What references are allowed for installing container runtimes on CKA exam?

I was looking at the official kubernetes documentation on bootstrapping with kubeadm, and it looks like the documentation links on installing a container runtime all point to pages outside of the official kubernetes documentation. My understanding was that for the CKA exam we can only use the official documentation - so what are you supposed to do if the exam asks you to bootstrap a cluster? Is a container runtimes already installed on the hosts?

Thanks!

The exam won’t ask you to bootstrap a cluster. I have never heard of it. If you did get asked this, you would only be expected to know the correct kubeadm commands. If you had to do the whole thing from scratch, it would take an hour.

Do expect to be asked to upgrade a cluster. For this you only need to know what is taught in the course.
