Final answer:
The most specific route for the destination IP address 10.1.1.1 is option C: O 10.1.1.0/24 via 192.168.200.2, which would be used to forward the packet.
Explanation:
To determine which route should be used to forward a packet with a source IP address of 192.168.10.1 and a destination IP address of 10.1.1.1, the router will consult its routing table and choose the most specific matching route for the destination IP address. Looking at the provided routes:
- A. C 192.168.10.0/30 is directly connected, GigabitEthernet0/1
- B. S 10.1.0.0/16 is directly connected, GigabitEthernet0/0
- C. O 10.1.1.0/24 [110/65] via 192.168.200.2, 00:01:20, Serial0/1/0
- D. S* 0.0.0.0/0 [1/0] via 172.16.1.1
Option C is the most specific route that matches the destination IP address because the subnet mask /24 narrows down to the exact network in which the destination IP resides. Therefore, option C would be used to forward the packet.
