The correct hunting approach is to use Microsoft Purview DLP reports to review incidents where sensitive files were shared externally via Teams. This works because Purview DLP captures detailed policy match data specifically for sensitive content, including the context of external sharing in Teams channels and chats, whereas raw audit logs lack the aggregated, policy-focused view needed for efficient threat hunting. On the SC-200 exam, this question tests your ability to distinguish between hunting tools: Purview DLP reports are designed for data exfiltration investigations, while audit logs are too granular for initial triage, and other options like malware analysis or endpoint controls address different attack vectors. A common trap is choosing audit logs because they seem comprehensive, but remember that DLP reports pre-filter for policy violations, saving you from sifting through noise. Memory tip: DLP = Data Leakage Prevention, so think “DLP for leaks” when hunting exfiltration via Teams.
SC-200 Perform threat hunting Practice Question
This SC-200 practice question tests your understanding of perform threat hunting. 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.
You are a threat hunter investigating a potential data exfiltration via Microsoft Teams. You need to identify if any users have shared sensitive files externally. Which hunting approach should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Microsoft Purview DLP reports to review incidents where sensitive files were shared externally via Teams.
Option B is correct because Microsoft Purview Data Loss Prevention (DLP) provides detailed reports on policy matches, including external sharing. Option A is wrong because audit logs alone are too raw. Option C is wrong because it focuses on malware. Option D is wrong because it's about endpoint devices.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Analyze Microsoft Defender for Endpoint device timeline for file activity related to Teams.
Why it's wrong here
Endpoint data may not capture Teams cloud sharing activities.
✗
Run a custom detection rule in Microsoft Defender for Cloud Apps to alert on large file uploads to Teams.
Why it's wrong here
Large file uploads may not indicate external sharing.
✗
Query the Office 365 audit log for file download events from Teams.
Why it's wrong here
Audit logs may show downloads but not necessarily external sharing.
✓
Use Microsoft Purview DLP reports to review incidents where sensitive files were shared externally via Teams.
Why this is correct
DLP policies can detect and report on sensitive data shared externally, providing relevant hunting data.

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.
