• Backtracking
  Disabled — once you answer, you cannot return to a question.
• Mark for review
  Not available on the real interface.

CKA time strategy

• CKA — Performance Tasks (15-20 · K8s v1.35)
  Target ~400 sec/question. If a question takes more than 600 seconds, mark for review and move on.
