GitHub GITHUB-ACTIONS Online Practice Questions and Exam Preparation

GitHub GITHUB-ACTIONS Online Questions & Answers

• Question 41:

  Which of the following scenarios would require the use of self-hosted runners instead of GitHub-hosted runners?

  A. running more than the three concurrent workflows supported by GitHub-hosted runners
  B. exceeding 50,000 monthly minutes of build time
  C. using Docker containers as part of the workflow
  D. using specialized hardware configurations required for workflows
  E. performing builds on macOS
  A. running more than the three concurrent workflows supported by GitHub-hosted runners
  D. using specialized hardware configurations required for workflows

  ---

  GitHub-hosted runners have a limit on the number of concurrent workflows (typically 20 for free-tier accounts and 5 for enterprise). If your organization needs to run more workflows simultaneously, you would need to use self-hosted runners to increase the available concurrency.

  Self-hosted runners allow you to configure specialized hardware or software setups that are necessary for certain workflows. GitHub-hosted runners may not have access to custom hardware configurations like GPUs or other specialized resources, so self-hosted runners are required in such cases.

• Question 42:

  You need to make a script to retrieve workflow run logs via the API. Which is the correct API to download a workflow run log?

  A. POST /repos/:owner/:repo/actions/runs/:run_id
  B. GET /repos/:owner/:repo/actions/artifacts/logs
  C. GET /repos/:owner/:repo/actions/runs/:run_id/logs
  D. POST /repos/:owner/:repo/actions/runs/:run_id/logs
  C. GET /repos/:owner/:repo/actions/runs/:run_id/logs

  ---

  The GET /repos/:owner/:repo/actions/runs/:run_id/logs API endpoint is used to retrieve the logs of a specific workflow run identified by run_id. This is the correct method for downloading logs from a workflow run.

• Question 43:

  A development team has been using a Powershell script to compile and package their solution using existing tools on a Linux VM, which has been configured as a self-hosted runner. They would like to use the script as- is in an automated workflow. Which of the following should they do to invoke their script within a workflow step?

  A. Configure a self-hosted runner on Windows with the requested tools.
  B. Use the YAML powershell: step.
  C. Run the pwsh2bash command to convert the script so it can be run on Linux.
  D. Use the YAML shell: pwsh in a run step.
  E. Use the actions/run-powershell action to invoke the script.
  D. Use the YAML shell: pwsh in a run step.

  ---

  Since the self-hosted runner is configured on a Linux VM and the script is written in PowerShell, you can invoke the script using the pwsh (PowerShell Core) shell in a run step in the workflow. This ensures that the script runs as-is on the Linux runner, as PowerShell Core (pwsh) is cross-platform and supports Linux.

• Question 44:

  Where should workflow files be stored to be triggered by events in a repository?

  A. .github/workflows/
  B. .github/actions/
  C. Nowhere; they must be attached to an act on in the GitHub user interface
  D. anywhere
  E. .workflows/
  A. .github/workflows/

  ---

  Workflow files must be stored in the .github/workflows/ directory of the repository. This is the standard location for GitHub Actions workflow files, and workflows in this directory are automatically triggered by events defined in the file, such as pushes, pull requests, or other GitHub events.

• Question 45:

  Based on the YAML below, which two statements are correct? (Choose two.)

  

  A. This workflow will publish a package to an npm registry.
  B. This workflow will publish a package to GitHub Packages.
  C. This workflow file is using a matrix strategy.
  D. The workflow job publish-npm will only run after the build job passes.
  A. This workflow will publish a package to an npm registry.
  D. The workflow job publish-npm will only run after the build job passes.

  ---

  The publish-npm job includes the JS-DevTools/npm-publish action, which is used to publish an npm package to an npm registry. The publish-npm job has the needs: build directive, meaning it will only run after the build job successfully completes.

• Question 46:

  As a developer, your self-hosted runner sometimes looses connection while running jobs. How should you troubleshoot the issue affecting your self-hosted runner?

  A. Set the DEBUG environment variable to true before starting the self-hosted runner to produce more verbose console output.
  B. Locate the self-hosted runner in your repository's settings page and download its log archive.
  C. Access the self-hosted runner's installation directory and look for log files in the _diag folder.
  D. Start the self-hosted runner with the --debug flag to produce more verbose console output.
  C. Access the self-hosted runner's installation directory and look for log files in the _diag folder.

  ---

  When troubleshooting a self-hosted runner, you can access the_diagfolder located in the self-hosted runner's installation directory. This folder contains diagnostic logs that can help you identify the root cause of issues, such as connection problems.

• Question 47:

  What are the two ways to pass data between jobs? (Choose two.)

  A. Use the copy action with restore parameter to restore the data from the cache
  B. Use the copy action to save the data that should be passed in the artifacts folder.
  C. Use the copy action with cache parameter to cache the data
  D. Use data storage.
  E. Use job outputs
  F. Use artifact storage.
  E. Use job outputs
  F. Use artifact storage.

  ---

  Job outputs are used to pass data from one job to another in a workflow. A job can produce output values (like variables or files), which can be referenced by subsequent jobs using theneedskeyword and${{ steps.step_id. outputs.output_name }}syntax.

  Artifact storage allows data (such as files or results) to be saved by a job and then retrieved by another job in a later step. This is commonly used for passing large amounts of data or files between jobs.

• Question 48:

  Which of the following scenarios requires a developer to explicitly use the GITHUB_TOKEN or github.token secret within a workflow? (Choose two.)

  A. passing the GITHUB_TOKEN secret to an action that requires a token as an input
  B. making an authenticated GitHub API request
  C. checking out source code with the actions/checkout@v3 action
  D. assigning non-default permissions to the GITHUB_TOKEN
  A. passing the GITHUB_TOKEN secret to an action that requires a token as an input
  B. making an authenticated GitHub API request

  ---

  Some actions may require a GITHUB_TOKEN as an input to authenticate and perform specific tasks, such as creating issues, commenting on pull requests, or interacting with the GitHub API. In such cases, you would need to explicitly pass the token to the action. When making an authenticated GitHub API request, the GITHUB_TOKEN is required to authenticate the request. This token is automatically provided by GitHub in the workflow, and it must be explicitly used when interacting with the GitHub API.

• Question 49:

  Which choices represent best practices for publishing actions so that they can be consumed reliably? (Choose two.)

  A. repo name
  B. tag
  C. commit SHA
  D. organization name
  E. default branch
  B. tag
  C. commit SHA

  ---

  Using a tag is a best practice because tags are immutable and represent a fixed version of your action. By referencing tags, consumers of your action can be assured they are using a stable and specific version of the action, which helps in avoiding issues with breaking changes. The commit SHA is another reliable way to specify a particular version of an action. By referencing a specific commit SHA, consumers can ensure they are using exactly the code that was written at that moment, avoiding the potential for changes in the future.

• Question 50:

  As a developer, what options should you recommend to implement standards for automation reuse? (Choose two.)

  A. Create workflow templates and store them in the organization's .github repository.
  B. Create reusable actions and workflows that can be called from other workflows.
  C. Create a marketplace partition to publish reusable automation for the company.
  D. Store shared corporate actions in subfolders in a defined and documented internally accessible repository.
  A. Create workflow templates and store them in the organization's .github repository.
  B. Create reusable actions and workflows that can be called from other workflows.

  ---

  Creating workflow templates in the organization's .github repository allows the organization to standardize workflows and make them easily reusable across multiple repositories. This ensures consistency and simplifies maintenance.

  Creating reusable actions and workflows that can be called from other workflows helps modularize and standardize automation tasks. These reusable components can be maintained centrally and called from different workflows across repositories.
