In the global configuration mode, the router continues to display itshost name followed by (config) and the # symbol:RouterA#configure terminalRouterA(config)#The global configuration mode is where you can make "global" changes to theconfiguration of the router. A common example of a global configuration is the creationof an access list.
From the global configuration mode, you can move to a position thatenables you to configure specific components of the router, such as the router interfaces;virtual private network (VPN) components (isakmp, crypto, and so on); CLI connections(line); authentication, authorization, and accounting (AAA) server groups; and manymore. To exit to the privileged global configuration mode, use the key combinationCtrl-Z or type the command "end."Actualtests.com - The Power of Knowing640-802QUESTION 393:You need to configure a new Cisco router for remote access on the Certkillernetwork.
How many simultaneous telnet sessions does this Cisco router support bydefault?A. 4B. 2C. 5D. 1E. 6F. 0Answer: CExplanation:Telnet sessions use virtual terminal sessions, which are configured under the "line vty"portion of the configuration. There are 5 total vty sessions that can be configured,numbered 0-4.QUESTION 394:SIMULATIONActualtests.com - The Power of Knowing640-802You work as a network engineer at Certkiller .com.You are required to set up the Certkiller network.There are two separate tasks.Task 1:First you need to make the following placements:* place a router or switch at each device spot* place a connection type at each connections spot* place an IP address at each IP spotTask 2:Configure each, if any, additional router as follows:* each additional interface should have the correct IP address and be enabled* set the password to allow console access to password1* set the password to allow telnet access to password2* set the password to allow privilege mode access to password3Note.

show interfacesB. show processesC. show running-configD. show versionsE. show startup-configAnswer: AActualtests.com - The Power of Knowing640-802Explanation:Use the show interfaces EXEC command to display statistics for all interfacesconfigured on the router or access server. The resulting output varies, depending on thenetwork for which an interface has been configured.The following is an example from theshow interfaces command. Because your displaywill depend on the type and number of interface cards in your router or access server,only a portion of the display is shown.CK1 #showinterfacesEthernet0isup,lineprotocolisupHardwareisMCIEthernet,addressis0000.0c00.750c(bia0000.0c00.750c)Internetaddressis131.108.28.8,subnetmaskis255.255.255.0MTU1500bytes,BW10000Kbit,DLY100000usec,rely255/255,load1/255EncapsulationARPA,loopbacknotset,keepaliveset(10sec)ARPtype:ARPA,ARPTimeout4:00:00Lastinput0:00:00,output0:00:00,outputhangneverLastclearingof"showinterface"counters0:00:00Outputqueue0/40,0drops;inputqueue0/75,0dropsFiveminuteinputrate0bits/sec,0packets/secFiveminuteoutputrate2000bits/sec,4packets/sec1127576packetsinput,447251251bytes,0nobufferReceived354125broadcasts,0runts,0giants,57186*throttles0inputerrors,0CRC,0frame,0overrun,0ignored,0abort5332142packetsoutput,496316039bytes,0underruns0outputerrors,432collisions,0interfaceresets,0restartsReference:http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/inter_r/irshowin.htmQUESTION 398:The following was seen on a Certkiller router in Huntsville:Actualtests.com - The Power of Knowing640-802Refer to the router output shown in the graphic.
What can be assumed about thenetwork attached to this router interface?A. The network hosts are attached to a hub.B. The interface is being used at near maximum capacity.C. There should never be any collisions in this network.D. The network has an excessive number of errors.E. The network is using an unusual Ethernet encapsulation.Answer: CExplanation:Based on the output shown, this interface is configured to operate in full duplex mode.Full-duplex is a data communications term that refers to the ability to send and receivedata at the same time.Legacy Ethernet is half-duplex, meaning information can move in only one direction at atime.
