AZ-400 Configure processes and communications Practice Question
This AZ-400 practice question tests your understanding of configure processes and communications. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 and wants to ensure that work items moved to the 'Done' state require a completed code review. What should they configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add a work item rule in the process template to require a code review for the 'Done' transition.
Option A is correct because Azure Boards allows you to define work item rules within the process template that enforce specific conditions on state transitions. By adding a rule to the 'Done' transition that requires a completed code review (e.g., via a custom field or check), you ensure work items cannot be moved to 'Done' without meeting that prerequisite. This is done through the inherited process customization in Azure DevOps, where you can add rules to the work item type's state transition.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Add a work item rule in the process template to require a code review for the 'Done' transition.
Why this is correct
Work item rules enforce conditions on state transitions.

Read the scenario before looking for a memorised answer.
✗
Modify the work item type definition to add a custom field for code review status.
Why it's wrong here
Adding a field does not enforce the transition condition.
✗
Use a tag to mark work items as code-reviewed before moving to 'Done'.
Why it's wrong here
Tags are not enforceable rules.
✗
Configure branch policies in Azure Repos to require pull request approvals.
Why it's wrong here
Branch policies apply to code, not work item states.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing Azure Repos branch policies (which enforce code review on pull requests) with Azure Boards work item rules (which enforce conditions on work item state transitions), leading candidates to select Option D instead of A.
Detailed technical explanation
How to think about this question
Work item rules in Azure Boards are defined via the XML process template or the inherited process model, using conditions like 'When the state changes to Done' and actions like 'Require a field to have a value' or 'Check that a specific field is set'. Under the hood, these rules are evaluated server-side during work item saves, preventing invalid transitions. In a real-world scenario, you might combine this with a custom 'Code Review Completed' field (Yes/No) and a rule that blocks the transition if that field is not set to 'Yes'.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
