To troubleshoot a possible hardware problem, you consider moving all disk drives from one Exadata storage server to a replacement chassis.
You must contain storage availability while performing task.
The Exadata storage server is an X3-8 Database Machine and storage grid is not partitioned.
Which two factors would prevent you from moving the disks from one Exadata storage server to another one?

A The existence of an external redundancy ASM diskgroup
B The existence of a normal redundancy ASM diskgroup
C The existence of an ASM diskgroup with the repair_time attribute set to 0.
D The existence of an ASM diskgroup with its compatible.asm attribute set to 10.2.0.0.0
E Offline or inactive celldisks in another Exadata server

What is the benefit of bonding the client access network configuration?

A Improved performance
B Improved reliability
C Both improved performance and reliability
D A Single Client Access Name (SCAN)
E Improved monitoring

To guarantee proper cooling, you plan to place perforated floor tiles near your Database Machine.
Where, in relation to the cabinet, should they be placed?

A On the left side, because the air flow is from left to right
B At the back, because the air flow is from back to front
C On the right side, because the air flow is from right to left.
D At the front, because the air flow is from front to back
E Underneath the cabinet, because the air flow is from bottom to top

Identify two valid reasons for creating multiple griddisks on a Single celldisk.

A To segregate storage into multiple pools with different performance characteristics
B To facilitate normal or high redundancy ASM diskgroups
C To enable disk mirroring for the system area
D To segregate storage into multiple pools that can be assigned to different databases
E To segregate storage into multiple pools that can be assigned to different resource consumer groups in the same database.

You plan to migrate an Oracle database that supports an online transaction processing (OLTP) workload to your Database Machine.
Following are details for the source database:

Database version: 10.2.0 -
Byte order: Big Endian HP-UX (64-bit)

Database size: 24 TB -
Storage: ASM with 1 MB allocation unit size
Which two are supported migration methods?

A Physical migration using ASM online Migration
B Physical migration using Transportable Database
C Logical migration using Oracle Streams
D Local migration using Oracle Streams
E Logical migration using logical standby

You have configured a multi-rack Database Machine with two X3-8 full racks all in a single cluster and storage grid.
Which two are true regarding the servers on which Enterprise manager agents must be deployed in order to monitor all components of the multi-rack Database
Machine?

A On only one database server in the first rack
B On all storage servers in all racks
C On at least two storage servers in the first rack
D On all database servers in the first rack
E On only one database server in second rack
F On all database servers in second rack

Which three storage components are available after the standard initial Database machine deployment?

A The DATA_<DBM_Name> ASM diskgroup
B The RECO_<DBM_Name> ASM diskgroup
C Mirrored system partitions on hard disk 0 and hard disk 1
D The DBFS_DG diskgroup with external redundancy
E Exadata Smart Flash Cache using all of the flashdisk space

Yesterday, an Exadata storage server flashdisk entered the poor performance state.
This flashdisk os used by flashcache and has a griddisk which is a member of a normal redundancy diskgroup.
Identify the six steps you must perform to replace flashdisk.

A Identify the griddisk located on the poorly performing flashdisk and drop it from the associated ASm diskgroup.
B Verify that the griddisk located on the poorly performing flashdisk has been successfully dropped from the associated ASM diskgroup.
C Drop the flashcache on all cell.
D Safely power off the cell containing the poorly-performing flashdisk.
E Replace the poorly performing flashdisk.
F Power up the cell containing the replaced flashdisk and activate all griddisks.

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 performance problems as follows:
You noticed increased latency for the database log writer, especially during the quarterly battery learn cycle on the cells.
You have complaints of erratic performance from certain write-intensive applications.
Which two actions could improve performance in these areas?

A Enable write-back flashcache by setting lunWriteCacheMode to Write Back Mode.
B Use ALTER TABLE in the database to set CELL_FLASH_CACHE = KEEP for the tables belonging to the affected application.
C Configure Smart Flash Log on the cells to use some of these of the space on the cell flash devices.
D Configure the table belonging to the affected application using CELLCLI, to the set CELL_FLASH_CACHE = KEEP.
E Configure Smart Flash Log on the database server to use server flash memory. BC

Which two statements are true about the use of direct path loads when selecting from external tables in a database on a Database Machine?

A INSERT INTO . . . SELECT FROM statements, executed serially, which select from external tables, require the APPEND hint to use direct path loading.
B CREATE TABLE . . . AS SELECT statements, which select from external tables, attempt to use in direct path loading automatically.
C CREATE TABLE . . . AS SELECT statements, which select from external tables, require the APPEND hint to use direct path loading.
D INSERT INTO . . . SELECT FROM statements, executed serially, which select from external tables, are unable to use direct path loading.

Your customer wants you to partition the database and storage grids in his X3-2 full rack, creating database clusters and two storage grids.
One cluster will be used for production and should consist of 6 databases servers and 11 cells from the first storage grid.
The other cluster will be used for test and development, and should consist of 2 database servers and 3 cells from the second storage grid.
The storage must be partitioned so that the cells are visible only to the appropriate database servers based on the description above.
What must be done to achieve this?

A Configure Exadata realms using Oracle ASM scoped security mode.
B Configure Exadata realms using Database scoped security mode.
C Edit the CELLIP.ORA file on each database server to contain IP addresses of cells in the storage grid associated with cluster to which that database server belongs.
D Edit the CELLINIT.ORA file on each database server to contain IP addresses of cells in the storage grid associated with the cluster to which that database server belongs.
E Edit the CELLIP.ORA file on each database server to contain IP addresses of database servers which are allowed access to specific cells in the same storage grid.
F Edit the CELLIP.ORA file on each cell to contain IP addresses of database servers in the database server grid that are associated with the storage grid to which that cell belongs.

Which three statements are true about the initial storage configuration after the standard deployment of a new database Machine?

A The Data_<DBM_Name> and RECO_<DBM_Name> ASM diskgroups are built on part of the interleaved griddisks.
B The Data_<DBM_Name> and RECO_<DBM_Name> ASM diskgroups are built on top of the non-interleaved griddisks.
C There is a free space available on the hard disks inside the database servers for possible extension of the /u01 file system.
D There is no free disk space available on the hard disk inside the database servers for possible extensions of the /u01 file system.
E There is free space available on the flashdisk inside the Exadata storage servers for possible use as flash-based griddisks.
F There is no free disk available on the flashdisk inside the Exadata storage servers for possible use as flash-based griddisks.
