AZ-400 Application Dashboard Practice Question

You have an Azure DevOps pipeline that deploys a web app to Azure App Service. You want to capture deployment frequency and change failure rate as metrics in Application Insights. Which built-in analytics view should you use?

⚠ Common exam trap

Candidates may assume that 'Deployment Frequency' is a built-in Application Insights view because it appears in the Azure DevOps UI. However, it is a report within Azure DevOps Analytics, not a view in Application Insights. The question specifically asks for an Application Insights built-in analytics view.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Application Dashboard

The Application Dashboard in Application Insights is a built-in analytics view that provides a customizable overview of your application's metrics. While it does not natively display deployment frequency or change failure rate, you can configure it with metric tiles to show these values if telemetry is properly instrumented. Option A is incorrect because 'Deployment Frequency' is a report in Azure DevOps Analytics, not a built-in view in Application Insights.
