12.1 Domain-Weighted Final Review Plan

Build the Final Week Around the Blueprint

The final SC-900 review should start with the official skills measured as captured in the source brief. The exam covers security, compliance, and identity concepts; Microsoft Entra capabilities; Microsoft security solutions; and Microsoft compliance solutions. The weights do not tell you the exact number of questions you will see, but they do show where Microsoft places emphasis.

Use the weights to allocate time, then use practice misses to adjust. If you are already strong in Microsoft Entra but weak in Purview, move time toward compliance. If you keep missing similar Defender names, add product-selection drills. Do not skip the smaller concept domain, because shared responsibility, defense in depth, Zero Trust, encryption, hashing, GRC, authentication, authorization, identity providers, directory services, Active Directory, and federation are the vocabulary that supports the product questions.

A Practical Three-Pass Review

• Pass 1: Coverage. Revisit every chapter summary and key takeaway so no objective area is untouched.
• Pass 2: Scenario sorting. Sort prompts into Entra, Defender, Sentinel, Purview, or concept-only buckets.
• Pass 3: Timed recall. Answer under time pressure and explain why the wrong options are wrong.
• Final check. Review names, retake rules, scoring rules, and the exam environment boundaries.

The largest domain is Microsoft security solutions, so it deserves repeated practice. That domain includes Azure DDoS Protection, Azure Firewall, Web Application Firewall, virtual network segmentation, network security groups, Azure Bastion, Azure Key Vault, Defender for Cloud, cloud security posture management, workload protection, Sentinel, SIEM, SOAR, and Microsoft Defender XDR services. The breadth is the challenge. You need recognition of what each tool is for, not administrator-level implementation steps.

Microsoft Entra is the next large review block. Focus on authentication, authorization, identity providers, hybrid identity, multifactor authentication, password protection, Conditional Access, roles, RBAC, ID Governance, access reviews, Privileged Identity Management, and ID Protection. Most misses in this domain come from confusing identity governance, privileged access, and security monitoring. Write the exact verb in the scenario before choosing.

Compliance review should be concrete. Associate Purview with classification, content explorer, activity explorer, sensitivity labels, DLP, records management, retention, insider risk, eDiscovery, and audit. Associate Service Trust Portal with Microsoft compliance and privacy resources, Microsoft Priva with privacy, and Compliance Manager with compliance score and improvement actions. End each study session by explaining one scenario from each domain without looking at notes.
