Hi Rana,
Below are my (did I say *MY*..) answers. Others could correct the answers if any.
1) iii
I guess the choices could have been
"Browsers,admins and users" ...
Browsers can't give access to system privileges.
So my choice was iii)
2) 2
SSL is used for encrypting the physical data.It sits on the top of application protocol and below the level of TCP/IP protocol.
3) 1
This is obvious.
4) 1
5) 1
6) 2
Http with java is used for java tunneling to pass on other protocols through the standard http port 80.
7) 1
Option 2 basically tells about the design of DATABASE not about the application.
8) 4
RMI and CORBA are distributed object architectures,and they work with interfaces which are being implemented by stubs and skeletons.
They are the object references.
9) 3
let's see which are the answers which don't fit in to the scenario:
1) Volatile client app ==> The application is brittle,so changes are required although might not be in JAVA.
2) Multiple client platforms ==> Java supports this.
3) Experience in 4GL ==>
(Learnt a new thing.That java is a third gen. lang.)
Take a quick look at this.
http://www.webopedia.com/TERM/F/fourth_generation_language.html
4) Experience Database design ==> Nothing to do with the question
5) Experience in Smalltalk ==> Should be easier to learn java if one knows smalltalk.
So the answer is (3)

10) 4
11) c
cheers,
