The Oracle 1Z0-027 Exam, Question by Question
Oracle Exadata X3 and X4 Administration is an official exam run by Oracle under exam code 1Z0-027. Passing it awards the Oracle Certified Expert (OCE) - Exadata X3 and X4 Administration certification, which sits at the Professional tier. It also counts toward related credentials such as Oracle Database Administrator Certified Professional (OCP), Oracle Exadata Database Machine Administration, Oracle Exadata Database Machine X5 and newer certifications. Certified professionals remain in shorter supply than the market wants, which is precisely why this exam keeps showing up in conversations about better roles and better pay.
The Oracle Exadata X3 and X4 Administration exam gives you 120 minutes to work through 60-80 questions. That is a tight ratio, and it punishes candidates who get emotionally attached to any single item. The fix is mechanical: answer what you know, flag what you do not, and keep moving. A few full-length timed runs in the Actual4Exams test engine, with its randomized question order, will calibrate your pace far better than untimed reading ever could.
The official fee for Oracle Exadata X3 and X4 Administration is USD 245 (may vary by region and tax), and Unknown (Oracle does not publicly standardize a fixed passing percentage for this exam) is what passing takes. The uncomfortable part: retakes cost the full USD 245 (may vary by region and tax) again, which makes preparation the cheapest line item in this whole project. Before booking, put yourself through repeated scored sessions with the Actual4Exams practice tests and compare results over time; a stable margin above the passing line, not a single lucky run, is when you are ready.
Recommended: Oracle Database Administrator experience (OCP level) and familiarity with RAC and ASM concepts
