Identify three valid reasons for creating multiple griddisks on a single harddisk-based celldisk. 

Answer options:

A. to implement storage realms so that storage that can be reserved for specific resource consumer groups in the same database
B. to enable the creation of normal or high redundancy ASM diskgroups
C. to segregate storage into multiple pools with different performance characteristics
D. to enable disk mirroring for the system area
E. to implement storage realms so that storage can be reserved for specific databases
F. to implement storage realms so that storage that can be reserved for specific Grid Infrastructure

Creating multiple grid disks per cell disk allows you to create multiple pools of storage on the same Exadata Storage Server. The multiple grid disks can be assigned to separate ASM diskgroups, which can be provisioned to different databases. Note: Griddisk is a logical disk that can be created on a celldisk. In a standard Exadata deployment we create griddisks on hard disk based celldisks only. While it is possible to create griddisks on flashdisks, this is not a standard practice. F: After you complete the cell configuration, you can perform the following optional steps on the storage cell: ✑ Add the storage cell to the Exadata Cell realm ✑ Configure security on the Oracle Exadata Storage Server grid disks References: https://docs.oracle.com/cd/E80920_01/SAGUG/SAGUG.pdf
