The Oracle 1Z0-083 Exam, Question by Question
Oracle Database Administration II is an official exam run by Oracle under exam code 1Z0-083. Passing it awards the Oracle Database 19c certification, which sits at the Professional tier. It also counts toward related credentials such as Oracle Database Administration 2019 Certified Professional, Oracle Database Administration Certified Associate. Certified professionals remain in shorter supply than the market wants, which is precisely why this exam keeps showing up in conversations about better roles and better pay.
The Oracle Database Administration II exam gives you 120 minutes to work through 68 questions. That is a tight ratio, and it punishes candidates who get emotionally attached to any single item. The fix is mechanical: answer what you know, flag what you do not, and keep moving. A few full-length timed runs in the Actual4Exams test engine, with its randomized question order, will calibrate your pace far better than untimed reading ever could.
The official fee for Oracle Database Administration II is USD 245, and 57% is what passing takes. The uncomfortable part: retakes cost the full USD 245 again, which makes preparation the cheapest line item in this whole project. Before booking, put yourself through repeated scored sessions with the Actual4Exams practice tests and compare results over time; a stable margin above the passing line, not a single lucky run, is when you are ready.
Oracle Database Administration Certified Associate credential is recommended before pursuing the Professional certification.
Vendor rules do get revised, so treat this as your starting point and confirm the current eligibility details before booking via the official exam page.
