You have connected a Multilayer switch to an Internet Service Provider router that has the 172.16.31.254 IP address. What configuration line do you…

To enable a device on a local network to access the internet, a default route must be configured. This route directs all traffic for which the switch does not have a more specific route to a next-hop gateway, which in this case is the ISP router. The command ip route 0.0.0.0/0 172.16.31.254 configures a static default route. The 0.0.0.0/0 prefix represents any destination network, and 172.16.31.254 is the IP address of the ISP router that will forward the traffic to the internet. This is the standard syntax for modern network operating systems like ArubaOS-CX.

A. This option uses incorrect command syntax and parameter order for an Aruba switch.

C. The routing command is not used for this purpose, and a subnet mask should not be applied to the next-hop gateway address.

D. The ip routing command is used to enable the routing function globally on the switch, not to configure a specific static route.
