AZ-400 Develop a security and compliance plan Practice Question
This AZ-400 practice question tests your understanding of develop a security and compliance plan. 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.
Your organization uses Microsoft Defender XDR for security monitoring. You need to configure an alert that fires whenever a user with high privileges (e.g., Project Collection Administrators) is added to an Azure DevOps group. What is the most efficient approach?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a custom detection rule in Microsoft Defender XDR using the Azure DevOps identity provider logs
Option C (Create a custom detection rule in Microsoft Defender XDR using the Azure DevOps identity provider logs) is correct because Defender XDR can ingest Azure DevOps audit logs and create custom detections for specific activities. Option A is not efficient for real-time alerting. Option B is for Azure, not Azure DevOps. Option D is for compliance, not real-time alerting.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Set up a Microsoft Purview compliance policy for Azure DevOps
Why it's wrong here
Purview is for data governance and compliance, not real-time security alerts.
✗
Run a weekly Azure DevOps audit log query manually
Why it's wrong here
Manual queries are not efficient and do not provide real-time alerts.
✓
Create a custom detection rule in Microsoft Defender XDR using the Azure DevOps identity provider logs
Why this is correct
Defender XDR can ingest Azure DevOps audit logs and trigger alerts on specific events.
Related concept
Authentication checks who the user is.
✗
Configure a Log Analytics workspace with Azure Activity Logs
Why it's wrong here
Azure Activity Logs do not include Azure DevOps audit events directly.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
→Do not assume successful login means full administrative access.
→Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
→Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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.
