Question 1,330 of 1,639
Required Data Source for UEBA: Microsoft Entra ID Audit Logs
This SC-200 practice question tests your understanding of manage a security operations environment. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Your SOC team uses Microsoft Sentinel's UEBA to detect insider threats. You want to ensure that UEBA can correlate activities across multiple data sources. Which data source must be enabled for UEBA to function properly?

Correct answer & explanation
✓
Microsoft Entra ID audit logs
Microsoft Sentinel's UEBA relies on Microsoft Entra ID (formerly Azure AD) audit logs as the primary identity source to establish a baseline of user behavior and correlate activities across different data sources. Without these logs, UEBA cannot map activities to specific user identities, which is essential for detecting anomalous behavior patterns indicative of insider threats.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume Office 365 audit logs (Option B) are the primary identity source because they contain user actions, but Microsoft Sentinel's UEBA specifically requires Entra ID audit logs to establish the foundational identity baseline before correlating other data sources.
Detailed technical explanation
How to think about this question
UEBA in Microsoft Sentinel uses the 'User and Entity Behavior Analytics' engine, which ingests Entra ID audit logs to create a user profile graph that includes attributes like user principal name (UPN), group memberships, and sign-in patterns. This graph is then enriched with data from other sources (e.g., Office 365, Windows Events) via the 'BehaviorAnalytics' table, allowing the detection of anomalies such as impossible travel or unusual data access. Without Entra ID logs, the UEBA engine cannot link activities from disparate sources to a single user identity, rendering its correlation capabilities ineffective.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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.
