第1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.


参考答案：E

B. When you use the passive - interface command with RIPv2, multicasts are sent out the specified interface

C. After the router rip and passive -interface s0/0 commands have been issued, the s0/0 interface will not send any RIP updates, but will receive routing updates on that interface

D. When you use the passive - interface command with EIGRP, hel lo messages are not sent out the specified interface

E. After the router eigrp 10 and passive - interface s0/0 commands have been issued, the s0/0 interface will not send any EIGRP updates, but will receive routing updates on that interface

第8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 routers

B. Two routers have the same OSPF router ID

C. Issues with mistuned OSPF timers

D. OSPF LSA pacing issues between some of the routers

E. OSPF neighbor adjacency problems between some of the routers


参考答案：B
