The answer is to query CloudAppEvents in Advanced hunting using KQL, filtering by the SharePoint site URL and the IP category ‘AnonymousProxy’. This is correct because CloudAppEvents captures granular cloud app activity, including SharePoint site-level access, and its IP category field directly classifies addresses like AnonymousProxy, VPN, or Corporate, making it the only data source that can reliably identify all users accessing the same site from anonymous IPs. On the SC-200 exam, this question tests your ability to choose the right hunting table for cloud app scenarios—a common trap is selecting Azure AD sign-in logs, which lack SharePoint site-level detail, or Microsoft Defender for Endpoint, which focuses on device-level events. Remember the memory tip: “CloudAppEvents for cloud apps, Azure AD for auth only”—when you need site-level access from anonymous IPs, always start with the CloudAppEvents table and the IP category filter.
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.
Your organization uses Microsoft Defender for Cloud Apps and Microsoft Sentinel. During a threat hunt, you find that a user accessed a sensitive SharePoint site from an anonymous IP address. Which hunting method would best identify all users who accessed the same site from similar anonymous IPs?

Correct answer & explanation
✓
Query CloudAppEvents in Advanced hunting for the SharePoint site URL and filter by IP category 'AnonymousProxy'
Using KQL to query CloudAppEvents for the specific SharePoint site and filtering by IP address categories (e.g., AnonymousProxy) is the most direct method. Option A (Azure AD sign-in logs) may not include SharePoint site-level access. Option B (Microsoft Defender for Endpoint) is for endpoint activities. Option D (Microsoft Purview) focuses on data classification and governance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Query CloudAppEvents in Advanced hunting for the SharePoint site URL and filter by IP category 'AnonymousProxy'
Why this is correct
CloudAppEvents captures cloud app activities, including SharePoint access, and IP categories help identify anonymous proxies.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Query DeviceEvents for network connections from the anonymous IP
Why it's wrong here
DeviceEvents track endpoint processes, not cloud app access.
✗
Use Microsoft Purview to scan for sensitive data accessed from anonymous IPs
Why it's wrong here
Microsoft Purview is for data governance, not real-time activity hunting.
✗
Search Azure AD sign-in logs for the same IP
Why it's wrong here
Azure AD sign-in logs show authentication, not specific SharePoint site access.

TExam Day Tips
→Underline the problem statement mentally.
→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.
