AZ-900 Describe Azure architecture and services Practice Question
Which Azure service enables automated build and release pipelines triggered by code changes in a Git repository?
⚠ Common exam trap
It's easy for candidates to confuse Azure Pipelines (a CI/CD service) with Azure Logic Apps (an integration workflow service) because both involve 'automation' and 'triggers,' but Logic Apps cannot build or deploy code from Git repositories.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Pipelines
Azure Pipelines is the correct service because it is specifically designed for continuous integration and continuous delivery (CI/CD), enabling automated build and test workflows that trigger on code changes in a Git repository. It supports multiple Git providers (e.g., GitHub, Azure Repos, Bitbucket) and can deploy to any target, making it the native DevOps solution for automating pipelines from source control commits.
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 Logic Apps
Why it's wrong here
Azure Logic Apps is a cloud service for orchestrating business workflows and integrating applications, data, and services across enterprises. It excels at connecting disparate systems through hundreds of connectors, but it is not designed for compiling source code, running unit tests, or packaging artifacts. While Logic Apps can trigger on repository events, it lacks built-in build agents, test runners, and deployment gates that are core to a CI/CD pipeline. Therefore, it is incorrect for automating the build-and-deploy lifecycle of application code.
- ✓
Azure Pipelines
Why this is correct
Azure Pipelines is the CI/CD service within Azure DevOps that automatically builds, tests, and deploys code whenever changes are pushed to a connected Git repository. It provides configurable YAML or classic build definitions, supports multiple platforms and languages, and runs jobs on Microsoft-hosted or self-hosted agents. Pipelines can include stages for building, testing, and releasing to multiple environments, making it the correct choice for automating software delivery. Its purpose is exactly the continuous integration and continuous delivery workflow described in the question.
- ✗
Azure Resource Manager templates
Why it's wrong here
Azure Resource Manager (ARM) templates are declarative JSON files that define the infrastructure and configuration of Azure resources, such as virtual machines, networks, and storage accounts. They enable infrastructure-as-code by allowing you to provision and manage resources consistently and repeatedly, but they do not build, test, or deploy application code. ARM templates are used during the deployment phase to create or update Azure resources, not to run the software compilation or testing steps. Because the question focuses on the CI/CD automation of code changes, ARM templates are not the appropriate tool.
- ✗
Azure Automation runbooks
Why it's wrong here
Azure Automation runbooks are scripts (PowerShell, Python, or graphical) that perform operational and administrative tasks, such as patching VMs, managing alerts, or orchestrating routine maintenance. They run in the Azure Automation service and are triggered by schedules or webhooks, but they are not optimized for the build-test-deploy cycle of application code. While a runbook could theoretically invoke a build command, it lacks the integrated source control triggers, artifact management, and release pipelines that Azure Pipelines provides. Thus, runbooks are intended for IT operations automation, not software CI/CD.
