第6题:
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?()
第7题:
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?()
第8题:
R1 loses and then re - establishes neighborships with all neighbors.
R1 no longer advertises 10.1.1.0/24 to neighbors into area 1.
R1 advertises a 1 0.1.0.0/16 route into area 1 with a metric of 23 (largest metric).
R1 advertises a 10.1.0.0/16 route into area 1 with metric of 21 (lowest metric).
第9题:
The area cannot be a backbone area.
Inter area routes are suppressed.
The area has no more than 10 routers.
No virtual links are allowed.
No autonomous system border routers are allowed.
Redistribution is not allowed unless the packet is changed to a type 7 packet.

第11题:
The output lists nothing unless 10.100.0.0 has been configured as a summary rou te using the area range command.
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.
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.
None, because the Type 3 LSAs would exist only in the ABR's LSDBs.
第12题:
R1 will not create/flood a type 3 LSA for subnet 10.1.2.0/26 into area 1
R1 will not create/flood a Type 3 LSA for subnet 1 0.1.2.0/24 into area 1
R1 will not have an OSPF route for subnet 10.1.2.0/26 in its IP routing tablE
R1 will not have an OSPF route for subnet 10.1.2.0/24 in its IP routing tablE
第13题:
A. Router R1 will only establish full adjacency with the DR and BDR on broadcast multi- access networks.

C. Routers R1 and R2 are configured as stub routers for OSPF area 1 and OSPF area 2.
D. Router R1 and R2 are configured for a virtual link between OSPF area 1 and OSPF area 2.
E. The Hello parameters on routers R1 and R2 do not m atch.

D. On the ABR router ospf 10 area 3 nssa
E. On the ABR rou ter ospf 10 area 3 stub no - summary
第15题:
R1, an ABR between backbone area 0 and area 1, has intra - area routes in area 0 for 10.1.1.0/24,10.1.2.0/24, and 10.1.3.0/24. These routes have metrics of 21, 22, and 23, respectively. An engineer then adds the area 0 r ange 10.1.0.0 255.255.0.0 command under the OSPF process of R1. Which of the following is true?()
第16题:
R1 is internal to area 1, and R2 is internal to area 2. Subnet 10.1.1.0/24 exists in area 2 as a connected subnet off R2. ABR ABR1 connects area 1 to backbone area 0, and ABR2 c onnects area 0 to area 2. Which of the following LSAs must R1 use when calculating R1's best route for 10.1.1.0/24?()
第17题:
An OSPF non-backbone area allows external routes to be flooded within the area. These external routes are propagated into other areas. However, external routes from other areas are not allowed to enter this area. Which type of SPF area does this describe?()
