Your team uses Azure Pipelines to deploy applications. You must notify all team members in Microsoft Teams when a build or release fails, while minimizing development effort. What should you do?

The correct answer is to install the Azure Pipelines app for Teams and configure a subscription. The Azure Pipelines app is specifically designed for this purpose, offering direct integration with Microsoft Teams to provide notifications for build and release events, including failures. This is the most straightforward and least effort-intensive solution. Installing the Azure Boards app for Teams would provide notifications related to work items, not build or release failures. Using Azure Automation or an Azure Function to connect to the Azure DevOps REST API would be significantly more complex and require custom development, which goes against the requirement to minimize development effort. While these methods are technically possible, they are not the most efficient or recommended approach for this specific scenario.
