The standard port for RDP (Remote Desktop Protocol) is?

TCP/161
UDP/514
TCP/3389
TCP/636

The correct answer is: TCP/3389

The standard port for Remote Desktop Protocol (RDP) is TCP/3389 because this port is specifically allocated for RDP communications, which is primarily used for remote management and access to Windows-based systems. RDP allows users to connect to another computer over a network connection and provides a graphical user interface for interaction. Using TCP/3389 ensures a reliable connection, as TCP (Transmission Control Protocol) is designed for connection-oriented communication, which is essential for maintaining the stability and integrity of remote sessions. The choice of this port is widely recognized in networking standards and is built into the Windows operating system, making it the default for RDP. Other port options listed, such as TCP/161, UDP/514, and TCP/636, serve different protocols. For instance, TCP/161 is used for SNMP (Simple Network Management Protocol), UDP/514 is associated with syslog (for log forwarding), and TCP/636 is designated for LDAPS (LDAP over SSL). Each of these ports is tailored for specific functionalities, which distinguishes them from the purpose of RDP. Thus, TCP/3389 is the correct answer for remote desktop access.
