单选题Which router translates the Type 7 LSAs into Type 5 LSAs, according to RFC 1587 (OSPF NSSAOption) in an OSPF NSSA with more than one ABR?（）A The router receiving the route translates the Type 7 LSA into a Type 5 LSA.B The ABR with the lowest router ID

A verification plan shows a network diagram with branch office Routers B1 through B100, plus two ABRs, ABR1, and ABR2, all in area 100. The branches connect to the ABRs using Frame Relay point - to - point subinterfaces. The verification plan lists the output of the show i p ospf database summary 10.100.0.0 command on a router B1, one of the branches.Which of the following is true regarding the output that could be listed for this command?（）

A. The output lists nothing unless 10.100.0.0 has been configured as a summary rou te using the area range command.

B. If 10.100.0.0 is a subnet in area 0, the output lists one Type 3 LSA, specifically the LSA with the lower metric when comparing ABR1‘s and ABR2‘s LSA for 10.100.0.0.

C. If 10.100.0.0 is a subnet in area 0, the output lists two Type 3 LSAs, one each created by BR1 and ABR2.

D. None, because the Type 3 LSAs would exist only in the ABR‘s LSDBs.

A. All OSPF routers in stubby areas can have type 3 LSAs in their database.

B. All OSPF routers in stubby areas can have type 7 LSAs in their database.

C. All OSPF routers in totally stubby areas can have type 3 LSAs in their database.

D. All OSPF routers in totally stubby areas can have type 7 LSAs in their database.

E. All OSPF routers in NSSA areas can have type 3 LSAs in their database.

F. All OSPF routers in NSSA areas can have type 7 LSAs in their database.

A. Type 7 LSAs

B. Type 4 summary LSAs

C. Type 3 summary LSAs

D. Type 5 AS-external LSAs

A.It is used for type 1 router LSA

B.Highest IP address of the loopback is used

C.router-id needs to be matched on ospf neighbors

D.router-id is 16 bit

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 LSA

B. type 2 Network LSA

C. type 3 Network Summary LSA

D. type 4 ASBR Summary LSA

E. type 5 AS External LSA

F. type 7 NSSA External LSA

A. Never use passive interfaces.

B. Use NSSA areas from the core down.

C. Use totally stub areas to stop type 3 LSAs.

D. Use the lowest Ethernet interface IP address as the router ID.

E. Tune OSPF timers to enable OSPF to achieve quicker convergence.

A. The router receiving the route translates the Type 7 LSA into a Type 5 LSA.

B. The ABR with the lowest router ID translates all Type 7 LSAs into Type 5 LSAs.

C. The ABR with the highest router ID translates all Type 7 LSAs into Type 5 LSAs.

D. All ABRs translate the Type 7 LSAs into Type 5 LSAs depending on which one has the lowest cost to the route.
