   A host has IP address 192.168.1.10 with subnet mask 255.255.255.0. It wants to send a packet to 192.168.2.20. How does the host determine that the destination is on a remote network?

   • AIt checks the destination IP address against the default gateway's IP address.
   • BIt compares the destination IP address to its own IP address and sees they are different.
   • CIt sends an ARP request to the destination IP; if no reply is received, the destination is remote.
   • DIt performs a logical AND of the destination IP address with its own subnet mask and compares the result to its own network address.
