質問 # 74
As a DevOps engineer, you are developing workflows to build an application. You have a requirement to create the build targeting multiple node versions. Which code block should you use to define the workflow?
正解：B
解説：
The correct GitHub Actions syntax for running a job across multiple Node.js versions is strategy.
matrix. The matrix values are referenced at runtime through the matrix context, so node-version: ${{ matrix.node-ver }} is correct. Option A defines the matrix correctly but references it incorrectly through strategy.node-ver; matrix values are not accessed through the strategy context. Option C uses matrix-strategy, which is not a valid GitHub Actions workflow key. Option D reverses the structure by putting strategy under matrix, which is invalid. This question tests matrix strategy syntax, dynamic job configuration, and using matrix values as inputs to actions such as actions/setup-node. GitHub defines jobs. < job_id > .strategy.matrix as the proper matrix mechanism.
質問 # 75
You need to create new workflows to deploy to an unfamiliar cloud provider. What is the fastest and safest way to begin?
正解：D
解説：
Searching the GitHub Marketplace for verified actions published by the cloud provider is the quickest and safest approach. Many cloud providers offer verified GitHub Actions that are maintained and optimized to interact with their services. These actions typically come with the correct configurations and best practices, allowing you to get started quickly without reinventing the wheel.
Note: About GitHub Marketplace for apps
GitHub Marketplace where you can share your apps with everyone.
GitHub Marketplace connects you to developers who want to extend and improve their GitHub workflows. You can list free and paid tools for developers to use in GitHub Marketplace. GitHub Marketplace offers developers two types of tools: GitHub Actions and Apps, and each tool requires different steps for adding it to GitHub Marketplace.
GitHub Actions
Anyone can publish an action in GitHub Marketplace. GitHub verifies some partner organizations and these are shown as verified creators.

質問 # 76
You need to perform a task that requires running a custom script in a GitHub Actions workflow. The script must run within the workflow environment without requiring an external container or prebuilt image.
What should you use?
正解：C
解説：
The simplest correct choice is a run step. A run step executes shell commands or scripts directly on the runner inside the current workflow job environment. It does not require packaging a JavaScript action, building a Docker container, publishing an image, or creating reusable action metadata. A JavaScript action is appropriate when you are building a reusable Node.js-based action. A Docker container action is useful when the execution environment must be packaged with dependencies, but it adds container overhead. A composite action is useful for reusable sequences of steps, but the question asks only for running a custom script inside the workflow environment. GitHub workflow syntax shows run steps as the native way to execute commands inside a job.
質問 # 77
You need to store an API key in a GitHub repository. The solution must ensure that the key remains secure and can be used in a GitHub Actions workflow. What should you do?
正解：A
解説：
To use a specific API key in your GitHub Actions workflow, you can store it as a Repository Secret and reference it using the secrets context in your YAML file. This ensures the key is encrypted and masked in your workflow logs.
1. Store the API Key as a Secret
Navigate to your repository on GitHub.com.
Click Settings > Secrets and variables > Actions.
Select the Secrets tab and click New repository secret.
In the Name field, enter a descriptive identifier (e.g., MY_API_KEY).
Rules: Use only alphanumeric characters or underscores; cannot start with a number or GITHUB_.
In the Secret field, paste your API key value and click Add secret.
2. Reference the Secret in your YAML File
In your .github/workflows/your-workflow.yml file, access the secret using the syntax
${{ secrets.NAME_OF_SECRET }}. It is a best practice to map it to an environment variable within a specific step rather than echoing it directly.
Example Workflow in yaml:
name: Use API Key Example
on: [push]
jobs:
my-job:
runs-on: ubuntu-latest
steps:
- name: Run script with API Key
# Map the secret to an environment variable for the runner
env:
API_KEY: ${{ secrets.MY_API_KEY }}
run: |
# Use the environment variable in your commands
curl -H "Authorization: Bearer $API_KEY" https://api.example.com

質問 # 78
In which scenarios could the GITHUB_TOKEN be used? (Choose two.)
正解：C、F
解説：
The GITHUB_TOKEN is automatically provided by GitHub in workflows and can be used to authenticate API requests to GitHub, including publishing packages to GitHub Packages.
The GITHUB_TOKEN is also used to authenticate API requests for actions like creating issues, commenting, or interacting with pull requests within the same repository.
