NEW QUESTION 42
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?

MySQL Enterprise Backup does not back up system data so that it is much faster.

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.

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.

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.

mysqlbackup from MySQL Enterprise Backup allows logical backup with concurrency built in to get faster backup speed and restoration speed.

You want to create an encrypted table. So, you enter this command:
CREATE TABLE ‘test_encryption2% (
‘id’ int(10) unsigned NOT NULL AUTO_INCREMENT,
‘server_name’ varchar(15) NOT NULL,
PRIMARY KEY (‘id’) ) ENGINE=MYISAM AUTO_INCREMENT=l DEFAULT CHARSET=latin1 ENCRYPTION = ‘Y1; You receive the following error:
ERROR 1031 (HY000): Table storage engine for ‘test_encryption2’ doesn’t have this option Which statement correctly explains the reason for this error?

You cannot use the AUTO_INCREMENT option to create an encrypted table. This is what is causing the error.

The term “server_name” is a reserved MySQL term. You cannot use it for the new table. This is what is causing the error.

The encryption feature only works with InnoDB tables. You are creating a MylSAM table, and it is causing the error.

The test_encryption2 already exist. You are not using the correct option to recreate it and it is causing the error.
