SC-100 Tests Which Framework or Product Boundary Solves the Requirement — Not Portal Clicks
SC-100 is the expert-level architect exam built on long case studies. Stop asking how to configure a feature and start asking which framework, product and priority satisfies every stated constraint at once.
Check Your Readiness →Most candidates understand Microsoft Cybersecurity Architect (SC-100) concepts — and still fail. This exam tests how you apply knowledge under pressure.
Expect case studies describing tenants, hybrid AD, AWS or GCP accounts, OT plants and regulators. Several options are real Microsoft features; the right one meets every requirement with the least administrative effort. 700/1000 to pass; Microsoft does not publish the question count.
Switch the vault to geo-redundant storage
Replication copies deletions too. Enable immutable vault with locked immutability, soft delete and multi-user authorization so one compromised admin cannot remove protection, and move privileged roles to PIM with just-in-time activation and approval.
Deploy Defender for Endpoint to every controller
Recommend Defender for IoT, which inventories OT devices, surfaces vulnerabilities and detects threats passively from mirrored network traffic. Endpoint agents and active scans can disrupt industrial controllers and are usually unsupported on them.
Upgrade the VPN gateways and add MFA at connection
Use Microsoft Entra Private Access in Global Secure Access, which grants per-app access evaluated by Conditional Access without inbound firewall openings. A VPN still exposes whole network segments once a user connects.
Disable Microsoft 365 Copilot until further notice
Copilot only returns what users can already access. Fix the cause with DSPM for AI to find oversharing, permission cleanup, sensitivity labels with encryption, and DLP; the files stay reachable through search even with Copilot off.
Track them with Purview Compliance Manager improvement actions
Compliance Manager measures posture; it does not enforce Azure settings. Assign an Azure Policy with the deny effect at a management group so it inherits down every landing zone subscription. Audit only reports and fails a prevent requirement.
Microsoft's ransomware guidance ranks recoverable backups and protected admin accounts first. Azure Backup needs immutable vaults, soft delete and multi-user authorization; geo-redundant storage alone replicates deletions. Pick endpoint tuning only after recovery cannot be destroyed.
MCRA shows how capabilities connect; MCSB is the control baseline Defender for Cloud assesses by default; CAF and landing zones govern the whole estate; WAF reviews one workload. Words like assess, all subscriptions or single application point to different answers.
Defender XDR natively correlates Microsoft 365 and endpoint signals and performs automatic attack disruption. Add Sentinel for third-party firewalls, AWS CloudTrail, custom analytics, playbooks and low-cost long retention in the Sentinel data lake, all in the unified Defender portal.
Attack path analysis, cloud security explorer and governance rules require the paid Defender CSPM plan. Foundational CSPM gives Secure Score and MCSB recommendations only. A requirement to prioritise risk by reachable critical assets also points to Microsoft Security Exposure Management.
Moving a connection string into Key Vault is weaker than removing it. Managed identities authenticate Azure resources with no stored credential, and workload identity federation lets GitHub Actions or Kubernetes exchange tokens with Entra ID. AI agents should get Entra Agent ID identities, not app secrets.
