GH-900 Questions and Answers

In GitHub, when viewing the list of projects for an organization, a user can identify a GitHub Projects template by selecting the Templates tab. This tab specifically lists available templates that can be used to create new projects based on predefined structures and workflows.

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

GitHub Mobile provides a streamlined experience for managing your GitHub notifications and participating in discussions, but it does not offer full functionality compared to the desktop or web interface.

Managing Notifications:

Option E is correct because GitHub Mobile allows users to manage notifications, keeping them up to date with their repositories, issues, pull requests, and other activities on GitHub.

Incorrect Options:

Option A is incorrect because GitHub Mobile cannot be used as a self-hosted runner.

Option B is incorrect because managing enterprise and organization settings is not supported in GitHub Mobile.

Option C is incorrect because GitHub Mobile does not offer a chat or voice calling feature.

Option D is incorrect because forking and cloning repositories are not actions available in GitHub Mobile.

Two recommended ways to improve the discoverability of a repository on GitHub are:

B. Create a README file describing the repository: A well-written README file provides essential information about the project, such as what it does, how to use it, and how to contribute. This is often the first thing potential users or contributors will see, making it critical for discoverability.

D. Add topics to classify the repository: Adding topics to your repository helps classify it under specific categories, making it easier for others to find it through GitHub’s search and exploration features. Topics act like tags, helping to connect your project with users interested in similar subjects.

Registering a repository with GitHub search and adding labels are not applicable actions for improving discoverability in the broader sense.

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

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.

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

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.

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

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.

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

GitHub Projects supports various layouts to help teams organize and visualize their work. The available layouts include:

B. Kanban: This is a visual task management tool where tasks are represented as cards and moved across columns that represent different stages of work.

C. Board: This layout is similar to Kanban but can be more flexible, allowing users to set up boards in various ways to suit their workflow needs.

D. Table: The Table layout allows you to view your tasks in a spreadsheet-like format, making it easy to manage and edit large amounts of data at once.

Roadmap and Backlog are not standard layouts provided by GitHub Projects. While these terms might be relevant in other project management contexts, GitHub Projects specifically offers Kanban, Board, and Table layouts.

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

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."

The CODEOWNERS file in a GitHub repository is used to define individuals or teams that are responsible for specific parts of the codebase. When changes are made to files or directories that match the patterns specified in the CODEOWNERS file, GitHub automatically requests reviews from the listed code owners.

Setting Reviewers Automatically:

Option D is correct because the primary purpose of a CODEOWNERS file is to automatically set reviewers for pull requests that affect the specified files or directories. This ensures that the appropriate team members are notified and review the changes before they are merged.

Incorrect Options:

Option A is incorrect because the CODEOWNERS file does not restrict who can edit specific files; it only influences who is required to review changes.

Option B is partially related but not fully accurate because while CODEOWNERS does require certain reviews, it does not mandate peer review for all code changes.

Option C is incorrect because the CODEOWNERS file does not define access permissions for the repository; it deals with code review processes.

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.

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

The GitHub Marketplace is the place where users can discover, browse, and install various tools and integrations that extend the functionality of GitHub. These tools can include CI/CD services, security checks, and other development utilities that enhance workflow automation and project management.

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

Markdown is a lightweight markup language with plain-text formatting syntax. It is designed to be easy to write and read in its raw form, and it can be converted into HTML and other formats. Markdown is commonly used for formatting readme files, writing messages in online discussion forums, and creating rich text documents.

Markup Language:

Option A is correct because Markdown is indeed a markup language. It is not a programming language, scripting language, version control system, or containerization solution.

Incorrect Options:

Option B is incorrect because Markdown is not a programming language; it does not involve control structures or variables.

Option C is incorrect because Markdown is not used for scripting or automation.

Option D is incorrect because Markdown does not manage version control.

Option E is incorrect because Markdown is not related to containerization technologies like Docker.

The Codespaces lifecycle on GitHub includes several key steps:

Create: This is the step where a new Codespace is initiated.

Rebuild: A Codespace can be rebuilt to ensure that the environment is up-to-date with the latest code or configurations.

Delete: Once a Codespace is no longer needed, it can be deleted to free up resources.

Committing, cloning, or installing are typical Git operations but are not considered part of the specific lifecycle steps for a GitHub Codespace.

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

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 provides a powerful search syntax to filter and find specific issues across repositories in an organization.

Search Query Syntax:

Option A is correct because the query org:Avocado is:issue label:guacamole "404 error" is the best way to search for all issues within the "Avocado" organization that contain the text "404 error" and are labeled with "guacamole". This query is precise and leverages GitHub’s advanced search capabilities.

Incorrect Options:

Option B is incorrect because it requires manual filtering in a specific repository rather than searching across the entire organization.

Option C is incorrect because selecting "Issues" in the filter by section is redundant when using the query is:issue.

Option D is incorrect because accessing organization settings to look for repository labels is not relevant to searching for issues.

The "Pinned Repositories" section of a GitHub user profile displays repositories that were personally selected to be highlighted by the user. Users can choose which repositories they want to feature prominently on their profile, regardless of recent activity, star count, or organizational ownership.

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

GitHub Projects is a flexible and powerful tool for project management that allows users to manage their work with ease. One of the key characteristics of GitHub Projects is the ability to create and customize multiple views. This feature enables teams to tailor the project management experience to their specific workflow needs, offering various ways to visualize tasks, issues, and work items.

Custom Views: You can set up different views like Kanban boards, tables, or timelines, and apply filters to show only what is relevant for a particular aspect of the project. This customization allows teams to organize their work in a way that best suits their processes, making it a highly adaptable project management tool.

Other options, such as visualizing commit history (which would fall under the 'Insights' feature), importing Gantt charts (which GitHub Projects does not natively support), or enforcing required fields (which might relate to form-based tools but not to GitHub Projects specifically), do not align with the key characteristics of GitHub Projects.
