CCNA IP Route Command

AE.

The command "ip route 172.16.3.0 255.255.255.0 192.168.2.4" is used to create a static route on a Cisco router. Here are the explanations of the options:

A. It establishes a static route to the 172.16.3.0 network.

This statement is true. The command "ip route" followed by the network address and subnet mask defines a static route. In this case, it defines a static route to the 172.16.3.0/24 network.

B. It establishes a static route to the 192.168.2.0 network.

This statement is not true. The IP address 192.168.2.4 in the command is the next-hop address or the exit interface for the 172.16.3.0/24 network, not the destination network.

C. It configures the router to send any traffic for an unknown destination to the 172.16.3.0 network.

This statement is not true. This command only creates a static route to the 172.16.3.0/24 network. It does not affect the router's behavior for traffic with unknown destinations.

D. It configures the router to send any traffic for an unknown destination out the interface with the address 192.168.2.4.

This statement is not true. The command only defines a static route to the 172.16.3.0/24 network. It does not affect the router's behavior for traffic with unknown destinations.

E. It uses the default administrative distance.

This statement is not true. The administrative distance is not specified in the command, so the router will use the default administrative distance for the static route, which is 1.

F. It is a route that would be used last if other routes to the same destination exist.

This statement is not true. The command only creates a static route to the 172.16.3.0/24 network, but it does not specify whether it should be used as a backup route or as the primary route. If there are other routes to the same destination, the router will use the route with the best metric or administrative distance.

In conclusion, statements A and B are true about the command "ip route 172.16.3.0 255.255.255.0 192.168.2.4".
