DHCP Protocol Transport Type

D.

The correct answer is D. UDP ports 67 and 68.

The Dynamic Host Configuration Protocol (DHCP) is a network protocol used to dynamically allocate IP addresses and other network configuration parameters to devices on a network. DHCP uses User Datagram Protocol (UDP) as its transport protocol, and it uses UDP ports 67 and 68 for communication between DHCP clients and servers.

DHCP works by having a DHCP server on the network that assigns IP addresses and other configuration parameters to DHCP clients. When a DHCP client boots up or connects to the network, it sends a broadcast message on the network to discover available DHCP servers. DHCP servers respond to the client's request, offering an IP address and other configuration parameters.

The DHCP client then selects one of the offered configurations, and requests the IP address and other parameters from the chosen DHCP server. The DHCP server responds with a DHCP offer, including the IP address and other configuration parameters, and the client accepts the offer and begins using the assigned IP address and configuration.

The communication between the DHCP client and server takes place using UDP packets, with the client sending requests to the server on UDP port 68, and the server responding on UDP port 67.

Therefore, the correct answer is D, UDP ports 67 and 68.
