A server is running HTTP, SMTP and DHCP. Which of the following best explains how the server is able to handle all three services over the same connection? The server has separate buffer areas for each application and forwards all data to each service. If the data does not apply to that application, it is discarded. The server processes each packet one at a time and forwards the data to the application that indicates that it is waiting for a transmission to arrive. The data is discarded if it does not apply to that application. The server uses the destination port number in the TCP/UDP header to identify the service. The data is forwarded to the service identified by the port number. The server uses separate three-way handshake connections to control the flow of the data and relates the service to the proper connection. This relationship allows the server to pass the data to the proper service.
