Scoring method: Microsoft reports a scaled score from 1 to 1,000 and 700 or greater is required to pass; the scale is not a percentage and items can carry different weights. Some items may be unscored, and the result with a skill-area performance breakdown is shown immediately after the exam for most exams.. The exam may include unscored pilot questions - treat every question seriously.

⏭

Know both Entra Connect Sync and Cloud Sync, including IdFix preparation and troubleshooting, for the 25-30% identity domain.

📊

Remember that the Expert certification also needs a qualifying associate certification (for example MD-102, MS-700, SC-300 or SC-401).
