Of the following choices, which industry-standard protocol is used by computer networks to automatically assign IP addresses and related configuration information to network nodes and devices?
Dynamic Host Configuration Protocol (DHCP) is a client-server protocol that automatically assigns IP addresses, subnet masks, default gateways, and other parameters to devices joining an IP network.
Why the other options are incorrect:
Domain Name System (DNS) translates human-readable host names into IP addresses and vice versa; it does not assign addresses.
Address Resolution Protocol (ARP) resolves a known IPv4 address to its corresponding MAC (hardware) address on the local network segment.
Reverse Address Resolution Protocol (RARP) performs the opposite mapping (MAC → IP) but is now obsolete and has largely been replaced by DHCP.
Thus, DHCP is the only listed protocol whose primary purpose is automatic IP address assignment.
