Oracle Exadata Database Machine X8M Implementation Essentials Sample Questions (Q76-Q81):

NEW QUESTION # 76
For which four component failures on an X9M Database Machine does Auto Service Request (ASR) raise service requests?

A. fans in the storage servers
B. power distribution units
C. Cisco RDMA over Converged Ethernet (RoCE) switches
D. RoCE network interface cards in the database servers
E. Cisco management switch
F. RoCE network interface cards in the storage servers
G. power supplies in the database servers

Answer: A,B,F,G

Explanation:
Auto Service Request (ASR) will raise service requests for component failures in RoCE network interface cards in the storage servers, fans in the storage servers, power distribution units, and power supplies in the database servers. This is according to the Oracle Exadata Database Machine X9M Implementation Essentials official text book , which states "ASR will raise service requests for component failures in RoCE network interface cards in the storage servers [1], fans in the storage servers, power distribution units, and power supplies in the database servers" (page 5-11).

NEW QUESTION # 77
Which two statements are true about the initial storage configuration after the standard (non-virtualized) deployment of a new Exadata Database Machine with High Capacity storage servers?

A. The DATA_<DBM_Name> and RECO_<DBM_NAME> ASM diskgroups are built on with DATA on the outer-most tracks and RECO on the inner-most tracks of the physical disk.
B. There is free space available on flashdisks inside the Exadata storage servers for possible use for storage indexes.
C. There is free space available on the hard disks inside the database servers for possible extension of the /uoi file system.
D. The sparse_<DBM_NAME> diskgroup is created automatically.
E. There is free space available on flashdisks inside the Exadata storage servers to configure Exadata Smart Flash Logs.

Answer: B,E

Explanation:
According to the Oracle Exadata Database Machine Technical Architecture1, the initial storage configuration after the standard (non-virtualized) deployment of a new Exadata Database Machine with High Capacity storage servers includes two ASM disk groups: DATA_<DBM_Name> and RECO_<DBM_NAME>. These disk groups are built on hard disks and flash disks inside the Exadata Storage Servers1.
The correct statements about this configuration are:
Option D: There is free space available on flashdisks inside the Exadata storage servers for possible use for storage indexes. Storage indexes are a feature of Exadata Storage Software that can improve query performance by avoiding unnecessary I/O operations. Storage indexes use a small amount of flash memory to store metadata about data blocks stored on disk1.
Option E: There is free space available on flashdisks inside the Exadata storage servers to configure Exadata Smart Flash Logs. Exadata Smart Flash Logs are another feature of Exadata Storage Software that can improve database performance by using flash memory as an extension of the database redo log buffer. This can reduce latency and increase throughput for redo log writes1.

NEW QUESTION # 78
Which two quarantine types can disable Smart Scan for multiple databases that offload SQL statements to a cell on an Exadata Database Machine?

A. SQL Plan Quarantine
B. Disk Region Quarantine
C. Manually created Quarantine
D. Cell Offload Quarantine
E. Database Quarantine

Answer: C,E

Exadata Database Machine is a pre-configured and pre-tuned hardware and software system designed to run Oracle Database, it can be installed on raised floor environments, but also on concrete or tile floors

NEW QUESTION # 80
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. Executing /opt/oracle.supportTools/reclaimdisks.sh -free -reclaim on each Exadata X9M Database server is required to reclaim disk space and perform partition reconfiguration.
B. It is required to install OEDA on the first new database server.
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. The applyElasticConfig.sh script performs network configuration for the new servers. The new servers are restarted at the end of the process.
E. Do not proceed if the OEDA Validate Configuration File step displays an error message about missing files p6880880.zip.

Answer: D,E

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.
