AZ-400 Design and implement source control Practice Question

This AZ-400 practice question tests your understanding of design and implement source control. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.

Network Topology

Refer to the exhibit. A developer attempts to push a commit directly to the main branch of FabrikamWeb repository but receives a push rejection. What is the most likely reason?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

Network Topology

A
The developer tried to push to the wrong remote URL.
Why wrong: The exhibit does not indicate any URL mismatch; the error is likely due to policy.
B
The FabrikamWeb repository has a minimum number of reviewers policy set to 1, which blocks direct pushes.
Why wrong: The MinimumNumberOfReviewers policy is shown as enabled and blocking, but it applies to pull requests, not direct pushes. However, it could still block pushes if the policy is configured to require reviews on push, but typically such policies are for PRs.
C
The developer does not have permission to push to the main branch due to branch policies requiring pull requests.
Branch policies on main typically enforce that all changes must go through pull requests and be reviewed.
D
The main branch does not exist in the FabrikamWeb repository.
Why wrong: The exhibit shows the repository has a default branch 'develop', but main may still exist. The error is not about missing branch.

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

✓

The developer does not have permission to push to the main branch due to branch policies requiring pull requests.

The repository FabrikamWeb has a default branch 'develop', and the merge strategy policy may require that all changes be made via pull requests. Also, the absence of a policy on main branch suggests that main is protected by branch policies that are not listed because the query was for the develop branch. However, the question is about pushing to main. Given the exhibit shows policies for the repository, but not specifically for main branch, the most likely cause is that the branch policies are set on the default branch (develop) and maybe also on main, but the push rejection could be due to a branch policy requiring pull requests. However, the correct answer is that the main branch is protected by a branch policy that requires pull requests, which is a common setting.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

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.
Use explanations to understand the rule behind the answer.

TExam Day Tips

Underline the problem statement mentally.
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.
