Answer: D

Explanation:

For web pages, Application Insights JavaScript SDK automatically collects AJAX calls as dependencies.

Note: Some of the things you can track or collect are:

What are the most popular webpages in your application, at what time of day and where is that traffic coming from?

Dependency rates or response times and failure rates to find out if there’s an external service that’s causing performance issues on your app, maybe a user is using a portal to get through to your application and there are response time issues going through there for instance.

Exceptions for both server and browser information, as well as page views and load performance from the end users’ side.
