Oracle 1Z1-160 Exam Questions Answered
The 1Z1-160 exam leads to the Oracle Database Cloud Service Operations Certified Associate certification from Oracle. It is positioned at the Associate level. The exam validates the knowledge and skills expected of candidates preparing for Oracle Database Cloud Service.
Related certifications include:
- Oracle Database Cloud Administrator Certified Associate
- Oracle Database Cloud Administrator Certified Professional
The 1Z1-160 exam includes 70 questions and allows 120 minutes. Before test day, divide the available time by the number of questions in a timed practice set to establish a steady per-question pace. If a difficult item starts consuming too much time, mark it for review and move forward instead of losing momentum. A full timed practice session can help you decide when to move on, when to return, and how much buffer to reserve for a final check.
The passing score for 1Z1-160 is 63%, and the official exam fee is USD $245. Because a retake requires paying the exam fee again, use timed practice results as a readiness check before scheduling your next attempt. If your performance remains inconsistent, continue reviewing weak domains and repeat a timed session before booking the exam.
