Common Questions About the Oracle 1z1-084 Exam

What is the Oracle Database 19c Performance and Tuning Management exam all about?

The 1z1-084 exam is the official Oracle exam behind the Oracle Database 19c certification, validating the skills measured by the Oracle Database 19c Performance and Tuning Management credential. It sits at the Professional level of the Oracle certification program. It also connects to Oracle Database 19c Performance Management and Tuning Certified Professional, so the knowledge you build here carries over to those tracks as well.

How many questions are on the 1z1-084 exam, and how much time do I get?

The 1z1-084 exam contains 55 questions to be completed within 90 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the Getcertkey test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.

What score do I need to pass the 1z1-084 exam, and what does it cost?

The passing score for the 1z1-084 exam is 60%, and the official registration fee is $245 USD. Retakes are not discounted — every new attempt means paying the full fee again — so it pays to measure yourself before you book. Work through the 57 practice questions on Getcertkey, sit a timed practice test, and schedule your exam only when your scores are consistently comfortable. That simple habit is the cheapest exam strategy there is.

Are there any prerequisites for the 1z1-084 exam?

Candidates should have experience with Oracle Database administration and SQL tuning concepts. Requirements can change when Oracle revises its certification program, so confirm the current eligibility rules on the official exam page before you register.

Can I try the 1z1-084 practice questions before I buy?

Yes. Getcertkey provides a free 1z1-084 PDF demo so you can review the question style and answer quality before purchasing. Every purchase also includes 365 days of free updates — if Oracle revises the exam during that period, the updated material reaches you at no cost. Once the free-update year ends, you can extend your update service at a 50% discount.

What if I fail the 1z1-084 exam, and how is my order delivered?

Every Oracle Database 19c Performance and Tuning Management purchase on Getcertkey is covered by a 100% money-back guarantee with clear conditions: if you take the corresponding exam within 60 days of your purchase and do not pass, you can claim a full refund by submitting a scanned copy of your exam enrollment slip and your official score report as a PDF within two days of the exam date; claims are processed within seven days of submission. The guarantee does not apply to exams taken within three days of purchase, to material that was downloaded but never used in an exam attempt, or to free products and expired orders, and the candidate name must match the payer name. If you would rather not take a refund, you can instead exchange your purchase for two free exam preparation products of equal value and keep the update service on your original product.
