Explanation Explanation: For the initial communication, Host A will send a broadcast ARP (all F's) to determine the correct address to use to reach the destination. ARP sends an Ethernet frame called an ARP request to every host on the shared link-layer legmen. The Ethernet header includes the source host MAC address and a destination address of all Fs representing a broadcast frame. The ARP request contains the sender's MAC and IP address and the target (destination) IP address. The target's MAC address is set to all 0s.
