The answer is to initiate the Collect investigation package action from the device’s entity page. This is correct because the Collect investigation package action is specifically designed to retrieve a ZIP file containing forensic data—including suspicious files, registry keys, and memory dumps—from an isolated device without requiring interactive access or network connectivity. On the Microsoft Security Operations Analyst SC-200 exam, this scenario tests your understanding of how automated investigation and response (AIR) isolation works alongside manual collection methods; a common trap is confusing this with initiating a live response session, which is blocked once a device is isolated. Remember that isolation locks down interactive tools, but the Collect investigation package action remains available because it uses a pre-signed command that the device processes locally. Memory tip: think “Isolated? Collect the package—no interactive access required.”
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 organization uses Microsoft 365 Defender. A security analyst is investigating a malware incident on a user's device. The automated investigation and response (AIR) has already isolated the device from the network. The analyst now needs to collect a copy of a specific suspicious file from the device for further analysis. Which action should the analyst initiate from the device's entity page?
This action gathers a package of forensic data including files, processes, and registries for analysis.
B
Run antivirus scan
Why wrong: Running a scan will detect threats but does not collect specific files for offline analysis.
C
Restrict app execution
Why wrong: This action limits which applications can run on the device, not collect files.
D
Initiate a live response session
Why wrong: Live response is an interactive session; the question asks for a direct action to collect a specific file, which is more aligned with the collect investigation package action.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Collect investigation package
Option A is correct because the 'Collect investigation package' action on the device entity page in Microsoft 365 Defender gathers a ZIP file containing the device's forensic data, including specific suspicious files, registry keys, and memory dumps. This is the designed method for retrieving a copy of a file for offline analysis without requiring interactive access, and it works even after AIR has isolated the device.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Live response is an interactive session; the question asks for a direct action to collect a specific file, which is more aligned with the collect investigation package action.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'Initiate a live response session' as the go-to for file collection, but fail to remember that live response requires an active network connection to the device, which is blocked when AIR has isolated the device from the network.
Detailed technical explanation
How to think about this question
The 'Collect investigation package' action leverages the Microsoft Defender for Endpoint sensor to gather data from the device and upload it to the cloud backend, where it is packaged as a .zip file accessible from the investigation package tab. This process uses the same secure channel that AIR uses for commands, so it bypasses network isolation restrictions because the device can still communicate outbound to Microsoft cloud services. In a real-world scenario, if a file is suspected of being a polymorphic malware variant, collecting the package allows the analyst to extract the exact binary for sandbox analysis without risking lateral movement.

→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

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.
