The administrator's workstation must be on the same subnet as the router E0 interface.F. The Ethernet connection between the router and the administrator's workstation mustbe via straight-through cable.Answer: B, D, EExplanation:The sole purpose of the 'copy flash tftp' command is to copy the routers configuration fileto the TFTP server to save it. The first logical variable for this operation is that the TFTPsoftware is actually running. So B is correct. D is correct because the IOS won't be ableto send off if it doesn't even know where the TFTP server is. Finally, TFTP server mustbe on the same subnet as the connectivity must be direct and the TFTP and router willneed to know how to reach each other.Incorrect Answer:A.
The TFTP can't just be activated, it has to be running in the right place.C. This is not valid because you aren't downloading into the flash, you're uploading outof the flash, so space isn't a concern.F. A cross over cable must be used when connecting from a PC directly into the router'sEthernet interface.Actualtests.com - The Power of Knowing640-802QUESTION 444:What kind of information can you deduce from an IOS image file name? (Selectthree answer choices)A. Distribution channel failuresB. Feature capabilitiesC. Memory capacity needsD.
Hardware product platformE. Programming language requirementsF. Run location and compression statusAnswer: B, D, FExplanation:Image Naming Conventions:You can identify the platform, features, and image location by the name ofthe image. The naming convention is platform-features-type for images thatare stored on a UNIX system.The platform variable indicates which platforms can use this image. Examplesof platform variables include rsp (Cisco 7000 series with RSP7000 and Cisco7500 series), c1600 (Cisco 1600 series), and c1005 (Cisco 1005).The features variable identifies the feature sets supported by the image.The type field can contain the following characters:f-The image runs from Flash memory.m-The image runs from RAM.r-The image runs from ROM.l-The image is relocatable.z-The image is zip compressed.x-The image is mzip compressed.QUESTION 445:You wish to upgrade the IOS of a router without removing the image currentlyinstalled.What command will display the amount of memory that is being used by thecurrent IOS image and whether there is enough room available to hold both thecurrent and new images?A.
Router# show versionB. Router# show flashC. Router# show memoryD. Router# show buffersE. Router# show running-configActualtests.com - The Power of Knowing640-802F. All of the aboveAnswer: BExplanation:The "show flash" command is used to display the layout and contents of the flashmemory file system. It will show name of the file system, as well as the number of bytesused and the number available within the flash memory.QUESTION 446:The "show version" command was issued on a Certkiller router as shown below:The Network administrator at Certkiller .com wants to upgrade the IOS of thisrouter.
The new Image requires 64 MB of RAM & 16 MB for Storage of the File.Given the Output Shown in the Graphic, which of the following is true?A. This router meets the requirements for the new image.B. This router will require a DRAM upgrade to meet the requirements for the Image.C. This router will require a FLASH upgrade to meet the requirements for the Image.D.
This router will require a NVRAM upgrade to meet the requirements for the Image.Answer: BExplanation:Based on the output above, the router above will not require a Flash memory upgrade, asonly 16 MB is required and the Certkiller router does indeed have 16 MB of flash (16384bytes). However, a DRAM upgrade is required, as 64 MB of RAM is needed but thisrouter has only slightly more than 16 MB as shown by the 16384/2048 value.Actualtests.com - The Power of Knowing640-802QUESTION 447:You are a trainee technician at Certkiller , Inc.
Your instructor tells you to backupan IOS image of a Cisco device to a Windows 2003 server on the network.What should you do first? (Choose three)A. Make sure that the network server can be accessed.B. Check that the authentication for access is set.C. Assure that the network server has adequate space for the code image.D. Verify any file naming and path requirements.E.
Make sure that the server can load and run the bootstrap code.Answer: A, C, DExplanation:In order to properly back up the Cisco IOS image onto a Windows server, you shouldensure that the server is reachable and that you have the proper permissions to save filesto the server. In addition to this, the server will need enough space to hold the backupfile.Incorrect Answers:E. In order to simply back up the IOS file, the server needs to only be able to save it to ahard disk. It does not need to load, read, or boot the image.QUESTION 448:Router CK1 is not operating as expected and you want to verify that the routerbooted using the correct IOS image. Which command should be used to determinewhich IOS is running on the router?A.
show memoryB. show flashC. show versionD. show startup-configE. show config-registerF. None of the aboveAnswer: CExplanation:The "show version" command displays info about the router and IOS running in RAM asshown below:Actualtests.com - The Power of Knowing640-802QUESTION 449:A portion of the Certkiller network is shown in the following exhibit:Actualtests.com - The Power of Knowing640-802You work as a network technician at Certkiller .com. Study the exhibit carefully. TheCertkiller network administrator requires easy configuration options and minimalrouting protocol traffic.
