Which protocol is used to discover the destination address needed to be added to an Ethernet frame?

  • ARP
  • DNS
  • DHCP
  • HTTP

Explanation: In the data link layer, a frame header is added. The frame header includes the source and destination MAC addresses. In order to find the MAC address of the destination host, the sending host uses the Address Resolution Protocol (ARP). If the destination host is not on the same LAN, the MAC address of the default gateway is used as the destination MAC address in the frame header.
