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

What are two recommended configuration best practices for backup and recovery on Exadata?

• A.The internal Recovery Appliance backup and restore processing is optimized when the RMAN FILESPERSET parameter is set to 1 for the level 1 incremental backup set.
• B.Even if the backup was limited to writing to four tape drives, eight channels could be specified to expedite the restore process.
• C.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.
