network monitoring shows that network utilization has grow from 30 percent to 70 pencent of maximum capacity in the past year.爕ou add 24 client computers and 1 server within 3 months. you want to reduce network utilization.
the following is configuration of network
server燾omputer : 3
client燾omputer : 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
optional desired results:
.keep with continuous increase network application
.maintain new network application level after the plan implmentation
.minimum costs
proposed solution :
replace 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 requirment
ans:

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

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爐wo computer ,
the燾ard configuraton:
mac address : 10c80500000000
irq : 5
i/o : 300
transceiver: rj-45
dma : none
memory address : none
which change must you make爐o 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爓rong爄/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,燾omputer boot nomally.
which燾ause this?
a:爑mb 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.燼ll 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 ,燼ll 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

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 ?
a: dhcp srver
b: wins server
c: gateway
d: router
ans:b

you are administrator of 300 computers ethernet network .
your users access database server across a 56k bps wan connection. the users report that the database server respond slowly ,爕ou have alreadly optimized the database server.
what you do to produce the great improvement in performance?
a: replace the existing network adapter and cableing tith 16 mbps token-ring equivalent
b: upgrade the existing network adapter to 32 bit card

you have just connected your network from netbeui to tcp/ip , the server and client are located on different爏ubnets.爁rom your client , you are able to ping the server by using ip address, but you can t access the server by server s name.
what s the most likely cause?
a: client and server have same ip address
b: server is configure use wrong subnet mask
c: server s name is not registed with the name server

your routed network has token-ring and 10baset ethernet subnet. the token-ring net run at 4mbps, the network use tcp/ip,燾opying 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 ?
a: tcp window size is too larger
b: the token-ring is slower than the ethernet
c: the packet size on the token-ring subnet is larger than the packet size on the ethernet subnet
d: the token-ring subnet is configured to use teh wrong frame type
ans:c
