1、cable type :category 3 utp router :none bridge :desired resolution: you must reduce network utilization by 50 percent optional desired results:.keep with continuous increase network application .maintain new network application level after the plan implmentation .minimum costs proposed solution :rep
2、lace all category 3 utp with fib-optic cable , replace all network adapter card with fddi network adapter which one is proposed results?a: match the requirment and all of optional were match b: match the requirment and only 2 of optional c: match the requirment and nono of optional d: not match requ
3、irment ans:2. 120 distribute among the 3 servers proposed solution:change packet size from 1514 bytes to 576 bytes replace all cataloty 3 utp with category 5 utp increase tcp window size from 4096 bytes to 16384 bytes d 3. you are the administrator of a routed wan(wide area network) , user on segmen
4、t report usually slow network response. after investigation , you decide that hardware is not the reason , you suspect that broadcast storm. what should you do next? shut down the servers on affected segment shut down router on affected segment use a protocol analyzer to identify the source use a ti
5、me domain reflecter(tdr) to identity the source c 4. computer networks use coaxial cable. network communication are not reliable . what must you do to repaire ? replace 50 ohm terminator with 25 ohm replace all tg 58 a/u cable with rg 62 reconfigure the network cable use only 2 terminators reconfigu
6、re the network that network length does not exceed the specification 5.two client computers have same configuration as following vga : default ide :floppy disk :lpt1:default com1:com2:ethenet network adapter set below both of two computers are not able to access network ,you run diagnous test on ada
7、pter in both two computer , the card configuraton:mac address : 10c80500000000 irq : 5 i/o : 300 transceiver: rj-45 dma : none memory address :which change must you make to allow two client computers to access the network change the mac address change irq to 3 change i/o to 320 change transceiver to
8、 bnc a 6:network protocol use nwlink ipx , client computer network software innital success , but client computer not able to access the server. all of other client computer are able . what s the most like cause? wrong network adapter drive installed client computer has not enough memory network ada
9、pter configure wrong i/o address wrong frame type use in client computer network adapter 7. add 486 based client computer to network , client has 16 ram , a scsi cd-rom , a scsi harddisk , after install a network adapter , computer not boot from the harddisk . you remove the network card, computer b
10、oot nomally. which cause this? umb conflict between the scsi adapter and network adapter irq conflict between the scsi adapter and network adapter emm386 conflict bus slot conflict between . b 8. anne report her client computer no longer access network resource. all of other computer on her segment
11、work properly incorrect protocol loose network cable connection incorrect termination frame type mismatch the client and server 9. tom s client can t access server , all of other client can. how to identify the cause? run diagnous on the network adapter in tom s run diagnous on ram in tom s computer
12、 examine the server s protocol configure examine hte server s network cable connection 10. network configuration as following server : 5 total run microsoft windows nt server one also run dhcp, one also run wins client : 200 tcp/ip gateway : sna server communication on your routed network is success
13、ful when users of the client specify a server s ip address , but failure when specify the srver s name what should you examine first ? dhcp srver wins server gateway router 11. you are administrator of 300 computers ethernet network . your users access database server across a 56k bps wan connection
14、. the users report that the database server respond slowly , you have alreadly optimized the database server. what you do to produce the great improvement in performance? replace the existing network adapter and cableing tith 16 mbps token-ring equivalent upgrade the existing network adapter to 32 b
15、it card upgrade the wan connextion to 1.5mbps add ram to database server 12. you have just connected your network from netbeui to tcp/ip , the server and client are located on different subnets. from your client , you are able to ping the server by using ip address, but you can t access the server b
16、y server s name. what s the most likely cause? client and server have same ip address server is configure use wrong subnet mask server s name is not registed with the name server your client computer s name is not registed with the name server 13. sometimes , the client are not able to access the se
17、rver , what must you do to restore reliable communicatuon ? replace the 50 ohm terminator with 25 ohm connecte the network properly terminate the network properly reinstall the nerwork client software on each client computer 14:your routed network has token-ring and 10baset ethernet subnet. the toke
18、n-ring net run at 4mbps, the network use tcp/ip, copying a 5mb file from the token-ring to ethernet takes up to 2 minutes, however copy the file from ethernet to token-ring takes less than 30 seconds . what s the most likely cause ? tcp window size is too larger the token-ring is slower than the ethernet the packet size on the token-ring subnet is larger than the packet size on the ethernet subnet the token-ring subnet is configured to use teh wrong frame type 基础知识篇(1) 相关内容:
