The answer is to correlate process creation events with file modification events, inspect scheduled tasks, and check for service installation. These three actions are correct because ransomware typically executes a malicious process that rapidly encrypts files, so linking process creation to file modification events reveals the encryption pattern, while scheduled tasks and service installations are common persistence mechanisms ransomware uses to survive reboots and maintain access. On the Microsoft Security Operations Analyst SC-200 exam, this scenario tests your ability to use advanced hunting in Microsoft Defender XDR to trace the lateral movement and impact of ransomware on endpoints, not on cloud services or user accounts. A common trap is selecting mailbox audit logs or password change reviews, which are irrelevant for endpoint-based ransomware outbreaks. Remember the memory tip: “Process, Persist, Service” — focus on the process that modifies files, the scheduled task that persists, and the service that installs to anchor the attack.
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.
Which THREE actions should a threat hunter take when using Microsoft Defender XDR advanced hunting to investigate a potential ransomware outbreak? (Select THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check for service installation events that mimic system services.
Options A, C, and E are correct because correlating process creation with file modifications, inspecting scheduled tasks, and checking for service installation are key steps to identify ransomware behavior. Option B is wrong because reviewing mailbox audit logs is not relevant for ransomware on endpoints. Option D is wrong because reviewing password changes is not directly related to ransomware.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Review mailbox audit logs for email forwarding rules.
Why it's wrong here
Email forwarding is not typical ransomware behavior.
✓
Inspect scheduled tasks for persistence mechanisms.
Why this is correct
Ransomware may create scheduled tasks for persistence.

✓
Correlate process creation events with file modification events.
Why this is correct
Ransomware often creates processes and modifies files; correlation helps identify malicious activity.

Review password change events for service accounts.
Why it's wrong here
Password changes are not directly related to ransomware.
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.

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.
