　　network monitoring shows that network utilization has grow from 30 percent to 70 pencent of maximum capacity in the past year.　you add 24 client computers and 1 server within 3 months. you want to reduce network utilization.

　　the following is configuration of network

　　server　computer : 3

　　client　computer : 120 distributed among the 3 servers

　　network type : 10baset ethernet

　　protocol :tcp/ip

　　cable type :category 3 utp

　　router :none

　　bridge :none

　　desired resolution:

　　you must reduce network utilization by 50 percent

　　you are the administrator of a routed wan(wide area network) , user on segment 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?

　　a: shut down the servers on affected segment

　　b: shut down router on affected segment

　　c: use a protocol analyzer to identify the source

　　d: use a time domain reflecter(tdr) to identity the source

　　ans:c

　　4.

　　computer networks use coaxial cable. network communication are not reliable .

　　what must you do to repaire ?

　　a: replace 50 ohm terminator with 25 ohm

　　b: replace all tg 58 a/u cable with rg 62

　　c: reconfigure the network cable use only 2 terminators

　　d: reconfigure the network that network length does not exceed the specification

　　ans:d

　　5.

　　two client computers have same configuration as following

　　vga : default

　　ide : default

　　floppy disk : default

　　lpt1:default

　　com1:default

　　com2:default

　　ethenet network adapter set below

　　both of two computers are not able to access network ,you run diagnous test on adapter in both　two computer ,

　　the　card configuraton:

　　mac address : 10c80500000000

　　irq : 5

　　i/o : 300

　　transceiver: rj-45

　　dma : none

　　memory address : none

　　which change must you make　to allow two client computers to access the network

　　a: change the mac address

　　b: change irq to 3

　　c: change i/o to 320

　　d: change transceiver to bnc

　　ans: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?

　　a: wrong network adapter drive installed

　　b: client computer has not enough memory

　　c: network adapter configure　wrong　i/o address

　　d: wrong frame type use in client computer network adapter

　　ans:d

　　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 boot nomally.

　　which　cause this?

　　a:　umb conflict between the scsi adapter and network adapter

　　b: irq conflict between the scsi adapter and network adapter

　　c: emm386 conflict

　　d: bus slot conflict between .......

　　ans:b

　　8.

　　anne report her client computer no longer access network resource.　all of other computer on her segment work properly

　　which cause this?

　　a: incorrect protocol

　　b: loose network cable connection

　　c: incorrect termination

　　d: frame type mismatch the client and server

　　ans:b

　　9.

　　tom s client can t access server ,　all of other client can.

　　how to identify the cause?

　　a: run diagnous on the network adapter in tom s

　　b: run diagnous on ram in tom s computer

　　c: examine the server s protocol configure

　　d: examine hte server s network cable connection

　　ans:a

　　10.

　　network configuration as following

　　server : 5 total run microsoft windows nt server

　　one also run dhcp, one also run wins

　　client : 200

　　protocol : tcp/ip

　　gateway : sna server

　　communication on your routed network is successful when users of the client specify a server s ip

　　address , but failure when specify the srver s name

　　what should you examine first ?
