1 CCNA 1 Chapter v5.1 Answers 100% 1. A newly hired netwrk technician is given the task f rdering new hardware fr a small business with a large grwth frecast. Which primary factr shuld the technician be cncerned with when chsing the new devices? devices with a fixed number and type f interfaces devices that have supprt fr netwrk mnitring redundant devices devices with supprt fr mdularity 2. Which netwrk design cnsideratin wuld be mre imprtant t a large crpratin than t a small business? Internet ruter firewall lw prt density switch redundancy 3. Which tw traffic types require delay sensitive delivery? (Chse tw.) web FTP vice vide 4. A netwrk administratr fr a small cmpany is cntemplating hw t scale the netwrk ver the next three years t accmmdate prjected grwth. Which three types f infrmatin shuld be used t plan fr netwrk grwth? (Chse three.) human resurce plicies and prcedures fr all emplyees in the cmpany dcumentatin f the current physical and lgical tplgies analysis f the netwrk traffic based n prtcls, applicatins, and services used n the netwrk histry and missin statement f the cmpany inventry f the devices that are currently used n the netwrk listing f the current emplyees and their rle in the cmpany 5. Which tw statements describe hw t assess traffic flw patterns and netwrk traffic types using a prtcl analyzer? (Chse tw.) Capture traffic n the weekends when mst emplyees are ff wrk. Only capture traffic in the areas f the netwrk that receive mst f the traffic such as the data center. Capture traffic during peak utilizatin times t get a gd representatin f the different traffic types. Perfrm the capture n different netwrk segments. CCNA 5 Page 1

2 Only capture WAN traffic because traffic t the web is respnsible fr the largest amunt f traffic n a netwrk. 6. Sme ruters and switches in a wiring clset malfunctined after an air cnditining unit failed. What type f threat des this situatin describe? cnfiguratin envirnmental electrical maintenance 7. Which type f netwrk threat is intended t prevent authrized users frm accessing resurces? DS attacks access attacks recnnaissance attacks trust explitatin 8. Which tw actins can be taken t prevent a successful netwrk attack n an server accunt? (Chse tw.) Never send the passwrd thrugh the netwrk in a clear text. Never use passwrds that need the Shift key. Use servers frm different vendrs. Distribute servers thrughut the building, placing them clse t the stakehlders. Limit the number f unsuccessful attempts t lg in t the server. 9. Which firewall feature is used t ensure that packets cming int a netwrk are legitimate respnses initiated frm internal hsts? applicatin filtering stateful packet inspectin URL filtering packet filtering 10. What is the purpse f the netwrk security authenticatin functin? t require users t prve wh they are t determine which resurces a user can access t keep track f the actins f a user t prvide challenge and respnse questins 11. A netwrk administratr is issuing the lgin blck-fr 180 attempts 2 within 30 cmmand n a ruter. Which threat is the netwrk administratr trying t prevent? a user wh is trying t guess a passwrd t access the ruter a wrm that is attempting t access anther part f the netwrk CCNA 5 Page 2

3 an unidentified individual wh is trying t access the netwrk equipment rm a device that is trying t inspect the traffic n a link 12. What is the purpse f using SSH t cnnect t a ruter? It allws a ruter t be cnfigured using a graphical interface. It allws a secure remte cnnectin t the ruter cmmand line interface. It allws the ruter t be mnitred thrugh a netwrk management applicatin. It allws secure transfer f the IOS sftware image frm an unsecure wrkstatin r server. 13. Which tw steps are required befre SSH can be enabled n a Cisc ruter? (Chse tw.) Give the ruter a hst name and dmain name. Create a banner that will be displayed t users when they cnnect. Generate a set f secret keys t be used fr encryptin and decryptin. Set up an authenticatin server t handle incming cnnectin requests. Enable SSH n the physical interfaces where the incming cnnectin requests will be received. 14. What is the purpse f issuing the cmmands cd nvram: then dir at the privilege exec mde f a ruter? t clear the cntent f the NVRAM t direct all new files t the NVRAM t list the cntent f the NVRAM t cpy the directries frm the NVRAM 15. Which cmmand will backup the cnfiguratin that is stred in NVRAM t a TFTP server? cpy running-cnfig tftp cpy tftp running-cnfig cpy startup-cnfig tftp cpy tftp startup-cnfig 16. Refer t the exhibit. Baseline dcumentatin fr a small cmpany had ping rund trip time statistics f 36/97/132 between hsts H1 and H3. Tday the netwrk administratr checked cnnectivity by pinging between hsts H1 and H3 that resulted in a rund trip time f 1458/2390/6066. What des this indicate t the netwrk administratr? CCNA 5 Page 3

4 CCNA1 Chapter 11 v Cnnectivity between H1 and H3 is fine. H3 is nt cnnected prperly t the netwrk. Smething is causing interference between H1 and R1. Perfrmance between the netwrks is within expected parameters. Smething is causing a time delay between the netwrks. 17. When shuld an administratr establish a netwrk baseline? when the traffic is at peak in the netwrk when there is a sudden drp in traffic at the lwest pint f traffic in the netwrk at regular intervals ver a perid f time 18. Refer t the exhibit. An administratr is trying t trublesht cnnectivity between PC1 and PC2 and uses the tracert cmmand frm PC1 t d it. Based n the displayed utput, where shuld the administratr begin trubleshting? CCNA 5 Page 4

5 CCNA1 Chapter 11 v PC2 R1 SW2 R2 SW1 19. Which statement is true abut CDP n a Cisc device? The shw cdp neighbr detail cmmand will reveal the IP address f a neighbr nly if there is Layer 3 cnnectivity. T disable CDP glbally, the n cdp enable cmmand in interface cnfiguratin mde must be used. CDP can be disabled glbally r n a specific interface. Because it runs at the data link layer, the CDP prtcl can nly be implemented in switches. 20. A netwrk administratr fr a small campus netwrk has issued the shw ip interface brief cmmand n a switch. What is the administratr verifying with this cmmand? the status f the switch interfaces and the address cnfigured n interface vlan 1 that a specific hst n anther netwrk can be reached the path that is used t reach a specific hst n anther netwrk the default gateway that is used by the switch CCNA 5 Page 5

6 21. A netwrk technician issues the arp -d * cmmand n a PC after the ruter that is cnnected t the LAN is recnfigured. What is the result after this cmmand is issued? The ARP cache is cleared. The current cntent f the ARP cache is displayed. The detailed infrmatin f the ARP cache is displayed. The ARP cache is synchrnized with the ruter interface. 22. Fill in the blank. VIP defines the prtcls and technlgies that implement the transmissin f vice data ver an IP netwrk 23. Fill in the blank. D nt use abbreviatins. The shw file systems cmmand prvides infrmatin abut the amunt f free nvram and flash memry with the permissins fr reading r writing data. 24. Fill in the blank. D nt use abbreviatins. The shw versin cmmand that is issued n a ruter is used t verify the value f the sftware cnfiguratin register. 25. Match the type f infrmatin security threat t the scenari. (Nt all ptins are used.)
