Frequently Asked Questions About Oracle MySQL 5.7 Database Administrator
The 1Z0-888 exam leads to the Oracle Certified Professional, MySQL 5.7 Database Administrator certification, a Professional-level credential from Oracle.

The Oracle MySQL 5.7 Database Administrator exam includes 75 questions and gives you 120 minutes to complete them. That works out to a fairly tight pace, so reading each question carefully but decisively matters more than perfectionism.

A practical benchmark: work through the 155 practice questions at Actualtests4sure until you can score comfortably above the passing line in timed mode, then schedule your exam.
