Networking Essentials:70-058

Status: Pass (862/1000)

Exam date 15/4/98

Robert here is my 20 cents worth of contribution to your site.

I took the exam yesterday and it turned out not so bad after all. I was expecting a higher score, so in that sense I was a bit disappointed.

Resources used:

ExamCram, Microsoft Self Study Kit, Brain Dumps, and all free testing/demo software available on the Inernet.

One other very helpful site (besides this one) is:

www.visualmcp.com/ne take the trial test (3 test available). I had atleast 5-10 question from these test that I can remember. Thanks to whoever mentioned about this site in their Brain Dump before.

Read the Glossary Section, it offers a chance to pick-up easy 100% on Standards and Technology definations.

Pay close attention to the following definations:

Client Server

NDIS /ODI (lots of people have commented on weird wordings etc)

802.3, 802.5

Routing, RIP

NetBios, NetBeui

SMB. Also a question, identify high level protocol (SMB)

Redirector

don't stop here, read the rest of the glossary anyway.

You don't need to memorise them, but if you see a part of it reproduced in the options, you should be able to identify it.

eg, IEEE

The glossary defination is a paragraph long, but this part sentence if recognised in the options should help you pick the right answer:

"...defines LAN standards for the Physical and Data Link layers of the OSI model."

eg NDIS

"...it offers protocol multiplexing so that multiple protocols stacks can be used at the same time"

In plain English this translates "NDIS allows multiple protocol to be binded to a single network interface card".

I hope you get the idea.

OK, let me fill you in on the scenario questions.

I was scared before the test, and convinced that these will destroy me, but I was lucky, I got a few which were fairly straight forward, I still don't know if I got them right. Who cares, I passed.

As suggested earlier by many people mark them and do it later, but there is only one catch,

if you run out of time (you need at least 30 to 35 minutes) you will be pushing to pass the exam.

A typical Scenario will be:

A LAN is experiencing a heavy broad cast traffic

Required: To reduce the broadcast traffic by 50%

Optional: To eliminate the broadcast

Allow the segment be able to extended

Rectify any signal attenuation

Proposed Solution:

Use a Bridge to segment the network

Answer: The proposed soluiton does not producethe Required result.

Try rephrasing the above scenario by having Router, Bridge, Brouter and see if you understand how it will change the results.

Note:

Before you work out the answers you must remember these facts:

Routers don't allow broadcast to pass through, and hence rectify the broadcast storm problems.

Repeaters and Bridges will let the broadcast pass through

Brouters will allow the broadcast to pass through if the bridging is enables, if disabled will only allow routing protocol to pass through and no broadcast. (remember Netbui in non-routable)

There were two standard scenario question (3 cities) that uses

a) 2 T1 lines, would like to connect a to b to c

Required: 1.5 Mbs WAN connection

Optional Fault Tolerance, if one link is broken, the connectivity should be maintained

b) Same scenario except this time use 3 T1 lines

Answer

a) The proposed Solution produces the required results but not the optional results

b) The proposed Solution produces the required result and all the optional results.

One more scenario, this time with RAS, 16 connections, using 28.8 modems etc

Requried 1.5 Mbs WAN connections

Options: Be able to continue if part of the connection is dropped etc

Ans: Does not produce the Requied results

To get 1.5 Mbs you need T1 connections and remember 28.8 x 8 = 230kb, which is no where near the 1.5Mbs which was required.

2-3 standard questions on COM and LPT, IRQ's related question, very straight forward if you knew your IRQ's. Write all the IRQ's and the cabling details down during the 15 minutes allocated for the practise test. This proved to be of great help to me in the test.

2 questions on PPP and SLIP, but it had choices such as Data compression, Dynamic IP addressing etc, PPP was the correct answer in both the cases.

4-5 on Protocol Analyser. Having reading the comments from the Brain Dump, I did not even bother reading the full question but simply choose PA.

1 on ATM, 100Mhz and higher (ATM)

1 question on SNMP, what would you use to manage and monitor Routers, Bridges etc. The key word here was manage. In the option there was Protocol Analyser as well, but I choose SNMP.

1 question on ISDN, it will replace the standard phone lines in the future.

One question which referred to bandwith on demand (it had both ATM and Frame Relay as options. Ans Frame Relay) this is the only time you will not pick ATM.

2-3 questions on User level and Share level securities

Which of the following offer share level security

1. Win95

2. WFW

3. NT Server

4 NT Workstation

The correct answer is 1 and 2.

Remember, Microsoft's shared level securities defination is that a shared level security is guarded by using a password. NT Workstation and NT Server do share resources but there is no use of passwords, instead you can add users names that can access these resources. Therefore it is User level security.

3-4 Trouble shooting questions:

A network layout shown (exhibit) like a T segment, where each end was terminated. Obviously with a BUS topology you only have one segment where two ends are terminated using the 50 Ohms terminators. eg

50 ohm terminator_______*_______*_______*_______50 ohm terminator.

Another scenario (exhibit) where two sets of bus segments were joined by a bridge/router but each segment was shown to be grounded at both the ends.

This is incorrect, since on every segment there should be only one grounding at one end of the segment only.

Another Trouble shooting question:

Two table were displayed that contained IRQ, Port # and two sets of identical MAC address, as a result both the nic did not work. It was clearly stated that there was no IRQ conflict, since no other device was using these IRQ's.

The options were

change the IRQ from 5 to 3 etc (not applicable)

change the port address from 300 to 320 (not applicable)

re-install the Operating System (not applicable)

reset the nic to factory settings (this is the correct answer, because by resetting, both cards will have two unique MAC addresses. (remember through s/w settings you can change MAC addresses)

Another question on selecting the correct protocol

A Peer to Peer network consisting of 5 pcs, which protocol whould you select

DLC

Nwlink/Ipx

TCP/IP

XNS

I choose Nwlink/Ipx. (If NetbBeui was a option, I would have selected NetBeui)

Know the cabling requirement back to front, eg which cables used for 100BaseT - CAT5.

Which cables uses BNC-T connectors. (10Base2, Thinnet)

Which cable is the cheapest (UTP)

Which cable can connect two LAN spread over 1000 meters (Fibre Optics)

I question on X.25, what protocol would you use to transfer data in a unstable environment. The option from memory were

ATM

Frame Relay

ISDN

X.25

The correct answer is X.25, because it is big on error checking, hence very slow.

That's all I can remember for now.

I would like to thank all those who took the time and effort to contribute their BD's on this site, and a big Thankyou to Robert for maintaining this wonderful site.

All the best to everyone, if you fail, then don't worry.

"Remember it is better to try and fail than not to try at all." Success will definately follow in the next round. The trick is to work smarter not harder.

3 down, 3 to go, next exam will be TCP/IP followed by Enterprise.
