kubeadm init prints several preflight WARNING lines and then continues. What does this tell you?

  1. Warnings do not stop the run; only preflight errors do
  2. Warnings were downgraded because --ignore-preflight-errors was set
  3. The control plane was installed but left unstarted
  4. Warnings are printed after installation, so the checks passed
Show the answer

Answer: A. Warnings do not stop the run; only preflight errors do

kubeadm init runs its prechecks first, printing warnings and exiting only on errors, so a run that continues past warnings has passed the blocking checks.
