This course contains the use of artificial intelligence.
Knowing a SQL rule is only part of preparation for Oracle Database Administration I. You also need to predict what a query returns, identify the configuration layer behind an error, and choose an administrative action that fits the stated constraints.
Build that judgment with 360 original practice questions in six tests. Each question includes an explanation for every option, an overall reasoning explanation, and a study tip. The content follows the published 1Z0-082 topic scope and uses Oracle Database 19c as its technical baseline.
Start with four focused practice sets
The focused sets use an author-selected 90-minute limit and 80% review target. Use them to find and explain mistakes before moving to timed practice.
Then attempt two full-length mock exams
Each mock contains 72 questions across the 23 published topic groups, with a 120-minute limit and 60% practice passing threshold matching the published exam format checked in October 2026. The topic distribution and difficulty are designed for this course; they do not reproduce undisclosed official weighting or predict an official scaled result.
The mocks change decision conditions: a configured growth limit can differ from physical capacity; a scalar aggregate can return zero or no row; a null-handling function can change an average's denominator; a deferred constraint can affect the whole transaction. Work through the given conditions rather than relying on familiar answer wording.
Turn mistakes into a review plan
This is a practice-test course, not a video course or a supplied database lab. Command and query examples are instructional; use an authorized practice environment for hands-on work.
Certification boundary: this course prepares for Administration I, 1Z0-082. Administration II and the separate 1Z0-182 exam are outside this course. Administration I is one part of the Database Administration 2019 certification pathway; the pathway badge on the cover does not mean this course awards that certification.
These are original practice questions, not official or recalled exam questions. BrightRung Learning is independent of Oracle. No endorsement, certification award, or exam-pass guarantee is implied.
