What is the correct command to add a static route to a class-c-network 10.2.10.0 via a gateway of 172.16.1.1?
A . ip-route 10.2.10.0/24 172.16.1.1

C. ip route 10.2.10.0/24.172.16.11
D. ip route-static 10.2 10.0.255.255.255.0 172.16.1.1

Answer: A

Explanation:

The correct command to add a static route to a class-c-network 10.2.10.0 via a gateway of 172.16.1.1 is ip-route 10.2.10.0/24 172.16.1.1. This command specifies the destination network address (10.2.10.0) and prefix length (/24) and the next-hop address (172.16.1 .1) for reaching that network from the switch. The other commands are either incorrect syntax or incorrect parameters for adding a static route.
