Refer to the exhibit. All router interfaces areconfigured with an IP address and are operational. Ifno routing protocols or static routes are configured,what information will be included in the show ip routecommand output for router A?All of the 192.168.x.0 networks will be in the routing table.http://cisco-ccna-certifications.blogspot.com/2008/08/ccna-2final-set-2.html[10/29/2008 4:04:06 PM]CISCO CCNA Certifications: CCNA 2:Final Set 2Routes to networks 192.168.1.0/24, 192.168.2.0/24, and192.168.3.0/24 will be in the routing table.The routing table will be empty because routes and dynamicroutes have not been configured.A default route is automatically installed in the routing tableto allow connectivity between the networks.39. Refer to the exhibit.
How many routes are bothlevel 1 and qualify for use as an ultimate route?12345640. When presented with multiple valid routes to adestination,whatcriteriadoesarouteruse todetermine which routes to add to the routing table?The router selects the routes with the best metric. All routesthat have the same best metric are added to the routingtable.The router first selects routes with the lowest administrativedistance. The resulting routes are then prioritized by metricand the routes with the best metric are added to the routingtable.The router selects the routes with the lowest administrativedistance.
All routes with the same lowest administrativedistance are added to the routing table.The router installs all routes in the routing table but usesthe route with the best metric most when load balancing.41. Refer to the exhibit.

Refer to the exhibit. Hosts on the BOS Fa0/0 LANare able to ping the Fa0/1 interface on the JAX routerand all interfaces on the BOS and ORL routers. Whywould hosts from the 10.0.0.0/24 network not be ableto ping hosts 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 0command.The JAX router needs the network 192.168.3.0 0.0.0.255area 0 command.The BOS router needs the network 192.168.3.0 0.0.0.255area 0 command.44. What command would the network administratorapply to a router that is running OSPF to advertise theentire range of addresses included in 172.16.0.0/19 inarea 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 beforetworouterscanuseOSPFtoformaneighboradjacency? (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.The routers must exchange database description packets.46. Refer to the exhibit.
Which statement is trueconcerning the routing configuration?Using dynamic routing instead of static routing would haverequired fewer configuration steps.The10.1.1.0/24and10.1.2.0/24routeshave adjacentboudaries and should be summarized.The static route will not work correctly.Packets routed to the R2 ethernet interface require tworouting table lookups.47. What can be determined from the output shown inthe exhibit? (Choose two.)Annapolis is a 2611 router that is connected to the S0/0interface of the Montgomery router.All of the routers are connected to Montgomery through anEthernet switch.http://cisco-ccna-certifications.blogspot.com/2008/08/ccna-2final-set-2.html[10/29/2008 4:04:06 PM]CISCO CCNA Certifications: CCNA 2:Final Set 2Montgomery has Layer 2 connectivity with Cumberland.Layer 3 connectivity is operational for all of the deviceslisted in the Device ID column.An administrator consoled into the Waldorf router can pingthe Brant router.Brant, Fisherman, and Potomac are directly connected toMontgomery.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 OSPFroutersused to request more information about any entry in theBDRused to announce new OSPF information and to reply tocertain types of requests50. Refer to the exhibit. All routers in the network arerunning RIPv2 and EIGRP with default routing protocolsettingsandhaveinterfacesconfiguredwiththebandwidths that are shown in the exhibit. Whichprotocol will be used and how will traffic between theRouter1 LAN and Router5 LAN be routed through thenetwork?RIPv2 will load balance across both paths between Router1and Router5.EIGRP will load balance across both paths between Router1and Router5.RIPv2 traffic will use the path Router1, Router2, Router5because it has the least hops.EIGRP traffic will use the path Router1, Router3, Router4,Router5 because it has the best metric.51.
Refer to the exhibit. A network administrator istrying to figure out why BOS does not have the10.0.0.0/24 network in its routing table. All routers areconfigured for OSPF in area 0. The links between therouters are operational and the administrator is able toping between all router interfaces. What is a logicalnext step that the network administrator should take totroubleshoot 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 therouters.Use show and debug commands to determine if hellos arepropagating.52.
Refer to the exhibit. The network is using the RIPv2routing protocol.

Which two router component and operation pair arecorrectly described? (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 arouter? (Choose two.)packet switchingmicrosegmentationdomain name resolutionpath selectionflow control55.
Refer to the exhibit. Which path will traffic from the172.16.1.0/24 network take to get to the 10.0.0.0/24network?ADCABCIt will load balance the traffic between ADC and ABCIt will send the traffic via ABC, and will use ADC as a backuppath only when ABC fails.56. Refer to the exhibit. Routers 1 and 2 are directlyconnected over a serial link. Pings are failing betweenthe two routers.
What change by the administrator willcorrect the problem?Set the encapsulation on both routers to PPP.Decrease the bandwidth on Serial 0/1/0 on router 2 to1544.Change the cable that connects the routers to a crossovercable.Change the IP address on Serial 0/1/0 on router 2 to192.168.0.1/30.57. Which two statements are true regarding link-staterouting protocols? (Choose two.)They do not work well in networks that require specialhttp://cisco-ccna-certifications.blogspot.com/2008/08/ccna-2final-set-2.html[10/29/2008 4:04:06 PM]CISCO CCNA Certifications: CCNA 2:Final Set 2heirarchical designs.They are aware of the complete network topology.They pass their entire routing tables to their directlyconnected neighbors only.They offer rapid convergence times in large networks.They rely on decreasing hop counts to determine the bestpath.They do not include subnet masks in their routing updates.58. Which three statements about routing protocols aretrue? (Choose three.)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 itsneighbors.RIP does not advertise a route beyond a hop count of 15.OSPF can convergence more quickly because it can find afeasible successor in its topology table when a successorroute goes down.POSTED BY SNOWANGEL AT 05:22LABELS: CCNA 2 UPDATED0 COMMENTS:Post a CommentNewer PostHomeOlder PostSubscribe to: Post Comments (Atom)http://cisco-ccna-certifications.blogspot.com/2008/08/ccna-2final-set-2.html[10/29/2008 4:04:06 PM].
