If all OSPF routers on a broadcast network have the same OSP

A. area ID

B. router ID

C. loopback address

D. IP address of interface on broadcast network

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.

A. all routers on a link

B. all routers in an area

C. all external OSPF peers

D. all routers in an OSPF domain

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 insignificant

E. All routers in the same OSPF area must have the same process ID to exchange routing information.

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

Refer to the exhibit. Two routers are connected by Frame Relay and are running OSPF bet ween them. 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

C. RouterC(config - router)#neighbor 10.100. 100.4 RouterD(config - router)#neighbor 10.100.100.3

D. RouterC(config - router)#neighbor 10.255.255.254 RouterD(config - router)#neighbor 10.255.255.253

A. Router R1 will only establish full adjacency with the DR and BDR on broadcast multi- access networks.

B. Router R2 has been elected as a DR for the broadcast multiaccess network in OSPF area 1.

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.

A.A

B.B

C.C

D.D

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.

A. Interfaces will automatically detect and build adjacencies with neighbor routers

B. DR and BDR elections will not occur

C. DR and BDR elections will occur

D. The neighbor command is required to build adjacencies

E. All routers must be configured in a fully meshed topology with all other routers
