GitHub-Foundations GitHub Foundations Exam Practice Test

Answer : A

In GitHub, an organization member is a user who has been added to an organization and is subject to the organization's base permissions and policies. An outside collaborator is a user who is not a member of the organization but has been granted access to one or more repositories within the organization.

Here's the difference between an organization member and an outside collaborator:

Organization Members:

Members are subject to the organization's base permissions, which apply across all repositories within the organization. These permissions might include read, write, or admin access, depending on what has been set as the default.

Members consume paid licenses if the organization is on a paid plan.

Members are required to have two-factor authentication (2FA) if the organization enforces it.

Outside Collaborators:

Outside collaborators do not have organization-wide permissions. They only have access to specific repositories to which they have been granted permission. This means organization base permissions do not apply to them (making option A correct).

Outside collaborators do not consume paid licenses. They are only counted toward the license if they are made organization members.

Outside collaborators can be granted any level of permission, including the admin role on specific repositories.

Two-factor authentication (2FA) can be enforced for outside collaborators at the repository level, depending on the organization's security settings.

Given this information, option A is the correct answer: 'Organization base permissions do not apply to outside collaborators.'

Answer : D

A GitHub repository serves as a collaborative space where developers can share and manage code files, track changes, and store revision history. It is much more than just a folder or simple tool; it is a comprehensive version control system that allows teams to collaborate effectively on codebases. Repositories enable developers to work together, manage contributions, review code, and maintain a complete history of every change made to the project.

Answer : C

In GitHub Discussions, several default categories are provided to help organize conversations within a project. One of the default categories is Show and tell. This category is designed for users to showcase their work, share progress, or discuss achievements with the community. The other options listed (Bug report, Daily check-in, Security concern) are not default categories but could be custom categories created by the repository maintainers.

Answer : C

A distributed version control system (DVCS) like Git is best described as a system that ensures each developer has their own local copy of the entire code repository, including the complete project history and metadata. This decentralized approach allows developers to work independently, with full access to the project's history and files, and later synchronize their changes with others. Unlike centralized systems, DVCS does not rely on a single central server, which provides greater flexibility and robustness in collaboration.

Answer : A, C, D

When using GitHub Codespaces, you can customize several aspects of the development environment:

Shell: You can choose the default shell to be used in the Codespace, such as Bash, Zsh, or PowerShell.

Name: Users can customize the name of their Codespace for easier identification.

Default editor: You can choose which editor to use within the Codespace, such as Visual Studio Code or others that may be supported.

Branch protections and the operating system are not customizable for an individual Codespace within GitHub, making the options Shell, Name, and Default editor the correct answers.

Answer : A

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.

Answer : A

The terms Alpha and Beta are often used in software development to describe different stages of feature testing and release.

Alpha Features:

Option A is correct because Alpha features are typically in the early stages of development and are not available to the public. They are usually tested internally or by a limited audience.

Incorrect Options:

Option B is incorrect because Alpha features are often undocumented as they are in the early development phase.

Option C is incorrect because Alpha and Beta features usually do not offer Service Level Agreements (SLAs) due to their experimental nature.

Option D is incorrect because Beta features might offer limited support, but it is not guaranteed, especially compared to fully released features.
