What is a characteristic of ARP messages?

• ARP messages have a type field of 0x805.
• ARP messages are encapsulated within an IPv4 header.
• ARP replies are unicast.
• ARP requests are broadcasts, and they are flooded out all ports by the switch.

Explique: Because ARP requests are broadcasts, they are flooded out all ports by the switch except the receiving port. Only the device that originally sent the ARP request will receive the unicast ARP reply. ARP messages have a type field of 0x806. ARP messages are encapsulated directly within an Ethernet frame. There is no IPv4 header.
