Q35. 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?

Q36. What are the two ways to pass data between jobs? (Choose two.)

Use the copy action with restore parameter to restore the data from the cache

Use the copy action to save the data that should be passed in the artifacts folder.

Use the copy action with cache parameter to cache the data

Use data storage.

Use job outputs

Use artifact storage.

Q37. How can GitHub Actions encrypted secrets be used in if: conditionals within a workflow job?

Set the encrypted secret as a job-level environment variable and then reference the environment variable within the conditional statement.

Create a job dependency that exposes the encrypted secret as a job output, which can then be leveraged in a subsequent dependent job.

Use the secrets context within the conditional statement, e.g. ${{ secrets.MySuperSecret }}.

Use a workflow command to expose the encrypted secret via a step’s output parameter and then use the step output in the job’s if: conditional.

Q38. Without the need to use additional infrastructure, what is the simplest and most maintainable method for configuring a workflow job to provide access to an empty PostgreSQL database?

Use service containers with a Postgres database from Docker hub.

Run the actions/postgres action in a parallel job.

It is currently impossible to access the database with GitHub Actions.

Dynamically provision and deprovision an environment.

Q39. What menu options in a repository do you need to select in order to use a starter workflow that is provided by your organization?

Actions > Load workflow

Workflow > New workflow

Workflow > Load workflow

Actions > New workflow

Q40. GitHub-hosted runners support which capabilities? (Choose two.)

automatic patching of both the runner and the underlying OS

automatic file-system caching between workflow runs

support for Linux, Windows, and mac

support for a variety of Linux variations including CentOS, Fedora, and Debian

requiring a payment mechanism (e.g., credit card) to use for private repositories

Q41. Which syntax correctly accesses a job output (output1) of an upstream job (job1) from a dependent job within a workflow?

${{needs.job1.outputs.output1}}

${{needs.job1.output1}}

${{depends.job1.output1}}

${{job1.outputs.output1}}

Q42. As a DevOps engineer, you are trying to leverage an organization secret in a repo. The value received in the workflow is not the same as that set in the secret. What is the most likely reason for the difference?

There is a different value specified at the rego level.

There is a different value specified at the workflow level.

The Codespace secret doesn’t match the expected value.

The Encrypt Secret setting was not configured for the secret.

There is a different value specified at the enterprise level.

Q43. Which workflow command would output the debug message “action successfully debugged”?

echo :debug::message=action successfully debugged”

echo “debug-action successfully debugged”

echo “::debug::action successfully debugged”

echo “:debug:action successfully debugged:”

Q44. 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?

Configure a self-hosted runner on Windows with the requested tools.

Use the YAML powershell: step.

Run the pwsh2bash command to convert the script so it can be run on Linux.

Use the YAML shell: pwsh in a run step.

Use the actions/run-powershell action to invoke the script.

Q45. As a developer, what is the safest way to reference an action to prevent modification of the underlying code?

Use a commit hash.

Use a branch name.

Use a patch release tag.

Use a major release tag.

Q46. Where should workflow files be stored to be triggered by events in a repository?

.github/workflows/

.github/actions/

Nowhere; they must be attached to an act on in the GitHub user interface

anywhere

.workflows/

Q47. When creating and managing custom actions in an enterprise setting, which of the following is considered a best practice?

creating a separate repository for each action so that the version can be managed independently

creating a separate branch in application repositories that only contains the actions

creating a single repository for all custom actions so that the versions for each action are all the same

including custom actions that other teams need to reference in the same repository as application code

Q48. What is the smallest scope for an environment variable?

the workflow settings

a step

a job

the workflow env mapping

Q49. As a developer, which workflow steps should you perform to publish an image to the GitHub Container Registry? (Choose three.)

Use the actions/setup-docker action

Authenticate to the GitHub Container Registry.

Build the container image.

Push the image to the GitHub Container Registry

Pull the image from the GitHub Container Registry.

Q50. Which of the following scenarios would require the use of self-hosted runners instead of GitHub-hosted runners?

running more than the three concurrent workflows supported by GitHub-hosted runners

exceeding 50,000 monthly minutes of build time

using Docker containers as part of the workflow

using specialized hardware configurations required for workflows

performing builds on macOS

Q51. As a developer, you need to integrate a GitHub Actions workflow with a third-party code quality provider that uses the Checks API. How should you trigger a follow-up workflow?

Add the workflow_run webhook event as a trigger for the workflow for the code quality integration name

Add the check_run webhook event as a trigger for the workflow when the code quality integration is completed

Add the pull_request webhook event as a trigger for the workflow when the code quality integration is synchronized

Add the deployment webhook event as a trigger for the workflow when the code quality integration is completed

Q52. As a developer, how can you identify a Docker container action on GitHub?

The action’s repository includes @actions/core in the root directory.

The action’s repository name includes the keyword “Docker.”

The action.yml metadata file references a Dockerfile file.

The action.yml metadata file has the runs.using value set to Docker.

Q53. Based on the YAML below, which two statements are correct? (Choose two.)

This workflow will publish a package to an npm registry.

This workflow will publish a package to GitHub Packages.

This workflow file is using a matrix strategy.

The workflow job publish-npm will only run after the build job passes.

Q54. In which locations can actions be referenced by workflows? (Choose three.)

a separate public repository

an .action extension file in the repository

the same repository as the workflow

a published Docker container image on Docker Hub

the runs-on: keyword of a workflow file
