The Oracle Database 12c: Installation and Administration exam is the official Oracle test registered under exam code 1z1-062. Passing it earns you the Oracle Database certification, a credential at the Oracle Certified Associate (OCA) level. It is also linked to the related certifications: 1Z0-061 Oracle Database 12c: SQL Fundamentals, 1Z0-063 Oracle Database 12c: Advanced Administration. Oracle exams are valued because they test job-ready skills, so a passing score here carries real weight on a resume.
The Oracle Database 12c: Installation and Administration exam includes 67 questions to be completed within 120 minutes. Do the pacing math before exam day: with that many items on the clock, you need a steady rhythm and the discipline to flag a hard question and move on instead of stalling. Two or three full timed sessions with the ActualCollection test engine will show you exactly what that pace feels like, so time pressure stops being a factor on the real day.
To pass the Oracle Database 12c: Installation and Administration exam you need 64%, and the official registration fee is Varies by country (approximately USD $245). A retake is not discounted: a failed attempt means paying the full Varies by country (approximately USD $245) again, so treat your first sitting as the expensive one. A sensible rule is to book your seat only after you are scoring comfortably above the passing mark on the ActualCollection practice tests, not just squeaking past it once.
