该 集中式共享仓库模型 将 Git 的使用从混乱的点对点交换转变为结构化的中心辐射拓扑。通过建立一个 “单一事实来源”，这种集中式协作工作流旨在解决实时追踪数十个不同开发者的仓库所带来的混乱，确保像 my-git-repo 和 marys-repo 这样的项目拥有一个明确的同步点。
1. 核心概念
- 集中式工作流程： 一种结构化环境，开发者将代码推送到专用存储仓库中，并从其中拉取更新，而不是在本地仓库之间直接共享。
- 通信枢纽： 团队通常使用 Bitbucket，一个分布式版本控制系统（DVCS）托管服务，可轻松创建 Git 仓库并作为主要协调中心。
- 集成者： 一个特殊角色，除了担任普通开发者外，还负责管理私有环境与公开仓库之间的变更流动。

QUESTION 1
Navigate your web browser to Bitbucket.org and sign up for a free account.
Task Completed
Task Not Completed
✅ Correct!
Excellent! Setting up a Bitbucket account is the first step toward professional centralized collaboration.❌ Incorrect
Please navigate to Bitbucket.org and sign up to proceed with the lab exercises.QUESTION 2
Add the following to the end of style.css:
h1, h2 {
font-size: 2em;
color: #333;
}
a:link, a:visited {
color: #007bff;
}
I have added the CSS code correctly.
I encountered an error.
✅ Correct!
CSS updated. This change will be used to demonstrate the synchronization process later.❌ Incorrect
Ensure the syntax matches the provided code block exactly in your local style.css file.QUESTION 3
What is the primary purpose of a centralized collaboration workflow?
To allow developers to share files over email.
To solve the chaos of tracking multiple developers' repositories in real-time.
To prevent developers from keeping local copies of the project.
To replace Git with a centralized SVN server.
✅ Correct!
The centralized model creates a hub-and-spoke topology where one repository acts as the 'Single Source of Truth'.❌ Incorrect
Review the definition of the centralized collaboration workflow; it is designed to organize team synchronization.QUESTION 4
True or False: In a centralized model, developers no longer maintain a full copy of the project history.
True
False
✅ Correct!
Correct! Git is a DVCS; every developer still has a full local repository, but they use the central one for synchronization.❌ Incorrect
Even in a centralized model, Git remains a Distributed Version Control System (DVCS).QUESTION 5
Who is responsible for managing the flow of changes between private environments and the public repository?
The Junior Developer
The Bitbucket Admin
The Integrator
The ISP Provider
✅ Correct!
The Integrator acts as an ordinary developer but with additional responsibilities for merging and publishing.❌ Incorrect
The term 'Integrator' specifically defines this role in the workflow hierarchy.Establishing the Communication Hub
Centralizing a Peer-to-Peer Team
Your team is currently sharing commits by pulling directly from each other's laptops (e.g., John pulls from Mary). This is causing issues when Mary is offline. You decide to implement a centralized model using Bitbucket as the hub.
Q
How does the role of the 'Integrator' facilitate this new workflow for John and Mary?
Solution:
The integrator ensures that changes from 'Mary's Repo' and 'John's Repo' are properly synced to the 'Central Repo'. Instead of pulling from each other, they both interact with the Integrator's managed public repo to ensure a linear, stable history.

Q
What Git command must be executed by every team member to identify their contributions in this shared environment?
Solution:
Every developer must run 'git config --global user.email [email protected]' to ensure their commits are correctly attributed in the central project history.
