Which of the following statements about the functions and packet encapsulation of the ARP protocol is true?
ARP packets are encapsulated over Ethernet. ARP (Address Resolution Protocol) is used for mapping IP addresses to MAC addresses on a local network and operates at the data link layer (Layer 2) of the OSI model. When an ARP request is made on an Ethernet network, the ARP packet is encapsulated within an Ethernet frame, which includes the source and destination MAC addresses. This allows the packet to be transmitted over the Ethernet network to reach the intended recipient.
Option D: When used on Ethernet networks, ARP packets are encapsulated within Ethernet frames with a specific EtherType value indicating they contain ARP data. This allows them to be transmitted and received by devices on the network.
Resposta correta. (D) Os pacotes ARP são encapsulados em um quadro Ethernet, que inclui o endereço MAC do dispositivo de origem e do dispositivo de destino. O quadro Ethernet é então transmitido pela rede para o dispositivo de destino.
