NEW QUESTION # 37
Which scopes are available to define custom environment variables within a workflow file? (Choose three.)
- A. the contents of a job within a workflow, by using jobs.<job_id>.env
- B. within the run attribute of a job step
- C. all jobs being run on a single Actions runner, by using runner.env at the top of the workflow file
- D. a specific step within a job, by using jobs.<job_id>.steps[*].env
- E. the entire stage, by using env at the top of the defined build stage
- F. the entire workflow, by using env at the top level of the workflow file
Answer: B,D,F
Explanation:
You can define environment variables for the entire workflow by using the env key at the top level of the workflow file. These environment variables will be available to all jobs and steps within the workflow.
Environment variables can also be set within the run attribute of a job step, and these variables will be scoped only to that specific step.
You can set environment variables for specific steps within a job by using jobs.<job_id>.steps[*].env, which allows you to define variables that will only be available to that step.
NEW QUESTION # 38
Which run: command will set a step's output?

- C. run: echo "::set-env name=MY OUTPUT::foo"
- D. run: echo "MY_OUTPUT=foo" >> $GITHUB_OUTPUT
Answer: D
Explanation:
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.
NEW QUESTION # 39
What metadata file in a custom action defines the main entry point?

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.
NEW QUESTION # 46
As a developer, you are using a Docker container action in your workflow. What is required for the action to run successfully?
- A. The action must be published to the GitHub Marketplace.
- B. The job env must be set to a Linux environment.
- C. The referenced action must be hosted on Docker Hub.
- D. The job runs-on must specify a Linux machine with Docker installed.
Answer: D
Explanation:
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.
NEW QUESTION # 47
What are the two ways to pass data between jobs? (Choose two.)
- A. Use job outputs
- B. Use the copy action to save the data that should be passed in the artifacts folder.
