Which routing protocol by default uses bandwidthand delay to calculate the metric of a route?RIPv1RIPv2OSPFEIGRP43. Two routers need to be configured within a singlehttp://cisco-ccna-certifications.blogspot.com/2008/08/ccna-2final-set-3.html[10/29/2008 4:06:03 PM]CISCO CCNA Certifications: CCNA 2:Final Set 3OSPFarea.Whichtwocomponentsneedto beconfigured on both routers to achieve this? (Choosetwo.)the same process IDthe same area IDnetwork addresses and wildcard masksthe same router IDthe same loop back address44.Refertotheexhibit.Thenetworksthat areconnected to R1 have been summarized for R2 as192.168.136.0/21.
Which packet destination addresswill R2 forward to R1?192.168.135.1192.168.142.1192.168.144.1192.168.128.145. Refer to the exhibit. R1 is running RIP with defaultparameters. R1 has learned four different paths withthe same metrics to network 192.168.6.0. Which pathor paths will R1 use to forward a packet that isdestined to 192.168.6.10?the first path that the router learned.only the first two of the four paths that the router learned.the last path that the router learned.all four paths.46.
What are two functions of a router? (Choose two.)It connects multiple IP networks.It controls the flow of data via the use of Layer 2 addresses.It determines the best path to send packets.It manages the VLAN database.It increases the size of the broadcast domain.47. Refer to the exhibit. Which statement is true aboutthe routing process for this network?A packet leaves interface Fa0/0 of R1 with the source MACaddress as 000C.3010.9260.The packet leaves interface Fa0/0 of R1 with the source MACaddress as 000C.3010.9260.The no shutdown command needs to run on the Fa0/0interface of R1.The Fa0/0 interface of R2 could be configured with the IPaddress 172.16.4.1/24.48.
Refer to the exhibit. A network administrator hasrun the show interface command. The output of thiscommand is displayed. What is the first step that isrequired to make this interface operational?http://cisco-ccna-certifications.blogspot.com/2008/08/ccna-2final-set-3.html[10/29/2008 4:06:03 PM]CISCO CCNA Certifications: CCNA 2:Final Set 3Switch the cable with a known working cable.Issue the no shutdown command on the interface.Configure the interface as a loopback interface.Set the encapsulation for the interface.49. Refer to the exhibit.
R1 is configured properly for asingle area OSPF, and R2 has been recently installed inthe network. Which set of commands is required toconfigure a single area OSPF for the networks that areconnected to R2?R2(config)# router ospf 1R2(config-router)# network 192.168.2.0 0.0.0.255 area 0R2(config-router)# network 10.1.1.0 0.0.0.3 area 0R2(config)# router ospf 1R2(config-router)# network 192.168.2.0 0.0.0.255 area 0R2(config)# router ospf 2R2(config-router)# network 10.1.1.0 0.0.0.3 area 0R2(config)# router ospf 1R2(config-router)# network 192.168.2.0 0.0.0.255 area 0R2(config-router)# network 10.1.1.0 0.0.0.3 area 1R2(config)# router ospf 1R2(config-router)# network 192.168.2.0 0.0.0.255 area 0R2(config-router)# network 10.0.0.0 0.0.0.3 area 150.
Refer to the exhibit. The command ip route 0.0.0.00.0.0.0 S0/0/0 is run on router R2. What are the tworesults of this command? (Choose two.)A static route will be updated in the routing table.The traffic from the Internet will be directed to R2.The traffic from the source network 172.16.0.0/22 will beblocked.The route will be specified as the default route for allnetworks not defined in the routing table.All the broadcasts will be forwarded via the S0/0/0 interfaceof R2.51. Which three statements are true regarding theencapsulation and de-encapsulation of packets whentraveling through a router? (Choose three.)The router modifies the TTL field, decrementing it by one.The router changes the source IP to the IP of the exitinterface.The router maintains the same source and destination IP.The router changes the source physical address to thephysical address of the exit interface.The router changes the destination IP to the IP of the exitinterface.The router sends the packet out all other interfaces, besidesthe one it entered the router on.52.
What are two tasks that must be completed beforehttp://cisco-ccna-certifications.blogspot.com/2008/08/ccna-2final-set-3.html[10/29/2008 4:06:03 PM]CISCO CCNA Certifications: CCNA 2:Final Set 3tworouterscanuseOSPFtoformaneighboradjacency? (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.53. Refer to the exhibit. Although both the routers canping the serial interface of their neighbors, they areunable to ping the Ethernet interfaces of other routers.Which two statements are true for this network?(Choose two.)The administrative distance has been set to 50 on bothrouters.R2 is learning about network 192.168.1.0.R1 is learning about network 192.168.2.0.The network 10.1.1.0 command has not been run on bothrouters.Autosummarization is enabled on both routers.54.
Which two situations require the use of a link-stateprotocol? (Choose two.)Fast convergence of the network is critical.The network is very large.Thenetworkadministratorhaslimitedknowledgetoconfigure and troubleshoot routing protocols.The network is a flat network.The capacity of the router is low.55. Refer to the exhibit. What information can bedetermined from the displayed output?EIGRP packets are waiting to be sent to the neighbors.Theadjacenciesbetweentheroutersareyettobeestablished.TheIPaddress192.168.10.10isconfiguredat serialinterface S0/0/1 of router R2.Router R2 is receiving hello packets from a neighbor withthe IP address 192.168.10.10 via the R2 S0/0/1 interface.56. Refer to the exhibit.
PC1 is unable to access theInternet. What is the cause of the problem?An incorrect IP address is configured between the tworouters.No static route is configured on Router2.A routing loop has occurred.No routing protocol is configured on either of the tworouters.57. Refer to the exhibit. What summarization should R2use to advertise its LAN networks to R1?172.16.0.0/24http://cisco-ccna-certifications.blogspot.com/2008/08/ccna-2final-set-3.html[10/29/2008 4:06:03 PM]CISCO CCNA Certifications: CCNA 2:Final Set 3172.16.4.0/22172.16.4.0/23172.16.4.0/24POSTED BY SNOWANGEL AT 05:24LABELS: CCNA 2 UPDATED0 COMMENTS:Post a CommentNewer PostHomeOlder PostSubscribe to: Post Comments (Atom)http://cisco-ccna-certifications.blogspot.com/2008/08/ccna-2final-set-3.html[10/29/2008 4:06:03 PM].
