SC-100: Microsoft Cybersecurity Architect Exam Prep 2026

The SC-100 Microsoft Cybersecurity Architect certification is the architect-level capstone of the Microsoft security certification path. Unlike associate-level exams that test whether you can configure a service, the SC-100 tests whether you can design an enterprise security architecture that satisfies security, compliance, and operational requirements simultaneously. This course prepares you for exactly that.This course covers all four SC-100 exam domains across 12 modules with 198 slides of structured, exam-focused content.Domain 1, Zero Trust Strategy and Architecture, covers the three Zero Trust principles mapped to specific Microsoft controls, the six Zero Trust pillars with their primary product assignments, the Microsoft Cybersecurity Reference Architecture, the Rapid Modernization Plan phase sequence, and the Zero Trust Maturity Model.Domain 2, Security Operations and Identity, covers Microsoft Sentinel architecture including analytics rule types, SOAR automation sequencing, and SOC design patterns. It also covers the full Defender XDR product family including MDI sensor placement, MDO Plan 1 versus Plan 2 feature differences, and MDCA CASB capabilities. Identity covers hybrid authentication trade-offs, external identity scenarios, Azure RBAC versus Entra ID role separation, PIM activation types, Entra ID Governance entitlement management, Workload Identity Federation, and Continuous Access Evaluation.Domain 3, Infrastructure and Network Security, covers Defender for Servers Plan 1 versus Plan 2 feature boundaries, JIT VM Access mechanics, Defender for Containers across registry and runtime phases, Azure Key Vault Standard versus Premium versus Managed HSM, Customer-Managed Key revocation, Azure Arc for multi-cloud workload protection, Azure Firewall Standard versus Premium with IDPS and TLS inspection, WAF placement decisions between Application Gateway and Front Door, DDoS Protection tier selection, Private Endpoints versus Service Endpoints, and hub-and-spoke network topology with spoke-to-spoke routing.Domain 4, Application and Data Security, covers OAuth 2.0 flow selection, API Management JWT validation patterns, Managed Identity integration patterns, STRIDE threat modeling, Always Encrypted versus TDE versus Dynamic Data Masking trade-offs, Key Vault CMK tiers, data residency controls, and Purview classification and DLP.The course concludes with a dedicated practice scenarios and exam preparation module covering domain-by-domain scenario walkthroughs, the SC-100 trap playbook for the six most common wrong-answer patterns, a complete cheat sheet of numbers and acronyms, and exam day strategy.This course is designed for security architects and senior cloud security practitioners. It assumes you already understand what Entra ID, Azure subscriptions, and network security groups are. It builds from that foundation toward multi-layer architectural decisions at enterprise scale
