Course structure

The 3 practice tests contain 65, 65 and 20 questions respectively, for 150 questions in total. The original 2 tests allow up to 240 minutes each; the additional 20-question test allows 30 minutes. Questions are randomized, and 70% is a practice threshold, not the official exam passing score. Domain labels help you identify weak areas after each attempt.

Recommended study method

Take a test under timed conditions before reading the explanations. Review every incorrect answer and every question you answered without confidence. Compare all option explanations, verify unfamiliar details in the current official exam guide and vendor documentation, and retake weak areas after a few days.

Who this course is for

This course is intended for candidates preparing for Microsoft Certified: Security, Compliance, and Identity Fundamentals, learners who have reviewed the official exam guide or another training resource, and professionals who want scenario-based practice with explanations for both correct and incorrect choices.

Quality and currency

The source questions were checked for structure, duplicates, answer consistency, technical accuracy, and alignment with the current SC-900 domains. Cloud services, products, and certification objectives change, so review the latest official exam guide before your exam.
