Microsoft Security, Compliance, and Identity Fundamentals Practice Exam (Free Sample)

Between 40 and 60 items in an approximately 45–60 minute window — Microsoft no longer publishes a fixed count, so pace yourself against the clock rather than a question total. Expect multiple-choice, multiple-response, and drag-and-drop formats. The exam costs $99 USD in most regions, with local pricing and taxes elsewhere; confirm the current figure and format on Microsoft Learn before you book.

700 on a scaled 1000-point scale. That is not the same thing as answering 70% of the items correctly: Microsoft weights questions by difficulty, so the raw-to-scaled mapping varies slightly by exam form even though 700 corresponds to roughly 70% raw accuracy. The practical implication is to build margin rather than aim at the line — 80% or better on a realistic practice bank is the standard worth holding yourself to.

Microsoft security solutions is the heavyweight at 35–40% — Azure network security, Defender for Cloud, Microsoft Sentinel, and the whole Defender XDR family sit in that one domain, and it alone can carry more than a third of your score. Microsoft Entra follows at 25–30% and compliance solutions at 20–25%. The concepts domain is lightest at 10–15%, but it is also the cheapest to secure: Zero Trust, defence in depth, the shared responsibility model, and encryption versus hashing are a short study list for guaranteed marks.

It is not required. SC-900 and AZ-900 are peer fundamentals — either can be first, and neither is a prerequisite for the other. AZ-900 covers Azure infrastructure and services, while SC-900 covers security, compliance, and identity across the broader Microsoft ecosystem. Taking AZ-900 first gives useful Azure context for the networking material inside SC-900’s heaviest domain, but SC-900 stands alone as an entry point and has no experience requirement.

Under Microsoft’s current policy, fundamentals certifications including SC-900 do not expire on a fixed schedule — they stay valid unless Microsoft formally retires the exam. That is different from the role-based certifications above it, such as SC-500, which expire annually and require a free online renewal assessment. Confirm the current policy on Microsoft Learn, since renewal terms are Microsoft’s to set.

SC-900 sits at Microsoft’s fundamentals tier — its easiest classification — and tests recognition and conceptual understanding rather than hands-on configuration. Most candidates pass on the first attempt after 20 to 30 hours of focused study. The difficulty is concentrated in two places: telling similarly named products apart, such as Defender for Cloud versus Defender for Cloud Apps, and matching the right Microsoft Purview capability to the right compliance goal — sensitivity labels versus retention labels versus DLP versus records management.

The sample is a fixed 15-question set spread across the four domains at blueprint proportions, with no account needed. The full Certifym SC-900 bank contains 1000 original questions spanning ten vertical scenarios — enterprise, healthcare, financial services, manufacturing, federal, retail, SaaS, higher education, energy, and telecom — and each attempt draws 60 questions at random with a 60-minute time limit and a 70% pass mark. Every item carries a written explanation that justifies the correct answer and identifies why the near-miss distractors fall short.
