SC-200 Mitigate threats using Microsoft Defender XDR Practice Question
This SC-200 practice question tests your understanding of mitigate threats using microsoft defender xdr. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: identityLogonEvents captures authentication events for both cloud and on-premises identities.. 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 analyst is using advanced hunting in Microsoft 365 Defender to investigate a potential brute-force attack against an on-premises Exchange server. The analyst wants to find authentication failures from a specific IP address. Which table should the analyst query?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
IdentityLogonEvents
IdentityLogonEvents is the correct table because it captures authentication events from Microsoft Defender for Identity, including failed logon attempts against on-premises Active Directory and Exchange servers. This table specifically logs interactive and non-interactive logon failures with source IP details, making it ideal for investigating brute-force attacks from a specific IP address.
Key principle: IdentityLogonEvents captures authentication events for both cloud and on-premises identities.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
EmailEvents
Why it's wrong here
EmailEvents contains email delivery and response actions, not authentication logs.
✓
IdentityLogonEvents
Why this is correct
IdentityLogonEvents collects authentication events from both cloud and on-premises, including Exchange servers integrated with Active Directory.
Related concept
IdentityLogonEvents captures authentication events for both cloud and on-premises identities.
✗
DeviceLogonEvents
Why it's wrong here
DeviceLogonEvents logs local and remote logons to devices, not application-specific authentication.
✗
CloudAppEvents
Why it's wrong here
CloudAppEvents records activities in cloud apps, not on-premises Exchange logins.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse DeviceLogonEvents (endpoint-focused) with IdentityLogonEvents (identity-focused), forgetting that on-premises Exchange authentication is handled by Active Directory and monitored by Defender for Identity, not by endpoint sensors.
Detailed technical explanation
How to think about this question
IdentityLogonEvents is populated by Microsoft Defender for Identity sensors that monitor on-premises Active Directory traffic using Windows Event ID 4625 (failed logon) and other authentication-related events. The table includes fields like `LogonType`, `AccountUpn`, and `IPAddress`, allowing analysts to filter by source IP and time range. In a real-world scenario, an analyst might use a query like `IdentityLogonEvents | where Timestamp > ago(1h) | where IPAddress == '10.0.0.5' | where ActionType == 'LogonFailed'` to pinpoint brute-force attempts.
KKey Concepts to Remember
IdentityLogonEvents captures authentication events for both cloud and on-premises identities.
It includes authentication attempts against on-premises Exchange servers integrated with Active Directory.
The table provides details like user, IP address, application, and logon outcome (success/failure).
It is crucial for investigating identity-related attacks like brute-force or credential stuffing.
TExam Day Tips
→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
IdentityLogonEvents captures authentication events for both cloud and on-premises identities.
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.
