AZ-400 Configure processes and communications Practice Question
This AZ-400 practice question tests your understanding of configure processes and communications. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 uses GitHub and wants to automatically assign pull request reviewers based on the files changed. Which three steps should you take?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure 'Code owner review requirement' in branch protection.
Option A is correct because configuring 'Code owner review requirement' in branch protection enforces that pull requests affecting files with defined code owners must be approved by those owners before merging. This ensures that changes to specific file patterns automatically require review from the designated teams or individuals, aligning with the goal of automatic assignment based on files changed.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Enable 'Protected branches' for the main branch.
Why it's wrong here
Protected branches is a concept, not a specific setting for auto-assignment.
✗
Configure team synchronization for the organization.
Why it's wrong here
Team sync syncs with IdP, does not assign reviewers.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse 'Require pull request reviews before merging' (which only requires any reviewer approval) with 'Code owner review requirement' (which specifically requires approval from the code owner defined in CODEOWNERS), leading them to think option C alone is sufficient without the CODEOWNERS file and the code owner enforcement.
Detailed technical explanation
How to think about this question
The CODEOWNERS file uses glob patterns to match file paths and assigns owners (users or teams) who are automatically requested for review when a pull request modifies those files. Under the hood, GitHub evaluates the diff against the CODEOWNERS patterns in the repository's default branch, and if the 'Require pull request reviews before merging' and 'Code owner review requirement' are both enabled, the pull request cannot be merged until a code owner approves, even if other reviewers have approved.
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.
