RDP, or Remote Desktop Protocol, is primarily designed to facilitate remote desktop sharing. This technology enables users to connect to and control a computer over a network connection, allowing them to access the desktop interface of that remote system as if they were sitting right in front of it. Through RDP, a user can run applications, transfer files, and manage the operating system of the remote machine, providing a seamless experience for tasks that require a graphical user interface.

The other options focus on different aspects of network functionality. File sharing across networks entails the transfer of files between devices without necessarily providing access to the entire desktop environment. Log centralization refers to collecting and managing logs from various systems in a single location, which enhances monitoring and auditing but is not related to desktop access. Voice over IP (VoIP) setup deals with transmitting voice calls over the internet, focusing on audio communication rather than visual desktop interfacing. Thus, while these options serve valuable purposes in networking, they do not relate to the primary function of RDP, which is clearly centered around remote desktop sharing.
