SC-900 Exam Dumps : Microsoft Security Compliance and Identity Fundamentals

Microsoft’s identity platform (Microsoft Entra ID, formerly Azure AD) supports built-in and custom directory roles. The official guidance states that you can “create your own custom roles to grant permissions for management of Microsoft Entra resources,” and those roles consist of specific role permissions that you select to tailor least-privilege administration. The documentation also lists Global administrator (formerly Company Administrator) as a built-in role that “has access to all administrative features” and can delegate role assignments, reset passwords for all users, and manage identity settings across the tenant. Regarding assignments, Microsoft is explicit that role assignment is many-to-many: administrators can “assign one or more roles to a user,” and the user’s effective permissions are the union of the privileges from all assigned roles. Consequently, (1) creating custom roles is supported (Yes), (2) Global administrator is indeed a defined Azure AD/Microsoft Entra role (Yes), and (3) a user being limited to only one role is incorrect (No) because multiple role assignments to the same user are permitted and commonly used to implement least privilege and separation of duties.

Box 1: Yes

Azure AD supports custom roles.

Box 2: Yes

Global Administrator has access to all administrative features in Azure Active Directory. Box 3: No

A Security Information and Event Management (SIEM) system is designed to collect and aggregate security data from multiple sources—such as servers, devices, applications, and security appliances—across an organization. It then analyzes the data for anomalies, correlations, and patterns that could indicate potential threats or breaches.

From the SCI certification learning paths, especially SC-200 (Microsoft Security Operations Analyst), Microsoft defines SIEM as follows:

“SIEM tools collect and analyze activity from multiple resources across your IT infrastructure. Microsoft Sentinel is Microsoft’s cloud-native SIEM that provides intelligent security analytics and threat intelligence to help detect and respond to security threats.”

A SIEM system:

Ingests large volumes of data (logs, events).

Uses built-in rules, AI, and analytics to identify threats.

Correlates alerts from various sources to form incidents.

Generates alerts and dashboards for security analysts.

Microsoft Sentinel, as Microsoft’s SIEM solution, embodies all of these capabilities.

Other options in the dropdown (incorrect for this context):

SOAR is focused on automating responses after SIEM alerts.

TAXII is a threat intel transport protocol, not a detection system.

ASR (Attack Surface Reduction) refers to endpoint hardening, not centralized event analysis.

✅ Therefore, the correct and Microsoft-verified term is: A security information and event management (SIEM).

Microsoft’s Windows Hello for Business replaces passwords with strong, two-factor authentication that is tied to the device and unlocked with a user gesture. The Microsoft Learn description states that Windows Hello for Business “replaces passwords with strong authentication” and that “users sign in using a gesture, such as a PIN, facial recognition, or fingerprint.” It further clarifies that the credential is protected by the device’s secure hardware and that the gesture (PIN or biometric) unlocks the private key used to authenticate. The guidance explains that “biometrics (face or fingerprint) or a PIN” are supported as the user’s sign-in method, and that the PIN “is unique to the device” and does not roam, reducing attack surface.

By contrast, email verification and security questions are not authentication gestures for Windows Hello for Business. They are not listed as supported methods for unlocking the Hello for Business key or completing interactive sign-in to Windows. Therefore, the three supported Windows Hello for Business authentication methods from the options provided are fingerprint, facial recognition, and PIN. This aligns with Microsoft’s documented model where the user enrolls a biometric (face or fingerprint) or creates a PIN, and subsequently uses that gesture to unlock the hardware-bound credential for secure sign-in and access to resources.
