You are required to support your Oracle RAC configuration using ASM and RAID technology. You plan to discuss the storage configuration with the storage technology team. They have proposed a configuration as shown in the exhibit with a separate set of LUNs for the data disk group and the flash recovery area disk group and a 500 KB stripe size in line with other non-Oracle LUNs. The Data disk group has four 250G LUNs and the FRA disk group has four 500G LUNS, both of which are mirrored.
What are three disadvantages of this configuration? (Choose three.)
A.
Index Range Scans would cause I/O to many different physical disks.
B.
The LUNs are not aligned with ASM Allocation Units, which may lead to I/O bottlenecks.
C.
Retention policies that require backups to be kept for long time periods may cause wasted space due to large allocation units.
D.
I/O to the flash recovery area disk group for backups may cause performance issues when full table scans are occurring during batch workloads.
