   A host with IP 10.1.1.5 and subnet mask 255.255.255.0 needs to send a packet to 10.1.2.10. The host's default gateway is 10.1.1.1. What does the host do with the packet?

   • ABroadcasts the packet to all hosts on the local network
   • BSends it directly to 10.1.2.10 because it is a valid IP address
   • CForwards it to 10.1.1.1 because the destination is on a different subnet
   • DDrops the packet because there is no route to 10.1.2.0/24 in its routing table
