Which statement describes a route that has been learned dynamically?
It is automatically updated and maintained by routing protocols.
It is unaffected by changes in the topology of the network.

It is identified by the prefix C in the routing table.
Compared with dynamic routes, what are two advantages of using static routes on a router? (Choose two.)
They Improve network security
They use fewer router resources
They take less time to converge when the network topology changes
They improve the efficiency of discovering neighboring networks.

A network administrator adds the default-information originate command to the configuration of a router that uses RIP as the routing protocol. What will result from adding this command?
The router will only forward packets that originate on directly connected networks.
The router will propagate a static default route in its RIP updates, if one is present
The router will be reset to the default factory information
The router will not forward routing information that is learned from other routers
