Refer to the exhibit.

transmission?

Exhibit F
Explanation:
When a host needs to reach a device on another subnet, the ARP cache entry will be that of the
Ethernet address of the local router (default gateway) for the physical MAC address. The
destination IP address will not change, and will be that of the remote host (HostB).
Nice Explanation Admin!!!!!!!!!!

U sure? Because the explanation was so wrong. D should be the correct answer. ARP is only used within its own subnet and won’t have any record for IP outside outside of your subnet. Try arp -a on your PC to confirm.

“D” is right
Host A knows host B is in another network so it will send the pings to its default gateway 192.168.6.1. Host A sends a broadcast frame asking the MAC address of 192.168.6.1. These information (IP and MAC address of the default gateway) is saved in its ARP cache for later use.

Sure but the question says that the process happens after a ping was done so Host A takes the gateway MAC address as the destination with the IP address 192.168.4.7
