The answer is to use AADSignInEventsBeta instead of IdentityLogonEvents when querying Azure Portal logon events in Microsoft Sentinel. IdentityLogonEvents is a table sourced from Microsoft Defender for Identity, which captures authentication events from on-premises domain controllers, not cloud-based Azure Portal sign-ins. Azure Portal logons are cloud authentication events stored exclusively in the AADSignInEventsBeta table, which records interactive sign-ins to Azure services. On the SC-200 exam, this distinction tests your understanding of data source mapping across Microsoft’s security products—a common trap is assuming IdentityLogonEvents covers all logon types because of its name. Remember the memory tip: “Identity is on-prem, AAD is cloud.”
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.
Exhibit
Refer to the exhibit.
```kql
let TargetUser = 'jdoe@contoso.com';
IdentityLogonEvents
| where Timestamp > ago(7d)
| where AccountUpn == TargetUser
| where Application == 'Azure Portal'
| summarize LogonCount = count() by IPAddress, Country
| where LogonCount > 10
```
Refer to the exhibit. You are investigating a user account that shows multiple logons to the Azure Portal from various countries within a short time. The query returns no results despite known logons. What is the most likely issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Refer to the exhibit.
```kql
let TargetUser = 'jdoe@contoso.com';
IdentityLogonEvents
| where Timestamp > ago(7d)
| where AccountUpn == TargetUser
| where Application == 'Azure Portal'
| summarize LogonCount = count() by IPAddress, Country
| where LogonCount > 10
```
A
The Timestamp filter should be Timestamp > ago(7d) but instead it's written incorrectly.
Why wrong: The filter is correct syntax.
B
The AccountUpn field is not present in IdentityLogonEvents.
Why wrong: AccountUpn does exist in IdentityLogonEvents.
C
The Application filter should be 'Azure Portal' in a different case.
Why wrong: KQL is case-insensitive.
D
IdentityLogonEvents does not contain Azure Portal logon events; use AADSignInEventsBeta instead.
IdentityLogonEvents is for on-premises AD logons, not cloud.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
IdentityLogonEvents does not contain Azure Portal logon events; use AADSignInEventsBeta instead.
Option A is correct because IdentityLogonEvents is a table in Microsoft Defender for Identity (now part of Microsoft Defender XDR), but it logs events from domain controllers, not Azure Portal logons. Azure Portal logons are in AADSignInEventsBeta. Option B is incorrect because the query uses Timestamp. Option C is incorrect because AccountUpn is a valid field. Option D is incorrect because the filter on Application is valid.
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 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.
