The Oracle Enterprise Manager Grid Control Exadata Monitoring plug-in bundle allows you to monitor the following key components of Exadata machine:
* Oracle ILOM: The plug-in monitors the Oracle ILOM card in a database server for hardware events and records sensor data.
* InifiniBand Switch: The plug-in enables Enterprise Manager Grid Control to monitor the Oracle DataCenter36 Infiniband Switch.
* Avocent MergePoint Unity Switch: The Plug-in enables Enterprise Manager Grid Control to monitor KVM (keyboard, video or visual display unit, mouse) targets. The plug-in provides status of the KVM and the event occurrences like Factory Defaults Set, Fan Failure, Aggregated TargetDevice Status, Power Supply Failure, Power Supply Restored, Reboot Started, Temperature Out of Range on the KVM target.
* Cisco Switch: The plug-in enables Enterprise Manager Grid Control to monitor Cisco Switch targets. This plug-in will monitor the Cisco switch's CPU, memory, temperature, network interfaces, system information, fan, and power supply metrics.
* Power Distribution Unit: The plug-in will be used to monitor PDU's actual current value of Phase1, Phase2, and Phase3 References: http://www.oracle.com/technetwork/oem/grid-control/exadata-plug-in-bundle-188771.html

B: In order for queries to take advantage of Exadata's Offloading capabilities, the optimizer must decide to execute a statement with a Full Table Scan or a Fast Full Index Scan.
F: Smart Scans can be used for full scanning through B*Tree index segments.

Explanation/Reference:
The fastest database backup is achieved via InfiniBand.
Get dedicated Media Servers that connect to tape library

Offers backup rates of up to 12GB/sec

RMAN does not back up directly to tape. However, it will integrate with media management software such as Oracle Secure Backup and utilize their capabilities to manage tape libraries.
Exadata Database Machine: The Database Machine contains the databases that need to be backed up.
Oracle RMAN is the only mechanism to back up the databases that utilize Exadata Storage Servers as the storage. RMAN processes run on the database servers and interact with the Oracle Secure Backup (OSB) agent, which further interacts with the media management software and enables RMAN to communicate with the tape library.

D: With Exadata storage, database operations are handled much more efficiently. Queries that perform table scans can be processed within Exadata storage with only the required subset of data returned to the database server. Row filtering, column filtering and some join processing (among other functions) are performed within the Exadata storage cells. When this takes place only the relevant and required data is returned to the database server.
E: With Smart Scan processing, row filtering, column filtering, some join processing, and other functions are performed in the Exadata cells.
