1z1-078 FAQ Hub for 2026 Test-Takers
To pass the 1z1-078 exam you need Approximately 60% (Oracle scaled scoring may apply), and the official registration fee is USD 245 (may vary by region). Since a failed attempt is not discounted — retaking means paying USD 245 (may vary by region) in full again — treat the booking as the last step, not the first. Work through the Lead2PassExam practice questions until your timed scores sit comfortably above Approximately 60% (Oracle scaled scoring may apply), and only then lock in your exam date.
The 1z1-078 (Oracle Database 19c: RAC, ASM, and Grid Infrastructure Administration) is the official Oracle examination that awards the Oracle Database 19c Certified Professional (RAC, ASM, and Grid Infrastructure Administration) certification to candidates who pass it. Within the Oracle program it is classed as a Professional credential. It sits alongside related certifications such as Oracle Database 19c Administrator Certified Professional. Because the credential comes straight from the vendor, employers treat it as verified proof of skill — and the 79 practice questions at Lead2PassExam follow the same published blueprint.
Registration for the 1z1-078 exam runs through the official channels below:
Depending on availability in your region, the 1z1-078 exam is taken Online proctored or test center (Pearson VUE).
Our money-back guarantee applies if you sit the corresponding 1z1-078 exam within 60 days of purchase and do not pass: submit a scan of your enrollment slip plus the official Score Report PDF within 2 days of the exam, and the claim is settled within 7 days. The registration name must match the buyer's name; attempts within 3 days of purchase, downloads never used in a real sitting, free materials, and expired orders fall outside the policy. If you prefer, you can forgo the refund and instead receive two free exam products of equal value while keeping updates on your original purchase.

The official Oracle Database 19c: RAC, ASM, and Grid Infrastructure Administration blueprint breaks the content into 4 domains, starting with these three:
- High Availability and Troubleshooting
- Automatic Storage Management (ASM)
- Oracle Grid Infrastructure
The full domain-by-domain outline is listed above on this page — use it as your checklist while you work through the Lead2PassExam practice questions.
On exam day you will have 120 minutes to complete 60-70 (varies; Oracle does not always publish exact count) questions in the 1z1-078 exam. Divide your attention deliberately: answer what you know first, mark anything doubtful, and sweep back through flagged items near the end rather than burning minutes on a single question. The best way to defuse time pressure is exposure — schedule at least one full-length timed session in the Lead2PassExam test engine so the pacing feels automatic when it counts.
For structured learning, Oracle recommends these official courses for 1z1-078 candidates:
Courses explain the why; the 79 practice questions at Lead2PassExam drill the how-fast. Combining the two is the shortest route most candidates find.
Before you register, review the stated prerequisites: Recommended: Oracle Database 19c Administrator Certified Professional (1Z0-082) or equivalent knowledge
