- A
DeviceProcessEvents | where TimeGenerated > ago(7d) | where FileName == "powershell.exe" | where ProcessCommandLine contains "-enc" | project Timestamp, DeviceName, ProcessCommandLine
Why wrong: This looks for PowerShell, not certutil.exe.
- B
DeviceProcessEvents | where TimeGenerated > ago(7d) | where FileName == "mshta.exe" | where ProcessCommandLine contains "http" | project Timestamp, DeviceName, ProcessCommandLine
Why wrong: This looks for mshta.exe, not certutil.exe.
- C
DeviceProcessEvents | where TimeGenerated > ago(7d) | where FileName == "certutil.exe" | where ProcessCommandLine contains "-urlcache" or ProcessCommandLine contains "-split" | project Timestamp, DeviceName, ProcessCommandLine
certutil.exe with -urlcache is commonly used to download files.
- D
DeviceProcessEvents | where TimeGenerated > ago(7d) | where FileName == "wscript.exe" | where ProcessCommandLine contains "http" | project Timestamp, DeviceName, ProcessCommandLine
Why wrong: This looks for wscript.exe, not certutil.exe.
Quick Answer
The correct KQL query for detecting certutil.exe downloads is the one that filters DeviceProcessEvents for the process name and command-line arguments like -urlcache or -split within the last seven days. This works because certutil.exe, a legitimate Windows binary, is often abused as a living-off-the-land binary (LOLBin) to download payloads from the internet, and its -urlcache and -split flags are the specific parameters used for file retrieval. On the Microsoft Security Operations Analyst SC-200 exam, this scenario tests your ability to distinguish between common LOLBins and their misuse patterns, with a common trap being to confuse certutil.exe with mshta.exe, wscript.exe, or powershell.exe—each of which serves different attack vectors. A helpful memory tip is to associate “certutil” with “certificate utility” but remember that its -urlcache switch is the red flag for downloads, not its certificate functions.
SC-200 Perform threat hunting Practice Question
This SC-200 practice question tests your understanding of perform threat hunting. 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.
A threat hunter is analyzing a potential advanced persistent threat (APT) that uses living-off-the-land binaries (LOLBins) like certutil.exe to download payloads. The hunter wants to find instances where certutil.exe was used to download files from the internet in the last week. Which KQL query in Microsoft Sentinel would be most effective?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
DeviceProcessEvents | where TimeGenerated > ago(7d) | where FileName == "certutil.exe" | where ProcessCommandLine contains "-urlcache" or ProcessCommandLine contains "-split" | project Timestamp, DeviceName, ProcessCommandLine
Option A is correct because it looks for certutil.exe with a URL parameter in the command line. Option B is wrong because it looks for mshta.exe. Option C is wrong because it looks for wscript.exe. Option D is wrong because it looks for powershell.exe.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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
How to think about this question
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.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
