Subject: passed my networking essentials
hey, thanks for the great web page u got. it really really helped me out a lot. i took the test today, july 17, 1998. and i passed! on my first try. thank God. i really learned a great deal more from the braindumps then the book. kinda sad to say. the braindumps is the the exam itself. thanks. heres what i remember...( i was too happy to remember everything..) i didnt have any questions on the OSI model, none. was kinda shocked. most of the questions were from things u should really know like routers, brouters, bridges, and gateways. know the functions and what situations they could be used in.
also know troubleshooting equipment like protocol analyzers(about 4 questions with this), TDR (time-domain reflectometers, esp. volt-ohm meter (2 questions with this).
one question went like this :
u have a ethernet network using two cable types RG-58 /u and RG-58 a/u , and ur having problems with the pcs cuz they all keep going down? what do u do?
a. change all cables to RG-58 a/u
2. I had to consecutive questions on NWLink IPX/SPX....
The answer to both was incorrect frame settings.... If you don't have a incorrect frame type try wrong tranciever type.. If the network software initializes properly then the drivers , IRO etc are all correct..
3. I got 8 sceanrios....
a) Three cites connected by 3 T1 lines in a triangle...
b) Three cities conected by 2 T1 lines....
Remember that in the triangle configuration even if one link goes down the computers can still communicate at 1 mbps...but no in the case where u are using 2 T1 lines....
c) NETBIOS naming scenarios.....
Using e-mail addresses
Using hexadecimal....(Hexadecimal is a valid choice for NETBIOS names if under 15 charcters are used )
A Hexadecimal naming system is valid but does not make any sense...
d) Trouble shooting scenarios....
To improve network perfomance to 50 % Remember that an Ethernet switch is an Intelligent hub...So it does improve network performance
IRQ 6 : Floppy Disk Controller
IRQ 7 : LPT1 4) Know ur IRQ's
IRQ 3 : COM 2,COM 4
IRQ 4 : COM 1, COM3
IRQ 5 (Default for NIC) : Sound card / LPT2 / NIC
11) Basic rate ISDN is going to replace Analog telephone...
12 ) Fucntions and advantages of NDIS..( Multiple protocols on same adapter..)
13 ) If ur network has only Win95 or WfW computers the u cannot use User- Level Security..
1. 3 cities connected with 2 T1 lines. Required result: connect at 1Mbs.
Optional: connected also if 1 link fail <--only req.
8. You have a network with Windows95, windows nt, Mac, Dos, with protocols:
IPX/SPX, NetBeui, AppleTalk and 4 brouters . You have to much broadcast storm.
How can you resolve the problem with minimum cost? <--- use only IPX/SPX and
AppleTalk, and turn off the bridging on brouters.
2 NDIS/OSI questions: bind multiple protocols on 1 NIC
UNC name: computer and share name
WINS 95, WFW: share level
Wins NT: user level
Client/server definition
App,File, and Print Server question
PPP/SLIP: which one is guaranteed delivery, which one has error control and compression (PPP)
Your company wants to protect the servers from hardware failure, with periods of 2hrs downtime acceptable.
Implement reasonable controls to protect from data loss.
OPT: Track all access to data
--Protect from viruses.
SOLUTION: UPS, Access control on shared resources, RAID 5, Daily Backups, Viruscan on PC's, implement auditing.
20. Know the following protocols, what they're for, and when to use them: TCP/IP, IPX/SPX (or NWLink), NetBEUI, AppleTalk.
9. Nwlink network INITIALIZATION of client is OK, client can't get to server.,other computers can. Why?
Ans: net adapter incorrect frame type.
9. Nwlink network INITIALIZATION of client is OK, client can't get to server.,other computers can. Why?
Ans: net adapter incorrect frame type.
18 You have to set up 2 computers to connect to the network. All components IRQ'S are set ot deault value. You have to set up both NIC with the following:
MAC address = 0114AS558957; IRQ = 5; I/O Base Memory = 300. The computers are not able to communicate o
Ans. RESET MAC address to factroy settings
my advice is to also check other peoples answers and see what they got to say because they were mostly right. exactly out of the exams. also another good thing to do is to go over the answers of the transcendors. very helpful.
thanks rob for this great website.
take care.
and good luck to all.
