An OSPF non-backbone area allows external routes to be flooded within the area. These externalroutes are propagated into other areas. However, external routes from other areas are not allowed to enter this area. Which type of OSPF area does this describe?（）A. stub areaB. transit areaC. border areaD. not-so-stubby area

To make OSPF area 4 totally stubby, the following command was issued on the ABR in router configuration mode: area 4 stub.Which two things need to be done to finish making area 4 a totally stubby area?（）A. Apply the area 4 stub command to all routers in the areaB. On the ABR, use the area 4 stub command with the no - summary keywordC. On the ABR, specify a default cost for the area with the area default - cost commandD. On the ABR, use the default - information originate command to inject a default route into area 4E. Use the auto - cost command on each router in the area to automatically determine the cost to other OSPF areas

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

Which description regarding OSPF Network LSAs is correct?()
A. They are originated by Area Border Router and are sent into a single area to advertise an Autonomous System Border Router.B.

They include all attached routers including the DR itself.D. They are originated by every router in the OPSF network. They include all routers on the link, interfaces, the cost of the link, and any known neighbor on the link.
