You installed specific software on a Linux self-hosted runner. You have users with workflows that need to be able to select the runner based on the identified custom software. Which steps should you perform to prepare the runner and your users to run these workflows? (Choose two.)
- A. Add the label linux to the runner.
- B. Configure the webhook and network to enable GitHub to trigger workflow.
- C. Inform users to identify the runner based on the group.
- D. Create the group custom-software-on-linux and move the runner into the group.
- E. Add the label custom-software to the runner.
Answer: C,E
Explanation:
Once the runner is properly configured and labeled, users should be informed to select the specific runner by identifying the label or group name when defining the runner in their workflows.
Adding a custom label (likecustom-software) to the runner makes it easier for users to select the runner in their workflows by using theruns-onkey, which allows them to choose this specific runner based on its label.

NEW QUESTION # 33
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?
- A. Dynamically provision and deprovision an environment.
- B. It is currently impossible to access the database with GitHub Actions.
- C. Use service containers with a Postgres database from Docker hub.
- D. Run the actions/postgres action in a parallel job.
Answer: C
Explanation:
GitHub Actions supports the use of service containers, which allows you to spin up a PostgreSQL database (or any other service) in a Docker container during your workflow. You can pull a PostgreSQL image from Docker Hub, and the container will automatically be available to your workflow job. This method requires no additional infrastructure and is easy to configure and maintain, as you simply define the container in the workflow file.
NEW QUESTION # 34
As a developer, you are optimizing a GitHub workflow that uses and produces many different files. You need to determine when to use caching versus workflow artifacts. Which two statements are true? (Choose two.)
- A. Use artifacts when referencingfiles produced by a job after a workflow has ended.
- B. Use artifacts to access theGitHub Package Registry and download a package for a workflow
- C. Use caching to store cache entries for up to 30 days between accesses.

NEW QUESTION # 35
Which action type should be used to bundle a series of run steps into a reusable custom action?
- A. Composite action
- B. Docker container action
- C. JavaScript action
- D. Bash script action
Answer: A
Explanation:
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.
NEW QUESTION # 36
Disabling a workflow allows you to stop a workflow from being triggered without having to delete the file from the repo. In which scenarios would temporarily disabling a workflow be most useful? (Choose two.)
- A. A workflow is configured to run on self-hosted runners
- B. A workflow sends requests to a service that is down.
- C. A workflow needs to be changed from running on a schedule to a manual trigger
- D. A workflow error produces too many, or wrong, requests, impacting external services negatively.
- E. A runner needs to have diagnostic logging enabled.
Answer: B,D
Explanation:
If a workflow depends on an external service that is down, disabling the workflow temporarily will prevent it from running and sending requests to the service, thus avoiding failed requests or unnecessary retries.
If a workflow is causing a negative impact on external services by generating too many requests or incorrect data due to a bug, temporarily disabling the workflow will stop this behavior while the issue is fixed.
NEW QUESTION # 37
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?
- A. Add the pull_request webhook event as a trigger for the workflow when the code quality integration is synchronized
- B. Add the check_run webhook event as a trigger for the workflow when the code quality integration is completed
- C. Add the workflow_run webhook event as a trigger for the workflow for the code quality integration name
- D. Add the deployment webhook event as a trigger for the workflow when the code quality integration is completed
Answer: B
Explanation:
Thecheck_runevent is triggered when a check (such as a code quality check) completes, including when the status of a check changes. By adding this event as a trigger, you can initiate a follow-up workflow when the code quality integration finishes its checks.
NEW QUESTION # 38
You have exactly one Windows x64 self-hosted runner, and it is configured with custom tools. Which syntax could you use in the workflow to target that runner?
- A. runs-on: [self-hosted, windows, x64]
- B. self-hosted: [windows, x64]
- C. runs-on: windows-latest
- D. self-hosted: [windows-x64]
Answer: A
Explanation:
The runs-on keyword allows you to specify the operating system and other labels for the runner. By specifying self-hosted, windows, and x64, you are targeting a self-hosted Windows runner that matches these criteria, which aligns with the custom configuration of your self-hosted runner.
NEW QUESTION # 39
Which default environment variable specifies the branch or tag that triggered a workflow?
- A. GITHUB_TAG
- B. GITHUB_REF
- C. GITHUB_BRANCH
- D. ENV_BRANCH
Answer: B
Explanation:
The GITHUB_REF environment variable specifies the branch or tag that triggered the workflow. It contains the full reference to the branch or tag, such as refs/heads/main for a branch or refs/tags/v1.0 for a tag.
NEW QUESTION # 40
GitHub-hosted runners support which capabilities? (Choose two.)
- A. automatic patching of both the runner and the underlying OS
- B. automatic file-system caching between workflow runs
- C. requiring a payment mechanism (e.g., credit card) to use for private repositories
- D. support for a variety of Linux variations including CentOS, Fedora, and Debian
- E. support for Linux, Windows, and mac
Answer: D,E
Explanation:
GitHub-hosted runners automatically handle patching, meaning they will be kept up to date with the latest security updates and software patches for both the runner environment and the underlying operating system.
GitHub-hosted runners support Linux, Windows, and macOS, giving you flexibility to run workflows on different operating systems without needing to manage your own self-hosted runners.
NEW QUESTION # 41
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? (Choose two.)
- A. Configure the artifact and log retention period.
- B. Disable branch protections in the repository.
- C. Configure the repo to use Git Large File Storage.
- D. Delete artifacts from the repositories manually
- E. Use self-hosted runners for all workflow runs.
Answer: A,D
Explanation:
Deleting artifacts from repositories manually will free up storage space. Artifacts are typically stored for a limited time by default, but manual cleanup can help manage space.
Configuring the artifact and log retention period allows you to control how long artifacts and logs are retained in your repository. By shortening the retention period, you can prevent unnecessary accumulation of data and manage storage more effectively.
