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.
Your organization is implementing a security compliance plan for Azure DevOps. Which TWO actions should you take to ensure that only authorized users can modify build pipelines?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure branch policies to require reviews for changes to pipeline YAML files
Options C and E are correct because pipeline permissions in Azure DevOps control who can edit pipelines, and branch policies protect the pipeline definition. Option A is wrong because PATs are for authentication, not authorization. Option B is wrong because OIDC is for authentication. Option D is wrong because audit logs track changes but don't prevent unauthorized modifications.
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.
✗
Require all users to use Personal Access Tokens (PATs)
Why it's wrong here
PATs are for authentication, not authorization to edit pipelines.
✓
Configure branch policies to require reviews for changes to pipeline YAML files
Why this is correct
Branch policies require approvals for changes to pipeline definitions.
Related concept
Authentication checks who the user is.
✓
Set pipeline permissions to restrict editing to specific security groups
Why this is correct
This controls who can modify pipelines.
Related concept
Authentication checks who the user is.
✗
Enable audit logging for all pipeline changes
Why it's wrong here
Audit logs track changes but don't prevent unauthorized modifications.
✗
Enable OpenID Connect (OIDC) for pipeline authentication
Why it's wrong here
OIDC is for authentication without secrets.
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.
