Router R1 connects to a Frame Relay cloud using a multipoint subinterface, with ten PVCs associated with the subinterface.What command would make this router not use a DR, and dynamically discover OSPF neighbors?（）A. ip ospf network broadcastB. ip ospf network non - broadcastC. ip ospf network point - to - multipointD. ip ospf network point - to - multipoint non - broadcast
考题
What will happen after redistributing other routing protocol routes into OSPF? ()
A. miss the metric option in the redistribute command.B. misconfigure the metric- type option in t he redistribute command to type - 1.C. miss the subnet option in the redistribute command.D. miss the tag option in the redistribute command.
考题
Refer to the exhibit. EIGRP has been configured on router D. Router C is performing mutual redistribution between EI GRP and OSPF. While verifying that the redistribution is functioning properly, you discover that while router C has all of the EIGRP routes in its routing table, router A does not have any routes from the EIGRP domain. What on router C may be the cause o f the problem?（）A. The no auto - summary command needs to be added under router eigrp 1B. The subnets keyword was not included in the redistribute command under router ospf 1C. The metric specified for the redistributed EIGRP routes is too large; m aking the EIGRP routes unreachable by router AD. The default - information originate command needs to be added under router ospf 1E. The administrative distance of either OSPF or EIGRP must be changed so that EIGRP has a higher administrative distanc e than OSPF
考题
Refer to the exhibits. You are verifying your OSPF implementation, and it does not seem to be functioning properly. What can you conclude from the exhibit and the show running - configuration command output? （）A. The OSPF areas are not configured correctly.B. The wildcard masks for the 10.x .x.x networks are incorrect.C. The 172.16.x.x networks need to be connected to area 0 using virtual links.D. The 172.16.x.x networks are discontiguous. OSPF is automatically summarizing them to 172.16.0.0/16 and data is being black holed.E. There is not enough information to make a determination.

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

考题
You have completed an OSPF implementation, and you are verifying OSPF operation. During this verification, you notice that the OSPF route of 172.16.10.0 is repeatedly appearing and disappearing from the routing table. Further investigation finds that the OSPF CPU utilization is very high and the routers are constantly performing SPF calculations. You determine that 172.16.20.2 is the source of the 172.16.10.0 route. Using the show ip ospf database router 172.16.20.1 command, you notice that when this show command is performed repeatedly, the contents of the LSA change every few seconds. What could be the cause of this problem?（）A、OSPF authentication errors between some of the routersB、Two routers have the same OSPF router IDC、Issues with mistuned OSPF timersD、OSPF LSA pacing issues between some of the routersE、OSPF neighbor adjacency problems between some of the routers
