                                                          Frequently Asked Questions About Oracle Database Administration II

                                                          The Oracle Database Administration II exam (exam code 1Z0-083) is the official Oracle exam that leads to the Oracle Database Administration 2019 Certified Professional certification, sitting at the Professional level of the Oracle certification track. It is also connected with Oracle Database Administration 2019 Certified Professional (Upgrade), ORACLE MASTER Gold DBA 2019. If this is the credential you are working toward, the 283 practice questions at Actual4Cert map directly to its objectives.

                                                          The Oracle Database Administration II exam includes 68 questions, and you have 120 minutes to complete them. Divide the time limit by the question count and you get a tight average pace per item, so train yourself to flag time-consuming questions and return to them later instead of getting stuck. Before test day, run at least one full timed session in the Actual4Cert test engine under the same limits — the clock should never surprise you.

                                                          The passing score for Oracle Database Administration II is 57%, and the official registration fee is USD 245. A failed attempt means paying that fee in full again, so your preparation budget deserves the same attention as your study plan. A practical rule: book your exam date only after you can finish a Actual4Cert practice test comfortably above the passing score more than once.

                                                          According to Oracle, candidates should meet the following before registering: Oracle Database Administration I (1Z0-082) certification or equivalent knowledge; hands-on experience with Oracle Database 19c recommended. Requirements can change, so confirm the latest details on the official exam page before you register.

                                                          You can register for the Oracle Database Administration II exam through the official channels below:
