7. What is the role of the master branch in GitFlow?

• The master branch represents stable code for production.
• The master branch is exclusively for testing code.
• The master branch is used to delete old branches.
• The master branch is a temporary storage for unfinished features.

8. What is the role of the develop branch in GitFlow?

• The develop branch tracks only bug fixes and hotfixes.
• The develop branch is used solely for testing existing features.
• The develop branch holds the final version of the app before release.
• The develop branch serves as the main development branch for integrating new features.

9. How does GitFlow facilitate collaboration among team members?

• GitFlow promotes collaboration by merging all changes directly into the master branch.
• GitFlow discourages collaboration by isolating team members from each other during development.
• GitFlow limits collaboration by requiring all team members to work on the same branch.
• GitFlow facilitates collaboration by allowing team members to work on different features simultaneously using feature branches.

10. What is the benefit of using a distributed version control system like Git in mobile app development?

• A version control system is only used for code backup and does not support collaboration among team members.
• A distributed version control system only allows one developer to work on a project at a time, limiting productivity.
• A distributed version control system like Git allows teams to work on mobile applications efficiently and effectively by tracking changes and facilitating collaboration among developers, regardless of their location.

11. How do you enable version control integration in Android Studio?

• Go to the VCS menu and select Enable Version Control Integration.
• Navigate to Preferences and activate Project Version Settings.
• Click on File and choose Import Version Control Settings.
• Access the Run menu and enable Continuous Version Control.

12. What are some common version control practices for Android app builders?

• Common practices consist of never merging changes and relying entirely on manual backups for versioning.
• Common practices involve solely working on the main branch without creating commits or branches.
• Common practices include only using proprietary tools and avoiding commits to maintain a single version.
• Common version control practices include using traditional VCS tools like Git or SVN, creating commits as checkpoints, using branching and merging practices, and documenting the evolutionary history of the application.

13. What is the purpose of commits in version control?

• Commits control the visibility of code to users, restricting access to sensitive parts.
• Commits manage the hardware resources required by the development environment.
• Commits serve as a way to delete previous versions of the codebase entirely.
• Commits act as checkpoints, marking the app`s specific, stable state before further changes are introduced.

14. How does version control help in debugging and maintenance of mobile apps?

• Version control systems complicate debugging as they do not provide a history of changes made to the application.
• Version control systems only track the latest changes, making it harder to find previous versions of code.
• Version control systems have no impact on debugging or maintenance as they are primarily used for collaboration.
• Version control systems offer the benefit of documenting the evolutionary history of an application, making it easier to debug and maintain by providing a transparent and accessible record of all changes.

15. What is the benefit of using a centralized version control strategy in mobile app development?

• A centralized approach requires all developers to work offline, slowing down the development process.
• A centralized version control strategy facilitates a cohesive approach where changes from various team members can be blended cohesively, avoiding conflicts and maintaining a single source of truth for the current state of the app`s development.
• A centralized version control strategy increases the chances of losing all changes if the server fails or is compromised.
• A centralized strategy promotes individual coding styles, making collaboration harder and less structured.

16. How does GitFlow support efficient collaboration among team members?

• GitFlow isolates team members by preventing them from working on the same codebase.
• GitFlow facilitates collaboration by allowing team members to work on different features simultaneously using feature branches.
• GitFlow limits collaboration by restricting team members to work only on separate branches.
• GitFlow hinders collaboration by requiring team members to merge changes frequently.

17. What is the role of the develop branch in ensuring a stable codebase in GitFlow?

• The develop branch represents the original version of the code without updates.
• The develop branch is used exclusively for bug fixes and maintenance.
• The develop branch integrates new features and maintains a production-ready codebase.
• The develop branch serves as the final release point for the product.

18. How does GitFlow handle bug fixes and hotfixes?

• GitFlow handles bug fixes by discarding the develop branch entirely.
• GitFlow creates hotfix branches from the master branch for bug fixes.
• GitFlow merges all fixes directly to the master and releases them immediately.
• GitFlow only allows bug fixes in the develop branch without hotfixes.

19. What is the significance of the master branch in maintaining the production-ready state of the code?

• The master branch maintains the production-ready state of the code, ensuring it reflects stable software.
• The master branch is meant for tracking user feedback and suggestions for future releases.
• The master branch is primarily for experimental features that are not ready for production.

28. How does GitFlow ensure that the codebase remains stable during the development process?

• GitFlow merges all changes directly to the master branch without testing.
• GitFlow uses release branches for thorough testing before merging into master.
• GitFlow requires all team members to work in a single branch only.
• GitFlow only incorporates code changes after every sprint without reviews.

29. What is the benefit of using a structured branching model like GitFlow in mobile app development?

• It integrates all changes into a single branch, simplifying the development process and eliminating the need for branching strategies.
• The benefit of using a structured branching model like GitFlow is that it promotes clear code isolation, seamless collaboration, and reliable version control, ensuring the stability and quality of the software.
• It allows unlimited access to proprietary code without security measures, which leads to potential breaches.
• It guarantees that the software will always function correctly without the need for testing or quality control.

30. How does GitFlow support flexible and scalable development workflows?

• GitFlow restricts flexibility by enforcing a linear development path that limits team collaboration and adaptation to project changes.
• GitFlow lacks scalability since it does not allow for multiple development branches, making it difficult for teams to manage larger projects efficiently.
• GitFlow discourages collaboration by requiring all developers to work on the same branch simultaneously, leading to increased conflicts and reduced productivity.
