Oracle Exadata Database Machine X8M Implementation Essentials Sample Questions (Q63-Q68):

NEW QUESTION # 63
What are two recommended configuration best practices for backup and recovery on Exadata?

Answer: A,B

Explanation:
A recommended configuration best practice for backup and recovery on Exadata is to place the backup network on dedicated switches installed in the top of the rack (ToR). This provides a greater level of control and isolates the backup network from other workloads. Additionally, even if the backup is limited to writing to four tape drives, it is recommended to specify eight channels to expedite the restore process.
Another best practice is to set the RMAN FILESPERSET parameter to 1 for the level 1 incremental backup set. This will optimize the internal Recovery Appliance backup and restore processing. Finally, if off-site long-term backup retention is needed, Oracle Database Backup Cloud Service should be used as a low-cost, offsite scalable storage solution for a disaster recovery solution.


NEW QUESTION # 64
You have configured a multirack Database Machine with two X9M-8 full racks all in a single cluster and storage grid comprising a total of 4 X9M-8 Database servers and 28 X9M-8 Storage servers.
Which two options are true regarding the servers on which Enterprise Manager agents must be deployed in order to monitor all components of this multirack configuration?

Answer: C,G

Explanation:
In order to monitor all components of this multirack configuration, Enterprise Manager agents must be deployed on at least two storage servers in both racks and all database servers in both racks. This is according to the Oracle Exadata Database Machine X9M Implementation Essentials official text book [1], in which it states "To monitor all components of the multirack configuration, you must deploy agents on all database servers and at least two storage servers in each rack" (page 6-15).

NEW QUESTION # 67
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?

Answer: D

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.
For more information about power requirements for Exadata X9M-2 Elastic Racks, refer to the Oracle Exadata Database Machine X9M Implementation Essentials official text book and resources.
