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