Show answer and explanation
Correct answer: A
Explanation
A default route is used to forward packets for destinations that are not explicitly listed in the routing table. The command ip route 0.0.0.0 0.0.0.0 192.168.1.1 creates a default route that directs all traffic for unknown destinations to the next-hop address 192.168.1.1.
- A. Correct.
This command configures a default route, which forwards all traffic for unknown destinations to the specified next-hop IP address, 192.168.1.1.
- B. Incorrect.
This is incorrect because the command does not specifically define routes for local subnets. It is a default route for unknown destinations.
- C. Incorrect.
This is incorrect because the command does not block traffic. Instead, it forwards traffic to the next-hop address.
- D. Incorrect.
This is incorrect because the command defines a default route for all unknown destinations, not just for the 192.168.1.1 network.
