Oracle 1z1-072 Exam FAQ: Answers Before You Buy

Oracle Database 12cR2 Administration is an official Oracle certification exam, listed under the code 1z1-072. Clearing it earns the Oracle Database Administrator (Oracle Database 12c) certification, a Associate-level credential. It also ties into Oracle Database Administrator Certified Associate (OCA), Oracle Database 12c Administrator Certified Professional (OCP), which makes it a useful anchor for a longer certification plan. For employers, the value is simple: the vendor itself has verified what you know.

You will work through 70–80 questions in 120 minutes on the Oracle Database 12cR2 Administration exam. The content is only half the battle; the clock is the other half. Train both at once: set the ValidDumps test engine to full timed mode, practice skipping and returning to stubborn items, and repeat until finishing with minutes to spare feels normal rather than lucky.

Passing Oracle Database 12cR2 Administration requires ~65%, and the official registration fee is $245 USD (may vary by region). Remember that a retake bills the same $245 USD (may vary by region) all over again, so winging it is the most expensive strategy on the table. A better approach: benchmark yourself with the ValidDumps practice tests first, and schedule the real exam only once your scores sit comfortably and consistently above the requirement.

Basic knowledge of Oracle Database administration and SQL recommended. No strict official prerequisite, but foundational SQL knowledge is expected.

Requirements do evolve, so before you spend a registration fee, verify the current conditions on the official exam page.
