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2题：
A.Router(config)#router ospf 1
B.Router(config)#router ospf 0

D.Router(config-router)#network 192.168.16.0 0.0.0.255 area 0
E.Router(config-router)#network 192.168.16.0 0.0.0.255 0
F.Router(config-router)#network 192.168.16.0 255.255.255.0 area 0
第3题：
A. Apply an export policy to OSPF that exports the default route
B. Apply an import policy to OSPF that imports the default route
C. Apply the default-network command to OSPF
D. Apply the redistribute-igp command to BGP
第4题：
You have a router running BGP for the MPLS network and OSPF for the local LAN network at the sales office. A route is being learned from the MPLS network that also exists on the OSPF local network. It is important that the router chooses the local LAN route being learned from the downstream switch running OSPF rather than the upstream BGP neighbor. Also， if the local OSPF route goes away， the BGP route needs to be used. What should be configured to make sure that the router will choose the LAN network as the preferred path？（）
第5题：
Which commands are required to properly configure a router to properly configure a router to run OSPFand to add network 192.168.16.0/24 to OSPF area 0？（）
第6题：
A new router, named TK1, is being installed. You wish to add this router to your existing OSPF network. In doing so, you configure the following:TK1(config) router ospf 1TK1(config-router) network 10.10.10.0 255.255.255.0 area 0After making this change, you notice that the networks attached to TK1 are not being learned by the other OSPF routers. What could be the cause of this?（）
A. The AS is not correctly configured
B. The network subnet mask is incorrectly configured
C. The network wildcard mask is configured incorrectly
D. The network number is not correctly configured
E. The process id is configured incorrectly
F. None of the above

Each router has been configured with the appropriate network statements under router ospf 1, but the routers are not forming an adjacency. Which of the following three commands could be configured on each router to correct this problem?（）
A. RouterC(config - if)#ip ospf network broadcast RouterD(config - if)#ip ospf network broadcast
B. RouterC(config - if)#ip ospf network point - to - point RouterD(config - if)#ip ospf network point - to - point

D. RouterC(config - router)#neighbor 10.255.255.254 RouterD(config - router)#neighbor 10.255.255.253
第9题：
Half of your network uses RIPv2 and the other half runs OSPF. The networks do not communicate with each other. Which two of these factors describe the impact of activating EIGRP over each separate part？ （）
第10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?（）
