Refer to the exhibit. What will the router do with a packet that has a destination IP address of 192.168.12.227?
- Drop the packet.
- Send the packet out the Serial0/0/0 interface.
- Send the packet out the GigabitEthernet0/0 interface.
- Send the packet out the GigabitEthernet0/1 interface.
Answers Explanation & Hints:
After a router determines the destination network by ANDing the destination IP address with the subnet mask, the router examines the routing table for the resulting destination network number. When a match is found, the packet is sent to the interface associated with the network number. When no routing table entry is found for the particular network, the default gateway or gateway of last resort (if configured or known) is used. If there is no gateway of last resort, the packet is dropped. In this instance, the 192.168.12.224 network is not found in the routing table and the router uses the gateway of last resort. The gateway of last resort is the IP address of 22.214.171.124. The router knows this is an IP address that is associated with the 126.96.36.199 network. The router then proceeds to transmit the packet out the Serial0/0/0 interface, or the interface that is associated with 188.8.131.52.
