Certified Kubernetes Administrator (CKA)
This class prepares students for the Certified Kubernetes Administrator (CKA) exam. Kubernetes is a Cloud Orchestration Platform providing reliability, replication, and stability while maximizing resource utilization for applications and services. By the conclusion of this handsâ€on, vendor-agnostic training you will go back to work with the knowledge, skills, and abilities to design, implement, and maintain a productionâ€grade Kubernetes cluster. We prioritize covering all objectives and concepts necessary for passing the Certified Kubernetes Administrator (CKA) exam. You will be provided the components necessary to assemble your own high-availability Kubernetes environment and configure, expand, and control it to meet the demands made of cluster administrators. Your week of intensive, handsâ€on training will conclude with a mock CKA exam that simulates the real exam.
