You have a Microsoft ASP.NET Core web app in Azure that is accessed worldwide. You need to run a URL ping test once every five minutes and create an alert when the web app is unavailable from specific Azure regions. The solution must minimize development time. What should you do?

A. Create an Azure Application Insights availability test and alert

B. Create an Azure Service Health alert for the specific regions.

C. Create an Azure Monitor Availability metric and alert

D. Write an Azure function and deploy the function to the specific regions.

A. Create an Azure Application Insights availability test and alert

There are three types of Application Insights availability tests:

URL ping test: a simple test that you can create in the Azure portal.
Multi-step web test
Custom Track Availability Tests

Note: After you've deployed your web app/website, you can set up recurring tests to monitor availability and responsiveness. Azure Application Insights sends web requests to your application at regular intervals from points around the world. It can alert you if your application isn't responding, or if it responds too slowly.
You can set up availability tests for any HTTP or HTTPS endpoint that is accessible from the public internet. You don't have to make any changes to the website you're testing. In fact, it doesn't even have to be a site you own. You can test the availability of a REST API that your service depends on.