In a totally switched network, nodes only communicate with the switch and neverdirectly with each other. Switched networks also employ either twisted pair or fiber opticcabling, both of which use separate conductors for sending and receiving data. In thistype of environment, Ethernet stations can forgo the collision detection process andtransmit at will, since they are the only potential devices that can access the medium.This allows end stations to transmit to the switch at the same time that the switchtransmits to them, achieving a collision-free environment.Reference: http://computer.howstuffworks.com/ethernet15.htmActualtests.com - The Power of Knowing640-802QUESTION 399:Refer to the output of the three Certkiller router commands shown in the exhibit.
Anew technician has been told to add a new LAN to the company router. Why has thetechnician received the error message that is shown following the last command?A. The command was entered from the wrong prompt.B. The router does not support LAN interfaces that use Ethernet.C. The interface was already configured.D. The IOS software loaded on the router is outdated.E.
The interface type does not exist on this router platform.F. None of the aboveAnswer: EExplanation:The show version command displays the information regarding version of IOS, name ofIOS image, configuration register as well all interface name of router. According to theoutput of show version, there is no ethernet interface so trying to configure the invalidinterface.
What the technician needs to enter is "interface fastethernet 0" not "ethernet 0".Actualtests.com - The Power of Knowing640-802QUESTION 400:In the Certkiller router below, serial0/0 does not respond to a ping request from ahost on the FastEthernet0/0 LAN. How can this problem be corrected?A. Correct the IP address for Serial 0/0.B. Change the encapsulation type on Serial 0/0.C. Correct the IP address for FastEthernet 0/0.D. Enable autoconfiguration on the Serial 0/0 interface.E.
Enable the Serial 0/0 interface.Answer: EExplanation:The status of the interface shows "administratively down" which means that the interfacewas manually shut down, or it was never enabled in the first place. This interface needsto be enabled using the "no shutdown" command under interface serial 0/0 in theconfiguration.QUESTION 401:An administrator issues the show ip interface s0/0 command and the output displaysthat interface Serial0/0 is up, line protocol is upWhat does "line protocol is up" specifically indicate about the interface?A. The cable is attached properly.B.
CDP has discovered the connected device.C. Keepalives are being received on the interface.D. A carrier detect signal has been received from the connected device.E. IP is correctly configured on the interface.Answer: CActualtests.com - The Power of Knowing640-802Explanation:Serial 0/0 is up, line protocol is up is the proper status line condition.Line serial0/0 is up: This statement represents that the physical connection is good.Line protocol is up: This represents that the data link layer is OK, meaning that layer 2keepalives are being received on the interface.When the line protocol goes down, a possible problem is keep-alives not being sent byremote router.QUESTION 402:You need to configure the interfaces on a new Certkiller router, but first you need toenter the global configuration mode.
Which command is used on router Certkiller 3to reach this mode?A. Certkiller 3# routerB. Certkiller 3# setupC. Certkiller 3# interfaceD. Certkiller 3> enableE. Certkiller 3# configure terminalAnswer: EExplanation:Global configuration mode is the mode that allows you to configure the router and ittakes effect immediately. You can enter into the global configuration mode using"configure terminal" command.Interface configuration mode allows you to configure the interface on a particularinterface such as setting the IP address, setting bandwidth, clock rate, encapsulation type,duplex, speed, etc. Use the "interface interface-name" command to enter into theinterface configuration mode.QUESTION 403:Network Topology Exhibit:Configuration and output exhibit:Actualtests.com - The Power of Knowing640-802You work as a network technician at Certkiller .com.
Study the exhibit carefully. Atechnician is troubleshooting a host connectivity problem. The host is unable to pinga server connected to Switch CertkillerA. Based on the result of the testing, whatcould be the problem?A. TCP/IP has not been correctly installed on the hostB. A local physical layer problem existsC. The host NIC is not functioningD. A remote physical layer problem existsE. None of the aboveAnswer: BQUESTION 404:The following output was seen on a Certkiller device:Actualtests.com - The Power of Knowing640-802Study the exhibit above carefully.
