During this state, no new path will be accepted for the same destinationfor this amount of time. The hold time indicates how long this state should last.Incorrect Answers:A, C, D, F. Although these are all features and functions of RIP version 2, they are notmechanisms used to prevent routing loops.G. Path Vectoring is a concept used by BGP routers. RIP version 1 and 2 are consideredto be distance vector routing protocols.QUESTION 382:Refer to the following Certkiller network:Actualtests.com - The Power of Knowing640-802S0/0 on CK1 is configured as a multipoint interface to communicate with CK2 andCK3 in the hub-and-spoke Frame Relay topology shown in the exhibit. Originally,static routes were configured between these routers to successfully route trafficbetween the attached networks. What will need to be done in order to use RIP v2 inplace of the static routes?A.
Configure the no ip subnet-zero command on CK1 , CK2 , and CK3 .B. Dynamic routing protocols such as RIP v2 cannot be used across Frame Relaynetworks.C. Configure the s0/0 interface on CK1 as two subinterfaces and configure point-to-pointlinks to CK2 and CK3 .D.
Change the 172.16.2.0/25 and 172.16.2.128/25 subnetworks so that at least two bitsare borrowed from the last octet.E. Change the network address configurations to eliminate the discontiguous172.16.2.0/25 and 172.16.2.128/25 subnetworks.Answer: CExplanation:For Dynamic Routing in Hub-and spoke topology, configure the subinterface for eachlink then define the link as point to point. One reason for the use of subinterfaces is tocircumvent the rule of split horizon. Split horizon dictates that a route cannot beadvertised out the same interface upon which it was learned in the first place.
This can bea problem in hub and spoke frame relay networks, but by using pt-pt subinterfaces thisproblem will be eliminated.QUESTION 383:The following output was shown on router CK1 :Based on the information shown above, what can be determined from the line ofshow ip route output shown in the exhibit? (Choose two)A. The 10.10.10.8 network is two hops away from this router.B.
The next routing update can be expected in 35 seconds.C. The IP address 10.10.10.6 is configured on S0/1.D. The IP address 10.10.10.8 is configured on S0/1.E. This route is using the default administrative distance.Answer: A, EExplanation:Actualtests.com - The Power of Knowing640-802When issuing the "show ip route" command, the first number in the brackets is theadministrative distance of the information source; the second number is the metric for theroute.
In this case, the value of 120 is the default AD for RIP routes, and the 2 representsthe metric, which is the number of router hops in RIP. The 10.10.10.6 IP address belongsto the neighboring router (not the local router) that sent the update in via Serial 0/1.QUESTION 384:SIMULATIONNetwork topology exhibit:You work as a network technician at Certkiller.com. Study the network topologyexhibit carefully. You are stationed at the Rome office of Certkiller .com. You haveupgraded the Rome LAN by adding the Certkiller 3 router to the network.

Connect the PC's COM port to the router's console port using a straight-through cable.B. Connect the PC's COM port to the router's console port using a crossover cable.C. Connect the PC's COM port to the router's Ethernet port using a straight-throughcable.D. Connect the PC's Ethernet port to the router's Ethernet port using a crossover cable.E. Connect the PC's Ethernet port to the router's Ethernet port using a rollover cable.F.
Connect the PC's Ethernet port to the router's Ethernet port using a straight-throughcable.G. None of the aboveAnswer: DExplanation:A crossover cable is used to directly connect a switch to a switch, a hub to a hub, a hostto a host, or a host's Ethernet port to a router's Ethernet interface. If your Router'sinterface is configured with IP addressing and telnet service is enabled you can logthrough the telnet program into your router.Incorrect Answers:A, B, C: The COM port is used for direct terminal connections to a router, via the use ofterminal emulation programs such as HyperTerminal.E: A rollover cable is used to connect via a console connection.F: A straight through cable would be used if there was a LAN switch or a hub in place,but when connecting to the router directly from a PC a cross over cable should be used.QUESTION 389:You are given a PC, a router, and a cable.
Select the correct combination that willallow you to log into router CK1 locally using a terminal emulation program such asHyperTerminal.A. Connect the PC's COM port to the router's console port using a straight-through cable.B. Connect the PC's COM port to the router's console port using a rollover cable.C. Connect the PC's COM port to the router's Ethernet port using a straight-throughcable.Actualtests.com - The Power of Knowing640-802D. Connect the PC's Ethernet port to the router's Ethernet port using a rollover cable.E.
Connect the PC's Ethernet port to the router's Ethernet port using a straight- throughcable.F. None of the aboveAnswer: BExplanation:To connect the Router in Console port to configure using HyperTerminal, you requiredthe Rollover Cable, which connects the PC's COM port to the router's Console port.Incorrect Answers:A, C, E: Straight Cables are used for: Host to switch, Switch to Router.D: Rollover cables are used for Console/COM connections, not for IP traffic over theEthernet ports.QUESTION 390:Which router console commands shown below are used to manage telnet sessions toother routers? (Select three)A.
Certkiller D# disconnect 3B. Certkiller D# exit session 2C. Certkiller D# kill connection 1D. Certkiller D# show sessionsE. Certkiller D# show connection allF. Certkiller D# resume 4Answer: A, D, FExplanation:Actualtests.com - The Power of Knowing640-802Reference: Cisco Press CCNA Study Guide, p.392QUESTION 391:Part of the configuration of router CK1 is shown below:What is the effect of the configuration shown above on router CK1 ?A. It configures SSH globally for all logins.B. It tells the router or switch to try to establish an SSH connection first and if that failsto use Telnet.C. It configures the virtual terminal lines with the password 030752180500.D. It configures a Cisco network device to use the SSH protocol on incomingcommunications via the virtual terminal ports.E.
It allows seven failed login attempts before the VTY lines are temporarily shutdown.F. None of the above.Actualtests.com - The Power of Knowing640-802Answer: DExplanation:Secure Shell (SSH) is a protocol which provides a secure remote access connection tonetwork devices. Communication between the client and server is encrypted in both SSHversion 1 and SSH version 2. If you want to prevent non-SSH connections, add the"transport input ssh" command under the lines to limit the router to SSH connectionsonly. Straight (non-SSH) Telnets are refused.Reference: www.cisco.com/warp/public/707/ssh.shtmlQUESTION 392:You need to make changes to a new Certkiller router. By which prompt is the globalconfiguration mode on this router identified?A.
Router(config-line)#B. Router(config-router)#C. Router#D. Router(config)#E. Router>F. Router(config-if)#G. None of the aboveAnswer: DExplanation:There are many different configuration modes. Each of these makes changes to thedevice configuration. To ensure that those configuration changes are not lost if the routerreboots, you must copy the running configuration to the startup configuration. The typeand number of configuration submodes depends on the type of router, the Cisco IOSversion, and the components installed on the router:- Global configuration mode- The command for accessing the global configuration modeis configure terminal.
