The correct approach is to query the CloudAppEvents table, summarize by AccountDisplayName and bin(TimeGenerated, 1h), then use dcount(CountryCode) > 1. This works because CloudAppEvents captures raw user activity across all integrated cloud apps, including the CountryCode field derived from IP geolocation, allowing you to group events into one-hour time bins and flag any user who appears in multiple distinct countries within that window—a classic sign of impossible travel. On the SC-200 exam, this question tests your ability to distinguish between tables: SecurityAlert contains only generated alerts, OfficeActivity is limited to Exchange and SharePoint, and CommonSecurityLog is for on-premises firewall logs, not cloud app data. A common trap is reaching for SecurityAlert because it sounds relevant, but raw detection requires the source table. Memory tip: think “CloudAppEvents = cloud raw data with country codes; bin by hour, count distinct countries, flag the jumpers.”
SC-200 Perform threat hunting Practice Question
This SC-200 practice question tests your understanding of perform threat hunting. 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.
You are a security analyst at Fabrikam. The company uses Microsoft Defender for Cloud Apps and Microsoft Sentinel. During a threat hunt, you need to identify users who are accessing cloud applications from multiple geographic locations in a short time, which could indicate credential theft or token replay. You want to create a hunting query in Microsoft Sentinel using the CloudAppEvents table. Which approach should you take?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Query CloudAppEvents, summarize by AccountDisplayName and bin(TimeGenerated, 1h), then use dcount(CountryCode) > 1
Option A is correct because CloudAppEvents contains location data (CountryCode or IPLocation). By summarizing per user and bin by time, you can group activities by user and time window, then filter for those with multiple distinct countries. Option B is incorrect because SecurityAlert contains alerts, not raw events. Option C is incorrect because OfficeActivity only covers Office 365, not all cloud apps. Option D is incorrect because CommonSecurityLog is for on-premises network devices, not cloud apps.
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.
✗
Query CommonSecurityLog for VPN connections
Why it's wrong here
CommonSecurityLog does not contain cloud app activities.
✗
Query OfficeActivity for sign-in logs
Why it's wrong here
OfficeActivity is limited to Office 365, not all cloud apps.
✗
Query SecurityAlert for location-related alerts
Why it's wrong here
Alerts are generated by rules, not raw location data.
✓
Query CloudAppEvents, summarize by AccountDisplayName and bin(TimeGenerated, 1h), then use dcount(CountryCode) > 1
Why this is correct
This directly identifies users with activities in multiple countries within an hour.

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.
