Refer to the exhibit. A packet with source 172.18.33.2 is being sent to 172.18.32.38. Where does the router forward this packet?

A 10.1.1.1
B 10.1.1.3
C Loopback0
D GigabitEthernet0/0

Explanation

Routers choose the route with the longest matching prefix. Although several routes match 172.18.32.38, the most specific match is 172.18.32.36/30, which is directly connected on GigabitEthernet0/0. Therefore, the packet is forwarded out GigabitEthernet0/0.
