Microsoft GitHub Foundations 認定 GH-900 試験問題 (Q70-Q75):
質問 # 70
What is the primary purpose of creating a new branch in the GitHub flow?
正解：D
解説：
In GitHub Flow, creating a new branch is a key step in the development process that allows for isolated development of new features or fixes without affecting the main codebase.
Experimenting with New Features or Fixes:
Option C is correct. The primary purpose of creating a new branch in the GitHub flow is to provide a safe space to experiment with new features or fixes. This allows developers to work on changes independently and only merge them into the main branch after they have been reviewed and approved.
Incorrect Options:
Option A (To create a backup of the main branch) is incorrect because branches are not typically used for backups; they are for active development.
Option B (To capture information about an issue) is incorrect because issues are tracked separately; branches are for code changes.
Option D (To incorporate changes from a review) is incorrect because incorporating changes is done during the pull request process, not when creating a branch.

質問 # 71
What are the defining features of Git?
正解：C
解説：
Git is a widely-used version control system that has several defining features:
Distributed Version Control:
Git is a distributed version control system, meaning that every developer has a full copy of the entire repository, including its history, on their local machine. This enables greater flexibility, as work can be done offline and each user has access to the full project history.
Open Source Software:
Git is open-source, meaning its source code is freely available for use, modification, and distribution. This fosters a large community of users and contributors who continuously improve the software.
Efficiency with Large Projects:
Git is designed to handle projects of any size with speed and efficiency. It can manage large codebases and many contributors without significant performance degradation, making it suitable for everything from small personal projects to large, complex software systems.
Incorrect Options:
Option B is incorrect because Git is not a sequential version control system, nor is it inherently tied to cloud-based services. GitHub, GitLab, and other platforms offer cloud hosting for Git repositories, but Git itself is a version control tool.
Option C is incorrect because Git is not limited to small projects; it is designed to scale efficiently, and the other features mentioned are only partial descriptions of Git's capabilities.
Option D is incorrect because Git is not a centralized version control system; it is distributed. Additionally, Git is open-source, not proprietary, and is used for projects of all sizes.

質問 # 72
What are the two main reasons why one might fork a repository?
(Each answer presents a complete solution. Choose two.)
正解：A、D
解説：
Forking a repository on GitHub is a common practice, especially when contributing to open-source projects or when you want to build on existing work. Here are the two main reasons for forking a repository:
B . To propose changes to the base repository:
One of the primary reasons for forking a repository is to make changes or improvements that you can later propose to the original repository (often called the "upstream" repository). This is typically done through a pull request. By forking the repository, you get your own copy of the project where you can freely experiment, make changes, and then propose those changes back to the original project.
C . To create a new repository based on an existing one:
Forking is also used to create a new repository that is a copy of an existing one. This allows you to work on the project independently of the original repository, effectively creating a new direction for the project or using it as a starting point for a different purpose. This is particularly useful for customization, experimentation, or when you want to build something different while still leveraging the existing codebase.
Explanation of Other Options:
A . To create an issue or open a discussion:
This is incorrect because creating an issue or opening a discussion can be done directly on the original repository without needing to fork it. Forking is unnecessary for these actions.
D . To create a new branch to develop a new feature:
While creating a new branch is related to development, it does not require a fork. Branches are typically created within the same repository to work on new features. Forking is used when you need an entirely separate copy of the repository.
Given this information, the correct answers are B and C.

質問 # 73
Pull requests can only be created between two branches that are:
正解：A
解説：
Pull requests are created to propose changes from one branch to another. These branches must be different; otherwise, there would be no changes to propose. Typically, pull requests are made from a feature or topic branch to a main branch (such as main or master), allowing for code review and integration before the changes are merged.
質問 # 74
Workflows can reference actions in:
(Each correct answer presents a complete solution. Choose three.)
正解：B、C、D
解説：
In GitHub Actions workflows, actions can be referenced from various sources depending on the needs of the workflow.
Any Public Repository:
Option A is correct. Actions can be referenced from any public GitHub repository, allowing the reuse of shared actions across multiple projects.
The Same Repository as Your Workflow File:
Option B is correct. Actions stored in the same repository as the workflow file can be referenced directly, which is common for custom actions specific to that project.
A Published Docker Container Image on Docker Hub:
Option E is correct. Workflows can reference actions that are provided as Docker container images hosted on Docker Hub, allowing integration of complex tools and environments.
Incorrect Options:
Option C (GitHub Packages) is incorrect as it is more commonly used for storing and managing dependencies, not actions.
Option D (An enterprise marketplace) is incorrect because GitHub Actions are not directly referenced from an enterprise marketplace but rather from public repositories or Docker images.
