Microsoft DevOps Engineer Expert AZ-400 Practice Question

Your company's operations team uses an Azure Monitor action group that pages the on-call engineer whenever an alert is fired. You are asked to surface an alert each time any run of the multi-stage YAML pipelines in your Azure DevOps project ends in a failed state. You must meet the following requirements:

  • Do not modify any existing pipeline YAML files.
  • Configure and manage the alert entirely from the Azure portal.
  • Re-use the existing action group without additional code.

Which approach should you implement?

  • Create an Azure DevOps notification subscription for the "Build completed" event and set the delivery channels to email and Microsoft Teams for the operations group.

  • Enable diagnostic settings for the Azure DevOps organization to stream audit logs to a Log Analytics workspace, then create a Log Analytics query alert rule that filters BuildCompleted events where Result equals "failed" and assigns the existing action group.

  • Add a task to every pipeline that calls the Azure Monitor REST API to emit a custom metric on failure, and configure a metric alert on that custom metric.

  • Configure continuous export of pipeline run data to Azure Data Explorer and set up a scheduled Kusto query alert that detects failed runs and calls the action group.
