I'm pretty sure the answer is C, but I'll double-check the Kubeadm documentation just to be sure. I don't want to risk getting this wrong.

I remember learning about the Kubeadm authentication methods in class, but I'm drawing a blank right now. I'll have to use the process of elimination to try and figure this out.

Okay, I've got this. Kubeadm defaults to X509 client certs, Bootstrap tokens, and Service Account Tokens for authentication. I'm confident that's the right answer.
