covers many crucial topics that are essential for managing and deploying Kubernetes clusters, skills that are important even if you never plan to use them in your day-to-day job.
Taking this exam is a prerequisite for companies that want to sell Kubernetes services through the Kubernetes Certified Service Provider Program (KCSP), which requires companies to hire at least three certified engineers. The exam process is a good way to learn Kubernetes even if you do not intend to use it professionally. It is a practical test in which you will be tested mainly on your ability to use Kubernetes and little on pure memorization.
