The answer is the DeviceProcessEvents table. This is the correct choice because it captures every process creation event on a device, including the full command-line arguments in the ProcessCommandLine column, which is exactly what an analyst needs to see when investigating a malicious script’s execution. On the Microsoft Security Operations Analyst SC-200 exam, this question tests your ability to map investigative goals to the correct Advanced Hunting schema—a core skill for incident response. A common trap is confusing DeviceProcessEvents with DeviceEvents, which logs other system events but not process command lines. Remember: if you need to see what arguments were passed when a process started, you always query DeviceProcessEvents. A simple memory tip is “Process for the command line, Events for everything else.”
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.
In Microsoft 365 Defender, an analyst is investigating an incident involving a malicious script. The analyst wants to see the command-line arguments executed by the script on a specific device. Which Advanced Hunting table should the analyst query?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
DeviceProcessEvents
The DeviceProcessEvents table in Advanced Hunting captures process creation events, including the command-line arguments used to execute a process. Since the analyst needs to see the command-line arguments executed by a malicious script on a specific device, querying DeviceProcessEvents is the correct approach because it records the ProcessCommandLine column for each process creation event.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
DeviceProcessEvents
Why this is correct
This table logs process creation events and includes the command line, allowing the analyst to see executed arguments.

✗
DeviceNetworkEvents
Why it's wrong here
DeviceNetworkEvents contains network connection data, not process command lines.
✗
DeviceFileEvents
Why it's wrong here
DeviceFileEvents logs file creation and modification events, not process command lines.
✗
DeviceEvents
Why it's wrong here
DeviceEvents includes various events like scheduled tasks and WMI, but not the command-line arguments of processes.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse DeviceProcessEvents with DeviceEvents, assuming the latter includes all process-related data, but DeviceEvents is a catch-all for miscellaneous events and does not contain the ProcessCommandLine column.
Trap categories for this question
Command / output trap
DeviceNetworkEvents contains network connection data, not process command lines.
Detailed technical explanation
How to think about this question
The DeviceProcessEvents table is populated by Microsoft Defender for Endpoint's sensor, which hooks into the Windows kernel to capture process creation via ETW (Event Tracing for Windows) and the CreateProcess API. The ProcessCommandLine column can include sensitive data like passwords or tokens if passed as arguments, so analysts must handle it carefully. In a real-world scenario, querying this table with a filter on DeviceName and Timestamp can reveal the exact command-line invocation of a malicious script, such as powershell.exe -EncodedCommand <base64>.

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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.

Variation 1. A security analyst is investigating an incident in Microsoft 365 Defender that involves a user who clicked a phishing link. The analyst wants to find all processes executed on the user's device immediately after the email was opened. Which advanced hunting table should the analyst query to obtain process creation events with timestamps relative to the email event?
medium
✓ A.DeviceProcessEvents
B.EmailEvents
C.DeviceNetworkEvents
D.IdentityLogonEvents
Why A: DeviceProcessEvents is the correct table because it stores process creation events (including image name, command line, and timestamp) for all devices onboarded to Microsoft Defender for Endpoint. By querying this table with a time range starting immediately after the email event (identified from EmailEvents), the analyst can correlate the phishing click with subsequent process executions on the user's device.
