A router leams about a remote network from EIGRP.OSPF. and a static route. Assuming all routing protocols are using their default administrative distance, which route will the router use to forward data to the remote network?（）A. The router will use the static route.B. The router will use the OSPF route.C. The route will use the EIGRP route.D. The router will load balance and use all three routes.
When an OSPF design is planned, which implementation can help a router not have memory resource issues?() A. Have a backbone area (area 0) with 40 routers and use default routes to reach external destinationsB. Have a backbo ne area (area 0) with 4 routers and 30,000 external routes injected into OSPFC. Have less OSPF areas to reduce the need for interarea route summarizationsD. Have multiple OSPF processes on each OSPF router. Example, router ospf 1, router ospf 2
