Common Questions About the Oracle 1z1-068 Exam

What is the Oracle Database 12c: RAC and Grid Infrastructure Administrator exam all about?

The 1z1-068 exam is the official Oracle exam behind the 12c certification, validating the skills measured by the Oracle Database 12c: RAC and Grid Infrastructure Administrator credential. It sits at the Expert (Oracle Certified Expert) level of the Oracle certification program. It also connects to Oracle Certified Expert, Oracle Database 12c: RAC and Grid Infrastructure Administrator, so the knowledge you build here carries over to those tracks as well.

How many questions are on the 1z1-068 exam, and how much time do I get?

The 1z1-068 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 1z1-068 exam, and what does it cost?
