最新的 Oracle MySQL 1Z0-921 免費考試真題:

1. You have a MySQL Server instance (running with Port# 3306) monitored by the Service Manager in MySQL Enterprise Monitor. You cloned the MySQL Database instance and configured it to be a replicated MySQL instance as Slave using Port# 3316 on the same machine as the Master Server. The replication configuration is working correctly. The Master and Slave Servers are running.
You are trying to add the newly created MySQL Slave instance to the Monitor. The Service Manager in MySQL Enterprise Monitor notifies you that the new instance is successfully added; however, it is not added correctly at the newly added configuration points to the old Master monitored items. The Monitor shows only one monitored MySQL instance for Master and Slave.
Which two are possible reasons for this problem?

A) The MASTER and SLAVE are grouped as one instance for monitoring.
B) The SLAVE and MASTER instances are started with the same configured value for the option - - monitor_server_uuid.
C) All the MySQL instances (Master and Slave) have the same server_uuid in <datadir>/auto.cnf.
D) The mysql.instance table on SLAVE is cloned with the same content as MASTER, which has the same server UUID.
E) The mysql.inventory table on SLAVE is cloned with the same content as MASTER, which has the same server UUID.

2. What is Kubernetes in the context of MySQL?
Response:

A) A cloud service provided by Oracle for MySQL databases.
B) A database management tool for MySQL.
C) An open-source container orchestration platform.
D) A database engine for MySQL.

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

4. What SQL keyword must be specified when creating a foreign key constraint?

A) a TRIGGER on the child table for cascading delete statements
B) a REFERENCES in the child table to the parent table
C) unique PRIMARY key values for both child and parent tables
D) the SET_FOREGIN variable in the my .cnf file
E) an index on the foreign key

5. The user -os-user'@"localhost" was created to monitor connections and shut down the server, and was granted these privileges:
