- A
git rebase main
Why wrong: Missing fetch; need to fetch latest main first. But the command itself is correct if main is up-to-date, but typically you'd fetch first.
- B
git merge main
Why wrong: Merge creates a merge commit, which is not desired here.
- C
git pull --rebase origin main
This fetches and rebases the current branch onto main, incorporating changes without a merge commit.
- D
git checkout main && git pull && git checkout feature-login && git merge main
Why wrong: This creates a merge commit.

200-901 Software Development and Design Practice Question
This 200-901 practice question tests your understanding of software development and design. 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.
A developer is using Git for version control. After creating a new feature branch 'feature-login' from 'main', they make several commits. Meanwhile, another developer has merged changes into 'main'. The developer wants to incorporate the latest main changes into 'feature-login' without creating a merge commit. Which Git command should they use?
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
✓
git pull --rebase origin main
Option C is correct because `git pull --rebase origin main` fetches the latest changes from the remote `main` branch and then rebases the current `feature-login` branch onto those changes. This incorporates the new commits from `main` without creating a merge commit, resulting in a linear history. The `--rebase` flag ensures that the developer's commits are replayed on top of the updated `main`, avoiding the extra merge commit that `git merge` would create.
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.
- ✗
git rebase main
Why it's wrong here
Missing fetch; need to fetch latest main first. But the command itself is correct if main is up-to-date, but typically you'd fetch first.
- ✗
git merge main
Why it's wrong here
Merge creates a merge commit, which is not desired here.
- ✓
git pull --rebase origin main
Why this is correct
This fetches and rebases the current branch onto main, incorporating changes without a merge commit.

Why it's wrong here
This creates a merge commit.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between `git merge` and `git rebase` in the context of avoiding merge commits, and the trap here is that candidates may choose `git rebase main` (Option A) without realizing it does not fetch remote changes, or they may choose `git merge main` (Option B) thinking it can be done without a merge commit, which is incorrect.

Command / output trap
Missing fetch; need to fetch latest main first. But the command itself is correct if main is up-to-date, but typically you'd fetch first.
Detailed technical explanation
How to think about this question
Under the hood, `git pull --rebase` performs a `git fetch` followed by `git rebase FETCH_HEAD`. This replays the local commits from `feature-login` onto the tip of the remote `main`, effectively rewriting the branch history. In a real-world scenario, this is commonly used in feature branches to keep a clean, linear history before merging into `main`, especially in workflows that enforce a linear commit history (e.g., using `git rebase` before a fast-forward merge). A subtle behavior is that rebasing rewrites commit hashes, which can cause issues if the branch is shared with other developers; in such cases, `git merge` might be preferred despite the merge commit.
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 practitioner preparing for the 200-901 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
