What Is a recommended setting for using the NetApp ONTAP LUN fractional reserve?

ALUN space reservation is disabled.

BSpace allocation is set to enable.

CSpace guarantee is set to volume.

DVolume Snapshot copy automatic deletion is disabled.

Suggested Answer: C

The recommended setting for using the NetApp ONTAP LUN fractional reserve is to set the space guarantee to 'volume'. This setting ensures that the required space for overwrites in the volume is reserved, preventing potential write failures when snapshot copies are created. This setup helps in maintaining the performance and reliability of the storage system by ensuring there is always enough space allocated for the LUN.
