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. A key principle to apply: parentProcessId identifies the process that created the current process.. 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.
A security analyst is using Microsoft 365 Defender advanced hunting to investigate a ransomware incident. The analyst wants to find all processes that were created with a specific parent process ID. Which column in the DeviceProcessEvents table should the analyst use to filter the parent process?
Why wrong: ProcessId identifies the newly created process, not its parent.
B
ParentProcessId
Correct. ParentProcessId holds the ID of the process that created the current process.
C
InitiatingProcessId
Why wrong: InitiatingProcessId represents the process that initiated the action, which is usually the same as the parent process, but for consistency and accuracy, ParentProcessId is the column that directly relates to parent process ID.
D
LogonId
Why wrong: LogonId identifies the user session, not the parent process.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
ParentProcessId
The ParentProcessId column in the DeviceProcessEvents table stores the process ID (PID) of the parent process that created a given process. By filtering on this column, the analyst can identify all child processes spawned by a specific parent, which is critical for tracing ransomware execution chains in advanced hunting queries.
Key principle: ParentProcessId identifies the process that created the current process.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
ProcessId
Why it's wrong here
ProcessId identifies the newly created process, not its parent.
✓
ParentProcessId
Why this is correct
Correct. ParentProcessId holds the ID of the process that created the current process.
Related concept
ParentProcessId identifies the process that created the current process.
✗
InitiatingProcessId
Why it's wrong here
InitiatingProcessId represents the process that initiated the action, which is usually the same as the parent process, but for consistency and accuracy, ParentProcessId is the column that directly relates to parent process ID.
✗
LogonId
Why it's wrong here
LogonId identifies the user session, not the parent process.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing InitiatingProcessId (used in cross-table joins for email or alert context) with ParentProcessId, which is the direct column for parent-child process relationships in DeviceProcessEvents.
Detailed technical explanation
How to think about this question
In Windows, each process has a unique PID and a ParentProcessId that points to the PID of its creator. During ransomware attacks, adversaries often use living-off-the-land binaries (e.g., wscript.exe spawning powershell.exe) — querying DeviceProcessEvents with ParentProcessId allows analysts to trace this lineage. The table also includes command-line arguments, enabling correlation with known malicious parent processes like rundll32.exe or mshta.exe.
KKey Concepts to Remember
ParentProcessId identifies the process that created the current process.
It is essential for building process trees and tracing execution flow.
Used in the DeviceProcessEvents table in Microsoft 365 Defender advanced hunting.
Crucial for investigating attack chains and understanding process relationships.
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
ParentProcessId identifies the process that created the current process.
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. ParentProcessId identifies the process that created the current process. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
