Question 1

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.)

AA workflow sends requests to a service that is down.

BA workflow error produces too many, or wrong, requests, impacting external services negatively.

CA workflow is configured to run on self-hosted runners

DA workflow needs to be changed from running on a schedule to a manual trigger

EA runner needs to have diagnostic logging enabled.

Answer : A, B

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.

Question 2

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

A.github/workflows/

B.github/actions/

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

Danywhere

E.workflows/

Answer : A

Workflow files must be stored in the .github/workflows/ directory of the repository. This is the standard location for GitHub Actions workflow files, and workflows in this directory are automatically triggered by events defined in the file, such as pushes, pull requests, or other GitHub events.

Question 3

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

AThe action's repository includes @actions/core in the root directory.

BThe action's repository name includes the keyword 'Docker.'

CThe action.yml metadata file references a Dockerfile file.

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

Answer : D

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.

Question 4

How should you install the bats NPM package in your workflow?

AOption A

BOption B

COption C

DOption D

Answer : D

The correct syntax includes specifying the job (example-job), the runner (ubuntu-latest), and the necessary step (npm install -g bats) within the workflow. This ensures that the package is installed properly during the execution of the job.

Question 5

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.)

AStore the token in a configuration file in a private repository. Use GitHub Actions to deploy the configuration file to the runtime environment.

BStore the token as a GitHub encrypted secret in the same repo as the code. Create a reusable custom GitHub Action to access the token by the microservice at runtime.

CUse a corporate non-GitHub secret store (e.g., HashiCorp Vault) to store the token. During deployment, use GitHub Actions to store the secret in an environment variable that can be accessed at runtime.

DStore the token as a GitHub encrypted secret in the same repo as the code. During deployment, use GitHub Actions to store the secret in an environment variable that can be accessed at runtime.

EStore the token as an organizational-level encrypted secret in GitHub. During deployment, use GitHub Actions to store the secret in an environment variable that can be accessed at runtime.

Answer : C, E

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.

Question 6

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?

AOption A

BOption B

COption C

DOption D

Answer : 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 with type: choice and includes the option value: functional, which aligns with the visible UI elements in the first image.

Question 7

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?

Aself-hosted: [windows-x64]

Bruns-on: [self-hosted, windows, x64]

Cruns-on: windows-latest

Dself-hosted: [windows, x64]

Answer : B

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.
