Hi Preeti,
There are two privacy questions at the beginning of the exam. One asks you not to reveal the exam questions to others. If you don't agree you'll be unable to continue with the exam.
There is a general explanation of the exam wording, etc on the Sun's site
http://suned.sun.com/USA/certification/register/policies.html so you can read them before you take the exam.
Hope that helps.
Good luck on the exam
