Oracle Database Administration II 1Z0-083 Practice Tests

This course contains the use of artificial intelligence.

Knowing an RMAN command is only part of the job. Can you choose a usable recovery chain, preserve a sibling PDB's valid work, distinguish a failed SQL patch from a successful home patch, or explain why a tuning recommendation made production slower? These practice tests turn Oracle Database Administration II topics into decisions you can explain.

336 original English questions across six tests combine focused practice with mixed timed assessment. Every question includes the correct answer, feedback for every option, an overall explanation and a focused study tip. Single-answer and multiple-answer questions make you examine both the required action and the plausible mistake.

Start with the four focused tests

• Multitenant administration: 50 questions on CDB/PDB structure, services and lifecycle, cloning, application containers, security and Resource Manager.
• RMAN backup design and maintenance: 50 questions on backup formats, incremental chains, catalogs, channels, encryption, retention, archived logs and backup performance.
• Recovery, duplication and transport: 50 questions on crash and media failures, complete and point-in-time recovery, flashback, corruption, duplication and cross-platform transport.
• Deployment and performance decisions: 50 questions on installation, DBCA, upgrades, patching, Oracle Restart, 19c enhancements, performance evidence, memory, optimizer statistics and advisors.

Each focused test allows 90 minutes and uses an author-set 80% review target. Use these tests to find a gap and understand the decision before increasing speed.

Then test transfer with two mixed mocks

Each mock contains 68 questions in 120 minutes, using a 57% review threshold that matches the published exam figures checked on October 11, 2026. The topic mix and proportions of question types are author-designed; a practice score is not a prediction of an official result.

The mocks introduce further evidence and constraints: a readable backup without enough redo, an available catalog with the wrong channel device, a saved PDB mode that differs from the intended startup mode, and application validation that fails after a technically completed upgrade. Work through what the facts establish instead of choosing a familiar keyword.

Use the feedback to close the gap

1. Attempt a focused test before reading its explanations.
2. For each missed question, identify the condition you overlooked: container, endpoint, historical source, resource limit or execution stage.
3. Follow the study tip and revisit the relevant Oracle 19c documentation or your permitted lab.
4. Take a mixed mock under its time limit, then review both wrong answers and uncertain guesses.

The explanations separate metadata from backup payload, restore from recovery, relative shares from hard limits, and optimizer estimates from measured execution. They help you recognize why a tempting alternative fails in the stated scenario.

This course targets Oracle Database Administration II, exam 1Z0-083, within the Oracle Database Administration 2019 Certified Professional path, using the published topic outline and Oracle 19c technical behavior. The certification path involves additional requirements beyond this one exam. Check Oracle's official exam and certification information before booking, since availability, format and requirements can change.

This is independent exam preparation containing original practice questions. It is not an Oracle course, endorsement, or collection of actual exam questions. It is a practice-test course; it does not include video lectures, a managed lab, or an official certification voucher.
