When a computer is pinging another computer for the first time, what type of message does it place on the network to determine the MAC address of the other device?

  • an ICMP ping
  • an ARP request
  • an RFI (Request for Information) message
  • a multicast to any Layer 3 devices that are connected to the local network

Explanation: An ARP request is used to determine any unknown MAC address when the destination IP address is known. In an IPv4-based network, this request is sent as a Layer 2 broadcast.
