The real difference between plants and animals ____ what they do, and not in what they seem to be.A: lies inB: lies withC: lies downD: lies up
IS － IS is often considered an alternative to OSPF in the IP world. Which two statements identify similarities between IS －IS and OSPF?() A. support for designated intermediate systems and backup designated intermediate systemsB. support for multip le areas per routerC. support for classless routingD. support for address summarization between areasE. support for both DIS adjacencies and neighbor adjacencies
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
An etwork administrator has enabled OSPF across an NBMA network and has issued the command ip ospf network nonbroadcast. Given those facts, which two statements are true?() A. Interfaces will automatically detect and build adjacencies with neighbor routersB. DR and BDR elections will not occurC. DR and BDR elections will occurD. The neighbor command is required to build adjacenciesE. All routers must be configured in a fully meshed topology with all other routers
What are two Cisco IOS commands that can be used to view neighbor adjacencies?() A. show ip ospf interfacesB. show ip ospf protocolsC. show ip ospf neighborsD. show ip ospf database
While troubleshooting a routing problem on the company EIGRP network you discover that one ofthe routers is failing to establish adjacencies with its neighbor. What is a likely cause of thisproblem between neighbors？（）A、The K-values do not matchB、The hold times do not matchC、The hello times do not matchD、The AS numbers do not match
IS - IS is often considered an alternative to OSPF in the IP world. Which two statements identify similarities between IS -IS and OSPF?（）A、support for designated intermediate systems and backup designated intermediate systemsB、support for multip le areas per routerC、support for classless routingD、support for address summarization between areasE、support for both DIS adjacencies and neighbor adjacencies
The OSPF hello protocol performs which of the following tasks?（）A、It provides dynamic neighbor discoveryB、It detects unreachable neighbors in 90 second intervalsC、It maintains neighbor relationshipsD、It negotiates correctness parameters between neighboring interfacesE、It uses timers to elect the router witch the fastest links as the designated routerF、It broadcasts hello packets throughout the internetwork to discover all routers that are running OSPF

Which of the following are correct statements？（）A、EIGRP advertises the best routes to its neighborB、EIGRP uses "cost" to determine best pathC、EIGRP allows unequal cost load balancingD、OSPF requires neighbor adjacencies before updates are sentE、EIGRP advertises all routes to its neighborF、OSPF allows unequal cost load balancing
What are two Cisco IOS commands that can be used to view neighbor adjacencies?（）A、show ip ospf interfacesB、show ip ospf protocolsC、show ip ospf neighborsD、show ip ospf database
You have just completed an OSPF implementation. While executing your verification plan, you determine that R1 is not able to establish full OSPF adjacency with R2. The show ip ospf neighbor comman d output on R1 shows that R2 is stuck in the INIT state. What could be the cause of this problem?（）A、DR and BDR election errors between R1 and R2.B、The R2 router has not received the OSPF hello packets from the R1 router.C、Mismatched interface ma ximum transmission unit (MTU) configuration between the R1 and R2.D、Mismatched OSPF hello interval configuration between the R1 and R2E、Corrupted LSAs exchanges between the R1 and R2.
