Ccna 2 chapter 11 v4.0 answers 2011

  1. 1. www.ccna4u.infoCCNA 2 Chapter 11 V4.0 Answers1.Refer to the exhibit. All routers are running OSPF. What cost would JAX put in itsrouting table for the network?21561564178517872. Refer to the exhibit. Router1and Router2 are running OSPF. The show ip ospf neighbor command reveals noneighbors. What is a possible cause?
  2. 2. www.ccna4u.infoOSPF autonomous system IDs do not match.OSPF process IDs do not match.OSPF network types are identical.OSPF hello or dead timers do not match.3. A fully converged five router OSPF network has been running successfully forseveral weeks. All configurations have been saved and no static routes are used. Ifone router looses power and reboots, what information will be in its routing tableafter the configuration file is loaded but before OSPF has converged?All routes for the entire network will be present.Directly connected networks that are operational will be in the routing table.Because the SPF algorithm has not completed all calculations, no routes will be in thetable.A summary route for all previously learned routes will automatically appear in therouting table until all LSPs have been received by the router.4.Refer to the exhibit. What configuration statements would give the results that areshown in the output of the show ip protocols command?B(config)# int fa0/0B(config-if)# router-id int lo0B(config-if)# ip address router ospf 1B(config-router)# router-id (config)# router ospf 1B(config-router)# ip address
  3. 3. www.ccna4u.infoRefer to the exhibit. When OSPF is operational in the exhibited network, whatneighbor relationship is developed between Router1 and Router2?A FULL adjacency is formed.A 2WAY adjacency is formed.Router2 will become the DR and Router1 will become the BDR.Both routers will become DROTHERS.6. What does OSPF use to calculate the cost to a destination network?bandwidthbandwidth and hop countbandwidth and reliabilitybandwidth, load, and reliablity7.
  4. 4. www.ccna4u.infoRefer to the exhibit. The routers in the exhibit are using default OSPF configurationsettings to advertise all attached networks. If all of the routers start at the sametime, what will be the result of the DR and BDR elections for this single area OSPFnetwork? (Choose three.)HQ will be DR for A will be DR for will be BDR for A will be DR for will be DR for will be BDR for What does OSPF use to reduce the number of exchanges of routing informationin networks where large numbers of neighbors are present? (Choose two.)root routerbackup root routerdomain routerbackup domain routerdesignated routerbackup designated router9.Refer to the exhibit. All routers have been configured with the interface prioritiesthat are shown. All routers were restarted simultaneously. The results of theDR/BDR election are shown. What can be concluded about this network?Router C cannot win a DR election under any circumstances.If the link for interface goes down, router B will become the new DR.
  5. 5. www.ccna4u.infoThe highest router ID was most likely determined via an OSPF router-id statement orstatements.If a new router is added with a higher router ID than router D, it will become the DR.10.Refer to the exhibit. Router A is correctly configured for OSPF. Which OSPFconfiguration statement or set of statements was entered for router B to generatethe exhibited routing table?B(config-router)# network area 0B(config-router)# network area 0B(config-router)# network area 0B(config-router)# network area 0B(config-router)# network area 011.Refer to the exhibit. Assuming that the routers have default interface OSPFpriorities and no configured loopback interfaces, what two roles will router B play
  6. 6. www.ccna4u.infoon each network segment? (Choose two.)DR for network for network on for network for network on network to the exhibit. Routers A, B, C, and D are all running OSPF with defaultrouter IDs and OSPF interface priorities. Loopback interfaces are not configuredand all interfaces are operational. Router D is the DR and router C is the BDR.What happens immediately after the following commands are entered on router A?A(config)# interface fa0/0A(config-if)# ip ospf priority 255A will become the DR. D will become the BDR.A will become the DR. C will remain the BDR.D will remain the DR. A will become the BDR.D will remain the DR. C will remain the BDR.13. What range of networks will be advertised in the OSPF updates by thecommand Router1(config-router)# network area 100? through through through through through
  7. 7. www.ccna4u.infoRefer to the exhibit. RouterA, RouterB, and RouterC in the diagram are runningOSPF on their Ethernet interfaces. Router D was just added to the network.Routers are configured with the loopback interfaces (Lo 0) that are shown in theexhibit. What happens to the OSPF DR/BDR after RouterD is added to thenetwork?RouterB takes over as DR and RouterD becomes the BDR.RouterD becomes the BDR and RouterA remains the DR.RouterD becomes the DR and RouterA becomes the BDR.RouterC acts as the DR until the election process is complete.RouterD becomes the DR and RouterB remains the BDR.There is no change in the DR or BDR until either current DR or BDR goes down.15.Refer to the exhibit. How many OSPF adjacencies must be formed to build thecomplete topology if a DR or BDR were not elected in this OSPF network?
