The 1z0-078 exam is the official exam behind the Oracle Certified Professional, Oracle Database 19c: RAC, ASM, and Grid Infrastructure Administrator credential from Oracle. It sits at the Professional level of the Oracle certification track. It is also associated with Oracle Database Administration 2019 Certified Professional. The Actual4Dumps practice questions on this page map to the same objectives, so you can measure your readiness before you book a seat.
The 1z0-078 exam contains 77 questions and gives you 120 minutes to complete them. That pace leaves little room for getting stuck, so train yourself to flag a hard question, move on, and circle back later. Run at least one full timed session in the Actual4Dumps test engine a week before your exam date to check whether your pacing holds under pressure.
You need 65% to pass the 1z0-078 exam, and the official registration fee is USD 245 (varies by region). A retake means paying that fee again in full, which makes thorough preparation the cheaper option by far. Before scheduling, take a timed Actual4Dumps practice test; if you are not scoring comfortably above the passing line, give yourself more study time instead of booking on hope.
