Which protocol uses ports 67 and 68 for automatically assigning IP addresses and network settings?

• A. Hypertext Transfer Protocol (HTTP)
• B. Network Basic Input/Output System (NetBIOS)
• C. Dynamic Host Configuration Protocol (DHCP)
• D. Internet Message Access Protocol (IMAP)

Answer: (C)

The Dynamic Host Configuration Protocol (DHCP) is designed to automatically assign IP addresses and other network configuration settings to devices on a network. It operates using a client-server model, where the DHCP server assigns IP addresses to DHCP clients. Ports 67 and 68 are specifically associated with DHCP: port 67 is used by the server to listen for client requests, while port 68 is used by the client to send requests and receive information from the server. This functionality enables devices to configure their network settings without manual intervention, which is essential in dynamic and large network environments. Understandably, the other protocols mentioned have different purposes. HTTP is utilized primarily for transferring web pages, NetBIOS deals with network communications in a Windows environment, and IMAP is used for retrieving email from a mail server, none of which relate to the automatic assignment of IP addresses and network settings.
