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

GitHub Flow is a simple, yet powerful, branching strategy that is widely used in modern software development. It emphasizes collaboration and flexibility.

GitHub Flow:

Option C is correct because GitHub Flow is a lightweight workflow designed for safe experimentation and collaboration. It involves creating branches for new features or fixes, opening pull requests for review, and merging changes back into the main branch after approval.

Incorrect Options:

Option A is incorrect because GitHub Flow uses a single main branch, not multiple primary branches.

Option B is incorrect because GitHub Flow is not specifically designed around releases; it is more focused on continuous development and integration.

Option D is incorrect because GitHub Flow is not strict or linear; it encourages branching and pull requests rather than direct changes on the main branch.

GitHub supports various syntax formats that align with Markdown and HTML conventions. Here's a breakdown of the provided options:

Comment Syntax:

Option C is correct. The syntax is used in Markdown files to insert comments. These comments will not be rendered in the final output, making them useful for adding notes or instructions within the code or documentation.

Incorrect Options:

Option A (* This is a heading) is incorrect because an asterisk (*) denotes an unordered list item, not a heading. A heading in Markdown is typically created with one or more hash symbols (#).

Option B (This is a link) is incorrect because this is plain text and not the syntax for creating a link. The correct syntax would be [This is a link](URL).

Option D (This is bolded text) is incorrect because this is plain text, not the correct Markdown syntax for bold text, which should be **This is bolded text** or __This is bolded text__.

Option E (1. This is an ordered list) is incorrect as it does represent an ordered list item, but it was not the syntax format asked about in the question. The question specifically focuses on matching associated text with syntax, where only the comment option is correct.

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.

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

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.

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

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.

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

From a discussion post on GitHub, a user can Create an issue from the discussion. This feature allows users to turn a discussion into an actionable item by creating an issue directly from the discussion thread. This is particularly useful when a conversation identifies a bug, task, or enhancement that needs to be tracked in the repository.

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

GitHub Copilot for Business offers several features that are tailored to the needs of organizations, providing more control, security, and support compared to the individual version.

Organization-wide Policy Management:

Option B is correct because Copilot for Business allows organizations to manage policies across their entire user base, providing control over how Copilot is used within the organization.

Blocking Suggestions Matching Public Code:

Option C is correct because Copilot for Business includes enhanced security features, such as blocking code suggestions that match public code to prevent inadvertent use of unlicensed code.

Support for Organization or Enterprise GitHub Accounts:

Option E is correct because Copilot for Business supports integration with GitHub Enterprise accounts, offering additional administrative controls and integration capabilities.

Incorrect Options:

Option A (multi-line function suggestions) is a feature available in both individual and business versions, so it does not differentiate the business offering.

Option D (VPN proxy support via self-signed certificates) is not a primary differentiator of Copilot for Business.

Option F (plugs directly into the editor) is true for both individual and business versions, so it is not unique to Copilot for Business.

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.

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

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 following two-factor authentication (2FA) methods can be used to secure a GitHub account:

A. Authenticator app: You can use an authenticator app (like Google Authenticator or Authy) to generate time-based one-time passwords (TOTP) for logging in.

C. GitHub mobile: The GitHub mobile app can also be used to receive 2FA codes, adding convenience for users who prefer to manage everything from their mobile devices.

D. Security keys: Physical security keys (such as YubiKeys) can be used as a strong form of 2FA, requiring physical access to the key to authenticate.

Security questions and Single sign-on (SSO) are not considered 2FA methods in the context of GitHub account security.
