- A
The team should delete the experiment branch because it is not merged.
Why wrong: There is no indication that the branch should be deleted; it may be for future work.
- B
The tag v1.0 was applied to the wrong commit; it should be on the merge commit of the experiment branch.
Why wrong: The experiment branch is not merged into main, so tagging its commit would not represent the release.
- C
The main branch is missing the experiment branch commits; a merge is required before release.
Why wrong: The experiment branch may not be ready for release; merging it could introduce unstable code.
- D
The experiment branch contains experimental work that was not intended for release; the tag v1.0 correctly marks the release on main.
The experiment branch is separate and its commits are not part of main, so they are not included in the release.
AZ-400 Design and implement source control Practice Question
This AZ-400 practice question tests your understanding of design and implement source control. 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.
Refer to the exhibit. A team wants to release version 1.0 from the main branch. They notice that the tag v1.0 is already on the current main commit. However, they also see that the origin/feature/experiment branch has commits that are not merged into main. What is the most likely scenario?
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.
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 experiment branch contains experimental work that was not intended for release; the tag v1.0 correctly marks the release on main.
The tag v1.0 is on the current main commit (9a8b7c6). The feature/experiment branch (1a2b3c4) is a child of the initial commit, but it is not merged into main. The main branch has commits that are ahead of the experiment branch. The team wants to release v1.0 from main; the tag already exists. The presence of the experiment branch not merged suggests that it was not intended for this release. The most likely scenario is that the experiment branch was created from an older commit and is not ready for release, so it was not merged. The release v1.0 is correctly tagged on main.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
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 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.
