- A
Use DeviceNetworkEvents to find connections to file sharing service IPs, then correlate with AADSignInEventsBeta by user.
Why wrong: Network events alone lack sign-in context and may miss personal devices.
- B
Filter CloudAppEvents for app categories 'file sharing' and where IP is in corporate range, then join with DeviceInfo for device ownership.
Why wrong: DeviceInfo may not include personal devices.
- C
Join AADSignInEventsBeta with CloudAppEvents on AccountUpn, filter for app categories containing 'file sharing', and where IPAddress is in the corporate range.
Directly identifies the exact sign-in event to file sharing apps from corporate IPs.
- D
Use DeviceNetworkEvents to find high-volume outbound traffic to cloud storage provider IP ranges, then manually investigate users.
Why wrong: Inefficient and lacks precision.
Quick Answer
The correct approach is to join AADSignInEventsBeta with CloudAppEvents on AccountUpn, filter for app categories containing 'file sharing', and restrict to corporate IP ranges. This works because it directly correlates the user’s Entra ID sign-in with the specific cloud app activity, isolating personal device access to blocked file sharing services from the corporate network. On the SC-200 exam, this tests your ability to combine identity and cloud app logs for threat hunting, avoiding traps like relying solely on DeviceNetworkEvents (which miss app context) or device info (which excludes personal devices). A common mistake is filtering by app name instead of category, which can miss services like Google Drive. Remember the mnemonic: “Join UPN, filter category, check IP” — this sequence ensures you detect data exfiltration via personal devices without false positives from known good service accounts.
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 security analyst at Contoso. You manage a Microsoft Sentinel workspace with Microsoft Defender for Cloud Apps, Microsoft Defender for Endpoint, and Microsoft Entra ID (formerly Azure AD) data connectors. You are performing a proactive threat hunt for potential data exfiltration via external file sharing services like Dropbox and Google Drive. Your organization blocks these services on managed devices but users can access them from personal devices. You want to detect when users log in to these services from a corporate network using Microsoft Entra ID credentials. You have access to CloudAppEvents, AADSignInEventsBeta, and DeviceNetworkEvents tables in Microsoft Defender XDR advanced hunting. You need to create a hunting query that identifies sign-ins to external file sharing apps from corporate IP ranges. The query should also exclude sign-ins from known good service accounts. Which approach should you take?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Join AADSignInEventsBeta with CloudAppEvents on AccountUpn, filter for app categories containing 'file sharing', and where IPAddress is in the corporate range.
Option B is correct because it joins sign-in events with cloud app events on user principal name and filters by app category (file sharing) and corporate IPs, which directly identifies the behavior. Option A only looks at network events, missing the sign-in context. Option C uses device info, which may not capture personal devices. Option D uses endpoint network events, missing the app context.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
