Subject: Net Essentials

I passed my Net Essentials with a 982. Dropped one somewhere in the trouble shooting section.

I would like to thank you all for the 'dumps'.

I would also like to caution everyone on taking these dumps word for word...many questions are not phrased the same, and many answers are not correct.

My suggestion is to use these dumps so you know what to expect on the test, but then go and study the material covered in the questions.

As the other dumps say, you must know:

Which protocols are routable, which are not.

What layer of the OSI model that devices run at, Gateway, Router, Brouter,

Bridge, Repeater, etc. I had only 1 question on 802.x

Know your WAN protocols - speed, reliability, etc.

Know your cable types, speeds and lengths.

Actually, pretty well everything is covered in these dumps. There is a long

one called 'Questions' that is good to go through and answer.

One point I did really want to make, and the reason I am sending this, is:

Where on earth did that crazy formula for multiple modem speeds come from?

Please THINK when reading these dumps and answers.

If you see a formula like

n * m * 100 / 8

where n is the number of modems and m is the modem speed,

and this formula is supposed to give you the aggregate link speed,

try putting in ONE modem. i.e.:

1 * 28.8 * 100 / 8.

Does that make any sense?

Why multiply by 100 then divide by 8? This would magically make this modem

12.5 faster than it really is. Wow, where do I buy one?

Now, one could divide by 8 to get bytes per second instead of bits per

second, but line speed is usually expressed in bits, not bytes. And why

multiply by 100? Beats me!

Moral: Think, don't memorise!

Lastly, be prepared to wade through quite a surprising number of scenario questions. Seemed to me there were more scenarios on this test than there were on any of the other four I have done.
