Why each option
Remote Desktop Protocol (RDP) utilizes a specific TCP port by default for establishing remote connections to servers.
Port 23 is used by Telnet, an unencrypted terminal emulation protocol that is generally considered insecure for modern use.
Port 902 is commonly associated with VMware ESXi hosts for client connections or used by VMware vCenter Server for certain management traffic.
Port 1677 is not a standard or commonly recognized default port for any major IT service or protocol.
Remote Desktop Protocol (RDP) clients connect to RDP servers, such as those running on Windows, using TCP port 3389 by default. This port facilitates the transmission of graphical interface data and user input between the client and server for remote management.
