A client packet is received by a server. The packet has a destination port number of 80. What service is the client requesting?

  • DHCP
  • SMTP
  • DNS
  • HTTP

Explanation: The transport layer uses port numbers to identify specific applications and services. According to the well-known port assignments, port 80 is reserved for Hypertext Transfer Protocol (HTTP) web services. When a server receives a packet with port 80 as the destination, it identifies the request as a client seeking to access web content, such as HTML pages. This standardized numbering allows the server to simultaneously handle multiple services, distinguishing web traffic from other requests like DNS (port 53) or SMTP (port 25).
