The answer is to review UEBA anomalies for unusual logon times or locations, multiple failed attempts, and unusual application access. Microsoft Sentinel UEBA, or User and Entity Behavior Analytics, establishes a baseline of normal user activity and then surfaces deviations that signal a compromised identity, such as logins from atypical geographies or off-hours access patterns. On the SC-200 exam, this question tests your ability to distinguish identity-focused hunting from network or infrastructure monitoring; common traps include selecting firewall change investigations or DNS log reviews, which belong to separate threat vectors. Remember the memory tip: “UEBA hunts the user, not the network”—if the action doesn’t involve a user’s behavior or access anomalies, it’s likely the wrong choice for compromised identity hunting.
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 are recommended when conducting a threat hunt for compromised identities using Microsoft Sentinel UEBA?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Search for access to applications the user does not normally use
UEBA is used to detect anomalous behavior; focusing on unusual logon times, multiple failed attempts, and unusual application access are key indicators of compromised identities. Option C (investigating firewall changes) is more for network security. Option E (reviewing DNS logs) is for network anomalies.
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.
✓
Search for access to applications the user does not normally use
Why this is correct
Unusual application access can indicate account takeover.
Related concept
Read the scenario before looking for a memorised answer.
✗
Query DNS logs for unusual domain resolutions
Why it's wrong here
DNS logs are more relevant for command-and-control detection, not identity compromise.
✓
Look for multiple failed logon attempts followed by a successful one
Why this is correct
This pattern suggests a brute-force attack that succeeded.

✗
Investigate changes to firewall rules
Why it's wrong here
Firewall changes are not directly related to identity compromise.
✓
Review UEBA anomalies for unusual logon times or locations
Why this is correct
Anomalous logon patterns are a classic sign of compromise.

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

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
