Question 196 of 1,639
Investigate User Activities with OfficeActivity in Microsoft Sentinel
This SC-200 practice question tests your understanding of respond to security incidents. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
A SOC analyst is investigating an incident where a user's credentials were compromised. The analyst uses Microsoft Sentinel to find all activities performed by the user in the last 24 hours. Which data source should the analyst query FIRST to get the most comprehensive view of the user's actions across Microsoft 365?

Correct answer & explanation
✓
OfficeActivity
OfficeActivity (Option B) is the correct first query because it captures user actions across Exchange Online, SharePoint Online, OneDrive for Business, Teams, and other Microsoft 365 workloads via the unified audit log. This provides the most comprehensive view of a user's activities—including email sends, file accesses, and Teams messages—within the last 24 hours, which is essential for investigating compromised credentials.
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 choose SigninLogs (Option D) thinking it covers all user actions, but it only shows authentication events, not the actual activities performed after sign-in, which is a common misconception tested in SC-200.
Trap categories for this question
Command / output trap
AzureActivity shows Azure resource activities, not Microsoft 365.
Detailed technical explanation
How to think about this question
The OfficeActivity table in Microsoft Sentinel ingests data from the Microsoft 365 unified audit log, which uses the Management Activity API to record over 1,000 event types across Exchange, SharePoint, Teams, and more. A key subtlety is that the unified audit log has a default retention of 90 days (with an E5 license) and can be searched via the Search-UnifiedAuditLog cmdlet in Exchange Online PowerShell, making it the authoritative source for user activity reconstruction.
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.
