1.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

2.Refer to the exhibit. OSPF is configured on all routers in the network. Area 5 is configured as an NSSA areA. The RIPv2 routes are redistributed into the OSPF domain on router R5. What two types of LSAs will be originated by router R5?（）A. type 1 Router LSAB. type 2 Network LSAC. type 3 Network Summary LSAD. type 4 ASBR Summary LSAE. type 5 AS External LSAF. type 7 NSSA External LSA

3.Refer to the exhibit. Will redistribute d RIP routes from OSPF Area 2 be allowed in Area 1? ()A. RIP routes will be allowed in Area 1 only if they are first redistributed into EIGRP.B. Because NSSA will discard type 7 LSAs, redistributed RIP routes will not be allowed in Area 1.C. Redistrib uted RIP routes will be allowed in Area 1 because they will be changed into type 5 LSAs in Area 0 and passed on into Area 1.D. Redistributed RIP routes will be allowed in Area 1 because they will be changed into type 7 LSAs in Area 0 and passed on into Area 1.E. Because Area 1 is an NSSA, redistributed RIP routes will not be allowed.

4.Which of the following is true about routers internal to a totally NSSA area?()A. Routers cannot redistribute external routes into the area.B. Routers should have zero Type 3 LSAs in their LSDBs.C. Routers should have zero Type 5 LSAs in their LSDBs.D. Routers should learn default routes from the ABRs attached to the area.
