Can the CKA exam ask us to deploy an ha-proxy even if we can't access it's online docs?

Hi,
I'm a network engineer from Italy and I've been learning K8s for some months in after work and now I've bought CKA+LFS258 bundle. I've already completed a full CKA course on another platform and I've got straight to some points in the course, such as the highly availability section.
I've already build a 3-Controlplane nodes highly available cluster at home but I'm surely not able to configure ha-proxy without accessing online resources and so I was wondering if it is possible for them to ask us in the CKA exam to setup an highly available cluster from scratch. I think that they could ask us to add some nodes on an existing ha-proxy installation but not configuring from scratch, unless they give us access to the docs or a sample config.. what do you think about that?
I've also seen that in the labs they use kubeadm token create and then the following command:
student@cp: ̃$ openssl x509 -pubkey \ -in /etc/kubernetes/pki/ca.crt | openssl rsa \ -pubin -outform der 2>/dev/null | openssl dgst \ -sha256 -hex | sed's/ˆ.* //'
Instead of simply launching kubeadm token create --print-join-command which computes the hash instead of using 3 openssl commands which we surely won't remember for the exam and I was wondering why they show us this complex way instead of the simpler one that we can remember for the exam.
I hoped that the course could clarify some few doubts about CKA but I think it could even make them worse, since there's no way to ask the instructor about doubts.

I think there is nothing to be afraid of when it comes to this problem. The necessary data should be in the description or made available at the task. If it happened otherwise, then I think you can then appeal against the assessment of the exam and point out what is in your opinion not as it should be.
