In developmentThis course is still being brought to our full standard. The questions and notes are usable, but they have not yet been checked line by line against the vendor’s own training.

The Certified Kubernetes Administrator (CKA) exam validates your ability to install, configure, and manage production-grade Kubernetes clusters. Covering cluster architecture, workload scheduling, networking, storage, and troubleshooting, this performance-based certification proves you can administer Kubernetes environments at scale. The CKA is developed by the Cloud Native Computing Foundation (CNCF) in collaboration with the Linux Foundation.
