1.6 Skills Measured and Study Map
Key Takeaways
- The SC-900 skills measured are organized into four weighted areas as of November 7, 2025.
- Microsoft security solutions have the largest weight at 35-40 percent.
- Microsoft Entra is weighted at 25-30 percent and is central to identity scenarios.
- The first domain is smaller at 10-15 percent but supplies vocabulary used throughout the guide.
Use the official weights as the study map
The Microsoft SC-900 study guide lists the skills measured as of November 7, 2025. The four areas are not evenly weighted. Describe the concepts of security, compliance, and identity is 10-15 percent. Describe the capabilities of Microsoft Entra is 25-30 percent. Describe the capabilities of Microsoft security solutions is 35-40 percent. Describe the capabilities of Microsoft compliance solutions is 20-25 percent.
The weights should shape time allocation without causing you to skip foundational material. Domain 1 is the smallest range, but it defines terms that appear everywhere else. If authentication, authorization, Zero Trust, shared responsibility, and GRC are fuzzy, later product questions become harder.
| Skills measured area | Weight | Study role |
|---|---|---|
| Security, compliance, and identity concepts | 10-15% | Vocabulary and scenario foundation. |
| Microsoft Entra capabilities | 25-30% | Identity, access, governance, and protection. |
| Microsoft security solutions | 35-40% | Azure security, Defender for Cloud, Sentinel, and Defender XDR. |
| Microsoft compliance solutions | 20-25% | Service Trust Portal, Priva, Purview, and compliance workflows. |
This study guide follows that progression. Chapter 2 covers shared responsibility, defense in depth, Zero Trust, encryption, hashing, GRC, and identity fundamentals. Chapters 3 and 4 build the Microsoft Entra domain. Chapters 5 through 8 cover Azure infrastructure security, Defender for Cloud, Microsoft Sentinel, and Microsoft Defender XDR. Chapters 9 and 10 cover Service Trust Portal, Priva, Microsoft Purview, and compliance capabilities. Chapters 11 and 12 focus on product selection, final review, timed practice, and next steps.
How to use the map
-
Start with Domain 1 even though it has the smallest weight.
-
Spend proportionally more time on Microsoft security solutions because it is the largest weighted area.
-
Treat Microsoft Entra and Microsoft Purview as separate domains with different exam cues.
-
Use final review to compare similar product names and scenario verbs.
The official study guide also notes that related topics may be covered in the exam and that most questions cover generally available features, while preview features may appear if commonly used. For SC-900 preparation, that means you should not memorize only a narrow list of product slogans. Learn the purpose and boundary of each capability.
Because the weights are ranges, use them as priorities rather than exact point forecasts. The exam can vary, so your study map should build durable recognition across all four areas before narrowing final review.
A domain-weighted plan might use the first pass for concept vocabulary, the second pass for product families, and the third pass for timed scenario recognition. In each pass, ask what problem the question is trying to solve. Is it verifying an identity, reducing network exposure, detecting threats, responding with SIEM and SOAR, protecting data, or demonstrating compliance? That question usually points to the right part of the SC-900 map.
