GitHub GITHUB-ACTIONS Online Practice Questions and Exam Preparation

GitHub GITHUB-ACTIONS Online Questions & Answers

• Question 1:

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

  A. Actions > Load workflow
  B. Workflow > New workflow
  C. Workflow > Load workflow
  D. Actions > New workflow
  D. Actions > New workflow

  ---

  explanation:

  To use a starter workflow provided by your organization, you need to go to the Actions tab in the repository and select New workflow. This option allows you to either create a new workflow or select from a list of available workflow templates, including starter workflows provided by your organization.

• Question 2:

  Which action type should be used to bundle a series of run steps into a reusable custom action?

  A. Composite action
  B. Bash script action
  C. Docker container action
  D. JavaScript action
  A. Composite action

  ---

  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.

• Question 3:

  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?

  A. There is a different value specified at the rego level.
  B. There is a different value specified at the workflow level.
  C. The Codespace secret doesn't match the expected value.
  D. The Encrypt Secret setting was not configured for the secret.
  E. There is a different value specified at the enterprise level.
  A. There is a different value specified at the rego level.

  ---

  explanation:

  GitHub secrets are defined at different levels: organization, repository, and sometimes at the workflow level. If a secret is defined at both the organization level and the repository level, the repository-level secret will take precedence. So, if the value of the secret differs between these levels, the workflow will use the value from the repository level instead of the organization level.

• Question 4:

  As a DevOps engineer developing a JavaScript action, you need to include annotations to pass warning messages to workflow runners. Which code snippet can you use to implement an annotation in your Actions?

  A. core.info('Something went wrong, but it\'s not bad enough to fail the build.')
  B. core.notice('Something went wrong, but it\'s not bad enough to fail the build.')
  C. core.warning('Something went wrong, but it\'s not bad enough to fail the build.')
  D. core.warn('Something went wrong, but it\'s not bad enough to fail the build.')
  C. core.warning('Something went wrong, but it\'s not bad enough to fail the build.')

  ---

  explanation:

  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.

• Question 5:

  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 cachingwhen reusing files that change rarely between jobs or workflow runs.
  B. Use artifacts when referencingfiles produced by a job after a workflow has ended.
  C. Use caching to store cache entries for up to 30 days between accesses.
  D. Use artifacts to access theGitHub Package Registry and download a package for a workflow
  A. Use cachingwhen reusing files that change rarely between jobs or workflow runs.
  B. Use artifacts when referencingfiles produced by a job after a workflow has ended.

  ---

  explanation:

  Caching is ideal for files that change rarely, such as dependencies or build outputs, as it speeds up subsequent workflow runs by reusing previously cached files instead of re-downloading or rebuilding them. Artifacts are used for persisting files produced during a job that need to be used in later jobs or after the workflow has ended, allowing them to be downloaded or referenced later.

• Question 6:

  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. Create the group custom-software-on-linux and move the runner into the group.
  B. Inform users to identify the runner based on the group.
  C. Add the label custom-software to the runner.
  D. Configure the webhook and network to enable GitHub to trigger workflow.
  E. Add the label linux to the runner.
  B. Inform users to identify the runner based on the group.
  C. Add the label custom-software to the runner.

  ---

  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.

• Question 7:

  Scheduled workflows in GitHub Actions run on the _______.

  A. latest commit and branch on which the workflow was triggered
  B. latest commit from the branch named schedule
  C. latest commit from the branch named main
  D. specified commit and branch from the workflow YAML file
  E. latest commit on the default or base branch
  A. latest commit and branch on which the workflow was triggered

  ---

  explanation:

  Scheduled workflows in GitHub Actions are triggered automatically at specified times defined in the on.schedule event. They always run on the latest commit of the default branch (usually main or master) unless another branch is explicitly defined in the workflow configuration. In other words, when the schedule event occurs, the workflow runs using the latest commit on the branch that triggers the workflow, typically the default branch.

• Question 8:

  As a developer, you are designing a workflow and need to communicate with the runner machine to set environment variables, output values used by other actions, add debug messages to the output logs, and other tasks. Which of the following options should you use?

  A. environment variables
  B. workflow commands
  C. self-hosted runners
  D. enable debug logging
  E. composite run step
  B. workflow commands

  ---

  explanation:

  Workflow commands are special commands that allow you to interact with the runner, set environment variables, output values, add debug messages, and perform other tasks within the workflow. These commands are used to modify the environment or influence the behavior of the GitHub Actions runner.

• Question 9:

  Which workflow event is used to manually trigger a workflow run?

  A. create
  B. workflow_dispatch
  C. workflow_run
  D. status
  B. workflow_dispatch

  ---

  explanation:

  The workflow_dispatch event is used to manually trigger a workflow run in GitHub Actions. You can specify this event in the workflow file to allow users to manually trigger the workflow from the GitHub UI, often with optional input parameters.

• Question 10:

  As a DevOps engineer, you are developing a container action. You need to execute a cleanup script after completing the main script execution. Which code block should be used to define the cleanup script?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

  ---

  explanation:

  The correct syntax for specifying a cleanup script to be run after the main entry point is executed in a Docker- based GitHub Action is to use thepostkey. This ensures thatcleanup.shruns after the main script (main.sh) has completed.
