Answer options

• A. R1#config t R1(config)#ip routing R1(config)#ip route default-route 192.168.1.1
• B. R1#config t R1(config)#ip routing R1(config)#ip route 192.168.1.1 0.0.0.0 0.0.0.0
• C. R1#config t R1(config)#ip routing R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.1.1
• D. R1#config t R1(config)#ip routing R1(config)#ip default-gateway 192.168.1.1

Correct answer: C

Explanation

The correct answer is C because it specifies a default route (0.0.0.0/0) that directs all traffic without a matching entry to 192.168.1.1. Option A incorrectly uses 'default-route,' which is not a valid command, while option B incorrectly formats the route. Option D sets a default gateway but does not perform routing, making it ineffective for this purpose.
