A production Oracle database with a high transaction rate recently experienced slow performance.
The storage for the database is on an EMC Symmetrix VMAX and is laid out according to best practice principles. Further investigation found that there was a physical drive failure affecting one of the storage volumes where the database was stored. The database volumes were on RAID 5 metavolumes.
The database administrator is concerned that the RTO will not be met in the future if a database recovery was required at the same time as a drive failure. To meet the RTO, which change to the environment is recommended?

A.
Migrate the database to metavolumes with RAID 1 protection

B.
Migrate the database to metavolumes with RAID 6 protection

C.
Double the number of front-end adapters mapped to the existing metavolumes

D.
Double the number of HBAs in the servers
