AZ-900 Describe Azure architecture and services Practice Question
Which Azure service provides automated build, test, and deployment pipelines for applications using a fully managed service?
⚠ Common exam trap
Watch out — candidates often confuse Azure Container Registry (a storage service) or Azure Logic Apps (an integration service) with a CI/CD pipeline, but only Azure Pipelines provides the automated build, test, and deployment lifecycle as a fully managed service.

Correct answer & explanation
✓
Azure Pipelines
Azure Pipelines is a fully managed continuous integration and continuous delivery (CI/CD) service that automates the build, test, and deployment of applications to any target. It integrates with GitHub, Azure Repos, and other version control systems to trigger pipelines on code changes, and supports multi-stage YAML-based definitions for complex workflows.
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 Container Registry
Why it's wrong here
Azure Container Registry is a private registry for storing and managing Docker container images and other OCI artifacts. It does not execute build or deployment jobs; rather, it can serve as an artifact repository that a CI/CD pipeline pushes to and pulls from during release. Leaving compilation, unit testing, and release gates to Container Registry would be impossible because it lacks the scheduling and task execution engine that Azure Pipelines provides.
- ✓
Azure Pipelines
Why this is correct
Azure Pipelines is a cloud-hosted CI/CD service within Azure DevOps that automatically builds, tests, and deploys code to any platform or cloud. It supports YAML-based multi-stage pipelines, containers, and integration with GitHub and other repositories. For the vending machine scenario—where developers need a repeatable path to push updates—Pipelines is the correct managed service that executes the build, test, and deployment orchestration.
- ✗
Azure Logic Apps
Why it's wrong here
Azure Logic Apps is a low-code/integration platform for automating business workflows across hundreds of services, such as Office 365, SharePoint, and custom APIs. Its triggers and actions are optimized for business process orchestration (e.g., send an email when an order arrives) rather than for compiling source code and coordinating multi-stage releases. Although Logic Apps can connect to DevOps APIs, it is not designed to run the build and deployment pipeline itself, so Azure Pipelines remains the correct CI/CD service.
- ✗
Azure App Configuration
Why it's wrong here
Azure App Configuration is a service for centrally managing application settings and feature flags, not for orchestrating software release workflows. While an app might read operational configuration from App Configuration, the building, testing, and deployment stages of a CI/CD solution are executed by Azure Pipelines. Admins might confuse 'configuration' of builds with app configuration, but the two solve different problems and cannot replace a pipeline service.
