- A
CloudAppEvents and DeviceNetworkEvents
CloudAppEvents logs activities in cloud apps like SharePoint, including file downloads. DeviceNetworkEvents logs network connections from devices, which can show connections to external services. Joining on device and timestamp allows correlation.
- B
EmailEvents and DeviceNetworkEvents
Why wrong: EmailEvents tracks email interactions, not SharePoint downloads. This would not capture the initial download activity.
- C
DeviceFileEvents and DeviceNetworkEvents
Why wrong: DeviceFileEvents could show file operations, but it does not specify the source (SharePoint). The file download from SharePoint is an HTTP-based event, not a local file creation.
- D
CloudAppEvents and IdentityLogonEvents
Why wrong: IdentityLogonEvents records logon events, not network connections. This would show authentication but not the actual data transfer to external IPs.
Quick Answer
The correct combination is CloudAppEvents and DeviceNetworkEvents. This pairing works because CloudAppEvents captures detailed user activities within cloud applications like SharePoint, including file downloads, while DeviceNetworkEvents logs all network connections from the device, such as outbound traffic to external IPs. By joining these tables on the device ID and timestamp, you can directly correlate a SharePoint download event with a subsequent network connection to a non-corporate cloud storage service like Dropbox, mapping the full exfiltration path. On the SC-200 exam, this question tests your ability to choose the right Advanced Hunting tables for cross-domain investigations, a common scenario in data exfiltration incidents. A frequent trap is selecting CloudAppEvents alone, which shows the download but not the network hop, or using IdentityLogonEvents, which only tracks authentication. Remember the memory tip: “Cloud for the app, Device for the pipe”—CloudAppEvents tells you what was taken, DeviceNetworkEvents tells you where it went.
SC-200 Mitigate threats using Microsoft Defender XDR Practice Question
This SC-200 practice question tests your understanding of mitigate threats using microsoft defender xdr. 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.
An analyst is investigating a data exfiltration incident. They suspect that a user downloaded sensitive files from a SharePoint site and then uploaded them to a non-corporate cloud storage service (e.g., Dropbox) using the same device. Which combination of Advanced Hunting tables should the analyst query to correlate the SharePoint download activity with network connections to external IPs?

Correct answer & explanation
CloudAppEvents and DeviceNetworkEvents
CloudAppEvents logs user activities in cloud apps like SharePoint, including file downloads. DeviceNetworkEvents logs network connections from devices, including connections to external IPs. Combining these tables allows the analyst to correlate the SharePoint download event (from CloudAppEvents) with subsequent network connections to non-corporate cloud storage IPs (from DeviceNetworkEvents) on the same device, directly mapping the exfiltration path.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
IdentityLogonEvents records logon events, not network connections. This would show authentication but not the actual data transfer to external IPs.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often pick DeviceFileEvents (Option C) thinking it logs the SharePoint download locally, but SharePoint downloads are cloud events logged in CloudAppEvents, not local file events.
Trap categories for this question
Command / output trap
DeviceFileEvents could show file operations, but it does not specify the source (SharePoint). The file download from SharePoint is an HTTP-based event, not a local file creation.
Detailed technical explanation
How to think about this question
CloudAppEvents captures Office 365 audit logs, including SharePoint file downloads with fields like FileName, SiteURL, and UserId. DeviceNetworkEvents captures network connections using Windows Filtering Platform (WFP), including destination IP, port, and protocol (TCP/UDP). To correlate, the analyst would join on DeviceId and Timestamp within a window (e.g., 5 minutes) to identify the download event followed by an outbound connection to a known Dropbox IP range (e.g., 162.125.0.0/16). This approach is effective because SharePoint downloads are logged server-side, while network connections are logged client-side, requiring cross-table correlation.
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.
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 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.
