- destination route
- generic route
14. What are two advantages of static routing over dynamic routing? (Choose two.)
- Static routing is more secure because it does not advertise over the network.
- Static routing scales well with expanding networks.
- Static routing requires very little knowledge of the network for correct implementation.
- Static routing uses fewer router resources than dynamic routing.
- Static routing is relatively easy to configure for large networks.
15. Why would a floating static route be configured with an administrative distance that is higher than the administrative distance of a dynamic routing protocol that is running on the same router?
- to be used as a backup route
- to load-balance the traffic

- The static route is removed from the routing table.
- The router polls neighbors for a replacement route.
- The static route remains in the table because it was defined as static.
