Which two statements are true about the command ip route 172.16.3.0 255.255.255.0 192.168.2.4? (Choose two.)

AIt establishes a static route to the 172.16.3.0 network. (correct answer)
BIt establishes a static route to the 192.168.2.0 network.
CIt configures the router to send any traffic for an unknown destination to the 172.16.3.0 network.
DIt configures the router to send any traffic for an unknown destination out the interface with the address 192.168.2.4.
EIt uses the default administrative distance. (correct answer)
FIt is a route that would be used last if other routes to the same destination exist.

Reveal answer & explanation

Correct answer: A, E

The correct answer is A, E. Option A: It establishes a static route to the 172.16.3.0 network. Option E: It uses the default administrative distance.

Explanation

A static route is manually configured and does not adapt automatically to topology changes. Administrative distance ranks the trustworthiness of routes learned from different sources.
