The 1Z0-082日本語 exam is the official test behind the Oracle Database 19c certification, a Associate-level credential from Oracle. Passing it validates the skills measured by the Oracle Database Administration I (1Z0-082日本語版) objectives and proves to employers that you can apply those skills in real-world scenarios, not just recite theory. The credential also sits alongside related certifications such as Oracle Certified Associate (OCA) - Oracle Database Administration 2019, making it a strong building block in a broader Oracle certification path. For candidates planning a longer-term career move, the 1Z0-082日本語 exam is often the step that turns study effort into a verifiable, resumé-ready qualification.
The Oracle Database Administration I (1Z0-082日本語版) blueprint is divided into 16 exam domains. The first three are Managing Users, Roles, and Privileges, Using Single-Row Functions to Customize Output, and Managing Schema Objects. The weightings matter: they tell you where the bulk of your score comes from, so allocate study time in proportion rather than spreading it evenly. Scroll back to the exam topics section above for the complete domain-by-domain breakdown of the 1Z0-082日本語 exam.
The Oracle Database Administration I (1Z0-082日本語版) exam gives you 150 minutes to work through 90 questions. Do the math before test day: divide the total time by the question count to set a steady per-question pace, and treat that number as a hard budget rather than a guideline. When a question eats more than its share, flag it and move on — a flagged question can be revisited, but lost minutes can't. Running two or three full timed mock exams in the ITExamDownload test engine before your exam date is the most reliable way to make that pacing automatic.
The passing score for the Oracle Database Administration I (1Z0-082日本語版) exam is 64%, and the official registration fee is $245 USD. Keep in mind that a failed attempt means paying that fee in full again — there are no discounted retakes — so booking the exam before you're ready is the most expensive shortcut in certification. A practical rule: take a timed self-assessment with ITExamDownload practice tests first, and only schedule your seat once you're scoring comfortably above the passing mark with time to spare. That buffer absorbs exam-day nerves and the handful of questions that always seem to come from nowhere.
According to Oracle, the Oracle Database Administration I (1Z0-082日本語版) exam uses the following question formats: Multiple Choice, Multiple Select. Different formats reward different habits. For scenario-based items, read the final sentence of the question stem first so you know what's actually being asked before you dig into the details, and never change an answer unless you can point to the exact clue you missed. The ITExamDownload question bank lets you rehearse every format until each one feels routine.

The credential you earn by passing the Oracle Database Administration I (1Z0-082日本語版) exam remains valid for Lifetime.
