Common Questions About the Oracle Database 19c: RAC, ASM, and Grid Infrastructure Administration Exam
The Oracle Database 19c: RAC, ASM, and Grid Infrastructure Administration (exam code 1z0-078) is the exam you pass to earn the Oracle Database certification, a credential at the Professional level. It is also connected with related credentials such as Oracle Database Administration 2019 Certified Professional, Oracle Certified Professional (OCP) - Oracle Database 19c. If you are mapping out a certification path with Oracle, this exam is a milestone worth planning around.
The 1z0-078 exam includes 77 questions, and you have 120 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 2Pass4sure test engine under the same time limit, so the pace feels familiar rather than frantic on the day.
You need 65% to pass the 1z0-078 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 2Pass4sure 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.
Oracle recommends hands-on experience with Oracle Database 19c, RAC, ASM, and Grid Infrastructure administration. This exam is commonly pursued as part of the Oracle Database Administration 2019 Certified Professional credential path.
Eligibility rules can be adjusted by Oracle over time, so before you register, confirm the current requirements on the official exam page: view the official 1z0-078 exam information.
