3. You cannot add ZFS Storage Appliance to an Exadata Rack.
4. Use "Add Equipment" to add the ZFS Storage Trays, starting from RU1.
5. Use drop down to add ZFS Storage Trays.
6. Use "Add Equipment" to add the Exadata X9M Database Servers, starting from RU16.
7. Use "Add Equipment" to add the Exadata X9M EF Storage Servers, starting from RU1.
8. Use drop down to add Exadata X9M EF Storage Servers.
9. Use "Add Equipment" to add the ZFS Storage Controllers, starting from RU27.
10. Use drop down to add Exadata X9M Database Servers.
11. Use "Add Equipment" to add the ZFS Storage Trays, starting from RU31.
Which of these steps are correct and what is their correct order?

A. 0
B. 7,6,9,11
C. 10, 8, 2, 5
D. 44, 6, 9

NEW QUESTION # 69
Which three component faults are covered by Oracle Auto Service Request (ASR)?

A. System Controller (SC)
B. Fan trays
C. Proactive recommendations for firmware
D. I/O boards
E. File system unmounted
F. RoCE network interface cards

Answer: A,B,D

Explanation:
Oracle ASR covers a range of hardware components on Exadata Database Machines to ensure rapid response and issue resolution. The covered hardware components include critical parts such as:
Fan Trays: These are essential for cooling Exadata components and are covered by ASR in case of failures.
System Controller (SC): Integral to the operation of Exadata storage servers, SC failures are reported by ASR to ensure the overall system's reliability and availability.
I/O Boards: ASR actively monitors and responds to failures in I/O boards, which are crucial for data processing and connectivity within Exadata storage servers.
The ASR system is optimized to handle hardware-related issues proactively, ensuring that critical components are continuously monitored and replaced as necessary.

NEW QUESTION # 70
A new Exadata Quarter Rack with 2 Database Servers and 3 HC Storage Servers and 3-phase 15kVA PDUs is being installed in a Data Center. However, the Data Center is only providing enough power for a single cable from each PDU.
Which statement is correct?

A. The power cables from the servers to the PDUs can be rearranged inside the rack following OECA guidance to utilize a single PDU power cable.
B. A splitter cable can be used to provide power to all PDU cables.
C. The installation can go ahead, no change is required.
D. The installation cannot proceed until two power feeds are available per PDU.

Answer: C

Explanation:
According to the Oracle Exadata Database Machine X9M-2 Data Sheet1, each PDU has two power input cables that can be connected to separate power sources for redundancy. However, if only one power source is available per PDU, then a single cable can be used to provide sufficient power for normal operation.
