question 32
what property of arp forces all ethernet nics to process an arp request?
arp replies are broadcast on the network when a host receives an arp request.
the type field 0x806 appears in the header of the ethernet frame.
the source mac address 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.

Explanation:

ARP requests are broadcast messages. The destination MAC address of a broadcast ARP request is the all - ones MAC address (FF - FF - FF - FF - FF - FF). When an Ethernet NIC sees this destination MAC address in the frame header, it processes the ARP request. The other options do not force all NICs to process the request. The type field (0x806) indicates it's an ARP packet but doesn't force processing alone. The source MAC address is just the sender's address and is not relevant for forcing processing. ARP replies are not what force initial processing of requests.

Answer:

The destination MAC address FF - FF - FF - FF - FF - FF appears in the header of the Ethernet frame.
