                                                          Everything Candidates Ask About Oracle Database Administration II

                                                          The 1Z1-083 exam, officially titled Oracle Database Administration II, is the qualifying exam for the Oracle Database Administration 2019 Certified Professional certification, which sits at the Professional level. Earning it shows employers that you have the skills the credential stands for, and it is a solid step forward on a Oracle career path. It also connects to Oracle Database Administration 2019 Certified Professional (Upgrade), ORACLE MASTER Gold DBA 2019, so the effort you put in now keeps paying off as you advance.

                                                          The 1Z1-083 exam gives you 68 questions to complete within 120 minutes. Do the math before exam day: divide the total time by the question count to set a steady per-question pace, and flag any item that stalls you so you can return to it after securing the easier points. The most reliable way to build that rhythm is a full timed practice test under the same limit, which is exactly what TestSimulate's test engines are designed for.

                                                          The passing score for Oracle Database Administration II is 57%, and the official registration fee is USD 245. Keep in mind that a retake means paying that fee again in full, which makes an honest self-check worthwhile: before you book, sit a timed practice test and make sure you are consistently scoring above the passing line with some margin to spare.

                                                          According to the official requirements: Oracle Database Administration I (1Z0-082) certification or equivalent knowledge; hands-on experience with Oracle Database 19c recommended. Eligibility rules do change from time to time, so confirm the current details on the official exam page before you register.

                                                          Some SQL statements perform poorly due to excessive hard parse activity, thereby degrading performance.

                                                          3. USER1.EMPis a table in PDB1and USER2.DEPTis a table in PDB2.
                                                          CDB1user SYSexecutes these commands after connecting successfully to PDB2:

                                                          Which two are true? (Choose two.)

                                                          A. The inserts on USER1.EMP were committed when the session inserted a row into USER2.DEPT.
                                                          B. The inserts on USER1.EMP were committed when the session connected to PDB2.
                                                          C. The insert on USER2.DEPT is uncommitted.
                                                          D. The inserts on USER1.EMP were rolled back when the session connected to PDB2.
                                                          E. The insert on USER2.DEPT is a recursive autonomous transaction by the child session and is committed.
                                                          F. The inserts on USER1.EMP remain uncommitted when the session connected to PDB2.
                                                          G. The insert on USER2.DEPT fails because of the active transaction in the parent container.

                                                          D. RMAN can recover tables owned by the SYSTEM user.
                                                          E. RMAN always uses an auxiliary instance.
