GitHub Actions Jobs Steps Runners Quiz

1. What does 'continue-on-error: true' do in a step?

Allows the job to continue even if the step fails

Retries the step automatically if it fails

Suppresses error messages from the step

Skips the step if a previous step failed

2. How do you access a secret in a GitHub Actions step?

Using ${{ secrets.SECRET_NAME }}

Using ${{ env.SECRET_NAME }}

Using ${{ vars.SECRET_NAME }}

Using ${{ github.secrets.SECRET_NAME }}

3. In GitHub Actions, what does 'env' at the workflow level do?

Defines environment variables available to all jobs

Specifies the operating system for runners

Sets permissions for accessing repository secrets

Configures concurrency limits for the workflow

4. What is the default timeout for a job in GitHub Actions?

360 minutes

60 minutes

120 minutes

30 minutes

5. Which of these is a valid GitHub-hosted runner operating system?

Ubuntu, Windows, and macOS

CentOS, Debian, and Alpine

RedHat, SUSE, and Oracle Linux

FreeBSD, OpenBSD, and NetBSD

6. What does the 'if' conditional in a step allow you to do?

Execute the step only if a specified condition is true

Define alternative actions if the step fails

Set environment-specific configurations

Control the number of parallel job executions

7. How do you reference the output of a previous step in a later step?

Using ${{ steps.step-id.outputs.output-name }}

Using ${{ env.STEP_OUTPUT }}

Using ${{ secrets.PREVIOUS_STEP }}

Using ${{ jobs.previous-job.outputs }}

8. In a matrix strategy, what does 'fail-fast: false' accomplish?

Allows all matrix combinations to run even if one fails

Cancels all remaining jobs if one fails

Speeds up job execution by running jobs in parallel

Prevents matrix jobs from running on self-hosted runners

9. What is the purpose of the 'strategy' keyword in a job?

To create a matrix of job instances with different configurations

To define the order of step execution

To set timeout limits for the job

To specify which runner should execute the job

10. Which runner label indicates a Windows operating system?

Windows-latest

Linux-latest

Macos-latest

Ubuntu-latest

11. What is the primary purpose of a GitHub Actions job?

A set of steps that execute sequentially on a runner

A single shell command executed on a workflow

A template for creating reusable workflows

A notification sent after workflow completion

12. How do you pass inputs to an action in a step?

Using the 'with' keyword followed by key-value pairs

Using environment variables defined at the job level

Using command-line arguments after the action name

Using the 'inputs' section in the action metadata

13. What is the difference between 'run' and 'uses' in a step?

'run' executes shell commands; 'uses' executes an action

'run' is for scheduled workflows; 'uses' is for event-triggered

'run' requires a self-hosted runner; 'uses' requires GitHub-hosted

'run' is deprecated; 'uses' is the modern approach

14. In a step, what is the 'uses' keyword used for?

To reference an action from the GitHub Marketplace or a local path

To define the shell interpreter for shell commands

To set the working directory for the step

To specify timeout duration for the step

15. What does the 'needs' keyword do in a GitHub Actions job?

Specifies job dependencies and execution order

Defines environment variables for the job

Sets resource limits for the runner

Declares required secrets for the job

16. How do you specify the runner for a job in a workflow?

Using the 'runs-on' keyword

Using the 'runner-type' keyword

Using the 'machine' keyword

Using the 'environment' keyword

17. Which keyword defines a job in a GitHub Actions workflow file?

Jobs

Tasks

Steps

Runners

18. What is the key difference between GitHub-hosted and self-hosted runners?

GitHub-hosted are managed by GitHub; self-hosted are maintained by the user

Self-hosted runners are always faster than GitHub-hosted

GitHub-hosted runners support only JavaScript actions

Self-hosted runners cannot execute public workflows

19. In GitHub Actions, what does a step represent?

An individual task or command executed within a job

A separate workflow file in the repository

A trigger condition for the entire workflow

A security permission assigned to a runner

20. Which of the following best describes a runner in GitHub Actions?

A machine that executes the steps defined in a job

A pre-built action available in the GitHub Marketplace

A configuration file for defining workflow triggers

A scheduled task that runs on a fixed interval
