According to Oracle.com documents or resources, the three options that are available for database consolidation on Exadata are:

A. Multiple pluggable databases in one or more container databases on a Virtual Machine or Bare Metal cluster123.

C. A single database with one or more schema per application12.

E. Multiple Databases on a cluster12.

In an Exadata environment, the path of communication for SNMP traps involves:

Management Server (MS) Process to EM Agent: Alerts related to the storage server are generated by the MS process, which then forwards SNMP traps directly to the Enterprise Manager agent, allowing centralized monitoring and alert management​.

ILOM to EM Agent: The ILOM on each Exadata storage server can independently send SNMP traps to the EM agent, providing additional hardware-level monitoring and alerting capabilities .

These pathways ensure that alerts from both hardware and software layers reach Enterprise Manager efficiently, supporting proactive management and rapid response to system issues.

A. YOU query VSSYSTEM_EVENTS and filter for the event ‘cell physical IO interconnect bytes returned by smart scan’, associated to your table. This does not show how much data was filtered by Smart Scan, but only how much data was returned after Smart Scan12.

C. You query v$SYSTAT and filter for the statistic ‘cell smart table scan’, associated to your table. This does not show how much data was filtered by Smart Scan for a specific table, but only for all tables in a session12.

The correct sequence is:

Review the safety guidelines. This is important to ensure a safe and successful installation1.

Unpack Oracle Exadata Rack. This involves removing the packaging materials and inspecting the rack for damage or missing components1.

Place Exadata in its allocated space. This involves moving the rack to its final location and securing it with bolts and brackets1.

Let the Exadata acclimatize for 24 hours. This is recommended to allow the rack components to adjust to the ambient temperature and humidity before powering on1.

Stabilize the Exadata Rack. This involves leveling the rack and adjusting its height if needed1.

Power on Exadata PDU B. This involves connecting PDU B to a power source and turning it on1.

Power on Exadata PDU A. This involves connecting PDU A to a power source and turning it on1

The statements that are true about the CellCLI command are:

It has command-line history . According to 1, you can use the up and down arrow keys to scroll through previous commands that you entered in CellCLI . You can also use Ctrl+R to search for a previous command by entering part of it .

It can be executed on storage servers . According to 1, you can invoke CellCLI by logging in to the Exadata cell as cellmonitor , celladmin , or root user and typing “cellcli” . Within CellCLI , you can perform various management and monitoring tasks for the cell134.

It can be executed using the DCLI utility . According to 5, DCLI (distributed CLI) is another utility that can be used to execute scripts and commands across multiple storage cells from a single interface. You can use DCLI to run CellCLI commands on multiple cells at once54.

The Exadata X9M-2 Extended (XT) Storage Server does not include any Persistent Memory (PMEM) DIMMs. The XT server configuration primarily serves as a cost-effective archival storage option and lacks the performance features available in the HC (High Capacity) and EF (Extreme Flash) storage servers. This configuration does not include Persistent Memory, which is leveraged in other models for accelerating OLTP workloads and providing extremely low-latency data access​​.

In order for an Exadata X9M-2 Elastic Rack to be installed, two power feeds are required for each of the three-phase 24kVA PDUs. A single cable from each PDU will not be enough to power the rack, and neither a splitter cable nor rearrangement of the power cables from the servers to the PDUs will be able to provide sufficient power for the system. Therefore, the installation cannot proceed until two power feeds are available per PDU.
