A. Set up Oracle Grid Infrastructure to use multiple clusters per hardware pool.

B. Use IORM to distribute disk bandwidth among the databases.

C. Use ASM to create separate diskgroups for each database instance that is running on Exadata.

D. Set up a resource consumer group within each database instance and manage it individually.

E. Do not use IORM because it will interfere with the shared database functionality on Exadata.

A. The cell software backup is performed through CellCLI and cell recovery is accomplished by using a rescue procedure.

B. The cell software backup is automatic and cell recovery is accomplished by using a rescue procedure.

C. The database server software backup is automatic and recovery is accomplished by using a rescue procedure.

D. The data that is stored in a database is backed up and restored by using CellCLI commands.

E. The data that is stored in a database is backed up and restored by using RMAN commands.

A. In an Exadata storage server, 12 DATA grid disks, 12 RECO grid disks, and 12 DBFS_DG grid disks are configured by default.

B. The redundancy setting can be changed easily if a wrong choice is made between Normal and High.

C. If High redundancy is selected, grid disks from at least two storage servers must be specified.

D. The disks in ASM diskgroups must have similar performance characteristics in addition to having the same size.

E. HP and HC disks can be mixed to any capacity within the same diskgroup.

A. upgrades one or more Exadata Storage Servers simultaneously

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

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

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

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

F. upgrades an Exadata Storage Server named dm01

A. adds a dialog box that prompts for a backup before the patch can be applied

B. creates a backup of the Oracle database data files

C. forces the software to create a backup of the exadbpatch.cfg file

D. creates a backup of the patch in case of an error in the patching routine

E. performs a backup of each Oracle home directory before a patch is applied

A. prioritization of disk I/Os based on the database

B. grid disks with default AU allocation sizes of 1 MB

C. database storage flash cache space allocation guarantees and limits

D. usage of flash technology to cache recently used data

E. prioritization of OLTP I/Os over scan I/Os

A. Configuration collection happens once an hour.

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

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. DBFS allow customer to store LOB and CLOB files external to database for more flexibility.

B. Tens of thousands of files are the perfect use case for DBFS on Exadata.

C. DBFS offers tremendous I/O bandwidth.

D. When using DBFS customers will not need to use FUSE or any client software to administer the file system.

E. DBFS in an Exadata environment is faster than an NFS mount system because of smart scan performance gain.
