The 1Z0-1089-20 exam is the official Oracle exam behind Oracle Cloud Infrastructure 2020 HPC and Big Data Solutions Associate — passing it earns you the Oracle Cloud Infrastructure 2020 HPC and Big Data Solutions Associate certification, a credential positioned at the Associate level. It is built for candidates who want to validate the skills measured by Oracle Cloud Infrastructure 2020 HPC and Big Data Solutions Associate. Depending on your track, the exam is also linked to the Oracle Cloud Infrastructure Foundations Associate and Oracle Cloud Infrastructure Architect Associate certifications, so one pass can move you toward more than one Oracle credential.
The 1Z0-1089-20 exam presents 55-60 questions to be completed within 90 minutes. That pace leaves little room for second-guessing: read each question carefully on the first pass, flag the ones you want to revisit, and keep moving instead of stalling on a single item. Before exam day, run at least one full timed session in the TestSimulate desktop or online test engine with a comparable question load — a steady rhythm under the clock is a trainable skill, and it is often what separates a pass from a near miss.
To pass the 1Z0-1089-20 exam you need Approximately 68%, and the official registration fee is $245 USD (may vary by country). Keep in mind that a failed attempt means paying that fee again in full — retakes are not discounted. Given the cost, self-test before you book: if you can score comfortably above the passing mark on two or three consecutive timed TestSimulate practice tests, your budget is far better spent on the exam itself than on a retake.
No formal prerequisite required; recommended familiarity with Oracle Cloud Infrastructure fundamentals. Because Oracle revises its certification programs from time to time, treat this as a starting point rather than the final word. Confirm the current eligibility requirements on the official Oracle exam page before you register.
