GH-900 Exam Preparation Material | GitHub Foundations

Prepare for the GH-900 with reliable study materials, practice questions, and key exam insights.

Prepare for the GH-900 GitHub Foundations exam with CertQueen's independently developed study resources. Review important concepts, practice scenario-based questions, and use clear explanations to identify areas that require further study.

Question#1

What best describes Markdown?

A. Markup language
B. Programming language
C. Scripting language
D. Version control system
E. Containerization solution

Explanation:
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.

Question#2

Which of the following is a restriction for Enterprise Managed Users (EMUs)?

A. Organization base permissions cannot be applied.
B. Users cannot create public repositories.
C. Each GitHub team must be linked to an identity provider group.
D. Custom repository roles are not available.

Question#3

Which of the following best describes cloning a repository?

A. It creates a copy of the repository on GitHub.com.
B. It retrieves code updates from the remote repository.
C. It creates a copy of the repository on your local machine.
D. It imports your source code into a new repository.

Explanation:
Cloning a repository in GitHub refers to creating a copy of the repository on your local machine. This allows you to work on the project offline, make changes, and later push those changes back to the remote repository. It does not involve creating a copy on GitHub.com (which would be forking), retrieving updates (which would be pulling), or importing source code into a new repository (which is done differently).

Question#4

A centralized version control system is a system that:

A. requires developers to manually track and manage different versions of their files using naming conventions and manual backups.
B. stores project files on a cloud-based server and allows multiple developers to collaborate on the same files simultaneously.
C. relies on a central server to store the entire project history and allows developers to check out files for editing.
D. ensures each developer has their own local copy of the central code repository, including the complete project history and metadata.

Explanation:
A centralized version control system stores the main project history in one central location, usually a server. Developers connect to that server to check out files, make changes, and submit updates. This differs from Git, which is distributed and allows every developer to have a full local copy of the repository history. In a centralized model, collaboration depends heavily on the availability of the central server. If the server is unavailable, developers may be limited in what they can do. GitHub Foundations emphasizes this distinction because GitHub is built around Git, a distributed version control system.
Option C correctly describes centralized version control because the central server holds the authoritative project history.

Question#5

Workflows can reference actions in: (Each correct answer presents a complete solution. Choose three.)

A. Any public repository.
B. The same repository as your workflow file.
C. GitHub Packages.
D. An enterprise marketplace.
E. A published Docker container image on Docker Hub.

Explanation:
In GitHub Actions workflows, actions can be referenced from various sources depending on the needs of the workflow.
Any Public Repository:
Option A is correct. Actions can be referenced from any public GitHub repository, allowing the reuse of shared actions across multiple projects.
The Same Repository as Your Workflow File:
Option B is correct. Actions stored in the same repository as the workflow file can be referenced directly, which is common for custom actions specific to that project.
A Published Docker Container Image on Docker Hub:
Option E is correct. Workflows can reference actions that are provided as Docker container images hosted on Docker Hub, allowing integration of complex tools and environments.
Incorrect Options:
Option C (GitHub Packages) is incorrect as it is more commonly used for storing and managing dependencies, not actions.
Option D (An enterprise marketplace) is incorrect because GitHub Actions are not directly referenced from an enterprise marketplace but rather from public repositories or Docker images.
