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. 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.
You are using Microsoft Defender for Cloud to secure Azure Pipelines. You need to receive alerts when a pipeline run uses a service principal with excessive permissions. Which feature should you enable?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable Microsoft Defender for Cloud's identity and access monitoring.
Option B is correct because Defender for Cloud's identity and access monitoring can alert on over-privileged service principals used in pipelines. Option A is wrong because audit logs alone do not generate alerts. Option C is wrong because conditional access policies are for user sign-ins, not service principals in pipelines. Option D is wrong because Azure Policy does not generate real-time alerts for pipeline runs.
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.
✗
Enable Azure DevOps audit logs and review them manually.
Why it's wrong here
Manual review is not scalable and does not provide alerts.
✗
Create an Azure Policy to deny over-privileged service principals.
Why it's wrong here
Azure Policy can enforce compliance but does not generate real-time alerts.
✓
Enable Microsoft Defender for Cloud's identity and access monitoring.
Why this is correct
This provides alerts on risky permissions and usage.
Related concept
Authentication checks who the user is.
✗
Configure Microsoft Entra ID Conditional Access policies.
Why it's wrong here
Conditional Access applies to users, not service principals in pipelines.
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.
