Common Questions About the Oracle 1Z0-082日本語 Exam
What is the Oracle Database Administration I (1Z0-082日本語版) exam all about?
The 1Z0-082日本語 exam is the official Oracle exam behind the Oracle Database 19c certification, validating the skills measured by the Oracle Database Administration I (1Z0-082日本語版) credential. It sits at the Associate level of the Oracle certification program. It also connects to Oracle Certified Associate (OCA) - Oracle Database Administration 2019, so the knowledge you build here carries over to those tracks as well.
How many questions are on the 1Z0-082日本語 exam, and how much time do I get?
The 1Z0-082日本語 exam contains 90 questions to be completed within 150 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the Getcertkey test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.
What score do I need to pass the 1Z0-082日本語 exam, and what does it cost?
The passing score for the 1Z0-082日本語 exam is 64%, and the official registration fee is $245 USD. Retakes are not discounted — every new attempt means paying the full fee again — so it pays to measure yourself before you book.

That simple habit is the cheapest exam strategy there is.
