SC-200 Respond to security incidents Practice Question
This SC-200 practice question tests your understanding of respond to security incidents. 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
// KQL query in Microsoft Sentinel
let TimeRange = 1h;
IdentityLogonEvents
| where Timestamp > ago(TimeRange)
| where Application == "Microsoft Entra ID"
| summarize LogonAttempts = count() by UserPrincipalName, IPAddress, ResultType
| where ResultType == "Failed"
| where LogonAttempts > 5
```
Refer to the exhibit. The KQL query runs in Microsoft Sentinel and returns no results. The analyst expects to see failed logon attempts. What is the most likely reason?
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
// KQL query in Microsoft Sentinel
let TimeRange = 1h;
IdentityLogonEvents
| where Timestamp > ago(TimeRange)
| where Application == "Microsoft Entra ID"

| where ResultType == "Failed"
| where LogonAttempts > 5
```
A
The Application filter is incorrect.
Why wrong: Microsoft Entra ID is a valid application name in IdentityLogonEvents.
B
The ResultType field does not exist in IdentityLogonEvents.
IdentityLogonEvents uses 'Result' or 'LogonResult' not 'ResultType'. Using a non-existent field causes no results.
C
The summarize operator is misused.
Why wrong: The summarize syntax is correct; it groups by user, IP, and result.
D
The TimeRange variable is too short.
Why wrong: 1 hour is reasonable; if there were failed logons in the last hour, they would appear.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The ResultType field does not exist in IdentityLogonEvents.
The query filters on ResultType == 'Failed', but the field is likely named 'Result' or uses different values like 'Failure'. Also, the table 'IdentityLogonEvents' may not exist; it might be 'AADSignInEventsBeta' or similar. But the most common issue is incorrect field name for result type.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.

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.
