The answer is Microsoft Defender for Cloud, as it provides the unified threat detection for Azure PaaS services like Azure SQL Database and Azure Key Vault by using built-in behavioral analytics to identify suspicious activities such as SQL injection attempts and unusual access patterns. This solution integrates alerts directly into a central SIEM system through Azure Monitor or Microsoft Sentinel, enabling comprehensive security analysis. On the SC-900 exam, this question tests your understanding of how Microsoft Defender for Cloud extends beyond basic security posture management to deliver advanced threat protection for PaaS workloads, often appearing as a scenario where you must distinguish it from Azure Security Center or Azure Sentinel alone. A common trap is confusing Defender for Cloud with Azure SQL’s built-in threat detection, but remember that Defender for Cloud unifies detection across all PaaS services, not just databases. Memory tip: think “Defender for Cloud = one shield for all PaaS threats, from SQL injection to key vault anomalies.”
SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
This SC-900 practice question tests your understanding of describe the capabilities of microsoft security solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An organization wants to protect its Azure PaaS services, such as Azure SQL Database and Azure Key Vault, by detecting and alerting on suspicious activities like SQL injection attempts or unusual access patterns. They also need to integrate these alerts into a central security information and event management (SIEM) system for further analysis. Which Microsoft security solution provides the threat detection capability described?
Why wrong: Sentinel is a cloud-native SIEM that can ingest alerts from Microsoft Defender for Cloud, but it does not directly detect threats in PaaS services by itself.
B
Microsoft Defender for Cloud
Defender for Cloud offers unified security management and advanced threat protection for Azure PaaS services, including SQL, Key Vault, and storage, with built-in threat detection alerts.
C
Microsoft Defender for Endpoint
Why wrong: Defender for Endpoint protects endpoints (devices) from threats, not PaaS services like SQL or Key Vault.
D
Microsoft Defender for Identity
Why wrong: Defender for Identity monitors on-premises Active Directory for identity-based attacks, not cloud PaaS services.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Defender for Cloud
Microsoft Defender for Cloud provides unified security management and advanced threat protection across hybrid cloud workloads, including Azure PaaS services like Azure SQL Database and Azure Key Vault. It detects suspicious activities such as SQL injection attempts and unusual access patterns using built-in behavioral analytics and integrates alerts into a central SIEM system via Azure Monitor or directly to Microsoft Sentinel.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Defender for Identity monitors on-premises Active Directory for identity-based attacks, not cloud PaaS services.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Microsoft Sentinel (a SIEM) with the threat detection capability itself, but Sentinel ingests alerts rather than generating them for PaaS services, making Defender for Cloud the correct answer for native threat detection.
Detailed technical explanation
How to think about this question
Under the hood, Microsoft Defender for Cloud uses the Log Analytics agent and Azure Monitor to collect telemetry from PaaS resources, applying machine learning models to baseline normal behavior and flag anomalies like SQL injection patterns (e.g., suspicious T-SQL commands) or unusual access to Key Vault secrets. These alerts are surfaced in the Defender for Cloud dashboard and can be streamed to a SIEM via continuous export to Event Hubs or directly integrated with Microsoft Sentinel for advanced correlation and automated response.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
