- A
SigninLogs | where TimeGenerated > ago(24h) | where UserPrincipalName == "user@domain.com" | summarize count() by IPAddress
SigninLogs contains user sign-in events with IP addresses.
- B
SecurityEvent | where TimeGenerated > ago(24h) | where TargetUserName == "user@domain.com" | summarize count() by IpAddress
Why wrong: SecurityEvent is for on-premises Windows events, not cloud sign-ins.
- C
AuditLogs | where TimeGenerated > ago(24h) | where InitiatedBy.user.userPrincipalName == "user@domain.com" | summarize count() by IPAddress
Why wrong: AuditLogs contains admin audit events, not user sign-ins.
- D
CommonSecurityLog | where TimeGenerated > ago(24h) | where SourceUserID == "user@domain.com" | summarize count() by SourceIP
Why wrong: CommonSecurityLog is for network devices.
Quick Answer
The correct KQL query for finding sign-in events from multiple IP addresses in Microsoft Sentinel is SigninLogs | where TimeGenerated > ago(24h) | where UserPrincipalName == "user@domain.com" | summarize count() by IPAddress. This works because the SigninLogs table captures all cloud-based user authentication events, and the summarize operator groups those events by distinct IP addresses, allowing the threat hunter to quickly identify anomalous logins from different locations. On the SC-200 exam, this question tests your ability to distinguish between log sources: SigninLogs is for user sign-ins, AuditLogs tracks admin changes, SecurityEvent covers on-premises Windows logs, and CommonSecurityLog handles network appliance data. A common trap is confusing AuditLogs with sign-in data, so remember that “sign-in” always points to SigninLogs. For a quick memory tip, think “SigninLogs for sign-ins, AuditLogs for admins.”
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 investigating a potential compromise involving a user account that has been used to sign in from multiple locations within a short time. The hunter wants to use Microsoft Sentinel to find all sign-in events for that user from different IP addresses in the last 24 hours. Which KQL query should be used?
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
SigninLogs | where TimeGenerated > ago(24h) | where UserPrincipalName == "user@domain.com" | summarize count() by IPAddress
Option D is correct because SigninLogs contains user sign-in data and the query groups by UserPrincipalName and IP address. Option A is wrong because AuditLogs contains administrative actions, not sign-ins. Option B is wrong because SecurityEvent is for Windows events, not cloud sign-ins. Option C is wrong because CommonSecurityLog is for network devices.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
