GitHub GITHUB-ACTIONS Online Practice Questions and Exam Preparation

GitHub GITHUB-ACTIONS Online Questions & Answers

• Question 1:

  Which syntax correctly accesses a job output (output1) of an upstream job (job1) from a dependent job within a workflow?

  A. ${{needs.job1.outputs.output1}}
  B. ${{needs.job1.output1}}
  C. ${{depends.job1.output1}}
  D. ${{job1.outputs.output1}}
  A. ${{needs.job1.outputs.output1}}

  ---

  Theneedscontext is used to reference the outputs of jobs that are dependencies of the current job. In this case, needs.job1.outputs.output1correctly accesses the output ofoutput1from the jobjob1in the dependent job.

• Question 2:

  Your organization is managing secrets using GitHub encrypted secrets, including a secret named SuperSecret. As a developer, you need to create a version of that secret that contains a different value for use in a workflow that is scoped to a specific repository named MyRepo. How should you store the secret to access your specific version within your workflow?

  A. Create a duplicate entry for SuperSecret in the encrypted secret store and specify MyRepo as the scope.
  B. Create MyRepo_SuperSecret in GitHub encrypted secrets to specify the scope to MyRepo.
  C. Create a file with the SuperSecret. information in the .qithub/secrets folder in MyRepo.
  D. Create and access SuperSecret from the secrets store in MyRepo.
  B. Create MyRepo_SuperSecret in GitHub encrypted secrets to specify the scope to MyRepo.

  ---

  To scope a secret to a specific repository, you can create a new secret with a name likeMyRepo_SuperSecretin thesecretssection of theMyReporepository's settings. This ensures that the secret is specific to that repository and can be used within its workflows.

• Question 3:

  As a developer, you want to run a workflow from the Actions tab in GitHub. Which YAML snippet should you use to match the interface in this image?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  C. Option C

  ---

  The first image shows a workflow trigger with an option for the test suite, and the chosen YAML configuration matches this interface. Specifically, the test suite input is defined withtype: choiceand includes the optionvalue: functional, which aligns with the visible UI elements in the first image.

• Question 4:

  Which run: command will set a step's output?

  A. run: echo "MY_OUTPUT=foo" >> $GITHUB_OUTPUT
  B. run: export MY_OUTPUT=foo
  C. run: echo ${{ $GITHUB_OUTPUT=foo }}
  D. run: echo "::set-env name=MY OUTPUT::foo"
  A. run: echo "MY_OUTPUT=foo" >> $GITHUB_OUTPUT

  ---

  The $GITHUB_OUTPUT file is used to pass data from one step to another in GitHub Actions. The echo command appends the key-value pair to this file, which sets the output variable (MY_OUTPUT) for the current step.

• Question 5:

  In which locations can actions be referenced by workflows? (Choose three.)

  A. a separate public repository
  B. an .action extension file in the repository
  C. the same repository as the workflow
  D. a published Docker container image on Docker Hub
  E. the runs-on: keyword of a workflow file
  F. the repository's Secrets settings page
  G. a public NPM registry
  A. a separate public repository
  C. the same repository as the workflow
  D. a published Docker container image on Docker Hub

  ---

  Actions can be stored in a separate public repository and referenced in workflows by specifying the repository and action name.

  Actions can also be stored in the same repository as the workflow and referenced directly by their path (e.g., ./.github/actions/my-action).

  Actions can be packaged as Docker container images and published to Docker Hub. These can then be referenced in workflows by specifying the Docker image.

• Question 6:

  As a DevOps engineer developing a JavaScript action, you need to include annotations to pass warning messages to workflow runners. Which code snippet can you use to implement an annotation in your Actions?

  A. core.info('Something went wrong, but it\'s not bad enough to fail the build.')
  B. core.notice('Something went wrong, but it\'s not bad enough to fail the build.')
  C. core.warning('Something went wrong, but it\'s not bad enough to fail the build.')
  D. core.warn('Something went wrong, but it\'s not bad enough to fail the build.')
  C. core.warning('Something went wrong, but it\'s not bad enough to fail the build.')

  ---

  Thecore.warning()function from the@actions/corepackage is used to create a warning message in the workflow logs. This is an annotation type that informs users about issues that don't require failing the build but still need attention.

• Question 7:

  Which statement correctly describes the behavior of the if: conditional in GitHub Actions?

  A. It is only valid at the workflow level.
  B. It can be used to control whether a job or step runs.
  C. It can only be applied to steps that use the run key.
  D. It executes after all steps in the job have completed.
  B. It can be used to control whether a job or step runs.

  ---

  The if: conditional allows control over whether a specific job or step executes. It evaluates a boolean expression at runtime, enabling developers to implement logic such as skipping steps when a build fails or running steps only on specific branches.

• Question 8:

  You are reaching your organization's storage limit for GitHub artifacts and packages. What should you do to prevent the storage limit from being reached?

  A. via the .github repository owned by the organization
  B. via repositories owned by the organization
  C. via the GitHub Marketplace
  D. via a repository owned by a third party
  B. via repositories owned by the organization

  ---

  To prevent reaching the storage limit for GitHub artifacts and packages, you should manage and clean up artifacts and packages stored in repositories owned by your organization. This includes deleting unnecessary artifacts and managing the lifecycle of packages, as they contribute directly to your organization's storage quota.

• Question 9:

  Which of the following commands will set the $FOO environment variable within a script, so that it may be used in subsequent workflow job steps?

  A. run: echo "::set-env name=FOO::bar"
  B. run: echo "FOO=bar" >> $GITHUB_ENV
  C. run: echo ${{ $FOO=bar }}
  D. run: export FOO=bar
  B. run: echo "FOO=bar" >> $GITHUB_ENV

  ---

  The $GITHUB_ENV environment variable is used to set environment variables that persist across steps in a workflow job. By echoing FOO=bar into $GITHUB_ENV, the variable FOO will be available in subsequent steps within the same job.

• Question 10:

  Which action type should be used to bundle a series of run steps into a reusable custom action?

  A. Composite action
  B. Bash script action
  C. Docker container action
  D. JavaScript action
  A. Composite action

  ---

  A composite action allows you to bundle multiple steps into a single reusable action within a workflow. It is composed of multiple run steps or other actions and can be reused across workflows, making it the perfect choice for bundling a series of steps.
