Quick Answer
The answer is the File page in Microsoft Defender for Endpoint. This is the correct feature because it is specifically designed to investigate file prevalence across devices, providing a centralized view of how widely a file has been detected, a detailed device list, and all related events such as alerts and behaviors tied to that file. On the MS-102 exam, this question tests your understanding of MDE’s investigation surfaces and their distinct purposes; a common trap is confusing the File page with the Device page, which only shows data for a single endpoint, or the Alert page, which focuses on incident-level notifications rather than file-level distribution. To remember this, think of the File page as the “spreadsheet” of file sightings—it tells you where and how often a file appears, while other pages give you a single point of view.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
