Curriculum (PDFs) - https://github.com/cncf/curriculum
Simulator - https://killer.sh
Do not pay the full price of the exam, there are always discounts at the Linux Foundation and other places.
When you pay for the exam you get to two attempts.
Tips
Delete objects using the --now flag to avoid having to unnecessarily wait for the grace period to end.
KCNA - Kubernetes and Cloud Native Associate

KCSA - Kubernetes and Cloud Native Security Associate
https://www.cncf.io/training/certification/kcsa/
A light version of the CKS. Multiple-choice questions, theoretical. Not easy, requires some knowledge.
CKA - Certified Kubernetes Administrator
https://www.cncf.io/training/certification/cka/
https://training.linuxfoundation.org/certification/certified-kubernetes-administrator-cka
Focuses on infrastructure. For sysadmins. Much harder than the KCNA.
Only covers on-prem Kubernetes clusters, no cloud provider Kubernetes environments.
Hands-on. The CKA (and the CKAD and CKS too) exam environment does not offer a UI for interacting with a Kubernetes cluster. You can only use kubectl and other command line-based tools.

Must have taken and passed the CKA exam prior to attempting the CKS exam. The hardest.
