This AZ-400 practice question tests your understanding of configure processes and communications. 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 team uses Azure Repos and wants to enforce that every commit message includes a work item ID. Which policy should you configure?
Repository settings to restrict file paths.
Why wrong: Unrelated to commit messages.
Branch policy to require a minimum comment length.
Why wrong: Does not enforce work item references.
Branch policy to require linked work items.
This policy ensures pull requests link to work items.
Pre-push Git hook.
Why wrong: Client-side hooks are not centrally enforced.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Branch policy to require linked work items.
Option C is correct because Azure Repos branch policies include a 'Require linked work items' setting that enforces every commit in a pull request to be associated with a work item. This ensures commit messages reference a work item ID, as the policy blocks pull requests without linked work items, directly meeting the requirement.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Repository settings to restrict file paths.
Why it's wrong here
Unrelated to commit messages.
Branch policy to require a minimum comment length.
Why it's wrong here
Does not enforce work item references.
Branch policy to require linked work items.
Why this is correct
This policy ensures pull requests link to work items.

Pre-push Git hook.
Why it's wrong here
Client-side hooks are not centrally enforced.
Common exam traps
The trap here is that candidates confuse client-side Git hooks (like pre-push) with server-side branch policies, assuming hooks can enforce requirements centrally, but hooks are optional and can be skipped by developers using --no-verify.
Detailed technical explanation
The 'Require linked work items' policy works by checking that each commit in a pull request has a work item associated via the commit message (e.g., '#123' or 'AB#123') or through the Azure DevOps UI. Under the hood, Azure Repos uses the commit's comment to parse work item references and validates them against the project's work item tracking system. In a real-world scenario, this policy is critical for traceability in regulated environments like healthcare or finance, where every code change must map to a requirement or bug.
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.
