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
servercomputer : 3
clientcomputer : 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
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 bothtwo computer ,
thecard configuraton:
MAC address : 10c80500000000
IRQ : 5
I/O : 300
transceiver: RJ-45
DMA : NONe
memory address : none
which change must you maketo 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 configurewrongI/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.
Whichcause 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 ?
A: DHCP srver
B: WINS server
C: Gateway
D: router
ans:b
11.
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 ,you 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
c: upgrade the WAN connextion to 1.5Mbps
D: Add RAM to database server
ans:c
12.
You have just connected your network from NETBEUI to TCP/IP , The server and client are located on differentsubnets.From 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
D: your client computer s name is not registed with the name server
ans:c
13.
Sometimes , the client are not able to access the server , what must you do to restore reliable communicatuon ?

ans:b
14:
Your routed network has token-ring and 10BaseT Ethernet subnet. the token-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 ?
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
