SC-200 Mitigate threats using Microsoft Sentinel Practice Question
This SC-200 practice question tests your understanding of mitigate threats using microsoft sentinel. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A security operations analyst is creating a scheduled analytics rule in Microsoft Sentinel to detect brute force attempts on Microsoft Entra ID authentication. Which data source is most appropriate for this rule?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SigninLogs
SigninLogs captures user authentication attempts to Microsoft Entra ID, including failed sign-ins, which are essential for detecting brute force attacks. This data source provides detailed properties such as IP address, application, and status codes (e.g., 50076 for invalid password), enabling accurate detection of repeated failed attempts. Azure Activity Logs, Office Activity Logs, and SecurityEvent do not contain Entra ID authentication events.
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.
✗
Azure Activity Logs
Why it's wrong here
Azure Activity Logs record resource management operations, not authentication attempts.
✓
SigninLogs
Why this is correct
SigninLogs contain successful and failed sign-in events needed to detect brute force attacks.
Related concept
Read the scenario before looking for a memorised answer.
✗
Office Activity Logs
Why it's wrong here
Office Activity Logs capture activities in Exchange, SharePoint, etc., not Microsoft Entra ID sign-ins.
✗
SecurityEvent
Why it's wrong here
SecurityEvent collects Windows security events, not Microsoft Entra ID sign-ins.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Activity Logs (control plane) with SigninLogs (authentication plane), assuming all Azure-related logs are in Activity Logs, but Entra ID sign-in events are a separate data source.
Detailed technical explanation
How to think about this question
Under the hood, SigninLogs are ingested via the Azure AD diagnostics settings, which stream authentication events to a Log Analytics workspace. A brute force detection rule typically uses a KQL query like `SigninLogs | where ResultType == 50076 | summarize Count = count() by IPAddress, UserPrincipalName, bin(TimeGenerated, 5m) | where Count > 10` to identify anomalous spikes. In a real-world scenario, attackers often use distributed IPs, so the rule may need to aggregate by user principal name and time window to avoid false negatives.
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.
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.
