What is CNCF CKA Certification Exam

The Cloud Native Computing Foundation (CNCF) is a technology consortium designed to connect and harness the strength of existing and emerging technologies to simplify and accelerate the cloud and infrastructure modernization journey for enterprises. The Cloud Native Computing Foundation Certification Program offers a series of 3 exams to assess knowledge of cloud-native computing.

The focus of this exam is to validate the ability to operate Kubernetes cluster infrastructure and advise customers on best practices for their particular use cases. Complicated infrastructure requirements are expected to be addressed through step-by-step instructions. The exam does not measure programming or development skills. A lot of practice exercises are required to prepare for the exam. CNCF CKA exam dumps will be the best choice. Recommend using a Kubernetes cloud platform such as kubeadm to test infrastructure in a learn-by-doing approach. Confidence in working with Kubernetes will provide more confidence to the candidate while passing the exam. Assurance of obtaining the CNCF Certified Kubernetes Administrator certificate is available upon passing this exam. Products from various vendors across the industry will be tested.
