Which of the following correctly identifies the association of port 67?

Port 67 is primarily associated with the DHCP server role. The Dynamic Host Configuration Protocol (DHCP) uses this port for communication to provide IP addresses and other network configuration details to DHCP clients within a network. When a client wants to receive a network configuration, it sends a DHCP Discover packet to the server. The server responds with an offer, which is sent from port 67, thus facilitating the configuration of the client device.

In the context of the other options:

• A DHCP client operates on port 68, as it listens for messages from the server that are sent from port 67.

• TFTP (Trivial File Transfer Protocol) uses port 69 for file transfers, which is unrelated to DHCP.

• DNS (Domain Name System) typically operates over port 53, making it distinct from the functions of DHCP.

Understanding the specific roles and associated ports helps clarify network connectivity and service functioning within the realm of networking.
