Your Oracle Database Administration I Exam Questions, Resolved
The Oracle Database Administration I exam is split across 16 areas, with Restricting and Sorting Data, Using the Set Operators, Using Conversion Functions and Conditional Expressions carrying the most weight. Study in proportion to those shares — the full outline is in the section above this page.
The Oracle Database Administration I exam costs $245 USD per attempt, with 64% required to pass. Fail, and that fee returns in full for the retake. Practice with Actual4Cert questions until your timed mock scores clear 64% comfortably — then the exam fee is a single payment, not a subscription.
The 1Z0-082 exam is Oracle's official certification test — passing it earns the Oracle Database 19c credential at the Associate level. Its influence comes from how practical it is: employers use the Oracle Database Administration I certificate as proof that you can do the work, not just talk about it. It also connects to Oracle Certified Associate (OCA) - Oracle Database Administration 2019, giving the credential a natural next step.
