Novell network paper

The paper consists os three sections.

1. aptitude 15 questions 20 min.

2. system concepts 20 questions 20 min.

3. 'c' 15 questions 20 min.

NOTE:::::

I'm sendin the questions, somany have no answers. U do check the

answers for all the given questions also.

All questions are MULTIPLE CHOICES ONLY.

U do try to cover the related topics to get some understanding.

In interview They are asking C C++ Operating system concepts

and Networks.

They will ask about Ur interesting subjects, U try to have good

grip on those intresting subjects.

They selected 11 out of 55 students.

They asked about c c++ project work and OS,NETWORKS.

But they selected only 2 , one from CS and another is BTech ECE.

SECTION 1 is main factor selection to the interview

--------------------------------------------------------------

In the interveiw you should be very active .And should be frank to say

no also.One CS student said that he don't know NETWORK and he hasn't

taken NETWORKS subject.But he has selected.

OK BEST OF LUCK.
