                                                  1Z0-908 Exam FAQ: Answers to Read Before You Book

                                                  The Oracle MySQL 8.0 Database Administrator is the official Oracle exam that leads to the Oracle Certified Professional, MySQL Database Administrator (OCP MySQL DBA) certification at the Professional level. Passing it validates your skills against Oracle standards and proves your qualification to current and future employers. The credential is also connected with related certifications such as Oracle Certified Associate, MySQL 8.0 Database Administrator, Oracle MySQL HeatWave certifications, so it can serve as a solid step in a broader certification path.

                                                  The 1Z0-908 exam has 50-60 questions in total and must be completed within 90 minutes. That leaves only a narrow time budget per item, so train yourself to flag a difficult question, move on, and circle back later instead of getting stuck. A week or two before your test date, run at least one full timed mock exam in the Actual4Dumps desktop or online test engine under the same 90 minutes limit, and repeat until you can finish with a few minutes left for review.

Keep in mind that a failed attempt is not discounted — retaking the exam means paying the full fee again — so it is wise not to book your seat until your practice scores sit comfortably above the passing mark. Working through the 142 questions at Actual4Dumps in timed mode is a reliable way to judge when you are truly ready.

                                                  Question #1

                                                  Examine this output:

                                                  You plan to add this parameter to the configuration: innodb_directories='/innodb_extras' Which statement is true?

                                                  • A. It moves all innodb tablespaces to the /innodb_extras directory to enable a new innodb_data_home_dir to be defined.
                                                  • B. It is not necessary because innodb_data_home_dir is already defined.
                                                  • C. It defines all innodb tablespace options relative to a starting parent directory.
                                                  • D. It allows scanning of other locations to discover more innodb tablespaces.
                                                  • E. It adds more temporary workspace in addition to the innodb_tmpdir location.

                                                  • C. Group Replication is still operational, but InnoDB Cluster must be reimported under MySQL Shell.

                                                  You have restored the last backup, which corresponds to the start of the binlog.000036 binary log.
