Question
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.
