GH-900 Practice Questions

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.

GitHub automatically subscribes users to conversations when their direct involvement indicates they may need future notifications. Being at-mentioned in a thread subscribes the mentioned user because GitHub treats the mention as a direct request for attention. Opening a pull request also subscribes the author because they own the proposed change and need updates about reviews, comments, checks, and merge activity. Commenting on an issue or pull request subscribes the commenter because they have participated in the conversation and may need follow-up notifications. Deleting a branch does not represent participation in a specific conversation, and changing repository visibility is an administrative repository action rather than a conversation-level activity. Automatic subscriptions help users stay informed about discussions relevant to them.

On GitHub, certain actions automatically subscribe you to conversations so that you receive notifications about further activity in that thread.

Opening a Pull Request or Issue:

Option C is correct because when you open a pull request or issue, you are automatically subscribed to the conversation and will receive notifications for any updates.

Commenting on a Thread:

Option D is correct because commenting on an issue or pull request automatically subscribes you to that thread, ensuring you are notified of further comments or changes.

Being Assigned to an Issue or Pull Request:

Option E is correct because when you are assigned to an issue or pull request, you are automatically subscribed to notifications related to it.

Incorrect Options:

Option A is incorrect because pushing a commit to the default branch does not automatically subscribe you to conversations.

Option B is incorrect because being added as a repo admin does not automatically subscribe you to specific conversations unless you engage with them.

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.

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

In GitHub, issues and pull requests (PRs) are essential tools for managing work and collaboration in a project. Assigning individuals to these issues or PRs is a way to indicate responsibility for addressing the issue or completing the PR.

Anyone with write permissions to the repository:

Users who have write permissions to a repository can be assigned to issues and pull requests. Write permissions allow users to push changes to the repository, create branches, and modify issues and pull requests. Assigning them to an issue or PR ensures they are recognized as responsible for the task.

Anyone who has commented on the Issue or pull request:

GitHub allows you to assign issues or pull requests to users who have already engaged with the discussion by commenting on it. This feature is particularly useful for quickly assigning tasks to those who are already involved in the conversation.

Incorrect Options:

Option A is incorrect because having an enterprise GitHub account alone does not necessarily grant the ability to be assigned to issues or PRs. Permission to assign is based on repository-specific roles and permissions.

Option C is incorrect because not all personal GitHub accounts can be assigned to issues or PRs. The user needs either write permissions to the repository or must have commented on the issue or PR.
