考题 Which of the following OSPF messages contains entire complete LSAs used during the database exchange process?() A. LSRB. LSAckC. LSUD. DDE. Hello

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

考题 When a router undergoes the exchange protocol within OSPF, in what order does it pass through each state?() A.exstart stateexchange stateloading statefull stateB.exstart statefull stateloading stateexchange stateC.Loading stateexchange statefull stateexstart stateD.exstart stateloading stateexchange statefull state

考题 Which of the following describe the process identifier that is used to run OSPF on a router?() A. It is locally significant.B. It is globally significant.C. It is needed to identify a unique instance of an OSPF database.D. It is an optional parameter required only if multiple OSPF processes are running on the router.E. All routers in the same OSPF area must have the same process ID if they are to exchange routing information.

考题 Refer to the exhibit. When running OSPF, What would cause router A not to form an adjacency with router B?() A.The loopback addresses are on different subnetsB.The value of the dead timers on the router are differentC.Route summarization is enabled on both routersD.The process indentifier on router A is different than the process identifier on router B
