The Corporate router receives an IP packet with a source IP address of 192.168.214.20 and a destination address of 192.168.22.3. Looking at the output from the Corporate router, what will the router do with this packet?Corp#sh ip route[output cut]R 192.168.215.0 [120/2] via 192.168.20.2, 00:00:23, Serial0/0R 192.168.115.0 [120/1] via 192.168.20.2, 00:00:23, Serial0/0R 192.168.30.0 [120/1] via 192.168.20.2, 00:00:23, Serial0/0C 192.168.20.0 is directly connected, Serial0/0C 192.168.214.0 is directly connected, FastEthernet0/0

The packet will be routed out the Fa0/0 interface.
The packet will be routed out the S0/0 interface.
The packet will be discarded.
