第13题:
Refer to the exhibit. You have completed an OSPF implementation, and you are verifying OSPF operation. You notice that router A and router B are stuck in the two - way state. From the show ip ospf interface command output, what is the cause of this issue?()
A. All OSPF implementations must have at le ast one interface in area 0.
B. You are attempting to run in the broadcast mode over an NBMA interface.
C. Both routers are configured to function as a BDR; therefore, there is no DR router.
D. Someone has changed the OSPF router ID; therefore you must clear the OSPF process.
E. The OSPF priority is set to 0 on both routers; therefore neither can become the DR.
第14题:
A. point-to-point
B. Backbone area 0
C. Broadcast multicast
D. Non-broadcast multi-access
E. The DR/BDR process is done for all interface types
第15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 interface
B. The ip ospf network non -broadcast command should be configured on each Frame Relay interface
C. Th e ip ospf priority value on the spoke routers should be set to 0
D. The ip ospf priority value on the hub router should be set to 0
E. The neighbor command should be configured under the OSPF routing process on all routers
第16题:
The OSPF process has been started and the networks have been configured for Area 0 as shown in the diagram. The network administrator has several options for configuring RouterB to ensure that it will be preferred as the designated router (DR) for the 172.16.1.0 /24 LAN segment. What configuration tasks could be used to establish this preference (Choose three.)()。
A.Configure the priority value of the Fa0/0 interface of RouterB to a higher value than any other interface on the Ethernet network.
B.Change the router id of Router B by assigning the IP address 172.16.1.130/24 to the Fa0/0 interface of RouterB.
C.Configure a loopback interface on RouterB with an IP address higher than any IP address on the other routers.
D.Change the priority value of the Fa0/0 interface of RouterB to zero.
E.Change the priority values of the Fa0/0 interfaces of RouterA and RouterC to zero.
F.No further configuration is necessary.
第17题:
If all OSPF routers in a single area are configured with the same priority value,what value dose a router use for the ODPF router ID in the absence of a loopback interface?()
第18题:
When verifying OSPF virtual link problems, which is an important item to check on the two transit OSPF routers?()
第19题:
What is the purpose of the OSPF router ID in a OR/BOR election?()
第20题:
If all OSPF routers on a broadcast network have the same OSPF priority, what parameter is used to determine the new BDR at the time of a DR failure?()
第21题:
Nothing. OSPF will determine the most optimal path for routing data by default.
Adjust the hello and dead timers for more rapid detection of link failures.
Increase the reference - bandw idth used to calculate the interface default metrics, on all routers in your network.
Set the priority values on every broadcast interface to ensure that the designated and backup designated routers are the routers with the most processor and memory resources.
