Which of the following are functions of a routing protocol? (Choose two answers.)
- Advertising known routes to neighboring routers
- Learning routes for subnets directly connected to the router
- Learning routes and putting those routes into the routing table for routes advertised to the router by its neighboring routers
- Forwarding IP packets based on a packet’s destination IP address
Explanation: Routers do all the actions listed in all four answers; however, the routing protocol does the functions in the two listed answers. Independent of the routing protocol, a router learns routes for IP subnets and IP networks directly connected to its interfaces. Routers also forward (route) IP packets, but that process is called IP routing, or IP forwarding, and is an independent process compared to the work of a routing protocol.
