The answer is Microsoft Defender for Identity, Microsoft Sentinel, and Microsoft Entra ID (or Azure AD). Defender for Identity is correct because it monitors on-premises Active Directory for suspicious privileged group changes using behavioral analytics and integrates directly with Microsoft Sentinel. Sentinel serves as the centralized SIEM that ingests logs from both Entra ID via diagnostic settings and on-premises AD via Windows Security Events, enabling custom analytics rules to detect unauthorized changes and trigger automated responses like Logic Apps playbooks. On the AZ-305 exam, this scenario tests your ability to design a hybrid monitoring solution that unifies cloud and on-premises security, often appearing as a multi-service integration question. A common trap is selecting only one monitoring tool, but the design requires all three: Defender for Identity for on-premises detection, Sentinel for aggregation and automation, and Entra ID for cloud-side audit logs. Memory tip: think “D-S-E” — Defender detects, Sentinel orchestrates, Entra logs.
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. 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.
Your company has a hybrid identity environment with Microsoft Entra ID and on-premises Active Directory. You need to design a solution to monitor changes to privileged groups in both directories and ensure that any unauthorized changes trigger an automated response. Which THREE services should you include in the design?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Sentinel
Microsoft Sentinel is correct because it serves as the centralized SIEM (Security Information and Event Management) solution that can ingest logs from both Microsoft Entra ID (via diagnostic settings) and on-premises Active Directory (via Windows Security Events or Azure Monitor Agent). It allows you to create analytics rules that detect unauthorized changes to privileged groups and trigger automated responses, such as playbooks (Logic Apps) or incident creation, ensuring a unified monitoring and response workflow.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
Microsoft Sentinel
Why this is correct
Sentinel can collect logs from both Entra ID and on-premises and automate responses.

✗
Microsoft Purview
Why it's wrong here
Purview is for data governance, not identity monitoring.
✗
Microsoft Entra Identity Protection
Why it's wrong here
Identity Protection focuses on user risk, not group changes.
✗
Group Policy Management Console
Why it's wrong here
Group Policy is for configuration management, not monitoring.
✓
Microsoft Defender for Identity
Why this is correct
Monitors on-premises AD for privilege escalation and group modifications.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Microsoft Purview (data governance) with Microsoft Defender for Cloud Apps (which can monitor group changes in SaaS apps) or assume Entra Identity Protection covers group membership monitoring, but neither Purview nor Identity Protection is designed for auditing or responding to privileged group modifications in hybrid directories.
Detailed technical explanation
How to think about this question
Under the hood, Microsoft Sentinel uses the Azure Monitor Agent or legacy Log Analytics Agent to collect Windows Security Event ID 4732 (a member added to a security-enabled global group) and 4733 (a member removed) from domain controllers, while Entra ID audit logs capture group changes via the AuditLogs table. Sentinel’s analytics rules can be configured with KQL queries that join these sources to detect cross-directory privilege escalation, and automated responses can invoke Microsoft Graph API calls to revert changes or disable accounts—a real-world scenario where a compromised admin adds a user to the 'Domain Admins' group in AD and simultaneously to 'Global Administrator' in Entra ID.

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.
