Common Questions About the Oracle 1z0-485 Exam
What is the Oracle Exadata Database Machine 2014 Implementation Essentials exam all about?
The 1z0-485 exam is the official Oracle exam behind the Other Oracle Certification certification, validating the skills measured by the Oracle Exadata Database Machine 2014 Implementation Essentials credential. It sits at the Professional level of the Oracle certification program. It also connects to Oracle Certified Implementation Specialist - Oracle Exadata Database Machine, so the knowledge you build here carries over to those tracks as well.
How many questions are on the 1z0-485 exam, and how much time do I get?
The 1z0-485 exam contains 70-80 questions to be completed within 120 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 1z0-485 exam, and what does it cost?
The passing score for the 1z0-485 exam is 60-65%, and the official registration fee is USD 245 (may vary by region). Retakes are not discounted — every new attempt means paying the full fee again — so it pays to measure yourself before you book. Work through the 71 practice questions on Getcertkey, sit a timed practice test, and schedule your exam only when your scores are consistently comfortable. That simple habit is the cheapest exam strategy there is.
Are there any prerequisites for the 1z0-485 exam?
Recommended experience with Oracle Database administration, ASM, and RAC environments before attempting the exam. Requirements can change when Oracle revises its certification program, so confirm the current eligibility rules on the official exam page before you register.
