The Oracle MySQL 8.0 Database Administrator FAQ — Read This Before Registering

The Oracle MySQL 8.0 Database Administrator blueprint has 5 domains, led by MySQL Architecture & Installation, Security & User Management, Monitoring & Maintenance. Think of the weightings as the vendor's hint about where points concentrate — plan your hours accordingly. The complete outline above lists every subtopic.

Passing the 1z1-908 exam earns you the MySQL Database Administration certification at the Professional level — Oracle's official verification of your skills. It's considered important because it's genuinely difficult, which is exactly why it carries weight with employers. Related credentials include Oracle Certified Professional, MySQL 8.0 Database Administrator.

75 (approx.) questions in 120 minutes. That combination rewards candidates who've trained their pace, not just their memory — so before the real thing, run full timed sessions in the PassTorrent engine, practice flagging hard questions instead of fighting them, and learn what your sustainable per-question rhythm feels like.

Delivery is instant: successful payment triggers an automatic email with your product, arriving in about a minute — install on unlimited computers, and if 2 hours pass with nothing, our 24/7/365 customer service will fix it fast. The guarantee: take the corresponding 1z1-908 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 100% refund processed within 7 days. Exclusions: exams within 3 days of purchase, name mismatches between candidate and payer, and free or expired products. Prefer a swap? Take two equal-value exam products free, updates intact.

Recommended hands-on experience with MySQL administration Before paying any registration fee, verify the current criteria on the official exam page — official 1z1-908 exam page — since vendors do revise their rules.

The official fee is USD $245, with 60% (approx.) required to pass. Both numbers matter more together: the fee is per attempt, so every retake costs the full amount again. Drilling the 142 practice questions from PassTorrent until you're comfortably past the mark is the fiscally sound approach.

Yes — the free demo gives you several real questions and answers from the set, so you can see whether it interests you and helps you before spending anything. Once you buy, updates are free for 365 days — new versions are mailed to you automatically — and an expired update period renews at 50% off.
