The 1Z0-023 exam, officially known as Oracle Architecture and Administration, is the Oracle test that leads to the Oracle Certified Professional (Legacy) certification at the Professional level. Passing it validates the skills employers expect from a certified professional. It is also associated with related credentials such as Oracle Database Administrator Certified Professional (Legacy Track).

The 1Z0-023 exam contains 86 questions, and you have 90 minutes to complete them. Work out your per-question pace before test day, and flag slow items instead of stalling on them — time pressure, not knowledge, sinks many first attempts. Timed mock exams in the Actual4Exams test engines are the most reliable way to build that rhythm.

The passing score for the 1Z0-023 exam is 70%, and the official registration fee is USD $195 - $245 (historical, no longer available). If you miss the mark, a retake means paying the full fee again, so book your seat only when you are ready. A practical benchmark: score consistently above the passing line on timed practice tests before scheduling the real exam.
