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

Pull requests are created to propose changes from one branch to another. These branches must be different ; otherwise, there would be no changes to propose. Typically, pull requests are made from a feature or topic branch to a main branch (such as main or master ), allowing for code review and integration before the changes are merged.

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

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.

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

The terms Alpha and Beta are often used in software development to describe different stages of feature testing and release.

Alpha Features:

Option A is correct because Alpha features are typically in the early stages of development and are not available to the public. They are usually tested internally or by a limited audience.

Incorrect Options:

Option B is incorrect because Alpha features are often undocumented as they are in the early development phase.

Option C is incorrect because Alpha and Beta features usually do not offer Service Level Agreements (SLAs) due to their experimental nature.

Option D is incorrect because Beta features might offer limited support, but it is not guaranteed, especially compared to fully released features.

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.

A gist on GitHub is essentially a Git repository, albeit a simplified one, designed for sharing snippets of code, notes, or other text content. Gists support version control and can be public or secret.

Gist as a Git Repository:

Option B is correct because each gist is a Git repository, meaning you can clone it, commit changes, and even fork it, just like any other Git repository.

Incorrect Options:

Option A is incorrect because a gist is not an app; it’s a feature of GitHub that provides a simplified repository.

Option C is incorrect because while a gist may contain Markdown documents, it is fundamentally a repository that can hold various file types.

Option D is incorrect because GitHub Pages is a separate service for hosting websites, not related to gists.

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.
