The answer is a KQL query that joins SigninLogs with AuditLogs on user principal name and times within a short window. This approach is correct because correlating logins and password resets with KQL for credential theft requires linking two distinct event types across separate tables—the login from an unusual location in SigninLogs and the password reset action in AuditLogs—using a join operator to establish a temporal and user-based relationship. On the SC-200 exam, this tests your ability to perform multi-table hunting in Microsoft Sentinel, a common scenario where attackers use a compromised account to reset another user’s credentials; the trap is choosing a single-table query (Option A), which cannot correlate cross-table events, or a watchlist, which is static and not suited for real-time correlation. Remember the memory tip: “Join the logs to catch the crooks”—if you need to link two different event types, a join is your only path to detection.
SC-200 Perform threat hunting Practice Question
This SC-200 practice question tests your understanding of perform threat hunting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 security team uses Microsoft Sentinel to hunt for signs of credential theft. They want to detect when a user account has been used to log in from an unusual location and then immediately performs a password reset for another user. Which hunting approach is most effective for this scenario?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Write a KQL query that joins SigninLogs with AuditLogs on user principal name and times within a short window
Option B (KQL query using join between two tables) is correct because it allows correlating login events from one table with password reset events from another table, combining the two conditions. Option A (single table) cannot correlate two different event types. Option C (watchlist) is for static data, not real-time correlation. Option D (playbook) is for automated response, not hunting.
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.
✗
Use a Microsoft Sentinel playbook to automatically flag any password reset
Why it's wrong here
Playbooks are for automation, not hunting.
✓
Write a KQL query that joins SigninLogs with AuditLogs on user principal name and times within a short window
Why this is correct
This correlates the two events to detect the sequence of unusual login followed by password reset.
Clue confirmation
The clue word "immediately / without restart" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Search the SigninLogs table for logins from unusual locations
Why it's wrong here
This only addresses one part of the scenario and does not correlate with password resets.
✗
Create a watchlist of known unusual locations and use it in a query against AuditLogs
Why it's wrong here
Watchlists are static and do not correlate different event types.
Common exam traps
Common exam trap: answer the scenario, not the keyword

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.

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.
