What property of ARP causes the NICs receiving an ARP request to pass the data portion of the Ethernet frame to the ARP process?

  • The type field 0x806 appears in the header of the Ethernet frame.
  • The destination MAC address FF-FF-FF-FF-FF-FF appears in the header of the Ethernet frame.
  • Entries in an ARP table are time-stamped and are purged after the timeout expires.
  • ARP replies are broadcast on the network when a host receives an ARP request.
Explanation & Hint:

The property of ARP (Address Resolution Protocol) that causes the NICs receiving an ARP request to pass the data portion of the Ethernet frame to the ARP process is:

“The type field 0x806 appears in the header of the Ethernet frame.”
The Ethernet frame type field indicates the protocol being used within the data portion of the frame. In the case of ARP, the type field is set to 0x806, which signifies that the frame contains ARP information. When a NIC receives an Ethernet frame with this type field, it recognizes that the frame contains ARP data and forwards it to the ARP process to handle the ARP request. This allows the NIC to pass the ARP request to the appropriate software layer for processing and resolution of IP addresses to MAC addresses.
