1Z0-888 Exam FAQs — Read Before You Register
No mandatory prerequisite exams; recommended 6-12 months hands-on experience with MySQL 5.7 Eligibility details like these are worth double-checking before you register — vendors revise them periodically, and the official exam page (official 1Z0-888 exam page) always has the current version.
The official Oracle MySQL 5.7 Database Administrator outline has 7 domains — the biggest include User and Access Management (10%), MySQL Security (15%), MySQL Architecture and General Administration (15%). Those weightings are your study compass: the largest domains hide the most points. See the full outline above for every subtopic.
You can, and you should. The free PDF demo is there so you can judge the content yourself before spending anything. If you're unsure whether the PDF, desktop engine, or online version suits your study habits, contact our 24/7 service team — they'll advise you. After purchase, 365 days of free updates are included, renewable at 50% off if the period ever expires.
Sign up through the vendor's official channels:
The exam is offered In-person at Pearson VUE test centers or online proctored exam, so decide which arrangement suits you before picking a date.
Delivery first: the moment you pay, we send the download link and access details to your email within a minute — even on holidays — and the files install on unlimited computers; contact support if 2 hours pass with nothing. For refunds, the terms are explicit: take the corresponding 1Z0-888 exam within 60 days of purchase, and if you fail, submit a scanned enrollment slip plus the official Score Report PDF within 2 days of the exam for a full refund, processed within 7 days. Excluded: exams taken within 3 days of purchase, name mismatches between candidate and payer, and free or expired products. The alternative to a refund: two equal-value exam products free, with your original updates intact.
The pass mark is 58%, and the official fee is USD $245. That fee resets to full price on every retake, so the real money-saver is preparation — run the 155 practice questions from Exam4Labs until passing becomes routine, then book your seat.
The vendor recommends:
Classroom hours alone won't tell you if you're ready — the 1Z0-888 practice questions from Exam4Labs will. Use them after the coursework to convert knowledge into exam performance.
The Oracle MySQL 5.7 Database Administrator is Oracle's official exam for the Oracle Certified Professional, MySQL 5.7 Database Administrator certification, a Professional-level credential. Candidates take it to validate real skill — and employers read it exactly that way. It also connects to related credentials such as Oracle Certified Professional, MySQL 8.0 Database Administrator (1Z0-908).
The exam gives you 120 minutes for 75 questions. The candidates who struggle aren't usually short on knowledge — they're short on pacing. Fix that before test day: set a time budget per question, practice moving past hard items without stalling, and rehearse full timed sessions in the Exam4Labs engine until the clock stops being a factor.
