Hi Ranchers

Tonight, I took the IBM 340 pre-assessment test in order to get the free voucher. Previously I searched for those questions at JavaRanch but surprisingly Prometric asked some brand new ones (20 - almost half of the required questions).

Fortunately I passed because I was studying this subject and I was able to answer some of these questions, Below, I listed all of them:

These are not new questions. Most of them were part of my pre-assessment test for 340.

Probably I was unlucky, because I found two threads at JavaRanch about IBM 340 pre-assessment test but none of them with those questions
