What is a role of GitHub Marketplace when using GitHub Actions?
GitHub Marketplace is used to discover, share, and publish reusable automation, including GitHub Actions created by GitHub, vendors, and the community. Option C best describes this role. Marketplace does not exist only for billing, so option B is too narrow and incorrect. Option A is also wrong because Marketplace does not merely restrict third-party actions to public repositories; action usage is governed by repository, organization, or enterprise Actions policies. Option D is false because Marketplace does not bypass repository permissions or automatically deploy workflows into repositories. In exam terms, Marketplace is part of the automation reuse and action discovery domain: developers use it to find trusted or verified actions rather than building every integration manually. GitHub documents Marketplace as a place to publish and share actions with the community.
As a developer, how can you identify a Docker container action on GitHub?
In a Docker container action, the action.yml file includes the runs.using field, which is set to docker to specify that the action runs inside a Docker container. This is the key indicator that the action is a Docker container action.
As a developer, you need to use GitHub Actions to deploy a microservice that requires runtime access to a secure token. This token is used by a variety of other microservices managed by different teams in different repos. To minimize management overhead and ensure the token is secure, which mechanisms should you use to store and access the token? (Choose two.)
Using a corporate secret store like HashiCorp Vault provides a secure, centralized location for sensitive information. GitHub Actions can then retrieve and store the token securely during deployment by setting it as an environment variable, ensuring the token remains secure and accessible at runtime.
Storing the token as an organizational-level encrypted secret in GitHub ensures it is accessible across multiple repositories, minimizing management overhead. GitHub Actions can then use this secret during deployment by setting it as an environment variable, allowing the microservice to access it securely at runtime.

As a developer, you want to review the step that caused a workflow failure and the failed step's build logs. First navigate to the main page of the repository on GitHub. Which section contains the step failure information?
The Actions tab on the main page of the repository is where you can find detailed information about the workflow runs, including step failures and build logs. You can review the status of each job and step within the workflow, see the failure messages, and access logs for debugging.
