You must test an ASP.NET web app using Application Insights to ensure it is available and responsive from multiple global locations at regular intervals, and alert support if it’s unresponsive. Which two test types are appropriate?

URL ping tests are appropriate because they check the availability of a URL from multiple global locations at regular intervals, meeting the requirement to test availability and responsiveness. Multi-step web tests are also appropriate as they allow for a sequence of URL requests and can simulate more complex user scenarios, ensuring the application's functionality is responsive beyond a single page load. Integration tests focus on interactions between different modules or services, not global availability. Unit tests verify individual components in isolation. Load tests assess performance under heavy traffic, which is different from regular availability monitoring.
