Capstone

Two full timed mock exams in a live cluster, plus a broken-cluster scenario you have to diagnose and repair from scratch.

Exam format — CKA (CNCF)

Performance-based, 2 hours in a live cluster. Open book against the official documentation — which only helps if you already know where to look.
