A compliance officer needs to identify users who are at risk of leaking sensitive data based on their activities such as copying files to USB drives or emailing content outside the organization. The solution must also allow reviewing the activities in a case-based workflow. Which Microsoft Purview solution should they use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Purview Insider Risk Management
Microsoft Purview Insider Risk Management is specifically designed to detect, investigate, and act on risky user activities that could lead to data leaks, such as copying files to USB drives or emailing sensitive content externally. It provides a case-based workflow for reviewing and managing these activities, aligning directly with the compliance officer's requirements.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Microsoft Purview Audit (Premium)
Why it's wrong here
Audit logs provide raw activity data but no risk analysis or built-in case management for insider risk.
✗
Microsoft Purview Communication Compliance
Why it's wrong here
Communication Compliance focuses on detecting policy violations in emails and messages, not general data exfiltration activities.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Data Loss Prevention (DLP) with Insider Risk Management, but DLP is a preventive control that blocks actions in real-time, whereas Insider Risk Management is a detective control that identifies risky users and provides a case workflow for post-event review.
Detailed technical explanation
How to think about this question
Insider Risk Management uses machine learning models to assign risk scores to user activities based on configurable indicators (e.g., USB device usage, email forwarding to external domains). It integrates with Microsoft 365 audit logs and can trigger alerts that are escalated into cases, where analysts can review evidence, add notes, and take remediation actions like escalating to eDiscovery or HR. A real-world scenario involves a user who suddenly copies thousands of files to a USB drive after receiving a termination notice; the solution would flag this as a high-risk activity and create a case for investigation.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
