The answer is that Microsoft Entra ID Protection is not enabled for the tenant. This is the most likely cause when a KQL query returns no results from the IdentityLogonEvents table, because that table is exclusively populated by Entra ID Protection’s risk detection engine. Without the service enabled, the table remains empty regardless of correct syntax, column names, or time range, so the query will always yield zero rows. On the AZ-305 exam, this scenario tests your understanding of data source dependencies in Microsoft Sentinel—specifically, that certain tables require specific Azure services to be active before they contain logs. A common trap is to assume the query is wrong or that permissions are missing, but the real issue is the missing upstream service. Memory tip: think of IdentityLogonEvents as a “protection-only” table—if Entra ID Protection is off, the table is a ghost town.
AZ-305 Practice Question: Design identity, governance, and monitoring solutions
This AZ-305 practice question tests your understanding of design identity, governance, and monitoring solutions. 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.
Exhibit
{
"query": "SigninLogs | where TimeGenerated > ago(1h) | where RiskLevelDuringSignIn == 'high' | project UserPrincipalName, Location, RiskLevelDuringSignIn"
}
Refer to the exhibit. You are reviewing a KQL query in Microsoft Sentinel. The query returns no results. Which is the most likely cause?
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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Entra ID Protection is not enabled for the tenant
The KQL query references the 'IdentityLogonEvents' table, which is populated by Microsoft Entra ID Protection. If Entra ID Protection is not enabled, this table will contain no data, causing the query to return zero results even if the syntax, column names, and time range are correct.
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.
✗
The syntax is invalid because where clause should use == instead of ==
Why it's wrong here
The syntax is correct.
✓
Microsoft Entra ID Protection is not enabled for the tenant
Why this is correct
Without Identity Protection, RiskLevelDuringSignIn may be null.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

Read the scenario before looking for a memorised answer.
✗
The column names are incorrect
Why it's wrong here
The column names are valid for SigninLogs.
✗
The time range is too short
Why it's wrong here
The query uses ago(1h), which is valid.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume a KQL query returning no results is due to syntax errors or column name typos, but the real issue is a missing prerequisite service (Entra ID Protection) that populates the referenced table.
Detailed technical explanation
How to think about this question
The IdentityLogonEvents table is part of the Microsoft Entra ID Protection data connector, which requires an active Entra ID P2 license and the protection service to be enabled. When Entra ID Protection is disabled, the connector stops ingesting risk-related logon events, leaving the table empty. This is a common misconfiguration where administrators assume the table is always populated, but it depends on the licensing and feature activation.

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
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.
