Why each option
This question asks to identify the network protocol responsible for resolving an IP address to its corresponding MAC address.
DNS (Domain Name System) translates human-readable domain names into IP addresses, not IP to MAC addresses.
The Address Resolution Protocol (ARP) is used to map an Internet Protocol (IP) address to a physical machine address (MAC address) on a local network. This translation allows devices to communicate within the same broadcast domain.
NAT (Network Address Translation) translates private IP addresses to public IP addresses (and vice-versa).
DHCP (Dynamic Host Configuration Protocol) assigns IP addresses and other network configuration parameters to devices on a network.
Concept tested: Network protocol functions (ARP, DNS, NAT, DHCP)
