All routes withthe same lowest administrative distance are added to the routing table.The router installs all routes in the routing table but uses the route with the bestmetric most when load balancing.41. Refer to the exhibit. What summary address can Router2 advertise toRouter1 to reach the three networks on Routers 3, 4, and 5 withoutadvertising any public address space or overlapping the networks onRouter1?172.16.0.0/8172.16.0.0/10172.16.0.0/13172.16.0.0/20172.16.0.0/2442. What is the purpose of the TTL field within an IP packet header?clears an unreachable route from the routing table after the invalid timer expires.prevents regular update messages from inappropriately reinstating a route that mayhave gone bad.removes an unreachable route from the routing table after the flush timer expireslimits the period of time or number of hops a packet can traverse through thenetwork before it should be discarded.used to mark the route as unreachable in a routing update that is sent to otherrouters43.
Refer to the exhibit. Hosts on the BOS Fa0/0 LAN are able to ping theFa0/1 interface on the JAX router and all interfaces on the BOS and ORLrouters. Why would hosts from the 10.0.0.0/24 network not be able to pinghosts on the Fa0/0 LAN of the JAX router?The JAX router has the wrong process ID.The JAX router needs the network 10.0.0.0 0.0.0.255 area 0 command.The JAX router needs the network 192.168.3.0 0.0.0.255 area 0 command.The BOS router needs the network 192.168.3.0 0.0.0.255 area 0 command.44. What command would the network administrator apply to a router thatis running OSPF to advertise the entire range of addresses included in172.16.0.0/19 in area 0?R1(config-router)# network 172.16.0.0 0.0.0.255 area 0R1(config-router)# network 172.16.0.0 0.0.3.255 area 0R1(config-router)# network 172.16.0.0 0.0.15.255 area 0R1(config-router)# network 172.16.0.0 0.0.31.255 area 045.
What are two tasks that must be completed before two routers can useOSPF to form a neighbor adjacency? (Choose two.)The routers must elect a designated router.The routers must agree on the network type.The routers must use the same dead interval.The routers must exchange link state requests.Стр.

Which statement is true concerning the routingconfiguration?Using dynamic routing instead of static routing would have required fewerconfiguration steps.The 10.1.1.0/24 and 10.1.2.0/24 routes have adjacent boudaries and should besummarized.The static route will not work correctly.Packets routed to the R2 ethernet interface require two routing table lookups.47.
What can be determined from the output shown in the exhibit? (Choosetwo.)Annapolis is a 2611 router that is connected to the S0/0 interface of the Montgomeryrouter.All of the routers are connected to Montgomery through an Ethernet switch.Montgomery has Layer 2 connectivity with Cumberland.Layer 3 connectivity is operational for all of the devices listed in the Device IDcolumn.An administrator consoled into the Waldorf router can ping the Brant router.Brant, Fisherman, and Potomac are directly connected to Montgomery.48. What is the function of the OSPF LSU packet?used to confirm receipt of certain types of OSPF packetsused to establish and maintain adjacency with other OSPF routersused to request more information about any entry in the BDRused to announce new OSPF information and to reply to certain types of requests50.
Refer to the exhibit. All routers in the network are running RIPv2 andEIGRP with default routing protocol settings and have interfaces configuredwith the bandwidths that are shown in the exhibit. Which protocol will beused and how will traffic between the Router1 LAN and Router5 LAN berouted through the network?RIPv2 will load balance across both paths between Router1 and Router5.EIGRP will load balance across both paths between Router1 and Router5.RIPv2 traffic will use the path Router1, Router2, Router5 because it has the leasthops.EIGRP traffic will use the path Router1, Router3, Router4, Router5 because it hasthe best metric.51. Refer to the exhibit. A network administrator is trying to figure out whyBOS does not have the 10.0.0.0/24 network in its routing table.
All routersare configured for OSPF in area 0. The links between the routers areoperational and the administrator is able to ping between all routerinterfaces. What is a logical next step that the network administratorshould take to troubleshoot the problem?Reboot the routers.Change the OSPF process ID on all of the routers to 0.Check to see if the cable is loose between BOS and JAX.Check to see if CDP packets are passing between the routers.Use show and debug commands to determine if hellos are propagating.52.
Refer to the exhibit. The network is using the RIPv2 routing protocol. Ifnetwork 10.0.0.0 goes down, what mechanism will prevent Router1 fromadvertising false routing information back to Router2?triggered updatespoison reverseholddown timerssplit horizon53. Which two router component and operation pair are correctlydescribed? (Choose two.)DRAM - loads the bootstrapRAM - stores the operating systemFlash - executes diagnostics at bootupNVRAM - stores the configuration fileROM - stores the backup configuration filePOST - runs diagnostics on hardware modules54.
Which of the following are primary functions of a router? (Choose two.)packet switchingmicrosegmentationdomain name resolutionpath selectionflow control55. Refer to the exhibit. Which path will traffic from the 172.16.1.0/24network take to get to the 10.0.0.0/24 network?ADCABCIt will load balance the traffic between ADC and ABCIt will send the traffic via ABC, and will use ADC as a backup path only when ABCfails.56.
Refer to the exhibit. Routers 1 and 2 are directly connected over a seriallink. Pings are failing between the two routers. What change by theadministrator will correct the problem?Set the encapsulation on both routers to PPP.Decrease the bandwidth on Serial 0/1/0 on router 2 to 1544.Change the cable that connects the routers to a crossover cable.Change the IP address on Serial 0/1/0 on router 2 to 192.168.0.1/30.Стр. 12 из 2701.04.2009 0:45CISCO CCNA Certifications: CCNA 2 UPDATEDfile:///D:/botalka/%D1%81%D0%B8%D1%81%D1%8C%D0%BA...57. Which two statements are true regarding link-state routing protocols?(Choose two.)They do not work well in networks that require special heirarchical designs.They are aware of the complete network topology.They pass their entire routing tables to their directly connected neighbors only.They offer rapid convergence times in large networks.They rely on decreasing hop counts to determine the best path.They do not include subnet masks in their routing updates.58.
Which three statements about routing protocols are true? (Choosethree.)OSPF elects designated routers on multiaccess links.RIP does not support classless routing.EIGRP supports unequal cost load balancing.EIGRP uses broadcast traffic to establish adjacencies with its neighbors.RIP does not advertise a route beyond a hop count of 15.OSPF can convergence more quickly because it can find a feasible successor in itstopology table when a successor route goes down.comments (0)TOP05:21CCNA 2:Module 11POSTED BY ADMIN1. Refer to the exhibit. What does the "O*E2" from the "O*E2 0.0.0.0/0[110/1] via 192.168.1.1, 00:05:34, Serial0/0" line represent?an external OSPF route that will not increment in cost.2.

What does OSPF use to calculate the cost to a destination network?bandwidth6. A fully converged five router OSPF network has been running successfullyfor several weeks. All configurations have been saved and no static routesare used.
If one router looses power and reboots, what information will bein its routing table after the configuration file is loaded but before OSPF hasconverged?Routes for connected networks that are operational will be in the routing table.7. Refer to the exhibit. Router A is correctly configured for OSPF. WhichOSPF configuration statement or set of statements was entered for router Bto generate the exhibited routing table?B(config-router)# network 192.168.1.0 0.0.0.3 area 08. Refer to the exhibit.
