                                          At present, the 1Z0-902 exam requires a passing score of 65% and costs $245 USD to register. Oracle controls both figures, so confirm them on the official site before you book.

                                          The latest exam information lists 60-90 questions for the 1Z0-902 exam, to be completed in 120 minutes minutes. Rehearsing under these conditions in the online engine is the closest thing to sitting the real test.

                                          The Oracle Exadata Database Machine X8M Implementation Essentials blueprint is organized into these principal domains:

                                          • High Availability and Maintenance
                                          • Exadata Architecture and Components
                                          • Monitoring and Diagnostics

                                          Question #4

                                          You plan to monitor the status of the motherboard, memory, power, fans, and network cards on the database nodes in your Exadata Database Machine using Enterprise Manager.
                                          Where must you set the thresholds for these hardware components and why, to assure that sensor readings, faults, and any related alerts, are visible in Enterprise Manager?

                                          • A. No thresholds need to be set because they are preset in the ILOM and these are sufficient for monitoring.
                                          • B. Set thresholds in ILOM and in Enterprise Manager because they are not preset anywhere and must be set in both places.
                                          • C. Set thresholds only in ILOM because they are not preset anywhere but need to be set only in ILOM.
                                          • D. No thresholds need to be set because they are preset in the ILOM and in Enterprise Manager
