1Z0-898 Exam Essentials: Your Questions Answered
The Oracle Java EE 6 Java Persistence API Developer Certified Expert exam spans 5 domains, and they are not weighted equally.

The 1Z0-898 exam is Oracle's official certification test, and passing it earns the Oracle Solaris credential at the Expert level. In career terms, it is verified proof of skill — the kind that moves you up the shortlist when your company works with Oracle technologies, or when you apply to one that does. The same track also includes Oracle Certified Professional, Java EE Developer, Oracle Java SE certifications, Java EE 6 Developer certification track, so this exam can anchor a longer certification plan.
You pass the Oracle Java EE 6 Java Persistence API Developer Certified Expert exam at 70%, and each attempt costs 245 USD — fail, and that fee is due again in full for the retake. Treat mock exams as insurance: keep practicing with Lead2Passed until your scores sit comfortably above 70% twice in a row, then schedule the real 1Z0-898 exam.
Please do. Lead2Passed offers a free demo download for the Oracle Java EE 6 Java Persistence API Developer Certified Expert exam — grab it from the product page or leave your email and we will send it over. Purchases come with 365 days of free updates; after that year, extending the update service costs 50% of the original price in your member zone.
The Oracle Java EE 6 Java Persistence API Developer Certified Expert exam packs 60 questions into 120 minutes. That ratio leaves almost no room for stalling, so time management is a trained skill, not luck. Our suggestion: rehearse full-length timed sessions in the Lead2Passed engine, learn to park a question and return later, and walk into the 1Z0-898 exam with a pacing plan already rehearsed.
Strong knowledge of Java EE 6, JDBC, and relational database concepts recommended Since Oracle revises these rules from time to time, confirm the current prerequisites on the official exam page (https://education.oracle.com/) before booking your Oracle Java EE 6 Java Persistence API Developer Certified Expert exam.

Not covered: attempts within 3 days of purchase, exams never actually taken, free materials, and expired orders — and the candidate name must match the payer name. Prefer material over money?
