Hello all. My name is Humpty. I took the Networking Essentials test recently and passed with a score of 965 out of 1000 (first time). I only missed two. Granted, I am attending a college that teaches most of this stuff, but this site helped me focus my studies. Below is what I composed out of all that I found off of braindump study sites. Some answers are right, some are wrong, and some dont have answers. This will make YOU get off your butt and look it up :)~. Here it goes...
What is the name of the "number sequence" you need for handling an IP-Adress ?
Answer: Subnetmask.
You can ping a serverby it's IPaddress (numerical), but can't reach it by it's name. What's wrong?
Answer: Wins-Server.
You have connected a Token Ring Network (4MBit/s) and an Ethernet Network. Copying from Token Ring to Ethernet for a 5MB File takes 30 seconds. Copying from Ethernet to Token Ring takes 2Minutes. Why ? Answer: ?
With which devices can you measure the bandwith of a new installation side ?
Network Analyzer
2. Segmented Lans, How do you create them? Routers, Bridges
3. Which protocols are routable/not routable?
Routable: XNS,OSI,IP,IPX,APPLTALK,DecNet
Non-routable: DLC ,LAT ,NETBEUI
4. What do you use for Peer to Peer? no Netbeui, then IPX/XPS
10. Which supports compression and error control? PPP
17. Which is a feature of WinNT 4.0 WS? User level passwords
23. What does a File/Print Server do?
The differences between share-level and user-level security. Share-level is usually peer-to-peer, User-level is server based.
Know the purpose of NDIS and ODI specifications. Namely, that different protocols can be bound to one network card driver.
Had one question on UNC (universal naming convention). Just remember: \\Computername\sharename
Which WAN technology is intended to replace analog phone lines? ISDN.
Know the different fault tolerance RAID levels. Two questions asked dealt with levels 1 and 5 on my test.
Routers do not transmit broadcast messages.
Installing and troubleshooting network adapter cards. If you are sure the IRQ setting is correct, then check the frame type if using IPX protocol. IPX can not determine frame type automatically.
If ONLY one client machine cannot access the network, then the problem is in the client machine, e.g. wrong transceiver setting, frame type, or IRQ.
To resolve broadcast storms, use routers. One question asked about brouters (hint - turn off the bridging feature on brouters to resolve storms).
2. Why does a high number of broadcast messages adversely affect overall network performance?
Each broadcast message requires an acknowledgement packet from every computer on the network
Every computer on the network must process each broadcast message.
3. Which layers of the OSI model are managed by a network protocol such as Microsoft NetBEUI?
Transport and session
6. Which limitation are NDIS and Novell ODI designed to overcome?
The need to dynamically bind a single protocol to multiple MAC drivers in order to support more than one network operating system
The need for proprietary network interface drivers for each network operating system and protocol
Monolithic protocols do not conform to the OSI model
Monolithic protocols cannot be loaded into the upper memory area
7. What does the MAC driver do?
It defines how data should be presented to the next receiving layer, packages the data accordingly, and then passes data to the application through the session layer interface.
It provides low-level access to network adapters by providing data transmission support and some basic adapter management functions
It supports communication between applications on different computers by creating sessions, defining data-exchange formats, and providing application-support services
It is responsible for establishing logical names on the network, establishing connections between two logical names on the network, and supporting reliable data transfer between computers that have established a session
10. What does the transport protocol do?
It defines how data should be presented to the next receiving layer, packages the data accordingly, ad then passes data to the application though the session layer interface.
It provides low-level access to network adapters by providing data transmission support and some basic adapter management functions
It supports communications between applications on different computers by creating sessions, defining data-exchange formats, and providing application-support services
It is responsible for establishing logical names on the network, establishing connections between two logical names on the network, and supporting reliable data transfer between computers that have established a session
Three cities connected using RAS for WAN connections, 8 each 28.8 modems on 16 port hubs to all three cities. No mention of multilink, or multiplexing. Required: 1Mps wan connection
I said: (d) does not meet.
Three cities connected using T-1 and asynchonous 9600bps lines. LA (t1
& async)to Chi (t1 & async) to NY
Required: wan connections to meet minimum of 1mps.
Optional: support connections if one line goes down and maintain 1mps.
I originally had c - meets req. + 1 optional but I changed the answer to d - does not meet because all wan connections are not 1 mps or better. I think now I shld have stayed with c.
1) Reducing the ethernet frame size and increasing the TCP/IP window size does not reduce network utilization by 50%. If anything, it will increase network traffic, because there are now more frames, and each frame has overhead, such as headers and CRC.
14) Know that if there is a problem with network using IPX its probably the frame type.
