Microsoft GH-900 Practice Exam Questions & Answers

Explanation

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.

Explanation

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.

Explanation

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.'

Explanation GitHub Enterprise Server is a self-hosted solution that runs on your own infrastructure, giving your organization full control over deployment, customization, and security. In contrast, GitHub Enterprise Cloud is a managed service hosted by GitHub where they handle infrastructure maintenance and updates. With GHES, you manage everything yourself including backups, upgrades, and security patches. This makes it ideal for organizations with strict compliance requirements or those who need to keep code on premises.

Explanation

The GitHub Command Palette provides quick keyboard-based access to navigation, commands, repositories, issues, pull requests, projects, and other GitHub areas. On GitHub.com, Windows and Linux users can open the Command Palette by pressing Ctrl+K. This shortcut helps users move faster through GitHub without relying only on menus or page navigation. Ctrl+S is commonly associated with saving in many applications, not opening the GitHub Command Palette. Shift+Enter is generally used for line breaks or text-entry behavior in many interfaces. Alt+P is not the standard GitHub.com shortcut for this feature. Knowing Command Palette shortcuts is useful for the GitHub Foundations exam because it tests productivity features available directly in the GitHub web interface.

Explanation

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.
