Oracle Database 12c: RAC and Grid Infrastructure Administration (1z1-068日本語版) is an official Oracle certification exam, listed under the code 1z1-068日本語. Clearing it earns the 12c certification, a Expert (Oracle Certified Expert)-level credential. It also ties into Oracle Certified Expert, Oracle Database 12c: RAC and Grid Infrastructure Administrator, 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 90 questions in 150 minutes on the Oracle Database 12c: RAC and Grid Infrastructure Administration (1z1-068日本語版) 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 12c: RAC and Grid Infrastructure Administration (1z1-068日本語版) requires Section-based (e.g., ~60% / 45% / 33% by section reported), and the official registration fee is USD 245 (approx.). Remember that a retake bills the same USD 245 (approx.) 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.
