Certified Kubernetes Administrator (CKA)

The Certified Kubernetes Administrator (CKA) certification exam is the industry-standard credential for professionals responsible for managing Kubernetes clusters in enterprise environments. Unlike traditional multiple-choice certifications, the CKA exam is completely performance-based and requires candidates to solve real administrative tasks in live Kubernetes environments.

The official Certified Kubernetes Administrator (CKA) exam consists of approximately 15 to 20 hands-on tasks, lasts 120 minutes, requires a passing score of 66%, and costs approximately $395 USD for the exam-only option. The examination is delivered online through remote proctoring and is considered an intermediate to advanced level certification for Kubernetes professionals. The exam is conducted in English and provides a globally recognized credential backed by the Cloud Native Computing Foundation and The Linux Foundation.

Organizations worldwide continue to adopt Kubernetes as the standard platform for container orchestration. As a result, demand for professionals with proven Kubernetes administration expertise continues to increase across cloud computing, DevOps, site reliability engineering, and platform engineering roles.
