Change the bandwidth setting on Certkiller 1 to match the actual line speed.D. Verify successful DCE communication between the two sites.E. Verify Layer 1 communication on the Certkiller 1 Serial 0/ interface.Answer: BEncapsulation:The High Level Data Link Control protocol (HDLC) is the default encapsulation used onthe synchronous serial interfaces of a Cisco router.Because of the proprietary nature of vendor HDLC implementations, you should only useHDLC framing on point-to-point links when the router at each end of a link is from thesame vendor. In cases where you want to connect equipment from different vendors overa leased line, the Point-to-Point Protocol (PPP) should be used. Always remember thatthe router on both sides of a point-to-point link must be using the same data framingActualtests.com - The Power of Knowing640-802method in order to communicate.Reference: http://www.2000trainers.com/cisco-ccna-11/ccna-hdlc/QUESTION 750:Exhibit #1:Exhibit #2:You work as a network administrator at Certkiller .com.
You study the exhibitscarefully. What is the most likely reason for disparity between the actual networknumbers at the branches and the routes in the routing table on Certkiller 0?A. Certkiller 1 is configured to only send RIPv1 updates.B. Certkiller 0 is configured to receive only RIPv1 updates.C. Certkiller 2 is configured to send both RIPv1 and RIPv2 updates.D. Certkiller 0 is configured to only receive RIPv2 updates.E.
None of the aboveAnswer: AExplanation:The default version of RIP is version 1, which doesn't supports multicast updates,classless networks, and authentication. It appears that Certkiller 1 router is configured withRIP v1 so it's sending only v1 packets, which means only the classful network of208.149.23.0/24 is being advertised. However, it appears that Certkiller 2 is indeed usingRIPv2 as both the /27 networks are being advertised from that router.If you wish to enable to RIP version 2 on router use following command:Router(Config)#router ripRouter(Config-router)#version 2Actualtests.com - The Power of Knowing640-802QUESTION 751:A receiving host on the Certkiller network named CK1 computes the checksum on aframe and determines that the frame is damaged.
The frame is then discarded. Atwhich OSI layer did this happen?A. ApplicationB. PresentationC. SessionD. TransportE. InternetF. Data LinkG. PhysicalAnswer: FExplanation:The Data Link layer provides the physical transmission of the data and handles errornotification, network topology, and flow control. The Data Link layer formats themessage into pieces, each called a data frame, and adds a customized header containingthe hardware destination and source address. Protocols Data Unit (PDU) on Datalinklayer is called frame. According to this question the frame is damaged and discardedwhich will happen at the Data Link layer.QUESTION 752:Exhibit:You need to troubleshoot an issue on the Certkiller network.
Based on the outputshown in the exhibit, what is the reason that the interface status shows"administratively down, line protocol down"?A. The wrong type of cable is connected to the interface.B. There is no encapsulation type configured.C. The interface needs to be configured as a DTE deviceD. There is a mismatch in encapsulation types.E. The interface has been configured with the shutdown command.F.
The interface is not receiving any keepalives.G. None of the aboveAnswer: EExplanation:Actualtests.com - The Power of Knowing640-802To be an effective troubleshooter, you have to know how things look when all is well, notjust when something is broken! When an interface is functioning correctly, this is whatwe see at the top of the show interface output. I'll use Serial0 for all examples in thissection.Example1: Normal operational status:Router1#show int serial0Serial0 is up, line protocol is upExample2: Interface is administratively down:CK1 #show int serial0Serial0 is administratively down, line protocol is downAdministratively down means the interface is indeed shut down using the "shutdown"interface command. Open the interface with no shutdown.CK1 (config)#int serial0Router1(config-if)#no shutdownAlways wait a minute or so to come up after enabling a serial interface.CK1 #show interface serial0Serial0 is up, line protocol is upQUESTION 753:Exhibit:In the Certkiller switched, network you are unable to connect remotely to switchCertkiller 5.
You initiatea console session and execute the "show ip interface brief"command as shown. Why did the remote connection fail?A. The switch does not have a management IP address assigned.B. The Gigabit Ethernet interfaces are not up.C. VLAN1 is shut down.D. The switch needs to have a clock rate entered on one of its interfaces.E. None of the aboveAnswer: CExplanation:The virtual LAN Interface can be enabled or disabled with shutdown/no shutdownActualtests.com - The Power of Knowing640-802command. If you interface is down, it will display administratively down status.
You canbring up an interface having administratively down interface using no shutdowncommand. Since the only IP configured on the switch belongs to VLAN 1, it needs to beenabled for you to remotely access the device.QUESTION 754:DRAG DROPYou work as a network administrator at Certkiller .com.
Your boss, Mrs. Certkiller,is interested in network user applications. Match the application with the properapplications.Actualtests.com - The Power of Knowing640-802Answer:QUESTION 755:Exhibit #1:Exhibit #2:Actualtests.com - The Power of Knowing640-802You work as a network administrator at Certkiller .com. You study the exhibitscarefully. On an external router Certkiller 3, the network administrator enters theMOTD configuration that is shown in the upper box.
You then log into Certkiller 3router and see the login screen dialg that is shown in the lower box.Why does the intended message not display?A. The banner message exceeds the number of characters allowed.B. The network administrator defined an illegal delimiting character int eh MOTDcommand.C. The MOTD delimiting character appeared in the body of the text.D. MOTD banner text may contain only letters and numbers.E. The IOS image on this router does not support the MOTD configuration shown.F.
None of the aboveAnswer: CExplanation:The banner is displayed whenever anyone logs in to your Cisco router. The syntax is"banner motd # " . MOTD stands for "Message Of The Day".# symbol signifies the start of the banner message to the router. You will be prompted forthe message to be displayed. You need to enter "#" symbol at the end of the message,signifying that the msg has ended. In this case, the # was included in the body of themessage, but the router considers it to be the end of the message so only the textpreceding the "#" will be displayed.QUESTION 756:Exhibit:You are evaluating the efficiency of the current Certkiller network.
RIPv2 is enabledon all Layer 3 devices in the network. In this network, which devices participate inpassing traffic from the PC at 10.10.1.7 to File Server Certkiller A at 10.20.1.6 in theorder that they will forward traffic from source to destination?Actualtests.com - The Power of Knowing640-802A. Switch Certkiller 3, Router Certkiller 1, Router Certkiller 2, Switch Certkiller Certkiller 4B. Switch Certkiller 3, Router Certkiller 1, Switch Certkiller 3, Switch Certkiller Certkiller 4C. Switch Certkiller 3, Switch Certkiller Certkiller 4, Router Certkiller 2, Switch Certkiller 4D.
Switch Certkiller 3, Switch Certkiller Certkiller 4E. None of the aboveAnswer: AExplanation:When data traffic is sent from the PC having the 10.10.1.7 IP address to the PC with10.20.1.6 it goes through Switch Certkiller 3, Router Certkiller 1, Router Certkiller 2,Switch Certkiller Certkiller 4. Since the PC and server reside on different IP subnets trafficwill need to go through a router.The gateway IP address of PC 10.10.1.7 is the router Certkiller 1's Ethernet IP.
So whensending the data it goes to gateway through Certkiller 3 switch. When packet reached toCertkiller 1 router it forwards to the Certkiller 2 router based on the routing table. Finally,router Certkiller 2 forwards the packets to the Certkiller 4 switch.QUESTION 757:What is the purpose of an Address Resolution Protocol (ARP) request message?A. It creates a session by passing a header with destination Layer 2 address to thetransport layer.B. It binds the IP address of a host to the network that it is on.C.
