Quick Answer
The answer is SigninLogs, SecurityEvent, and AADNonInteractiveUserSignInLogs, as these three data sources in Microsoft Sentinel provide the authentication telemetry necessary for threat hunting to detect unusual authentication patterns. SigninLogs from Microsoft Entra ID capture interactive user sign-ins, including location, IP, and application details, while SecurityEvent (Windows Event Log) records local logon events like Event ID 4624, which is critical for spotting anomalous workstation or server access. AADNonInteractiveUserSignInLogs fill a crucial gap by logging service-side or script-based sign-ins that often bypass interactive logs, making them essential for detecting credential misuse in automated processes. On the SC-200 exam, this question tests your ability to distinguish authentication-specific sources from audit or network logs—a common trap is confusing OfficeActivity (which tracks user actions, not auth) or CommonSecurityLog (for firewall events) with actual sign-in data. Remember the mnemonic: “Three S’s for Sign-ins—SigninLogs, SecurityEvent, and Service-side (AADNonInteractive).”
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 data sources can be used in Microsoft Sentinel for threat hunting to detect unusual authentication patterns? (Choose three.)
SecurityEvent (Windows Event Logs)
Contains logon events (Event ID 4624, 4625).
AADNonInteractiveUserSignInLogs
Contains non-interactive sign-ins.
CommonSecurityLog
Why wrong: Contains network device logs, not authentication.
OfficeActivity (Office 365)
Why wrong: Contains audit logs for Office 365, not authentication events.
SigninLogs (Microsoft Entra ID)
Contains interactive user sign-ins.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
SecurityEvent (Windows Event Logs)
Option A is correct because SigninLogs from Microsoft Entra ID contain authentication data. Option B is correct because SecurityEvent (Windows Event Log) contains logon events. Option D is correct because AADNonInteractiveUserSignInLogs contain non-interactive sign-ins. Option C is wrong because OfficeActivity contains audit logs, not authentication. Option E is wrong because CommonSecurityLog is for network devices, not authentication.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
SecurityEvent (Windows Event Logs)
Why this is correct
Contains logon events (Event ID 4624, 4625).
Related concept
Static NAT maps one inside address to one outside address.
AADNonInteractiveUserSignInLogs
Why this is correct
Contains non-interactive sign-ins.
Related concept
Static NAT maps one inside address to one outside address.
CommonSecurityLog
Why it's wrong here
Contains network device logs, not authentication.
OfficeActivity (Office 365)
Why it's wrong here
Contains audit logs for Office 365, not authentication events.
SigninLogs (Microsoft Entra ID)
Why this is correct
Contains interactive user sign-ins.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
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.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SC-200 NAT questions on configuration and troubleshooting.
