CKA scoring & marking scheme
100–1000

How CKA is conducted
Mode
Proctored — Wrexa Edge mirrors this with a webcam-based proctoring flow (face detection, room scan, fullscreen lock, tab-switch detection).
Test format
Linear / fixed-form — every candidate sees the same number of questions per section.
Backtracking
Disabled — once you answer, you cannot return to a question.
Mark for review
Not available on the real interface.
CKA time strategy
With 18 questions in 120 minutes, you have about 400 seconds per question on average. Successful candidates aim for the following pacing on each section:
CKA — Performance Tasks (15-20 · K8s v1.35)
