Oracle MySQL 2021 Implementation Essentials Sample Questions:

1. 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) mysqlbackup from MySQL Enterprise Backup allows logical backup with concurrency built in to get faster backup speed and restoration speed.
B) 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.
C) MySQL Enterprise Backup does not back up system data so that it is much faster.
D) 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.
E) 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.

ERROR 1031 (HY000): Table storage engine for 'test_encryption2' doesn't have this option Which statement correctly explains the reason for this error?

A) The encryption feature only works with InnoDB tables. You are creating a MylSAM table, and it is causing the error.
B) You cannot use the AUTO_INCREMENT option to create an encrypted table. This is what is causing the error.
C) The test_encryption2 already exist. You are not using the correct option to recreate it and it is causing the error.
