Oracle Exadata Database Machine X8M Implementation Essentials Sample Questions (Q25-Q30):

NEW QUESTION # 25
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 installation cannot proceed until two power feeds are available per PDU.
B. The installation can go ahead, no change is required.
C. 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.
D. A splitter cable can be used to provide power to all PDU cables.

Answer: A

Explanation:
An Exadata Quarter Rack with 2 Database Servers and 3 HC Storage Servers and 3-phase 15kVA PDUs would typically require two power feeds per PDU, one for each of the two power distribution units (PDUs) in the rack. A single power feed per PDU is not sufficient to provide the necessary power to the servers and storage in the rack.

NEW QUESTION # 26
An Exadata X9M-2 Elastic Rack with 4 Database Servers and 8 HC Storage Servers and 3-phase 24kVA 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 installation cannot proceed until two power feeds are available per PDU.
B. The installation can go ahead, no change is required.
C. 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.
D. A splitter cable can be used to provide power to all PDU cables.

Answer: A

Explanation:
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.

NEW QUESTION # 27
Examine this list of software components:
1. Oracle KVM Guest
2. Oracle Enterprise Manager Agent (OMA)
3. ASM instance
4. RDBMS instance
5. Automatic Diagnostic Repository Command Interpreter (ADRCI)
6. CELLCLI
7. Cell Server(CELLSRV)
8. diskmon
9. Restart Server (RS)
10. Management Server (MS)
What is the correct location where these software components can run in the standard Exadata Database Machine deployment?

A. 1, 2, 3, 4, 5, 8, 9 and 10 run on the database servers; 5, 6,7, 9 and 10 run on the Exadata storage servers.
B. 1, 2, 3, 4, 9 and 10 run on the database servers; 5, 6, 7, 8, 9, and 10 run on the Exadata storage servers.
C. 3, 4, 8, and 10 run on the database servers; 1, 2, 5, 6, 7 and 9 run on the Exadata storage servers.
D. 2, 3, 4, 8, and 10 run on the database servers; 1, 5, 6, 7and 9 run on the Exadata storage servers.
E. 1, 2, 3, 4, 8 and 9 run on the database servers; 5, 6, 7, 9 and 10 run on the Exadata storage servers.

Answer: E

Explanation:
Oracle KVM Guest, Oracle Enterprise Manager Agent (OMA), RDBMS instance, Automatic Diagnostic Repository Command Interpreter (ADRCI), CELLCLI, diskmon, and Restart Server (RS) can all run on the database servers. The Cell Server (CELLSRV) and Management Server (MS) can both run on the Exadata storage servers. Specific instructions for installing and configuring these software components can be found in the book and can be referenced here: https://docs.oracle.com/cd/E80920_01/E80920/html/x9m_software_components.html.

NEW QUESTION # 28

NEW QUESTION # 29
I/O performance of the prod database on your Exadata Database Machine has degraded slightly over the past month. The database has been allocated to the OLTP I/O Resource Management (IORM) category.
Which two monitoring tools might be useful in examining I/O performance for the prod database?

A. OS I/O metrics using Enterprise Manager host pages for the storage servers
B. OS I/O metrics using OS tools such as iostat on the database servers
C. cellcli (or exacli/exadcli) to examine storage server metrics such as database, category, ceiidisk, and griddisk
D. I/O-specific dynamic performance views such as v$iostat_fiie, v$iostat_function, and v$iostat_consumer_group from the prod database instances using SQL *p1us
E. OS I/O metrics using OS tools such as iostat on the storage servers

Answer: C,D

Explanation:
According to the Oracle documentation1, two monitoring tools that might be useful in examining I/O performance for the prod database are:
cellcli (or exacli/exadcli) to examine storage server metrics such as database, category, ceiidisk, and griddisk (D). This tool can help you monitor the I/O Resource Management (IORM) metrics and identify any bottlenecks or imbalances in the storage layer.
I/O-specific dynamic performance views such as v$iostat_fiie, v$iostat_function, and v$iostat_consumer_group from the prod database instances using SQL *plus. These views can help you monitor the I/O activity and latency at the file, function, and consumer group level.
