The answer is the File entity page. This page is the correct destination because it serves as the single pane of glass for file-centric investigations, aggregating telemetry from Microsoft Defender for Endpoint, Office 365, and other XDR sources to display a file’s prevalence across devices and users, its global reputation based on Microsoft’s cloud threat intelligence, and a timeline of related incidents. On the SC-200 exam, this concept tests your understanding of how Microsoft 365 Defender centralizes file-level data for efficient triage; a common trap is confusing the File entity page with the Device or User entity pages, which focus on different pivots. For a memory tip, think of the File entity page as the “file’s passport”—it shows where the file has been (prevalence), its global standing (reputation), and its criminal record (incidents).

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 file that was detected as malicious on several devices. In Microsoft 365 Defender, where can the analyst find information about the file's prevalence, global reputation, and related incidents?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
File entity page
The File entity page in Microsoft 365 Defender aggregates file-level telemetry, including prevalence (number of devices/users), global reputation (Microsoft's cloud-based threat intelligence), and a timeline of related incidents. This page is the single pane of glass for file-centric investigations, pulling data from Microsoft Defender for Endpoint, Office 365, and other XDR sources.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Device entity page
Why it's wrong here
The device entity page focuses on device-specific information, not file prevalence.
✗
User entity page
Why it's wrong here
The user entity page shows user-related activities and alerts, not file details.
✗
Email entity page
Why it's wrong here
The email entity page provides email-specific details, not file reputation across devices.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Microsoft often tests the distinction between entity pages by making candidates confuse the File entity page (which shows prevalence and reputation) with the Device entity page (which shows device-specific alerts but not file-level global data).
Trap categories for this question
Command / output trap
The user entity page shows user-related activities and alerts, not file details.
Detailed technical explanation
How to think about this question
Under the hood, the File entity page queries the Microsoft Defender XDR data lake, which ingests telemetry from endpoints, email, and cloud apps. Prevalence is calculated from the number of unique devices or users that have observed the file hash, while global reputation leverages Microsoft's threat intelligence graph, including signals from over 8 trillion daily security signals. Related incidents are correlated via the incident ID field, linking the file to any associated alerts or automated investigations.

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 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.
