1 CCNA 1 Chapter v5.1 Answers 100% 1. Which characteristic f the netwrk layer in the OSI mdel allws carrying packets fr multiple types f cmmunicatins amng many hsts? the de-encapsulatin f headers frm lwer layers the selectin f paths fr and direct packets tward the destinatin the ability t perate withut regard t the data that is carried in each packet the ability t manage the data transprt between prcesses running n hsts 2. What are tw characteristics f IP? (Chse tw.) des nt require a dedicated end-t-end cnnectin perates independently f the netwrk media retransmits packets if errrs ccur re-assembles ut f rder packets int the crrect rder at the receiver end guarantees delivery f packets 3. When a cnnectinless prtcl is in use at a lwer layer f the OSI mdel, hw is missing data detected and retransmitted if necessary? Cnnectinless acknwledgements are used t request retransmissin. Upper-layer cnnectin-riented prtcls keep track f the data received and can request retransmissin frm the upper-level prtcls n the sending hst. Netwrk layer IP prtcls manage the cmmunicatin sessins if cnnectinriented transprt services are nt available. The best-effrt delivery prcess guarantees that all packets that are sent are received. 4. Which field in the IPv4 header is used t prevent a packet frm traversing a netwrk endlessly? Time-t-Live Sequence Number Acknwledgment Number Differentiated Services 5. What IPv4 header field identifies the upper layer prtcl carried in the packet? Prtcl Identificatin Versin Differentiated Services 6. What is ne advantage that the IPv6 simplified header ffers ver IPv4? smaller-sized header little requirement fr prcessing checksums smaller-sized surce and destinatin IP addresses CCNA 5 Page 1

2 efficient packet handling 7. Refer t the exhibit. Which rute frm the PC1 ruting table will be used t reach PC2?. CCNA1 Chapter 6 v CCNA1 Chapter 6 Exam 001 pt 1. CCNA1 Chapter 6 Exam 001 pt 2 CCNA 5 Page 2

3 . CCNA1 Chapter 6 Exam 001 pt 3 CCNA1 Chapter 6 Exam 001 pt 4 8. Refer t the exhibit. R1 receives a packet destined fr the IP address Out which interface will R1 frward the packet? CCNA1 Chapter 6 v FastEthernet0/0 FastEthernet0/1 Serial0/0/0 Serial0/0/1 9. What type f rute is indicated by the cde C in an IPv4 ruting table n a Cisc ruter? static rute default rute directly cnnected rute dynamic rute that is learned thrugh EIGRP CCNA 5 Page 3

4 10. What ruting table entry has a next hp address assciated with a destinatin netwrk? directly-cnnected rutes lcal rutes remte rutes C and L surce rutes 11. Which statement describes a hardware feature f a Cisc 1941 ruter that has the default hardware cnfiguratin? It des nt have an AUX prt. It has three FastEthernet interfaces fr LAN access. It has tw types f prts that can be used t access the cnsle. It des nt require a CPU because it relies n Cmpact Flash t run the IOS. 12. Fllwing default settings, what is the next step in the ruter bt sequence after the IOS lads frm flash? Perfrm the POST rutine. Lcate and lad the startup-cnfig file frm NVRAM. Lad the btstrap prgram frm ROM. Lad the running-cnfig file frm RAM. 13. What are tw types f ruter interfaces? (Chse tw.) SVI LAN DHCP Telnet WAN 14. Which tw pieces f infrmatin are in the RAM f a Cisc ruter during nrmal peratin? (Chse tw.) Cisc IOS backup IOS file IP ruting table basic diagnstic sftware startup cnfiguratin file 15. A ruter bts and enters setup mde. What is the reasn fr this? The IOS image is crrupt. Cisc IOS is missing frm flash memry. The cnfiguratin file is missing frm NVRAM. The POST prcess has detected hardware failure. 16. What is the purpse f the startup cnfiguratin file n a Cisc ruter? t facilitate the basic peratin f the hardware cmpnents f a device CCNA 5 Page 4

5 t cntain the cmmands that are used t initially cnfigure a ruter n startup t cntain the cnfiguratin cmmands that the ruter IOS is currently using t prvide a limited backup versin f the IOS, in case the ruter cannt lad the full featured IOS 17. Which three cmmands are used t set up secure access t a ruter thrugh a cnnectin t the cnsle interface? (Chse three.) interface fastethernet 0/0 line vty 0 4 line cnsle 0 enable secret cisc lgin passwrd cisc 18. Which characteristic describes an IPv6 enhancement ver IPv4? IPv6 addresses are based n 128-bit flat addressing as ppsed t IPv4 which is based n 32-bit hierarchical addressing. The IPv6 header is simpler than the IPv4 header is, which imprves packet handling. Bth IPv4 and IPv6 supprt authenticatin, but nly IPv6 supprts privacy capabilities. The IPv6 address space is fur times bigger than the IPv4 address space. 19. Open the PT Activity. The enable passwrd n all devices is cisc. Perfrm the tasks in the activity instructins and then answer the questin. Fr what reasn is the failure ccurring? PC1 has an incrrect default gateway cnfigured. SW1 des nt have a default gateway cnfigured. The IP address f SW1 is cnfigured in a wrng subnet. PC2 has an incrrect default gateway cnfigured. 20. Match the cmmand with the device mde at which the cmmand is entered. (Nt all ptins are used.) Questin CCNA 5 Page 5
