1Z1-921 Exam FAQ: Answers to Read Before You Book

The Oracle MySQL 2021 Implementation Essentials is the official Oracle exam that leads to the Oracle MySQL 2021 Certified Implementation Specialist certification at the Specialist 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 MySQL Certified Professional, so it can serve as a solid step in a broader certification path.

The 1Z1-921 exam has 52-78 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 PracticeMaterial desktop or online test engine under the same 90 minutes limit, and repeat until you can finish with a few minutes left for review.

The passing score for the 1Z1-921 exam is 65%, and the official registration fee is USD $245. 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.

Question #3

An existing MySQL Database environment has been doing backup and restore in a logical way by using the mysq1dump and mysq1 client utilities. When the backup is started using mysqldump with single-transaction mode, the existing application has long wait time. When the restore is required, it takes more than three hours to restore.
What two are benefits of using mysqlbackup from MySQL Enterprise Backup in this situation?

  • A. MySQL Enterprise Backup provides tape backup integration by default. It has the virtual tape option, which allows backup to tape device directly without extra third-party software integration.
  • B. MySQL Enterprise Backup does not back up system data so that it is much faster.
  • C. mysqlbackup utilities dump the full database into a SQL file, which is imported into the mysql client in single-thread mode. mysqlbackup restores data from physical backups. Physical backup methods are faster than logical methods because they involve only file coping without conversion.
  • D. mysqlbackup from MySQL Enterprise Backup allows logical backup with concurrency built in to get faster backup speed and restoration speed.
  • E. mysqlbackup can back up tables with the InnoDB engine without blocking. The backup is hot with InnoDB. Together with Incremental Backup, mysqlbackup from MySQL Enterprise Backup shortens the backup windows.
