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 development team wants to ensure that all code changes are reviewed by at least two senior developers before merging into the main branch. They use Azure Repos. What should they configure?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "least"
Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure a branch policy requiring a minimum number of reviewers.
Option C is correct because Azure Repos branch policies allow you to enforce a minimum number of reviewers on pull requests. By setting the 'Minimum number of reviewers' policy to 2, the team ensures that at least two senior developers must approve any code change before it can be merged into the main branch. This directly meets the requirement without involving build validation, release pipelines, or external function calls.
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.
✗
Enable the build validation policy on the branch.
Why it's wrong here
Build validation ensures code compiles but does not enforce reviewer count.
✗
Set up a release pipeline with gated deployments.
Why it's wrong here
Release pipelines control deployments, not code review requirements.
✓
Configure a branch policy requiring a minimum number of reviewers.
Why this is correct
Branch policies can enforce a minimum number of reviewers for pull requests.
Clue confirmation
The clue word "least" in the question point toward this answer.

✗
Add a status check policy using Azure Functions.
Why it's wrong here
Status checks can enforce external conditions but not specifically reviewer count.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse build validation policies (which ensure code compiles) with reviewer policies (which ensure human oversight), leading them to select option A instead of C.
Detailed technical explanation
How to think about this question
Azure Repos branch policies are enforced at the server side via the Git ref update hook, preventing pushes that violate the policy. The 'Minimum number of reviewers' policy works by requiring a specific count of approved votes on the pull request; if the count is not met, the merge button is disabled and the PR cannot be completed. This policy can be combined with other policies like 'Check for linked work items' or 'Comment resolution' to create a comprehensive quality gate.
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 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.
