A. B. C. D.C
The correct answer is C.
Explanation:
In order to send all traffic without a matching routing-table entry to 192.168.1.1, we need to configure a default route on R1 that forwards all packets with no matching destination to 192.168.1.1.
Option A is incorrect because it uses the command "default-route" which is not a valid command in Cisco IOS.
Option B is incorrect because it specifies the destination as 192.168.1.1, which means that only packets with a destination of 192.168.1.1 will be forwarded to that address.
Option D is incorrect because the "ip default-gateway" command is used to set the default gateway for a device that is not performing routing, such as a host or switch. It is not used on a router that is performing routing.
Therefore, the correct answer is Option C, which uses the correct syntax for configuring a default route on a Cisco router. The command "ip route 0.0.0.0 0.0.0.0 192.168.1.1" specifies that all packets with no matching destination should be forwarded to the next-hop address of 192.168.1.1.
