Oracle Exadata Database Machine X8M Implementation Essentials Sample Questions (Q83-Q88):

NEW QUESTION # 83
Exadata X9M enables virtualization using KVM. Which statement is true about virtualization on Exadata X9M?

  • A. Virtual guests from X8 and earlier can be migrated to X9M using VM Guard.
  • B. Up to 12 virtual guests per X9M-2 database server are supported. If the database server memory has 384GB and Exadata Secure RDMA Fabric isolation is configured 8 guests are supported
  • C. Up to 12 virtual guests per X9M-2 database server are supported.
  • D. Oracle KVM Manager should be installed on at least two Database servers per Exadata rack.
  • E. Exadata X9M-8 supports up to 48 virtual guests regardless if Exadata Secure RDMA Fabric Isolation is configured.

Answer: C

Explanation:
Oracle Exadata X9M-2 supports virtualization through Kernel-based Virtual Machine (KVM), enabling multiple virtual machines (VMs) to run on each database server. Specifically:
Each X9M-2 database server can support up to 12 virtual guests. This number provides ample flexibility for running various applications or Oracle Real Application Clusters (RAC) instances across virtualized environments .
While Exadata X9M-8 supports even more extensive virtualization, this question focuses on the X9M-2 model. The specified limitation of 12 guests per database server considers both system resource allocation and performance optimization .


NEW QUESTION # 84
Which two statements are correct about adding an additional database server to a physical Exadata X9M Database Machine using Oracle Exadata Deployment Assistant (OEDA)?

  • A. Do not proceed if the OEDA Validate Configuration File step displays an error message about missing files p6880880.zip.
  • B. The applyElasticConfig.sh script performs network configuration for the new servers. The new servers are restarted at the end of the process.
  • C. In order to configure the servers with Oracle Exadata Deployment Assistant (OEDA), the new server information must be entered in OEDA, and the configuration file must contain existing nodes.
  • D. Executing /opt/oracle.supportTools/reclaimdisks.sh -free -reclaim on each Exadata X9M Database server is required to reclaim disk space and perform partition reconfiguration.
  • E. It is required to install OEDA on the first new database server.

Answer: A,B

Explanation:
It is not necessary to execute /opt/oracle.supportTools/reclaimdisks.sh -free -reclaim on each Exadata X9M Database server, nor is it required to install OEDA on the first new database server. In order to configure the servers with Oracle Exadata Deployment Assistant (OEDA), the new server information must be entered in OEDA, and the configuration file must contain existing nodes.
Search results: [1] Refer to the Oracle Exadata Database Machine X9M Implementation Essentials documentation for more information on adding an additional database server to a physical Exadata X9M Database Machine using Oracle Exadata Deployment Assistant (OEDA). [2] Oracle Exadata Deployment Assistant (OEDA) is a graphical user interface (GUI) tool used to configure the Oracle Exadata Database Machine X9M. [3] This article provides the step-by-step instructions to add an additional database server to a physical Exadata X9M Database Machine using Oracle Exadata Deployment Assistant (OEDA). [4] It is important to run the OEDA Validate Configuration File step prior to adding the new server to ensure the configuration file is valid and that all required files exist. [5] When adding a new database server with OEDA [1], the configuration file must contain the existing nodes and the new server information must be entered in OEDA. [6] The applyElasticConfig.sh script must be executed to configure the new servers, after which the new servers will be restarted.

Answer: A,B

Explanation:
The execute /opt/oracle.supportTools/reclaimdisks.sh -free -reclaim on each Exadata X9M Database server is required to reclaim disk space and perform partition reconfiguration.
The applyElasticConfig.sh script performs network configuration for the new servers. The new servers are restarted at the end of the process.


NEW QUESTION # 86
You are concerned about the operating temperature of the database servers in your Exadata Full Rack and want to be alerted if the server exceeds 30C.
What command should use use to generate alerts for such an event?

  • A. dbmcli -e "set alert ds_temp> 30" on each database server
  • B. dbmcli -e "set threshold ds_temp comparison=' >', critical=30" on each database server
  • C. dbmcli -e "alert metriccurrent ds_temp where metricValue > 30" on each database server
  • D. dbmcli -e "create threshold ds_temp comparison='>', critical=30" on each database server

Answer: D

Explanation:
According to Oracle's documentation1, to set a threshold for a metric on a database server, you need to use the create threshold command with the appropriate parameters. The set threshold command is used to modify an existing threshold2.
Therefore, the command that you should use to generate alerts for such an event is:
dbmcli -e "create threshold ds_temp comparison='>', critical=30" on each database server1


NEW QUESTION # 87
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. 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. cellcli (or exacli/exadcli) to examine storage server metrics such as database, category, ceiidisk, and griddisk
  • D. OS I/O metrics using OS tools such as iostat on the database servers
  • E. OS I/O metrics using OS tools such as iostat on the storage servers

Answer: B,C

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 *p1us . These views can help you monitor the I/O activity and latency at the file, function, and consumer group level.
