1 CCNA 1 Chapter v5.1 Answers 100% 1. What is a result f cnnecting tw r mre switches tgether? The number f bradcast dmains is increased. The size f the bradcast dmain is increased. The number f cllisin dmains is reduced. The size f the cllisin dmain is increased. 2. Refer t the exhibit. Hw many bradcast dmains are there? CCNA1 Chapter 8 v What are tw reasns a netwrk administratr might want t create subnets? (Chse tw.) simplifies netwrk design imprves netwrk perfrmance easier t implement security plicies reductin in number f ruters needed reductin in number f switches needed 4. Refer t the exhibit. A cmpany uses the address blck f /16 fr its netwrk. What subnet mask wuld prvide the maximum number f equal size subnets while prviding enugh hst addresses fr each subnet in the exhibit? CCNA 5 Page 1

2 CCNA1 Chapter 8 v Refer t the exhibit. The netwrk administratr has assigned the LAN f LBMISS an address range f This address range has been subnetted using a /29 prefix. In rder t accmmdate a new building, the technician has decided t use the fifth subnet fr cnfiguring the new netwrk (subnet zer is the first subnet). By cmpany plicies, the ruter interface is always assigned the first usable hst address and the wrkgrup server is given the last usable hst address. Which cnfiguratin shuld be entered int the prperties f the wrkgrup server t allw cnnectivity t the Internet? CCNA 5 Page 2

3 CCNA1 Chapter 8 v IP address: subnet mask: , default gateway: IP address: subnet mask: , default gateway: IP address: subnet mask: , default gateway: IP address: subnet mask: , default gateway: IP address: subnet mask: , default gateway: If a netwrk device has a mask f /28, hw many IP addresses are available fr hsts n this netwrk? Which subnet mask wuld be used if 5 hst bits are available? CCNA 5 Page 3

4 Hw many hst addresses are available n the netwrk with a subnet mask f ? Hw many bits must be brrwed frm the hst prtin f an address t accmmdate a ruter with five cnnected netwrks? tw three fur five 10. A netwrk administratr wants t have the same netwrk mask fr all netwrks at a particular small site. The site has the fllwing netwrks and number f devices: IP phnes 22 addresses PCs 20 addresses needed Printers 2 addresses needed Scanners 2 addresses needed The netwrk administratr has deemed that /24 is t be the netwrk used at this site. Which single subnet mask wuld make the mst efficient use f the available addresses t use fr the fur subnetwrks? A cmpany has a netwrk address f with a subnet mask f The cmpany wants t create tw subnetwrks that wuld cntain 10 hsts and 18 hsts respectively. Which tw netwrks wuld achieve that? (Chse tw.) / / / / /28 CCNA 5 Page 4

5 12. A netwrk administratr is variably subnetting a netwrk. The smallest subnet has a mask f Hw many usable hst addresses will this subnet prvide? Refer t the exhibit. Given the netwrk address f and a subnet mask f , hw many ttal hst addresses are unused in the assigned subnets? CCNA1 Chapter 8 v Refer t the exhibit. Cnsidering the addresses already used and having t remain within the /24 netwrk range, which subnet address culd be assigned t the netwrk cntaining 25 hsts? CCNA 5 Page 5

6 CCNA1 Chapter 8 v / / / / / / A netwrk administratr needs t mnitr netwrk traffic t and frm servers in a data center. Which features f an IP addressing scheme shuld be applied t these devices? 1. randm static addresses t imprve security 2. addresses frm different subnets fr redundancy 3. predictable static IP addresses fr easier identificatin 4. dynamic addresses t reduce the prbability f duplicate addresses 16. Which tw reasns generally make DHCP the preferred methd f assigning IP addresses t hsts n large netwrks? (Chse tw.) It eliminates mst address cnfiguratin errrs. It ensures that addresses are nly applied t devices that require a permanent address. It guarantees that every device that needs an address will get ne. It prvides an address nly t devices that are authrized t be cnnected t the netwrk. It reduces the burden n netwrk supprt staff. 17. A DHCP server is used t assign IP addresses dynamically t the hsts n a netwrk. The address pl is cnfigured with /24. There are 3 printers n this netwrk that need t use reserved static IP addresses frm the pl. Hw many IP addresses in the pl are left t be assigned t ther hsts? CCNA 5 Page 6

7 Refer t the exhibit. A cmpany is deplying an IPv6 addressing scheme fr its netwrk. The cmpany design dcument indicates that the subnet prtin f the IPv6 addresses is used fr the new hierarchical netwrk design, with the site subsectin t represent multiple gegraphical sites f the cmpany, the sub-site sectin t represent multiple campuses at each site, and the subnet sectin t indicate each netwrk segment separated by ruters. With such a scheme, what is the maximum number f subnets achieved per sub-site? CCNA1 Chapter 8 v What is the prefix fr the hst address 2001:DB8:BC15:A:12AB::1/64? 2001:DB8:BC :DB8:BC15:A 2001:DB8:BC15:A:1 2001:DB8:BC15:A: Cnsider the fllwing range f addresses: 2001:0DB8:BC15:00A0:0000:: 2001:0DB8:BC15:00A1:0000:: 2001:0DB8:BC15:00A2:0000:: CCNA 5 Page 7

8 2001:0DB8:BC15:00AF:0000:: The prefix-length fr the range f addresses is / Match the subnetwrk t a hst address that wuld be included within the subnetwrk. (Nt all ptins are used.) Questin CCNA1 Chapter 8 v Questin Answer CCNA1 Chapter 8 v Answer 22. Refer t the exhibit. Match the netwrk with the crrect IP address and prefix that will satisfy the usable hst addressing requirements fr each netwrk. (Nt all ptins are used.) CCNA 5 Page 8
