Authentic Microsoft Certification Exam GH-900 Questions Answers

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.

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.

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

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.
