Question 6

A customer has three databases named CC. FIN, and DW. The CC database is for their CallCenter. Even a slight decrease in the response time of the database would mean more people "on hold" in their data center. The orders received through the CallCenter are stored in the Finance (FIN) database. Both databases, CC and FIN, serve as sources for the Data Warehouse (DW) database. All databases use the same Automatic Storage Management (ASM) diskgroup and therefore, the same physical disks on Exadata storage. The customer wants to dynamically control the resources that are available for the CallCenter database because this has direct impact on their operations?
Which option should be implemented?

A. DBRMon the CC database B. IORM and DBRM C. DBRM on all the databases D. IORM, because DBRM cannot be changed for an existing session
