Start guided practiceThe benchmark Kubernetes administrator exam, taken entirely in a live cluster: architecture and installation, workloads and scheduling, networking, storage, and troubleshooting under time pressure.
CNCF does not publish numeric exam codes — CKA is the common abbreviation.
Certified Kubernetes Administrator is CNCF's professional-level containers & kubernetes certification, referred to across the industry by the shorthand CKA. The exam runs for 2 hours, with a pass mark of 66%. It costs US$445 at the standard rate.
CNCF publishes the syllabus as 5 weighted domains. Troubleshooting carries the most weight at 30%, and the three largest domains together account for roughly 75% of the scored content — worth knowing before you decide where study time goes.
Two hours is not long for the CKA task list. The candidates who finish comfortably are the ones who use imperative kubectl commands with dry-run output rather than writing manifests from scratch, and who set up aliases and context switching in the first minute.
Confirm these details on the official CNCF page before booking — vendors adjust format and pricing without notice.
