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.
Which THREE of the following are best practices when using Git for a collaborative project? (Choose three.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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
✓
Use feature branches for new work.
A is correct because feature branches isolate new work from the stable main branch, enabling parallel development without disrupting the shared codebase. This practice aligns with Git's branching model and supports code review and continuous integration workflows.
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
Cisco often tests the misconception that committing directly to main is acceptable for small changes, but the exam emphasizes that all changes should go through feature branches to maintain a clean, reviewable history.
Detailed technical explanation
How to think about this question
Feature branches work by creating a lightweight pointer to a commit, allowing isolated commits without affecting the main branch until merged. Regular rebasing or merging incorporates upstream changes, reducing the likelihood of large, conflict-prone merges later. In a real-world CI/CD pipeline, feature branches are often automatically tested before merging, and descriptive commit messages (e.g., referencing issue trackers) aid in debugging and release notes.
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.
