What defines a Web Application in the context of Dynatrace?

A Web Application in the context of Dynatrace is defined by its ability to deliver a user interface that operates within a JavaScript-enabled browser. This characteristic is essential because modern web applications utilize JavaScript to enhance interactivity and provide a dynamic user experience. The reliance on JavaScript is a key aspect of how web applications function, as it allows for the creation of responsive and engaging user interfaces that operate seamlessly in web browsers.

In contrast, hosting a web application on a dedicated server, installation on mobile devices only, or requiring root access for configuration does not inherently define what a web application is. Web applications can be hosted on various environments, including cloud services, shared servers, or dedicated hardware, and they are not restricted to mobile platforms alone. Additionally, the requirement of root access is not a defining feature of a web application, as many can be configured and managed without needing elevated permissions.

Thus, option B accurately captures the essence of what constitutes a web application in the context of Dynatrace, focusing on the user interface and its operation within web browsers.
