GitHub GITHUB-ACTIONS Online Questions & Answers

• Question 81:

  As a developer, you are using a Docker container action in your workflow. What is required for the action to run successfully?

  A. The job env must be set to a Linux environment.
  B. The job runs-on must specify a Linux machine with Docker installed.
  C. The referenced action must be hosted on Docker Hub.
  D. The action must be published to the GitHub Marketplace.
  B. The job runs-on must specify a Linux machine with Docker installed.

  ---

  For a Docker container action to run in a GitHub Actions workflow, the runner must have Docker installed. The runs-on attribute of the job should specify an environment that supports Docker, typically a Linux environment (e.g., ubuntu-latest), since Docker is widely supported and commonly used in Linux-based environments.

• Question 82:

  How should you install the bats NPM package in your workflow?

  

  A. jobs: example-job: steps: -npm install -g bats
  B. jobs: steps: -run: npm install -g bats
  C. jobs: runs-on: ubuntu-latest -run: npm install -g bats
  D. jobs: example-job: runs-on: ubuntu-latest steps: -run: npm install -g bats
  D. jobs: example-job: runs-on: ubuntu-latest steps: -run: npm install -g bats

  ---

  The correct syntax includes specifying the job (example-job), the runner (ubuntu-latest), and the necessary step (npm install -g bats) within the workflow. This ensures that the package is installed properly during the execution of the job.

• Question 83:

  Which statement is true about using default environment variables?

  A. The environment variables can be read in workflows using the ENV: variable_name syntax.
  B. The environment variables created should be prefixed with GITHUB_ to ensure they can be accessed in workflows
  C. The environment variables can be set in the defaults: sections of the workflow
  D. The GITHUB_WORKSPACE environment variable should be used to access files from within the runner.
  D. The GITHUB_WORKSPACE environment variable should be used to access files from within the runner.

  ---

  GITHUB_WORKSPACE is a default environment variable in GitHub Actions that points to the directory on the runner where your repository is checked out. This variable allows you to access files within your repository during the workflow.

• Question 84:

  As a developer, you need to make sure that only actions from trusted sources are available for use in your GitHub Enterprise Cloud organization. Which of the following statements are true? (Choose three.)

  A. Specific actions can individually be enabled for the organization, including version information.
  B. GitHub-verified actions can be collectively enabled for use in the enterprise.
  C. Actions can be restricted to only those available in the enterprise.
  D. Actions created by GitHub are automatically enabled and cannot be disabled.
  E. Individual third-party actions enabled with a specific tag will prevent updated versions of the action from introducing vulnerabilities.
  F. Actions can be published to an internal marketplace.
  A. Specific actions can individually be enabled for the organization, including version information.
  B. GitHub-verified actions can be collectively enabled for use in the enterprise.
  F. Actions can be published to an internal marketplace.

  ---

  You can enable specific actions for the organization by identifying them and providing version control, ensuring only trusted versions are used in workflows. GitHub-verified actions can be enabled at the enterprise level, providing an extra layer of security by ensuring that only trusted actions are available to workflows. Actions can be published to an internal marketplace, allowing organizations to share reusable actions securely within their enterprise without exposing them to the public.
