Questions
Which one should I start with?
New to AWS or preparing for Cloud Practitioner: start with the AWS guide's free sample. Already using Kubernetes and want to get better at debugging or prepare for CKA/CKAD: start with the five free incidents.
Do I get updates?
Yes. Future editions of the AWS guide are free for buyers, and the Kubernetes lab gets maintenance updates for new Kubernetes and kind releases.
Can I get a refund?
The AWS guide has a 7-day refund policy. The Kubernetes lab has no refunds, because its five free incidents let you try it first.
