How do ASM failure groups provide redundancy?

B.Failure groups are created for each grid disk to ensure mirror copies are written to the same storage server for faster recovery after a physical disk failure.

C.Failure groups contain all ASM disks in a single storage server preventing mirror copies being written to the same storage server.

D.Extended Redundancy mirrors data across data centers providing the highest levels of data protection.

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.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.
