Microsoft Security, Compliance, and Identity Fundamentals (SC-900) Practice Exams

Microsoft Security, Compliance, and Identity Fundamentals (SC-900) is a beginner-level certification from Microsoft for anyone who wants to demonstrate foundational knowledge of security, compliance, and identity (SCI) concepts and related Microsoft cloud-based solutions. It validates a clear understanding of the Microsoft security portfolio across Microsoft Entra, Microsoft Defender, Microsoft Sentinel, Microsoft Purview, and Microsoft Priva, plus the core concepts of Zero Trust, defense in depth, the shared responsibility model, and regulatory compliance.

SC-900 targets business stakeholders, students, career switchers, and IT professionals who need a structured introduction to SCI on the Microsoft cloud. People in product, project management, sales, support, audit, legal, and compliance roles often pursue it to understand the language and capabilities of Microsoft's security stack, while administrators and analysts use it as a stepping stone toward role-based certifications such as SC-200, SC-300, SC-400, and AZ-500. No prior technical experience is required.

The exam itself is short and conceptual. Candidates typically face around 40 to 60 multiple-choice and multi-response questions in a 45-minute window, with a passing score of 700 out of 1000. Microsoft frames most questions as scenarios that ask which Microsoft service, capability, or principle is most appropriate, rather than asking for deep configuration details. Topics span security and identity concepts, Microsoft Entra (Entra ID, Conditional Access, PIM, ID Protection, identity governance), Microsoft security solutions (Defender for Cloud, Defender XDR, Sentinel, Azure network security), and Microsoft compliance solutions (Microsoft Purview, Priva, eDiscovery, audit, insider risk, DLP, sensitivity and retention labels).

Mock exam practice is one of the most efficient ways to prepare for SC-900. Question wording often hinges on subtle distinctions, such as Defender for Cloud versus Defender XDR versus Microsoft Sentinel, or sensitivity labels versus retention labels versus DLP. Working through realistic scenario-style questions trains you to map a business problem to the correct service, identify common distractors, and reinforce vocabulary like Zero Trust pillars, the shared responsibility model, and the difference between authentication and authorization. It also helps surface gaps in newer areas like Microsoft Entra Verified ID, Permissions Management, and Defender for Cloud's regulatory compliance dashboard.

These SC-900 practice exams give you 25 sets of 20 questions, distributed across the four official exam domains: security, compliance, and identity concepts; the capabilities of Microsoft Entra; the capabilities of Microsoft security solutions; and the capabilities of Microsoft compliance solutions. Each question comes with a detailed explanation that tells you why the correct answer is right and why the other options are wrong, so you build understanding as you go. The first set is completely free, with options to unlock additional sets to keep practising for as long as you need.
