• Question 81:

  In which of the following scenarios should you use self-hosted runners? (Each correct answer presents a complete solution. Choose two.)

  A. when the workflow jobs must be run on Windows 10
  B. when jobs must run for longer than 6 hours
  C. when a workflow job needs to install software from the local network
  D. when GitHub Actions minutes must be used for the workflow runs
  E. when you want to use macOS runners
  B. when jobs must run for longer than 6 hours
  C. when a workflow job needs to install software from the local network

  ---

  Explanation

  [B] You can use self-hosted runner to run more than 6 hours job.

  Self-hosted runners give you the opportunity to persist whatever you like for your jobs and not be subject to the six-hour time-out in hosted virtual environments.

  [C] Give you more control of hardware, operating system, and software tools than GitHub-hosted runners provide.

  All runners can run Linux, Windows, or macOS.

  Incorrect:

  [Not A, not E]

  GitHub-hosted runners are fully managed on GitHub’s infrastructure using pre-configured Windows, Linux, and macOS virtual machines. In addition to offering standard runners for typical workloads, hosted runners offer larger runners with

  more resources (memory, CPU, and storage), custom images, static IP ranges, and Azure Virtual Network integration for enhanced security control.

  [Not D]

  GitHub Actions minutes refer to the amount of time your workflows, such as CI/CD pipelines, run on GitHub's hosted runners. Each time you trigger GitHub Actions (e.g., for testing, building, or deploying code), it consumes a portion of your

• Question 82:

  By default, which workflows can use an action stored in internal repository? (Each answer presents a complete solution. Choose two.)

  A. selected public repositories outside of the enterprise
  B. internal repositories owned by the same organization as the enterprise
  C. public repositories owned by the same organization as the enterprise
  D. private repositories owned by an organization of the enterprise
  B. internal repositories owned by the same organization as the enterprise
  D. private repositories owned by an organization of the enterprise

  ---

  Explanation

  Any actions or reusable workflows stored in the internal or private repository can be used in workflows defined in other internal or private repositories owned by the same organization, or by any organization owned by the enterprise.

• Question 83:

  Your organization is managing secrets using GitHub encrypted secrets, including a secret named SuperSecret. As a developer, you need to create a version of that secret that contains a different value for use in a workflow that is scoped to a specific repository named MyRepo. How should you store the secret to access your specific version within your workflow?

  A. Create MyRepo_SuperSecret in GitHub encrypted secrets to specify the scope to MyRepo.
  B. Create a duplicate entry for SuperSecret in the encrypted secret store and specify MyRepo as the scope.
  C. Create a file with the SuperSecret information in the .github/secrets folder in MyRepo.
  D. Create and access SuperSecret from the secrets store in MyRepo.
  B. Create a duplicate entry for SuperSecret in the encrypted secret store and specify MyRepo as the scope.

• Question 84:

  While writing a custom action, some behavior within the runner must be changed. Which workflow commands would set an error message in the runner’s output? (Each correct answer presents a complete solution. Choose two.)

  A. echo "::error file=main.py,line=10,col=15::There was an error"
  B. echo "::error=There was an error::"
  C. echo "::error::There was an error"
  D. echo "::error message=There was an error::"
  A. echo "::error file=main.py,line=10,col=15::There was an error"
  C. echo "::error::There was an error"

  ---

  Explanation

  To set an error message in a GitHub Actions runner's output, you should use the command echo "::error::Your error message" in your workflow's run step. This workflow command creates an error annotation that will appear in the logs, and

  you can optionally include file and line number information, such as echo "::error file=app.js,line=5::Error message".

  Example Simple Error.

  steps:

  -name: My Step

  run: echo "::error::Something went wrong in this step."

  Error with File and Line Information.

  steps:

  -name: My Step

  run: echo "::error file=src/main.py,line=25::Invalid syntax detected."

• Question 85:

  What is a valid scenario regarding environment secrets?

  A. configuring environment secrets for connecting to GitHub Enterprise Server
  B. configuring environment secrets to automatically pull from Azure Key Vault
  C. ensuring a job cannot access environment secrets until approval is obtained from a required reviewer
  D. ensuring only a specific step can access an environment secret
  A. configuring environment secrets for connecting to GitHub Enterprise Server

  ---

  Explanation

  GitHub secrets are used to securely store sensitive information like API keys, tokens, and passwords in repositories. When you store the sensitive information as a GitHub secret, you remove the need to hardcode the credential or key, and prevent exposure of it in your code or logs. The secret can then be used to authenticate services, manage credentials, and securely pass sensitive data in workflows. Note: For GitHub, you can use a personal access token, an OAuth app, a Secrets Manager secret, or a GitHub App connection to access the source provider. For GitHub Enterprise Server, you can use a personal access token, a Secrets Manager secret, or a GitHub App connection to access the source provider.

• Question 86:

  How should you print a debug message in your workflow?

  A. echo "::debug::Set variable myVariable to true"
  B. echo "Set variable MyVariable to true" >> $DEBUG_MESSAGE
  C. echo "::add-mask::Set variable myVariable to true"
  D. echo "debug_message=Set variable myVariable to true" >> andGITHUB_OUTPUT
  A. echo "::debug::Set variable myVariable to true"

  Explanation

  Example: Setting a debug message

  echo "::debug::Set the Octocat variable"

• Question 87:

  As a developer, how should you enable step debug logging for a workflow?

  A. Include the following code block in your workflow: env: ACTIONS_STEP_DEBUG: true
  B. Use the --actions-step-debug flag when calling the workflow.
  C. Include the following code block in your workflow: defaults: ACTIONS_STEP_DEBUG: true
  D. Set the ACTIONS_STEP_DEBUG secret or variable at the repository level to true.
  D. Set the ACTIONS_STEP_DEBUG secret or variable at the repository level to true.

  ---

  Explanation

  Enabling debug logging

  If the workflow logs do not provide enough detail to diagnose why a workflow, job, or step is not working as expected, you can enable additional debug logging.

  Enabling step debug logging

  Step debug logging increases the verbosity of a job's logs during and after a job's execution.

  1.To enable step debug logging, set the following secret or variable in the repository that contains the workflow: ACTIONS_STEP_DEBUG to true. If both the secret and variable are set, the value of the secret takes precedence over the

  variable.

  2.After setting the secret or variable, more debug events are shown in the step logs.

  A. packages: write
  B. repository: read
  C. actions: read
  D. contents: read
  E. issues: write
  A. packages: write

• Question 89:

  Which of the following contexts provides information about workflow metadata (like name and run ID)?

  A. job
  B. github
  C. env
  D. runner
  B. github

  A. uses: actions/cache@v3
  B. uses: actions/upload-artifact@v3
  C. uses: actions/store-data@v1
  D. uses: actions/archive@v2
  B. uses: actions/upload-artifact@v3

  ---

  Explanation

  The upload-artifact action saves files for later retrieval via the Actions UI or API.
