In which scenario will griddisks residing on the same celldisk have balanced performance characteristics in an X5 High Capacity Exadata Storage Server?

• A.griddisks on memory based celldisks
• B.griddisks on Flash-based celldisks
• C.griddisks on hard disk-based celldisk consumed by ASM when creating diskgroups using ASM-based Intelligent Data Placement (IDP)
• D.griddisks on hard disk-based celldisks consumed by the Database Smart Flash Cache

Which three statements are true about the CELLCLI command?

• A.It has command-line history.
• B.It can be executed using the DCLI utility.
• C.It can be executed on storage servers.
• D.It requires root privileges to create CELLDISKS and GRIDDISKS.
• E.It can execute commands on multiple storage servers in parallel.

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

• A.Block Change Tracking (BCT) is not needed for databases in an X5 Database Machine, because change tracking is done by cellsrv.
• B.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.
• C.cellsrv filters blocks and returns only those that have changed since the last backup, for databases in noarchivelogmode.
• D.cellsrv filters blocks and returns only those that have changed since the last backup, for databases in archivelogmode.
• E.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.

Which two statements are true about the EXACLI utility?

• A.It requires the same privileges as the celladmin linux user to create CELLDISKS and GRIDDISKS.
• B.It can be executed using the EXADCLI utility.
• C.It supports all CELLCLI commands.
• D.It can be executed directly on cells.
• E.It requires access through a cell user that has role-based privileges granted.
• F.It can execute commands on multiple cells in parallel.

Examine this IORM plan:

Which two are true concerning this plan?

• A.If I/Os come from the HR database only, then they may get up to 10% of the I/O bandwidth on the cell.
• B.The Finance database can use at least 45%, but never more than 60%, of the total Flash Cache capacity.
• C.I/Os from the finance database are guaranteed to get 45% of the I/O bandwidth if the demand is at least 60% of the maximum I/O rate of the cell, but may get 100% of the I/O bandwidth if no other databases are performing I/O to the cell.
• D.If I/Os come from the HR database only, then they may get up to 100% of the I/O bandwidth on the cell.
• E.I/Os from the finance database are guaranteed to get a minimum of 45% of the I/O bandwidth if the demand exists, and a maximum of 60% of the I/O bandwidth even if no other databases are doing I/O to the cell, and the demand from the finance database exceeds 60% of the maximum I/O rate of the cell.
