Question 21 🔥

Which two statements are true about RMAN incremental level-1 backups for a database running on an X5 Database Machine?

Which database solution meets these requirements?

A. Block Change tracking (BCT) is not needed for databases in an X5 Database Machine, because ASM automatically does block change tracking when diskgroups are built from griddisks.

Highly voted

B. cellsrv filters blocks and returns only those that have changed since the last backup, for databases in archivelog mode.

Highly voted

C. cellsrv returns all blocks that have been or might have been changed since the last backup, and RMAN filters the blocks that do not require backup.

Highly voted

D. cellsrv filters blocks and returns only those that have changed since the last backup, for databases in noarchivelog mode.

Highly voted

E. Block Change Tracking (BCT) is not needed for databases in an X5 Database Machine, because change tracking is done by cellsrv.

Question 24 🔥

Batch and DSS workloads on your Exadata X6 Database Machine are causing performance problems for OLTP workloads at certain times of the day.There are five RAC databases performing OLTP I/O. Two of them also perform batch I/O. There is another RAC database that performs only DSS I/O.You are asked to resolve this problem so that the OLTP workload will not suffer when competing with the batch or DSS workloads.You decide to use the I/O resource manager.Which is the best way to solve this problem?

Which database solution meets these requirements?

A. Create a category plan with EXADCLI calling EXACLI to give the OLTP category the highest priority on all the cells, and use the Database Resource Manager to create the OLTP category and map all OLTP- oriented consumer groups in all databases to it.

Highly voted

B. Use the Database Resource Manager to give the OLTP category the highest priority and use EXADCLI calling EXACLI to create the OLTP category on all the cells.

Highly voted

C. Create a category plan with EXADCLI calling EXACLI to give the OLTP category the highest priority on all the cells, and use the Database Resource Manager to give the OLTP consumer group the highest priority on all databases.

Highly voted

D. Create a database plan using EXADCLI calling EXACLI to give OLTP I/O the highest priority from all six databases.
