Lab 15.1 - Question on the lab output

Hello,

I am using k8s 1.27 and followed the instruction for installing my node, however I don't have the same output as in the lab when running the command below ( I should have a bootstrap-token if I follow the lab)

harimino@cp-node:~$ kubectl -n kube-system get secrets
No resources found in kube-system namespace.

What is the reason for this ?

Second question what is the difference between REDACTED and the ouput below

apiVersion: v1
clusters:

• cluster:
  ** certificate-authority-data: DATA+OMITTED**
  server: https://k8scp:6443
  name: kubernetes
  contexts:
