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

Microsoft Purview Compliance Manager organizes improvement actions into control action subcategories that mirror core security control types used throughout Microsoft Learn’s SCI content: preventative, detective, and corrective. In the SC-900 security fundamentals guidance, Microsoft describes these control types as follows: “Preventive controls are intended to deter or stop an attack from occurring (for example, encryption and access controls). Detective controls are used to discover and detect attacks that are in progress or have occurred (for example, logging, auditing, and monitoring). Corrective controls are used to limit the damage caused by an incident and to return systems to normal operations (for example, configuration changes, incident response, and recovery activities).”

Applying those definitions to Compliance Manager actions: Encrypt data at rest is a preventative control because it deters exposure by protecting data before an event. Perform a system access audit is a detective action because auditing and reviewing access logs are used to discover and detect misuse or anomalies. Make configuration changes in response to a security incident is a corrective action because it remediates and restores the environment after detection, aligning with Compliance Manager’s corrective action guidance. These mappings reflect how Compliance Manager measures completion of improvement actions that reduce compliance risk through the right mix of preventative, detective, and corrective controls.

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).

The Compliance score in Microsoft Purview Compliance Manager is a measurement tool that evaluates an organization’s progress toward meeting data protection and regulatory compliance requirements. It is specifically designed to help organizations reduce risks related to data governance, privacy, and compliance with various standards such as GDPR, ISO 27001, NIST 800-53, and Microsoft Data Protection Baselines.

According to Microsoft’s official documentation on Compliance Manager, the Compliance score “helps organizations track, improve, and demonstrate their compliance posture by providing a quantifiable measure of compliance with regulations and standards.” Each action within Compliance Manager contributes a certain number of points to the overall score. These points are weighted based on risk, meaning that actions with a greater impact on reducing compliance risk contribute more significantly to the total score.

The score is not an absolute measure of legal compliance but rather an indicator of progress toward implementing recommended controls and risk-reducing actions. Microsoft emphasizes that Compliance score “assists organizations in identifying areas of improvement, prioritizing compliance tasks, and maintaining an auditable record of their compliance activities.”

By contrast, Microsoft Secure Score measures security posture related to identity, device, and application protection, while Productivity Score evaluates collaboration and technology experience. Thus, the metric that specifically assesses data protection and regulatory compliance progress is the Compliance score in Microsoft Purview Compliance Manager.
