The Oracle 1z1-908 exam, officially titled MySQL 8.0 Database Administrator, is the required test for earning the MySQL Database Administration certification, a credential at the Professional level. Passing it validates the skills Oracle expects from certified professionals, and it can also support progress toward related credentials such as Oracle Certified Professional, MySQL 8.0 Database Administrator.
The 1z1-908 exam includes 75 (approx.) questions, and you have 120 minutes to complete it. Before exam day, divide the available time by the question count so you know the pace you need to hold, and practice flagging time-consuming items for review instead of stalling on a single question. Timed sessions in the Actualtests4sure test engine are the easiest way to build that rhythm before it counts.
You need 60% (approx.) to pass the 1z1-908 exam, and the official registration fee is USD $245. Keep in mind that a failed attempt means paying that fee in full again for a retake, so avoid booking your seat on a hunch. Work through the Actualtests4sure practice test until your scores sit comfortably above the passing requirement before you schedule the exam.
Oracle asks candidates to meet the following requirement before registering: Recommended hands-on experience with MySQL administration. Exam policies do change, so confirm the latest details on the official exam page at https://education.oracle.com/mysql-80-database-administrator/pexam_1Z0-908 before you book.
