Can I pause the timer?
No. Each section is 30 minutes and keeps running even if you close the tab — same idea as exam day.
How is scoring done?
The clusters are graded for you about every five minutes, and you can request a score anytime. Partial credit is per subtask.
What does the lab look like?
A real kubeadm cluster (one control plane, three workers, Calico) plus small extra clusters for the questions that break a control plane. You work from a base terminal and ssh into nodes, like on exam day.
