Microsoft exams AI-901 and AI-103 both require a passing score of 700 or greater and price registration by the country or region of proctoring, with no US dollar figure shown, as shown in the United States on 28 October 2026.

After a first failed attempt, Microsoft requires a 24-hour wait before retaking, whereas both AWS and Google Cloud require a 14-day wait, as shown in the United States on 28 October 2026. Retake charges and scoring rules are the failure points to plan for, including paying the full registration fee for every AWS attempt and forfeiting the Google Cloud exam fee for a no-show with no refund, as shown in the United States on 28 October 2026.
