Which model allows end users to utilize virtual desktops without relying on local machine resources?

The correct answer is the VDI Remote Virtual Desktop Model. This model enables end users to access virtual desktops hosted on a remote server rather than depending on their local machine's resources. By utilizing server-based computing, users can run applications and perform tasks that may exceed the capabilities of their local devices.

In this model, the heavy lifting is done on the server side, allowing for more powerful processing, storage, and memory than might be available on a user's device. This setup enhances flexibility and scalability, enabling users to log in from various devices and access a consistent desktop experience.

The other models mentioned do not emphasize this aspect of remote resource utilization as effectively. For instance, the centralized model may imply a central management of desktops but does not fully convey the remote access angle. The hosted model can refer to the arrangement of the virtual desktop infrastructure being hosted elsewhere but lacks specificity about the remote user experience. Lastly, the local model focuses on utilizing local machine resources, which is contrary to the goal of freeing users from dependence on their device capabilities.
