Oracle Updated 1z0-902 Exam Questions and Answers by aysha

The given command uses a for loop with ipmitool to issue ping commands sequentially to a range of IP addresses in the management network:

for j in {01..23}; do ipmitool sunoem cli "set /SP/network/test ping=192.168.1.1$j"; done

This script verifies the connectivity of the ILOM management network before the Exadata installation. Each server’s Service Processor (SP) is tested for reachability, confirming that the management network setup is operational across the full rack .

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.

This command is based on the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book and other resources. This command sets the power state of the system to ON and starts the storage server. It is the only command that is able to start the storage server remotely. All the other commands are incorrect or require the user to be physically present in the data center.

According to the Oracle Exadata Database Machine documentation12, two recommended configuration best practices for backup and recovery on Exadata are:

A. Placing the backup network on dedicated switches installed in the top of the rack (ToR) has the benefits of isolating the backup network from other workloads and providing a greater level of control.

D. When off-site long-term backup retention is needed, use Oracle Database Backup Cloud Service as a low-cost, offsite scalable storage for a disaster recovery solution.
