Nokia Certified Network Routing Specialist I (NRS I) Practice Test

The command used to display the routing table on a Cisco router is "show ip route." This command provides a comprehensive view of the routing table, allowing network administrators to see the routes that the router knows about, the networks configured, and the next-hop addresses for those routes.

When executed, the output displays various important information including the destination networks, the associated metrics, and the interface through which the traffic would be sent. This is essential for troubleshooting network connectivity issues and for understanding the routing decisions being made by the router. The command is standard across many versions of Cisco IOS and is widely used by network professionals.

The other options do not reflect standard Cisco commands. "show routes" and "display routing" are not valid commands in Cisco IOS, while "view ip table" is also not a recognized command for displaying routing information. Thus, "show ip route" stands out as the precise and correct command to achieve the required outcome.
