The Oracle Database Administration I (1z0-082 Korean Version) (exam code 1z0-082 Korean) is the exam you pass to earn the Oracle Database 19c certification, a credential at the Associate level. It is also connected with related credentials such as Oracle Certified Associate (OCA) - Oracle Database Administration 2019. If you are mapping out a certification path with Oracle, this exam is a milestone worth planning around.
The 1z0-082 Korean exam includes 90 questions, and you have 150 minutes to complete them. With that many questions on the clock, pacing is part of the challenge: divide your time into rough blocks as you go, and flag the items that stall you so you can circle back at the end instead of burning minutes on a single question. A week or two before your exam date, sit at least one full timed session in the ActualTestsQuiz test engine under the same time limit, so the pace feels familiar rather than frantic on the day.
You need 64% to pass the 1z0-082 Korean exam, and the official registration fee is $245 USD. That fee is due again in full for every retake, which makes thorough preparation the cheaper investment by far. Before you book your seat, test yourself with the ActualTestsQuiz practice questions until you are scoring comfortably above the passing mark on a consistent basis — it is the simplest way to avoid paying for the same exam twice.
No mandatory prerequisite; basic knowledge of SQL recommended.