What two options provide adequate routing tableinformation for traffic that passes between the two routers and satisfy the requestsof the network administrator? (Choose two)A. A dynamic routing protocol on Certkiller 1 to advertise summarized routes toCertkiller 2B. A dynamic routing protocol Certkiller 2 to advertise summarized routes a Certkiller 1C. A static route on Certkiller 2 to direct traffic that is destined for 172.16.0.0/16 toCertkiller 1D. A dynamic routing protocol on Certkiller 2 to advertise all routes a Certkiller 1E.
A dynamic routing protocol on Certkiller 1 to advertise all routes to Certkiller 2F. A static, default route on Certkiller 1 that directs traffic to Certkiller 2Answer: C, FQUESTION 450:Four different Certkiller routers are connected together as shown below:Actualtests.com - The Power of Knowing640-802Based on the information shown above, how will router Certkiller 1 choose a path tothe 10.1.2.0/24 network when different routing protocols are configured? (Choosethree)A.
If RIPv2 is the routing protocol, the equal coast pathsCertkiller 1- Certkiller 2- Certkiller 4 and Certkiller 1- Certkiller 3- Certkiller 4 will be installedin the routing table by defaultB. If EIGRP is the routing protocol, only the path Certkiller 1- Certkiller 4 will be installedin the routing table by defaultC. If RIPv2 is the routing protocol, only the path Certkiller 1- Certkiller 4 will be installedin the routing table by defaultD. If EIGRP and OSPF are both running on the network, the EIGRP paths will beinstalled in the routing tableE.
If EIGRP and OSPF are both running on the network, the OSPF paths will be installedin the routing tableF. If EIGRP is the routing protocol, the equal cost paths Certkiller 1- Certkiller 2- Certkiller 4and Certkiller 1- Certkiller 3- Certkiller 4will be installed in the routing table by defaultAnswer: C, D, FExplanation:Path selection criteria for RIP and RIPv2 is hop count so path CK1 - CK4 will be usedbecause of 1 hop count. Choice C is correct.EIGRP has lower administrative distance of 90 than OSPF 110 so EIGRP will bepreferred. Choice D is correct.EIGRP uses bandwidth for the path selection criteria and load balances by default forequal cost paths, making choice F correct.QUESTION 451:When designing OSPF networks; what is the purpose of using a hierarchicalActualtests.com - The Power of Knowing640-802design? (Select all choices that apply)A.
To reduce the complexity of router configurationB. To speed up convergenceC. To confine network instability to single areas of the networkD. To reduce routing overheadE. To lower costs by replacing routersF. To decrease latencyAnswer: B, C, DExplanation:An OSPF network designed in a hierarchical fashion with different areas is used becausea small change in the topology of a single area won't force every router to run the SPFalgorithm. Changes in one area are limited to that area only, not to every router withinthe entire network. Confining the topology changes to one area reduces the overhead andspeeds the convergence of the network.Reference: CCNA Self-Study CCNA ICND exam certification Guide (Cisco Press,ISBN 1-58720-083-X) Page 194Incorrect Answers:A.
This choice is incorrect because a hierarchical design actually adds complexity to therouter configuration.E. This is incorrect because a hierarchical design will not eliminate the need for routers.In fact, segmenting the network into multiple areas may actually require the use ofadditional routers.F. The use of a hierarchical design will in no way reduce the latency involved. Ifadditional routers are implemented in order to segment the network into additional areas,then the latency involved may actually increase.QUESTION 452:You are a network administrator and you need to implement a routing protocol onyour network that provides:* Scalability* VLSM support* Minimal overhead* Support for connecting networks using routers of multiple vendorsWhich of the following routing protocol would best serve your needs?A.
VTPB. RIP version 1C. EIGRPD. OSPFE. IGRPActualtests.com - The Power of Knowing640-802F. CDPAnswer: DExplanation:Since one of the requirements is that the routing protocol must support other vendors, ouronly choices are RIP and OSPF. Since RIP version 1 does not support VLSM, OSPF isthe only choice.Incorrect Answers:A. VTP is the VLAN Trunking Protocol. This is not a routing protocol.B. RIP version one does not support VLSM.
