Why each option
DHCP (Dynamic Host Configuration Protocol) is the protocol responsible for automatically assigning IP addresses and network configuration parameters to hosts on a network.
FTP (File Transfer Protocol) is an application-layer protocol for transferring files between a client and server and has no role in IP address assignment.
ATAPI (AT Attachment Packet Interface) is a hardware interface standard used to connect optical drives and storage devices to a motherboard, not a network protocol.
DNS (Domain Name System) resolves human-readable hostnames to IP addresses for routing purposes, but it does not assign IP addresses to hosts.
DHCP uses a four-step DORA process (Discover, Offer, Request, Acknowledge) where a client broadcasts a request and a DHCP server responds with an available IP address, subnet mask, default gateway, and DNS server settings. This eliminates the need for manual static IP configuration on each host.
