AZ-900 Describe Azure architecture and services Practice Question
Which Azure service provides code repository hosting with features like pull requests, code review, and branch protection?
⚠ Common exam trap
Test-takers frequently confuse Azure Repos with Azure Pipelines or Azure Boards because all three are part of Azure DevOps, but only Azure Repos provides the actual code repository hosting with pull request and branch protection features.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Repos
Azure Repos is the correct answer because it provides Git-based code repository hosting with full support for pull requests, code review workflows, and branch protection policies. These features enable teams to collaborate on code changes, enforce quality gates, and prevent direct pushes to critical branches.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Azure Artifacts
Why it's wrong here
Azure Artifacts is a package management service that creates and manages feeds for hosting binary packages such as NuGet, npm, and Maven artifacts. It stores compiled or versioned packages for consumption by builds and deployments, distinct from the raw source code itself. Thus, Azure Artifacts is incorrect because it handles dependency distribution, not source code versioning.
- ✓
Azure Repos
Why this is correct
Azure Repos is the source control service within Azure DevOps. It provides both Git and Team Foundation Version Control (TFVC) repositories, enabling teams to host code, manage branches, and collaborate through pull requests. With features like branch policies, required reviewers, and code search, Azure Repos directly fulfills the role of storing and managing source code. This is why it is the correct answer when the question asks which service provides version control.
- ✗
Azure Pipelines
Why it's wrong here
Azure Pipelines is a continuous integration and continuous delivery (CI/CD) service that automates building, testing, and deploying applications. It reads source code from a repository but does not persist or manage that code; instead, it consumes the code to execute workflows. Therefore, while Pipelines integrates with Azure Repos, it is not the service responsible for hosting source code, making it an incorrect choice.
- ✗
Azure Boards
Why it's wrong here
Azure Boards is a work management and project planning tool that provides backlogs, boards, and sprint tracking. It organizes and tracks tasks, bugs, features, and epics, connecting them to commits and builds, but it does not store source code. Because Azure Boards addresses project tracking rather than version control, it does not meet the requirement for source code hosting.
