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 developer is on the 'feature/login' branch and wants to integrate the latest changes from 'feature/user-profile' without creating a merge commit. Which Git command should the developer use?
git rebase origin/feature/user-profile
Rebase replays commits on top of the target branch, avoiding a merge commit.
git pull --rebase origin main
Why wrong: This would pull changes from main, not specifically from feature/user-profile.
git merge origin/feature/user-profile
Why wrong: Merge creates a merge commit.
git cherry-pick 9f8e7d6..8a7b6c5
Why wrong: Cherry-pick applies specific commits but is not the standard way to integrate a full branch.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
git rebase origin/feature/user-profile
To integrate changes from another branch without a merge commit, rebase is appropriate. The developer can rebase feature/login onto feature/user-profile (or onto main after merging user-profile). However, the exhibit shows that feature/user-profile is already merged into main, so rebasing feature/login onto main is also valid. The simplest is to rebase feature/login onto main, but that would include all changes. Alternatively, rebasing feature/login onto feature/user-profile directly would also work, but since user-profile is merged into main, rebasing onto main is common. The correct answer is rebase.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
git rebase origin/feature/user-profile
Why this is correct
Rebase replays commits on top of the target branch, avoiding a merge commit.
Related concept

git pull --rebase origin main
Why it's wrong here
This would pull changes from main, not specifically from feature/user-profile.
git merge origin/feature/user-profile
Why it's wrong here
Merge creates a merge commit.
git cherry-pick 9f8e7d6..8a7b6c5
Why it's wrong here
Cherry-pick applies specific commits but is not the standard way to integrate a full branch.
Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
