GH-900 Exam Dumps - Microsoft GitHub Administrator Questions and Answers

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.

The feature you can use to merge proposed changes in a repository on GitHub is Pull requests. Pull requests are a core feature of GitHub, allowing developers to propose changes to a codebase, review code, discuss the changes, and eventually merge them into the main branch. This collaborative workflow ensures that code is reviewed and vetted before becoming part of the project.

=================

Organization owners on GitHub have control over how GitHub Actions can be used within their organization. They can enforce restrictions to ensure security and compliance with organizational policies.

Allow Actions That Use Self-Hosted Runners:

Option A is correct because organization owners can configure the usage of self-hosted runners, allowing greater control over the environment where actions are run.

Allow Specified Actions:

Option C is correct because organization owners can allow only specific actions to run, adding a layer of security by limiting actions to those that have been vetted.

Allow Actions by Marketplace Verified Creators:

Option D is correct because organization owners can choose to allow actions created by GitHub Marketplace verified creators, ensuring that only trusted actions are used.

Incorrect Options:

Option B is incorrect because GitHub Actions are not designed to be run directly from a Codespace; Codespaces are for development environments.

Option E is a valid choice, but since the prompt asks for only three answers, it is not included in this response.

After 30 minutes of inactivity, a GitHub Codespace will time out. This is designed to conserve resources when the Codespace is not being actively used. The session will be paused, and you'll need to reconnect to resume your work. However, the Codespace is not deleted, and any unsaved changes might not be lost but should be committed or saved to prevent data loss.

=================

GitHub provides several pre-defined repository roles that determine the level of access and permissions a user has within a repository. The roles that are included by default are:

Triage: Allows users to manage issues and pull requests without write access to the code.

Maintain: Provides more extensive access, including managing settings, but without full administrative control.

Write: Grants permission to push changes and manage issues and pull requests.

Roles like "Security" and "Delete" are not standard pre-defined roles, and "View" is generally referred to as "Read" in GitHub's permission structure.

=================

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.

=================

GitHub Projects is a newer, more powerful version of project management within GitHub, offering enhanced features over the classic version.

Multiple Layout Views:

Option A is correct because GitHub Projects supports multiple views, such as board, table, and timeline views, allowing users to visualize their work in different ways according to their needs.

Insights:

Option B is correct because GitHub Projects provides insights and analytics, enabling teams to track progress and make data-driven decisions.

Incorrect Options:

Option C is incorrect because while GitHub Copilot is a tool for code suggestions, it is not directly integrated with GitHub Projects as a feature.

Option D is incorrect because both GitHub Projects and GitHub Projects Classic can be connected to third-party tools, so it is not an exclusive advantage of the newer GitHub Projects.

GitHub Desktop is a standalone application that provides a graphical user interface (GUI) for interacting with GitHub repositories, as opposed to the command-line or web-based interfaces available on github.com.

Graphical User Interface:

Option D is correct because GitHub Desktop offers a GUI, making it easier for users to manage repositories, perform commits, and handle other Git-related tasks without needing to use the command line.

Incorrect Options:

Option A is partially correct in that GitHub Desktop is a standalone application, but the key difference is the GUI.

Option B is incorrect because GitHub Desktop does not specifically enable integration with office suite applications.

Option C is incorrect because GitHub Desktop is available on both Windows and macOS.

Option E is incorrect because GitHub Desktop is not a self-hosted version of GitHub; it is a client application for accessing GitHub repositories.

The primary purpose of creating a security policy in a GitHub repository is to guide users and contributors on how to report security vulnerabilities in a responsible and secure manner. This policy outlines the preferred method of communication, timelines, and any other pertinent information related to handling security issues.

Security Policy:

Option C is correct because a security policy provides guidelines for responsibly disclosing security vulnerabilities. This helps maintainers respond to and address security concerns promptly and securely, thereby protecting the project and its users.

Incorrect Options:

Option A is incorrect because ensuring peer code review is a best practice for code quality, but it is not the primary purpose of a security policy.

Option B is incorrect because push protection for secrets is managed through repository settings, not the security policy.

Option D is incorrect because customizing Dependabot configuration is related to dependency management, not directly to security policies.

A user's GitHub profile typically includes public information such as a personal biography, profile picture, and a list of public repositories. More sensitive information, like email addresses and passwords, is not publicly displayed.

Personal Biography and Profile Picture:

Option A is correct because these are standard elements displayed on a user's public GitHub profile. This information is meant to provide a brief introduction to the user and their interests or skills.

Incorrect Options:

Option B is incorrect because public SSH keys may be associated with a user's account but are not displayed by default on the profile page.

Option C is incorrect because private repositories are not listed on a public profile.

Option D is incorrect because a user's email address and password are private information and not displayed on their public profile.
