Oracle Exadata Database Machine X8M Implementation Essentials Sample Questions (Q42-Q47):

NEW QUESTION # 42
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. cellcli (or exacli/exadcli) to examine storage server metrics such as database, category, ceiidisk, and griddisk
  • B. 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
  • C. OS I/O metrics using Enterprise Manager host pages for the storage servers
  • D. OS I/O metrics using OS tools such as iostat on the storage servers
  • E. OS I/O metrics using OS tools such as iostat on the database servers

Answer: A,C

Explanation:
1. OS I/O metrics using Enterprise Manager host pages for the storage servers: Enterprise Manager provides a detailed view of the storage server's performance including I/O metrics and statistics. You can use these metrics to analyze I/O performance and identify any bottlenecks.
2. cellcli (or exacli/exadcli) to examine storage server metrics such as database, category, ceiidisk, and griddisk: These commands are used to gather information about storage server performance, including I/O statistics, disk usage, and resource allocation.


NEW QUESTION # 43
Which two steps concise the path used to communicate with Enterprise Manager from an Exadata Database Machine?

  • A. SNM? traps for alerts are sent by the storage server ILOM to the Enterprise Manager agent.
  • B. SNMP traps for alerts are sent by the storage server RS process to the storage server ILOM.
  • C. SNMP traps for alerts are sent by the storage server ILOM to the storage server is process.
  • D. SNMP traps for alerts are sent by the storage server MS process to the storage server ILOM.
  • E. SNMP traps for alerts are sent by the storage server RS process to the Enterprise Manager agent.
  • F. SNMP traps for alerts are sent by the storage server MS process to the Enterprise Manager agent.
  • G. SNMP traps for alerts are sent by the storage server ILOM to the storage server MS process.

Answer: A,F

Explanation:
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.


NEW QUESTION # 44
Which are two valid reasons for executing an X9M-2 Exadata storage server rescue procedure?

  • A. the failure of physical disk 0 and 11
  • B. the failure of physical disk 1
  • C. moving all disks from one cell to another as part of a chassis-level component failure
  • D. corruption in the / (root) filesystem
  • E. accidental loss of all data from all griddisks in a storage server
  • F. corruption in a normal or high redundancy ASM diskgroup
  • G. the failure of both physical M.2 disks

Answer: A,D

Explanation:
The rescue procedure is necessary when system disks fail, the operating system has a corrupt file system, or there was damage to the boot area. If only one system disk fails, then use CellCLI commands to recover. In the rare event that both system disks fail simultaneously, you must use the Exadata Storage Server rescue functionality provided on the Oracle Exadata Storage Server Software CELLBOOT USB flash drive.


NEW QUESTION # 45
You have been asked to design a backup solution for an Exadata X9M-2 Quarter Rack with Extreme Flash Storage Servers connected to a new ZFS Storage Appliance ZS7 with 2 Storage Controllers with 100Gb Ethernet cards and 3 Storage Trays. You are using Oracle Exadata Configuration Assistant to validate the rack layout.
1. Use "Add Equipment" to add the Exadata X9M EF Storage Servers, starting from RU10.
2. Use drop down to add ZFS Storage Appliance Controllers.
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. 10, 8, 2, 5
  • B. 7,6,9,11
  • C. 4,1, 6, 9
  • D. 10, 8, 9, 11
  • E. 0

Answer: D

Explanation:
The correct order of steps is 10, 8, 9, 11. The 10th step is to use the drop down to add Exadata X9M Database Servers, the 8th step is to use the drop down to add Exadata X9M EF Storage Servers, the 9th step is to use "Add Equipment" to add the ZFS Storage Controllers, and the 11th step is to use "Add Equipment" to add the ZFS Storage Trays. These steps are referenced in the Oracle Exadata Database Machine X9M Implementation Essentials Official Textbook, which is available online at https://docs.oracle.com/cd/E80437_01/E80437/html/index.html.

Recently, you discovered that certain asmdisks were offline in one of the diskgroups used by the rac database called prod.
In which two sources would you find diagnostic messages related to this problem?

  • A. alert logs for Enterprise Manager
  • B. Enterprise Manager Alerts on the ILOM home page for cell connectivity problems for the prod database instances
  • C. alert logs for the ASM instances
  • D. alert logs for the prod database instances
  • E. Enterprise Manager Alerts on the Exadata Storage Server Grid home page

Answer: B,E
