A. A customer can associate an SR to their configuration data to reduce issue resolution time.

B. Configuration collection occurs every 24 hours.

C. Oracle Base, ASM, and GRID home must have the same owner for installation to work.

D. It is used to collect configuration details and upload them to the management repository.

E. Configuration collection happens once an hour.

A. When enabling write-back flash cache in a non-rolling manner, it is important to ensure that asmdeactivationoutcome is set to YES and asmModeStatus is set to ONLINE for all grid disks.

B. The setting flashCacheMode should be set to Writeback by updating cellkey.ora and restarting cellsrv.

C. When enabling write-back flash cache in a rolling manner, DBCLI should be used to inactivate the grid disks on all cells first.

D. Before write-back flash cache is enabled, you need to drop the Flash Cache first.

E. Write-back flash cache requires a minimum required software version.

A. upgrades one or more Exadata Storage Servers and InfiniBand Switches

B. upgrades an Exadata Storage Server named dm01

C. upgrades one or more Exadata Storage Servers, one at a time

D. upgrades one or more Exadata Storage Servers simultaneously

E. upgrades one or more Exadata Storage Servers listed in the dm01 file

F. rolls back one or more Exadata Storage Servers to the previous release

A. indexes that rely on B-Tree pointers

B. incremental backups with block change tracking

C. joins and aggregation

D. table scans

E. column filtering

A. only 1 and 2

B. none

C. only 2

D. only 3

E. only 2 and 3

F. 1, 2, 3, and 4

A. Normal redundancy (best practice) provides protection against two simultaneous disk failures, whereas High redundancy provides protection against a single disk failure or an entire storage server failure.

B. Normal redundancy protects from disk failure when a cell is offline or being updated, whereas High redundancy protects the system when all the cells are offline.

C. Normal redundancy protects the DATA diskgroup, whereas High redundancy protects the RECO diskgroup.

D. Normal redundancy tolerates a single cell failure, whereas High redundancy tolerates a two-cell failure.

E. High redundancy gives more usable storage, whereas Normal redundancy provides better I/O performance.

A. setting the initialization parameter PARALLEL_ENABLED to TRUE to enable parallel direct path loads

B. adding the PARALLEL hint to the CTAS or IAS statement

C. creating the required environment by using Smart Scan parallelization

D. setting the PARALLEL_FORCE_LOCAL parameter to TRUE

E. setting the PARALLEL clause on both the external table and the table where you are loading the data

A. All indexes should be dropped when migrating to Exadata.

B. The logical migration methods allow more flexibility in changing the database structure for best performance than the physical methods.

C. Because Exadata uses InfiniBand, in order to migrate your database to Exadata, you must have InfiniBand on the system that you are migrating from.

D. Using Data Guard Physical Standby to migrate from an 11.1 database to Exadata is beneficial because it allows you to adopt HCC during migration.

E. ASM and the database best practice configuration that is supplied during Exadata deployment should be retained during and after migration.

A. Provide individual x86 64-Bit gateway hardware.

B. Install on Oracle Database Appliance.

C. Purchase the recommended x86 64-Bit gateway hardware from Oracle.

D. Install in Oracle Virtual Machine with required hardware.

E. Install on Exadata Engineered System.
