A. Advanced Compression is good for tables with active updates and deletes, whereas Hybrid Columnar Compression is best applied to tables or partitions where data is fairly static.

B. Advanced Compression is free to use on Exadata Database Machine, whereas Hybrid Columnar Compression must be purchased.

C. They are the same; Advanced Compression is called Hybrid Columnar Compression on Exadata Database Machine.

D. Hybrid Columnar Compression is good for tables with active updates and deletes, and provides deeper compression ratios.

A. ASR Manager inside the firewall to ensure that root access to Exadata Database Machine is not compromised

B. Enterprise Manager, SQL Developer Server, and ASR Manager on the stand-alone server because ASR needs SQL Developer to gain SQL access to the database server

C. Enterprise Manager (Ops Center) and ASR Manager on the stand-alone server because ASR is not a monitoring tool

D. ASR Manager with SNMP traps configured to listen for specific alerts triggered by Exadata Database Machine

A. flashcachemode should be set to write back by updating cellinit.ora and restarting cellsrv.

B. Write back flash cache requires a minimum required software version.

C. Before write-back-flash-cache is enabled you need to drop the flash cache first.

D. When enabling write-back-flash-cache in a non-rolling manners it is important to ensure that asmdeactivationoutcome is set to yes andasmmodestatus is set to online for all grid disks.

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

A. The storage index data is not on the Cell Server's region index memory structures yet because this predicate has not been used.

B. The storage indexes were disabled by using the DISABLE_STORAGE_INDEX parameter.

C. The accumulated I/O saved by the storage index is 1.68 MB.

D. Since the database was started, no queries were run against this table with the same predicate.

E. The storage indexes reduced the amount of physical I/O bytes significantly for this query.

A. predicate filtering

B. column projection

C. sharding

D. Smart Scan

E. offloading

A. Fields in AlertHistory cannot be modified.

B. Metric values are computed and stored in memory, and then permanently stored on disk.

C. DBMCLI can be used to report on Exadata storage server metrics.

D. DBMCLI reported metrics are informational only and cannot be used to trigger alerts or reported events.

E. Metrics are reported as one of four types: cumulative, instantaneous, rate, or transition.

A. A non-partitioned table can use Advanced Compression and Hybrid Columnar Compression concurrently.

B. A partitioned table can define the use of Advanced Compression Hybrid Columnar Compression for each partition.

C. A partitioned table can use only Advanced Compression or only Hybrid Columnar Compression.

D. Hybrid Columnar Compression can be defined for a single column.

A. operating system components

B. software assets

C. data entry errors

D. backup and restore failures

E. hardware assets

A. storage server rebalancing

B. installation or reconfiguration of significant non-Oracle software

C. before shutdown to preserve storage indexes

D. addition of an Exadata storage expansion rack

E. application of Oracle patches

F. reconfiguration of significant operating system parameters

G. application of operating system patches
