Which Azure service provides automated deployment as part of a CI/CD pipeline using Azure-native tools?

Azure Pipelines is the correct answer because it is a cloud service that provides automated build, test, and deployment capabilities, making it a core component for implementing CI/CD pipelines within Azure. It integrates with various source control systems and deployment targets. Azure DevTest Labs is incorrect because it focuses on creating environments for testing and development, not on automated CI/CD orchestration. Azure DevOps Services is a suite of services that includes Azure Pipelines, but Azure Pipelines is the specific component responsible for CI/CD. Azure Automation is used for automating tasks and processes, but it's not primarily designed for the comprehensive build and deployment orchestration of a CI/CD pipeline like Azure Pipelines.
