SUN 310-084 exam question

As IT certifications becoming more and more popular, we decided to have a try, just to make more money, and make ourselves more competitive in this society.

We took the 310-084 exam, but when we saw the large quantities of study materials, we became a little anxious. We studied day and light till someday I felt that we could not capture the main points of the real test, so I entered the professional SUN forum to copy others experience.
