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

Which two statements are true about MySQL Enterprise Firewall?
A. On Windows systems, MySQL Enterprise Firewall is controlled and managed by using the Windows Internet Connection Firewall control panel.

C. MySQL Enterprise Firewall is available only in MySQL Enterprise versions 5.7.10.and later.
D. Server-side plug-ins named MYSQL_FIREWALL_USERS and MYSQL_FIREWALL-WHITELIST implement INFORMATION_SCHEMA tables that provide views into the firewall data cache.

By using the asynchronous MySQL Replication architecture, data can be replicated to slaves. Identify three use cases of MySQL Replication.
A. MySQL Replication Connector/J (ReplicationDriver) is provided to allow read capability on slave and write capability on master.
B. MySQL Enterprise Backup will back up from Slave automatically.
C. It provides multi-master access where the application can write and read data across the database servers.
D. It allows backup to be done on the slave without impacting the master.
E. You can create a slave server for reporting applications, which get only read access to the slave servers. It off-loads the master server. Additional servers allow different database server configuration.
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. 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.
C. 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.
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. mysqlbackup from MySQL Enterprise Backup allows logical backup with concurrency built in to get faster backup speed and restoration speed.
MySQL is installed on a Linux server with the configuration:
Which two methods can change the default options to use the authentication plug-in that implements SHA-256 hashing for user account passwords?

C. Add default_authentication_plugin=sha256_password under [mysqld] in the configuration file.
D. Create user by using CREATE USER ‘newuser’@’localhost’ IDENTIFIED WITH ‘Sh@256Pa33’;
