Quick Answer
The answer is Microsoft Entra ID Audit Logs. These logs capture every administrative action and configuration change within the Entra ID tenant, including role assignments, group membership updates, and permission grants, making them essential for real-time monitoring in Sentinel. By streaming these logs, you enable immediate alerting on critical changes, directly satisfying the security team’s requirement for logging all administrative actions in a hybrid identity environment. On the Microsoft Cybersecurity Architect exam, this tests your understanding of which native Entra ID data source provides the necessary audit trail for security operations, often appearing in scenario-based questions where candidates mistakenly choose Sign-in Logs or Azure Activity Logs—but only Audit Logs cover administrative changes. A common trap is confusing “real-time monitoring” with diagnostic settings; remember that Audit Logs are the only source that records who did what and when. Memory tip: “Audit for actions, Sign-in for access.”
This SC-100 practice question tests your understanding of design solutions that align with security best practices and priorities. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
You are designing a security solution for a multinational organization that uses Microsoft Entra ID. They have a hybrid identity environment with Active Directory on-premises. The security team requires that all administrative actions in Microsoft Entra ID are logged and monitored in real-time with alerts for critical changes. Which two data sources should you stream to Microsoft Sentinel?
Microsoft Entra ID Sign-in Logs
Sign-in logs provide real-time authentication activity.
Microsoft Entra ID Audit Logs
Audit logs record all changes to directory objects.
Azure Activity Log
Why wrong: Azure Activity Log is for Azure resource operations, not directory.
Microsoft Entra ID Provisioning Logs
Why wrong: Provisioning logs are not real-time.

Correct answer & explanation
Microsoft Entra ID Sign-in Logs
Microsoft Entra ID Audit Logs contain records of all administrative changes and configuration modifications within the tenant, such as user role assignments, group membership updates, and application permission grants. Streaming these logs to Microsoft Sentinel enables real-time monitoring and alerting for critical administrative actions, meeting the security team's requirement for logging and alerting on all administrative actions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Azure Activity Log
Why it's wrong here
Azure Activity Log is for Azure resource operations, not directory.
Microsoft Entra ID Provisioning Logs
Why it's wrong here
Provisioning logs are not real-time.
Common exam traps
The trap here is that candidates often confuse Azure Activity Log (which covers Azure resource operations) with Microsoft Entra ID Audit Logs (which cover directory administrative actions), leading them to select Azure Activity Log instead of the correct Entra ID Audit Logs.
Detailed technical explanation
Microsoft Entra ID Audit Logs use a REST API (beta or v1.0) to expose directory changes with properties like 'activityDateTime', 'activityDisplayName', and 'initiatedBy' (user or service principal). In a hybrid environment, on-premises AD changes replicated via Azure AD Connect are not captured in these logs; only direct changes to the Entra ID cloud directory are logged. Real-time streaming to Sentinel uses the Microsoft Entra ID connector with a diagnostic setting, which can send logs within minutes of the event.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
