FAQ: Preparing for Oracle Database Administration I (1Z0-082日本語版) the Smart Way
Oracle Database Administration I (1Z0-082日本語版) is an official exam run by Oracle under exam code 1Z0-082日本語. Passing it awards the Oracle Database 19c certification, which sits at the Associate tier. It also counts toward related credentials such as Oracle Certified Associate (OCA) - Oracle Database Administration 2019. 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 I (1Z0-082日本語版) exam gives you 150 minutes to work through 90 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 I (1Z0-082日本語版) is $245 USD, and 64% is what passing takes. The uncomfortable part: retakes cost the full $245 USD 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.
No mandatory prerequisite; basic knowledge of SQL recommended.
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.
It is. Actual4Exams publishes a free PDF demo of the Oracle Database Administration I (1Z0-082日本語版) material, so the product can prove itself before you pay.

If you take the Oracle Database Administration I (1Z0-082日本語版) exam within 60 days of purchase and fail, you qualify for a full refund, provided the exam corresponds to your product.

You may also choose an exchange instead of a refund: two other exam products of equal value, free, with the update service on your original purchase retained.
