最新的 GitHub Administrator GH-200 免費考試真題 (Q119-Q124):

問題 #119
What are the advantages of using a matrix strategy in a job definition? (Choose two.)

A. It can run up to 512 jobs per workflow run.
B. It can decrease the costs for running multiple combinations of programming language/operating systems.
C. It can test code in multiple versions of a programming language.
D. It can test code in multiple operating systems.

答案：C,D

解題說明：
A matrix strategy allows you to define different versions of a programming language (or any other environment setting) and run tests on each version simultaneously. This is particularly useful for testing code compatibility across different versions of a language.
A matrix strategy can also be used to test code on multiple operating systems (e.g., Windows, macOS, Linux) by defining these operating systems as matrix variables. This enables cross-platform testing within the same workflow.

問題 #120
As a developer, you need to leverage Redis in your workflow. What is the best way to use Redis on a self-hosted Linux runner without affecting future workflow runs?

A. Specify container: and services: in your job definition to leverage a Redis service container.
B. Add a run step to your workflow, which dynamically installs and configures Redis as part of your job.
C. Install Redis on the hosted runner image and place it in a runner group. Specify label: in your job to target the runner group.
D. Set up Redis on a separate machine and reference that instance from your job.

答案：A

解題說明：
Creating Redis service containers
You can use service containers to create a Redis client in your workflow. You can create a Redis service for jobs that run in containers or directly on the runner machine.
Configuring the runner job
The example uses the ubuntu-latest GitHub-hosted runner as the Docker host.
The workflow configures a service container with the label redis.
jobs:
# Label of the runner job
runner-job:
# You must use a Linux environment when using service containers or container jobs runs-on: ubuntu-latest
# Service containers to run with `runner-job`
services:
# Label used to access the service container
redis:
# Docker Hub image
image: redis
# Set health checks to wait until redis has started
options: >-
--health-cmd "redis-cli ping"
--health-interval 10s
--health-timeout 5s
--health-retries 5
ports:
# Maps port 6379 on service container to the host
- 6379:6379

問題 #121
How should you install the bats NPM package in your workflow?
A)
B)
C)
D)

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

答案：C

解題說明：
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.

問題 #122
Scheduled workflows run on the:

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

答案：B

解題說明：
Scheduled workflows run on the latest commit on the default branch.
Note: The default branch is also the initial branch that Git checks out locally when someone clones the repository. Unless you specify a different branch, the default branch in a repository is the base branch for new pull requests and code commits.

問題 #123
As a developer, which workflow steps should you perform to publish an image to the GitHub Container Registry? (Each correct answer represents part of the solution. Choose three).

A. Push the image to the GitHub Container Registry.
B. Pull the image from the GitHub Container Registry.
C. Use the actions/setup-docker action.
D. Build the container image.
E. Authenticate to the GitHub Container Registry.

答案：A,D,E

解題說明：
Publishing Docker images
The below workflow checks out the GitHub repository, uses the login-action to log in to the registry [B], and then uses the build-push-action action to: build a Docker image based on your repository's Dockerfile [E]; push the image to Docker Hub [A], and apply a tag to the image.
Note:
# This workflow uses actions that are not certified by GitHub.
# They are provided by a third-party and are governed by
# separate terms of service, privacy policy, and support
# documentation.
# GitHub recommends pinning actions to a commit SHA.
# To get a newer version, you will need to update the SHA.
# You can also reference a tag or branch, but the action may change without warning.