Two NDIS/ODI questions, beware of the wording, the principle is always the same. NDIS/ODI is a interface for multiple protocols to use the same network adapter.
One question talks about "what problem does NDIS/ODI overcomes", the other "what is the advantage of NDIS/ODI". In the last case the wording was something like "Let compliant transport protocols use compliant network adapters". It's not just an NDIS/ODI characteristic, but the only one by exclusion of the rest of the possible answers.
- Two performance questions of the type "network traffic increase
from 30% to 70%" in a 10BaseT network
Required: Reducing network traffic 50%.
Optional: Reducing cost, not affecting administration, not affection funtions
Proposed: Change all Ethernet componet with Ethernet switches.
I said that this fulfills required and both optional
- A small 10 computer network. Which protocol to use.
There was not NetBEUI among the answers, so I took IPX/SPX
Twoquestions to the following scenario:
You have a network with the data on the servers, in a separate room, NTFS and a lot of more good things. 2 hours downtime acceptable (I asked me "downtime" of what).
Required: You have to assure data protection, fault-tolerance,
Optional: Protection against virus, data access tracking
First solution - Doing backups, granting user-acces, virus-scans and RAID 5 and a lot of beautiful things but not auditing -> Fulfills required and all but tracking options
Second solution - Doing backups, granting user-access, virus-scans and RAID 1 and a lot of beautiful thing more AND auditing -> Fulfills everything.
I HAVE NEVER SEEN - TRANSCEIVER - AND - INCORRECT FRAME TYPE - AS ANSWERS IN THE SAME QUESTION EXCEPT FOR THIS ONE! IF YOU SEE TRANSCEIVER OR INCORRECT FRAME TYPE AS AN ANSWER CHOOSE IT!!!!!!!!
Q. You install Ethernet card on client. computer's network software INITIALIZED properly but computer can not communicate with others on network. any and all other computers can talk to server... Why?
c. Tranceiver on net adapter wrong
Q. Nwlink network. INITIALIZATION of client is ok. client cant get to server. other computers can. why?
c. net adapter incorrect frame type.
Q. What can you use for compression and data packet and tcpip blah blah...
a. PPP
Q. Connect NetBeui on network segment to UNIX on NFS. What do you use?
d. gateway
Q. Connect W95 and MSDOS computers to see data. What protocol to use?
c. NetBeui.
Q. How do you view NETBIOS names on a subnet?
a. wins server
Q. Want to connect Ethernet rings. Use Nwlink and Netbeui. Want to filter data and cut down network traffic. What do you use?
b. bridge
Q. Company has ethernet with 750 computer and have WFW and W95 and NT. Want to protect sensitive network data with minimal downtime. How?

Concept is W95 uses shared
1. Three large cities interconnected by 28.8 modems, in a triagle. Eight modems on each segment. Will you be able to keep a 1Mbps connection if one goes down?
2 situations about rebuilding existing LAN in order to improve security.
High level of security and fast recoverability (within 2 hours) was requested.
Proposed solution describes the stages of constructing secure server-based
LAN with auditing for clients and resourses, server physical security and
backup schedule.
Three cities connected using RAS for WAN connections, 16 each 28.8 modems on 16 port hubs to all three cities (8 going in one direction and 8 in the other). No mention of multilink, nor multiplexing. Required: 1Mbps wan connection.. I said (d) does not meet after debating it, although my original answer was met the required result and all optional. I don't know if I got it right.
When you connect 8 RAS modems here's what you have to take into consideration:
You must put it in an intelligent multiport serial adapter because you only have two com ports and two irqs in your computer. Use of this multiport serial adapter allows you to expand your computer's ability to accommodate 8 modems. The same applies to 16 modems.
When you see this question, you answer "A" which it meets all the required and both optional results.
Three cities connected using T-1 and asynchonous 9600bps lines. LA (t1 & async)to Chi (t1 & async) to NY. Required wan connections to meet minimum of 1mbps. Optional support connections if one line goes down and maintain 1mbps. I answered meets req. + 1 optional.
There were some questions on WINS. Remember that WINS resolves NetBIOS names to IP addresses. DHCP automatically assigns IP addresses to clients.
Remember that routers don't allow broadcasts to pass through and there's questions that talk about routers and broadcasts.
Question on having Windows 95 based computers in a LAN using the NetBEUI protocol and access a Unix computer that's using NFS. I put gateway as the answer.
ATM - except for one that can increase it's bandwidth capability (which you put frame relay as the answer), answer is ATM.
I remembered that the NDIS and ODI question. The NDIS is a standard developed by Microsoft which includes NWLink - Microsoft's implemented driver for Novell Networks. The ODI standard is developed by Apple and Novell. The purpose of both NDIS and ODI is to support multiple protocols on a single network adapter card.
