SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
Your organization needs to monitor and respond to security threats across on-premises, cloud, and hybrid environments. Which Microsoft solution provides a unified SIEM and SOAR capability?
⚠ Common exam trap
Many candidates confuse Microsoft Defender XDR (an XDR tool) with a full SIEM/SOAR solution, but Sentinel is the only Microsoft offering that provides both SIEM and SOAR capabilities natively.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Sentinel
Microsoft Sentinel is the correct answer because it is a cloud-native Security Information and Event Management (SIEM) and Security Orchestration Automation and Response (SOAR) solution. It provides unified threat monitoring, detection, and response across on-premises, cloud, and hybrid environments by ingesting data from various sources, using built-in analytics, and enabling automated playbooks.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Microsoft Defender XDR
Why it's wrong here
Microsoft Defender XDR offers extended detection and response capabilities by correlating signals across various Microsoft 365 security products like Defender for Endpoint, Identity, and Cloud Apps. While it provides robust threat protection within the Microsoft ecosystem, it is not a full Security Information and Event Management (SIEM) or Security Orchestration, Automation, and Response (SOAR) solution. It lacks the broad, vendor-agnostic log ingestion, custom analytics, and comprehensive automation features required for an organization-wide security operations center (SOC).
- ✗
Microsoft Defender for Cloud
Why it's wrong here
Microsoft Defender for Cloud primarily functions as a Cloud Security Posture Management (CSPM) and Cloud Workload Protection Platform (CWPP). It focuses on identifying misconfigurations, vulnerabilities, and threats across multi-cloud and hybrid cloud environments, enhancing the security posture of cloud resources and workloads. However, it is not designed to be a comprehensive SIEM/SOAR platform for ingesting logs from all organizational sources, including on-premises infrastructure, or for providing broad, custom security orchestration and automated response capabilities.
- ✓
Microsoft Sentinel
Why this is correct
Microsoft Sentinel is a cloud-native Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) solution. It provides comprehensive capabilities for collecting security data from diverse sources, including Microsoft services, other cloud providers, and on-premises infrastructure. Sentinel leverages AI and machine learning for threat detection, investigation, and automated response, making it the ideal platform for monitoring and responding to security threats across an entire enterprise environment.
- ✗
Microsoft Intune
Why it's wrong here
Microsoft Intune is a cloud-based service focused on Mobile Device Management (MDM) and Mobile Application Management (MAM). Its primary purpose is to manage and secure endpoints, enforce device compliance policies, and protect corporate data on mobile devices and applications. Intune is an endpoint management tool, not a security information and event management (SIEM) or security orchestration, automation, and response (SOAR) platform, and therefore does not provide the centralized log aggregation, threat analytics, or automated incident response capabilities needed for broad organizational threat monitoring.
