Which routers must be configured with the same authentication string when configuring OSPFauthentication?()
A. all routers on a linkB. all routers in an areaC. all external OSPF peersD. all routers in an OSPF domain
考题
if all OSPF routers on a broadcast network have the same OSPF priority, which parameter is used to determine the new BDR at the time of a DR failure?()
A.AB.BC.CD.D
考题
Ten routers, R1 through R10, connect in a partial mesh over Frame Relay. For the mesh, R1 and R2 have PVCs connected to all other routers, but Routers R3 through R10 act as branch routers, with only two PVCs - one to R1 and one to R2. The routers u se IP subnet 10.1.1.0/24, with addresses 10.1.1.1, 10.1.1.2, and so on, through 10.1.1.10, respectively. The routers all use Inverse ARP to learn Frame Relay mapping information. All routers use a multipoint subinterface with network type point - tomultip oint nonbroadcast. A co - worker‘s implementation plan lists lots of configuration commands related to this design. The design states that all hosts should be able to ping all other hosts.Which commands are required for proper functioning of OSPF in this case?（）A. frame - relay map commands on R3 - R10 referencing the other routers in this groupB. Nine OSPF neighbor commands on each routerC. Nine OSPF neighbor commands on R1 and R2, with only two such commands on R3 - R10D. R1 and R2 with ip ospf prio rity 1 commands to ensure they become DR and BDRE. R3 - R10 with ip ospf priority 0 commands to ensure they do not become DR or BDR
考题
Routers R1, R2, R3, and R4 connect to the same 10.10.10.0/24 LAN- based subnet. OSPF is fully working in the subnet. Later, R5, whose OSPF priority is higher than the other four routers, joins the subnet.Which of the following are true about the OSPF database exchange process over this subnet at this point?（）A. R5 will send its DD, LSR, and LSU packets to the 224.0.0.5 all - DR - routers multicast address.B. R5 will send its DD, LSR, and LSU pack ets to the 224.0.0.6 all - DR - routers multicast address.C. The DR will inform R5 about LSAs by sending its DD, LSR, and LSU packets to the 224.0.0.6 all- SPF - routers multicast address.D. The DR will inform R5 about LSAs by sending its DD, LSR, and LSU pa ckets to the 224.0.0.5 all- SPF - routers multicast address.
考题
When verifying the OSPF link state database, which type of LSAs should you expect to see within the different OS PF area types?()
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.
考题

A. All entries in the topology database will be included on each router.B. All routers in the same OSPF area will have one topology database.C. The Dijkstra algorithm is used in the creation of the topology database.D. LSA packets are used to update and maintain the topology database.
考题
What are two characteristics of the OSPF process identifier?()
A. It is needed to identify a unique instance of an OSPF database.B. It is an optional parameter only necessary if multiple OSPF processes are used.C. It is locally significant.D. It is globally insignificantE. All routers in the same OSPF area must have the same process ID to exchange routing information.
考题
An etwork administrator has enabled OSPF across an NBMA network and has issued the command ip ospf network nonbroadcast. Given those facts, which two statements are true?()
A. Interfaces will automatically detect and build adjacencies with neighbor routersB. DR and BDR elections will not occurC. DR and BDR elections will occurD. The neighbor command is required to build adjacenciesE. All routers must be configured in a fully meshed topology with all other routers
考题
OSPF is configured over a Frame Relay network as shown in the exhibit. All PVCs are active.However, R1 and R3 fail to see all OSPF routes in their routing tables. The show ip ospf neighbor command executed on R2 shows the state of t he neighbors. What should be done to fix the problem? （）A. The ip ospf network broadcast command should be configured on each Frame Relay interfaceB. The ip ospf network non -broadcast command should be configured on each Frame Relay interfaceC. Th e ip ospf priority value on the spoke routers should be set to 0D. The ip ospf priority value on the hub router should be set to 0E. The neighbor command should be configured under the OSPF routing process on all routers
