- A
Set up a webhook in Azure Repos to call Azure Logic Apps on pull request merge.
Why wrong: Webhooks require custom logic, not a built-in integration.
- B
Add a branch policy that requires a linked work item for pull requests.
This ensures every PR has a work item, and on merge, the work item state can be updated.
- C
In the pull request description, use the #mention syntax to reference the work item.
This links the PR to the work item, enabling automatic updates on merge.
- D
Configure a Service Hooks subscription in Azure DevOps to send pull request merge events to Azure Boards.
Why wrong: Service Hooks send events to external systems, not directly update work items.
- E
Create an Azure Function that listens for pull request merge events and updates work items via the REST API.
Why wrong: This is a custom solution, not a built-in configuration.
AZ-400 Configure processes and communications Practice Question
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.
A team uses Azure Boards to manage work items. They want to automatically update the state of a work item when a related pull request is merged in Azure Repos. Which TWO actions should they configure to enable this integration?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Add a branch policy that requires a linked work item for pull requests.
Option B is correct because a branch policy that requires linked work items for pull requests ensures that every PR is associated with a work item. When the PR is merged, Azure Repos automatically updates the state of the linked work item (e.g., from 'Active' to 'Resolved') based on the default or configured transition rules. This integration is built into Azure DevOps without requiring external services.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse external automation (webhooks, Azure Functions, Logic Apps) with the native, built-in integration that Azure DevOps provides, leading them to select custom solutions instead of the simple branch policy configuration.
Detailed technical explanation
How to think about this question
Under the hood, Azure Repos and Azure Boards share a common identity and work item tracking system. When a branch policy requires linked work items, the PR metadata includes the work item ID. Upon merge, the Azure DevOps platform automatically evaluates the work item state transition based on the project's process template (e.g., Agile, Scrum, CMMI). For instance, in the Agile template, merging a PR linked to a 'User Story' in 'Active' state transitions it to 'Resolved'. This behavior is configurable via the 'Work item transition' settings in the branch policy, allowing teams to define custom state mappings.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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.
