問題 #2
You recently upgraded your Exadata image to the latest release; previously you were using 11.2.0.3.
At the same time, you decide to address some perfiormance problems as fiollows:

cells.
You have complaints ofi erratic perfiormance firom certain write-intensive applications.
Which two actions could improve perfiormance in these areas?
A. Configure Smart Flash Log on the database server to use server flash memory.
B. Configure Smart Flash Log on the cells to use some ofi these ofi the space on the cell flash devices.
C. Configure the table belonging to the affected application using CELLCLI, to the set CELL_FLASH_CACHE = KEEP.
D. Enable write-back flashcache by setting lunWriteCacheMode to Write Back Mode.
E. Use ALTER TABLE in the database to set CELL_FLASH_CACHE = KEEP fior the tables belonging to the affected
application.
問題 #3

ASM diskgroup. Identifiy three statements that correctly explain where the compression and decompression can be
done.
A. Decompression can be done on the database servers.
B. Decompression can be done on the Exadata storage servers.
C. Compression can be done on the database servers.
D. Compression can be done on the Exadata storage servers.
問題 #4
You are about to replace one memory DIMM in an Exadata storage server and need to power off the affected cell.
Which fiour commands must you execute to safiely power off the storage server in your standard deployed quarter rack
Database Machine assuming that redundancy is not compromised?
A. CellCLI> LIST GRIDDISK WHERE STATUS != 'inactive'
B. CellCLI> LIST GRIDDISK ATTRIBUTE name WHERE asmdeactivationoutcome != 'Yes'
C. 'crsctl stop cluster -all' on one ofi the database servers
D. CellCLI> ALTER GRIDDISK ALL INACTIVE
E. 'shutdown -h now' on the affected cell
問題 #5
Your database Machine has the exachk utility pre-installed and you decide to use it periodically, to validate the
installation against Oracle's recommended best practices.
Which two actions could you take to do this?
A. Run it once on each cell and it will then perfiorm periodic monitoring automatically.
B. Use a cron job on a database node to run it at regular intervals.
C. Create a Job in Enterprise Manager to run the exachk utility at regular intervals.
D. Use a cron job on each cell to run it at regular intervals.
E. Rut it once firom a database node and it will then perfiorm periodic monitoring automatically.
