Which statement properly describes potential allocation for a grid disk?
The correct answer is C. A grid disk can use portions of a cell disk on a subset of cells. Space for grid disks can be allocated in an interleaved manner. Grid disks that use this type of space allocation are referred to as interleaved grid disks. This method attempts to equalize the performance of the grid disks residing on the same cell disk rather than having the…

Explanation
Space for grid disks can be allocated in an interleaved manner. Grid disks that use this type of space allocation are referred to as interleaved grid disks. This method attempts to equalize the performance of the grid disks residing on the same cell disk rather than having the grid disks that occupy the outer tracks getting better performance at the expense of the grid disks on the inner CREATE GRIDDISK ALL PREFIX=prefix--This CELLCLI command automatically creates grid disks on all available Exadata cell disks. Note that the name you provide for prefix should be the same as the disk group name. For example, to create grid disks for your ASM disk group DATA, use the CREATE GRIDDISK ALL PREFIX='DATA' command. Because no size is specified in this example, the grid disk consumes the whole cell disk.