  8. 8. www.ccna4u.info45671016. What is the default administrative distance for OSPF?9010011011512017.Refer to the exhibit. Which command sequence on RouterB will redistribute agateway of last resort to the other routers in OSPF area 0?RouterB(config)# router ospf 10 RouterB(config-router)# gateway-of-last-resort172.16.6.6RouterB(config)# ip route serial 0/0/0RouterB(config)# ip route router ospf 10RouterB(config-router)# default-information originateRouterB(config)# router ospf 10RouterB(config-router)# default-network area 0RouterB(config)# ip route ip default-route router ospf 10RouterB(config-router)# redistribute ip default-route18. Which two statements describe the use of OSPF DR/BDR elections? (Choosetwo.)Elections are always optional.
  9. 9. www.ccna4u.infoElections are required in all WAN networks.Elections are required in point-to-point networks.Elections are required in broadcast multiaccess networks.Elections are sometimes required in NBMA networks.19.Refer to the exhibit. What does the “2″ stand for in the router ospf 2 statement?The number 2 is the autonomous system number.The number 2 indicates the number of networks advertised by OSPF.The number 2 identifies this particular instance of OSPF on this router.The number 2 indicates the priority of the OSPF process on this router.20.Refer to the exhibit. The network administrator wants to set the router ID ofRouter1 to What steps can the administrator take to accomplish this?shut down the loop back interfaceuse the OSPF router-id commanduse the clear ip ospf process commandnothing, the router-id of Router1 is already to the exhibit. What must be received between neighbors to prevent the deadtime that is shown in the exhibit from reaching zero?any traffic through the router interfaces
  10. 10. www.ccna4u.inforouting database updateshello packetsBPDU packets22.Refer to the exhibit. What does the “O*E2″ from the “O*E2 [110/1] via192.168.1.1, 00:05:34, Serial0/0″ line represent?an internal type 2 OSPF external OSPF route at least two hops external OSPF route from two different external OSPF route that will not increment in cost.a default route.The route was distributed into OSPF from a type 2 router.23.Refer to the exhibit. Which network command or set of commands will cause OSPFto be enabled for any R1 interface connected to the exhibited subnets?R1(config-router)# network area 0R1(config-router)# network area 0 R1(config-router)# network10.1.1.0 area 0 R1(config-router)# network area 0R1(config-router)# network area 0R1(config-router)# network area 0R1(config-router)# network area 024.

What three parameters must be indentical between OSPF routers in order toform an adjacency? (Choose three.)area idK-valuesmetric valuehello intervalnetwork typeinterface typeRelated Posts • CCNA 2 Skill test 2011 • CCNA 2 Chapter 10 V4.0 Answers • CCNA 2 Chapter 9 V4.0 Answers • CCNA 2 Chapter 8 V4.0 Answers • CCNA 2 Chapter 7 V4.0 Answers • CCNA 2 Chapter 6 V4.0 Answers • CCNA 2 Chapter 5 V4.0 Answers • CCNA 2 Chapter 4 V4.0 Answers • CCNA 2 Chapter 3 V4.0 Answers • CCNA 2 Chapter 2 V4.0 Answers • CCNA 2 Chapter 1 V4.0 Answers • CCNA 2 Final Exam AnswersTags: CCNA 2, CCNA 2 Final, ccna 2 final answers, CCNA 2 Final Exam, ccna 2 finalexam 2011, CCNA 2 Final Exam Answers, ccna 2 final exams, ccna 2 final questions,ccna final exam 2011← CCNA 1 Final Exam Answers CCNA 3 Final Exam Answers (2010) →Leave a ReplyYour email address will not be published.
