What is one function of the ARP protocol?

  • obtaining an IPv4 address automatically
  • mapping a domain name to its IP address
  • resolving an IPv4 address to a MAC address
  • maintaining a table of domain names with their resolved IP addresses

Explanation: The two main functions of the ARP protocol are to resolve an IPv4 address to a MAC address and to maintain an ARP table, which lists the resolved pairs of IPv4 address and MAC address. A device automatically obtains an IP address through DHCP. The functions of DNS include resolving (or mapping) a domain name with its IP address and maintaining a table for the domain name/IP pairs.