1. What would you include to manage your network? Answer. SNMP.

[x] Windows for Workgroups
[x] Windows 95
[ ] Windows NT workstation
[ ] Windows NT server
User wants to access IBM 3090 via Terminal Emulation, what device?
A: Gateway
Mixed DOS, UNIX, NT network. New NT server, UNIX boxes only can't see it. A: Protocol mismatch between UNIX and new server.
Several Questions on new computers not working but the network software seems to have initialised (which rules out interrupt and base-address conflicts).
Answers were wrong transceiver
type set on NIC and (for NWLink which is IPX) wrong frame type.
Network performance accessing server decreasing. NT Server Utilisation stats are CPU 8%, Page Faults 2 per second and Disk Utilisation 25%.
A: Install RAID Disk Striping of some sort (to speed up disk access).
What do NDIS and ODI give you? A: NICs independent from Protocol.
Two PCs can't communicate over LAN. Using Network diagnosis tools, both have identical hardware and NIC settings (including MAC address, which should of course be unique!).
A: Reset MAC address to factory settings.
What do you need in a UNC Name?
Answer: Server Name, Computer Name,
Domain Name, Share Name? A: Computer and Share.
1. Scenario: Disaster recovery when hardware failure and 2 hour of downtime is allowed. desired: monitor access, clean visus ... solution:
Q1: use UPS, implement policy on shared, install virus software, and implement disk striping on all servers. (no auditing) so my answer was "met the required and only 2 other desired options". WRONG. Diskstriping here means RAID Level 0, which is not redundancy. Diskstriping with parity is the one needed but not in the solution.
Q2: same scenario, same solution except auditing is used. I quickly jumped to Yes met all required and disired options. Wrong again, the answer is the same as above.
Ethernet connected to token ring and only running IPX/SPX, you want to use IPX/SPX addressing to filter data. What should you use: gateway
Q: Scenario: Network of bla bla...... and you want to reduce usage by 50% desired: minimised cost and room for expansion. Solution replace 10baseT cards, cable, hubs with that of 100BaseT.
A: met the required and only one of the desired.
Q: same scinario, same required and desired results. Solutions: reduce the frame size and increase TCP windows size.
A: not meet the required as more frames will cause more collisions and only slowdown the network.
Q: Network perfomance reports a large number of broadcast storm, net is using Netbeui. what is the best thing to do:
Use router and tcp/ip instead of netbeui
Q:Network of 10 windows NT workstations, what can you do with security, chose all applicable:
Anser: both
Q: Windows 95, 10. What security you and set up. Choices are the same as above the answer is sharelevel.
Q.What's the purpose of NDIS:

Answer: wrong frame type.
1. You have five windows 95 peer to peer network. What is the protocol used?
A. NFS
B. XNS
C. DLC <
D. PPP
4. Using NetBEUI and NWLink IPX, want to connect the two segments, and still use both protocols
[ ] repeater
[x] bridge
[ ] router
[ ] gateway
In the NDIS/ODI question all answers are worded weird but choose the one that has the word protocol in it. There are two of these questions but just know it has to do with multiple protocols although they never use the word multiple.
On the two long questions about NetBIOS naming with 20,000 client and servers, required was unique names which must still work after WAN is established, optional must be able to tell server function and user and departments (or something like that) first solution was to use hexadecimal (0 thru 9 a,b,c,d,e,f) that would meet required but not optional. Second was to use 15 characters with part identifying department or server and throw in email address on end, ect. this meets required and all optional.
Tool to identify a faulty network card- Protocol Analyzer
Frame relay is band width on demand
Token Ring to Ethernet transfer speed differences is because of FRAME SIZE DIFFERENCES not TCP window or speed of Ethernet.
Changing TCP window sizes will not reduce utilization by 50%. does not meet req.
On the questions with Macs and 95 clients. Macs can't use IPX or NWLINK so does not meet require.
High level file protocol is SMP if FTP is not offered. AFP is at presentation so is lower.
Measure bandwidth with Protocol Analyzer.
Question with client with dial up and what protocol could it be using choices are SLIP & PPP chose both.
UNC string remember computer/share
Password on shared resources is less administration than user.

I also had a question about a company having Cat 3 UTP cabling and they wanted 50% less network congestion while keeping the network activity at the same level. The selections included:
1. Change the frame size from 1,547 (or something like that) to 576
^^^^^ This would actually increase the network activity since packets are smaller
2. Change from UTP Cat 3 to Cat 5 and put in 100BASET and segment using routers.
^^^^^^^^ I chose this one. Even without the segmentation this would provide the required result because you are going from 10mbps to 100mbps.
