Oracle Exadata Database Machine X8M Implementation Essentials 認定 1Z0-902 試験問題 (Q18-Q23):

質問 # 18
Your customer needs to ensure that their data is available on the Exadata machine during updates. The customer wants to be able to update one server at a time but still be protected against single-node server failure.
What ASM redundancy level should they use?

A. Sparse
B. High
C. External
D. Normal
E. Extended

正解：B

解説：
https://www.oracle.com/technetwork/database/exadata/maa-exadata-asm-cloud-3656632.pdf According to the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book, the customer should use the High redundancy level for their ASM storage in order to ensure that their data is available on the Exadata machine during updates. The High redundancy level provides the most protection against single-node server failure, as it stores three copies of each data file on separate nodes. This is the same redundancy level used for the Oracle Database's Control Files and Redo Logs. Instructions for configuring the ASM redundancy level can be found in the book and can be referenced here: https://docs.oracle.com/cd/E80920_01/E80920/html/x9m_asm_overview.html.

質問 # 19
Which three statements are true about Oracle Configuration Manager (OCM) for an Exadata Database Machine?

A. Collected configuration information can be uploaded automatically to Oracle.
B. It is mandatory to install OCM on at least one database server.
C. It collects configuration information on demand.
D. It collects configuration information automatically.
E. Collected configuration information can be uploaded manually to Oracle.
F. It is mandatory to install OCM on all database servers.

正解：A、C、D

解説：
It collects configuration information automatically (B). OCM gathers detailed configuration information about a variety of designated Oracle products and components across an enterprise on a regular basis2.
It collects configuration information on demand . OCM can also collect configuration information manually when requested by the user or by Oracle Support2.
Collected configuration information can be uploaded automatically to Oracle (E). OCM can upload the collected configuration information to My Oracle Support automatically for analysis and support purposes3.

質問 # 20
You have been asked to investigate why an Exadata Database Server stopped communicating on the client network for 10 minutes over the past weekend.
Which command would help investigate this?

A. # /opt/oracle.ExaWatcher/GetExaWatcherResults.sh -from <Fridays_Date>_17:00:00 -to <Sundays_Date>_23:59:00
B. # /opt/oracle.SupportTools/exachk/exachk -from <Fridays_Date>_17:00:00 -to <Sundays_Date>_23:59:00
C. # /opt/oracle.SupportTools/ibdiagtools/netcheck/runDiagnostics.pm -from <Fridays_Date>_17:00:00 -to <Sundays_Date>_23:59:00
D. $ ${ORACLE_HOME}/suptools/tfa/release/tfa_home/bin/tfact1 -from <Fridays_Date>_17:00:00 -to <Sundays_Date>_23:59:00

正解：B

解説：
Exachk is an Oracle-provided diagnostic tool that allows you to check various components of an Exadata Database Server, including the client network. The tool is located in the /opt/oracle.SupportTools/exachk/ directory and can be run with the command: exachk. This command can be run with the option -from <Fridays_Date>_17:00:00 and -to <Sundays_Date>_23:59:00 to specify a time range of interest, this way you can check the client network status between the specified time range. The tool checks the status of various components such as network interfaces, InfiniBand fabric, and storage servers. It also analyzes log files, configuration files, and system settings to detect any issues. The tool generates a report, which can be used to identify the root cause of the issue and provide recommendations for resolution.
Tfact1 is a tool to collect diagnostic information from Exadata and non-Exadata systems and it is not related to client network status.
Netcheck and GetExaWatcherResults.sh are not tools provided with the Exadata Database Server and they are not related to client network status.

質問 # 21
Which two statements are true about enabling write-back flash cache?

A. Write-back Flash Cache cannot be used on Extreme Flash Storage Servers.
B. When enabling write-back flash cache in a non-rolling manner, you need to drop the Persistent Memory Commit Accelerator (PMEMLog) first.
C. Before write-back flash cache is enabled, you need to drop the Flash Cache first.
D. Write-back flash cache is on by default for High Capacity Storage Servers in High Redundancy configurations.
E. When enabling write-back flash cache in a rolling manner, DBCLI should be used to inactivate the grid disks on all cells first.

正解：C、E

解説：
The two statements that are true about enabling write-back flash cache are:
When enabling write-back flash cache in a rolling manner, DBCLI should be used to inactivate the grid disks on all cells first.
Before write-back flash cache is enabled, you need to drop the Flash Cache first.
The Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book states that "when enabling write-back flash cache in a rolling manner [1], grid disks need to be inactivated on all cells before enabling write-back flash cache". It also states that "before write-back flash cache can be enabled, the existing flash cache must be dropped".

質問 # 22
In order two support a new application, you are planning to add a RAC VM cluster to an existing Oracle Exadata X9M-2 deployment.
Which two methods can be considered?

A. Use domu_maker utility.
B. Use the xm command.
C. Use the OEDA web-based configuration tool.
D. Use the OEDA Command line interface.
E. Use Oracle VM Manager.

正解：C、D

解説：
For adding a new RAC (Real Application Clusters) VM cluster to an existing Oracle Exadata X9M-2 deployment, you can utilize the Oracle Exadata Deployment Assistant (OEDA). OEDA is available in two interfaces:
OEDA Web-based Configuration Tool: This web-based interface facilitates the configuration of Exadata environments, supporting both physical and virtual deployments. The graphical interface helps in defining VM clusters, including RAC clusters, and ensures the configuration aligns with Oracle best practices.
OEDA Command Line Interface (CLI): For more advanced or automated tasks, the command-line interface (oedacli) allows for precise control over the deployment process. It supports various configuration actions such as adding or removing clusters, resizing ASM disk groups, and managing VM clusters.
These tools are specifically designed for Exadata configurations and provide a streamlined approach for deploying and managing RAC clusters in both physical and virtualized environments.
