Oracle certification tests are administered by Sylvan Prometric at local sites throughout the USA and overseas.
Each computer-delivered certification test challenges candidates to demonstrate their knowledge and experience by answering 60-70 multiple-choice questions in the space of 1.5 hours. Most of the multiple-choice questions are straightforward and have been carefully screened to remove those that are superfluous or misleading. Some questions even provide "what if?" scenarios, but these constitute a small portion of the exam and are often presented as multiple-correct multiple-choice questions.
By requiring a series of these tests for each job-related certification track, Oracle can verify that a candidate has both the knowledge and experience required to administer an Oracle database successfully The next lesson describes some strategies you can employ to help you pass the tests.
