B. Column projection does not contribute to the performance benefit of Smart Scan
C. It is possible to offload single row functions to the storage servers.
D. Some joins can be offloaded to the storage servers.
E. A query rewrite may occur to a container table stored Exadata, and it will always benefit from Smart Scan.
F. All joins can be offloaded to the storage servers.
Q2. Which two are true about the use of DBFS in a Database Machine environment?
A. DBFS must be used to bulk load data into a database on the Database Machine if the staging area requires Exadata based shared storage.
B. DBFS must be used to have a POSIX compliant shared storage solution that is accessible from the database servers on a Database Machine.
C. DBFS must be used to bulk load data into a production database on the Database Machine.
D. DBFSmust use the DBFS_DG diskgroup for any DBFS store.
E. DBFS must be used to have a POSIX-compliant Exadata-based shared storage solution.
Q3. Identify the three components that serve a purpose only in the Database Machine.
A. ASM intelligent Data Placement (IDP)
B. Intelligent Database Protocol (IDB)
C. Database Resource Manager (DBRM)
D. I/O Resource Manager (IORM)
E. Database Filesystem (DBFS)
F. The DISKMON process
Q4. 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
Q5. You plan to monitor the status of the motherboard, memory, power, fans, and network cards on the database nodes in your Database machine using Enterprise Manager.
Where must you set the thresholds for these hardware components and why to assure that sensor readings, faults any related alerts, are visible in Enterprise Manager?
A. Set thresholds in ILOM and in Enterprise Manager because they are not preset anywhere and must be set in both places
B. Set thresholds only in ILOM because they are not preset anywhere but need only be set in ILOM.
C. No thresholds need be set because they are preset in the ILOM and in Enterprise Manager.
D. No thresholds needho set because they are preset in the ILOM and these are sufficient for monitoring.

Q6. Which two are regarding the case of storage indexes?
A. To increase the chance of using the a storage index, you can make table indexes invisible.
B. To maximize the benefit of storage Indexes, load your data stored on the filtered columns.
C. The cell physical 10 bytes saved by storage index statistic returns multiple rows, one for each storage server.
D. Storage indexes are retained after a cell is rebooted.
E. Avoid the use of bind variables because Storage Indexes do not work with bind variables.
Q7. 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,whichselect 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.
Q8. Which two are true about the use of the Integrated Lights Out Manager (ILOM) on the Database Machine?
A. ILOM can be used to power-on the Cisco switch.
B. ILOM can be used to power on the InfiniBand switches.
C. ILOM can be used to power-on the database servers.
D. ILOM generates hardware alerts for the power distribution units.
E. ILOM provides a remote console for the storage servers.
