As a system administrator, you perform a routine check of available storage space on your FAS2750. You notice that the vol_1 volume is approaching 100% capacity. The volume is configured with the space guarantee set to volume and the LUN reservation is disabled. You want to free up space in the volume without increasing its size.
Which action would accomplish this task?
A. Increase the size of the LUN.
B. Increase the Snapshot Reserve.
C. Increase the aggregate size.
D. Use deduplication.
D is the correct answer. This is a NAS volume, and deduplication is the only way to decrease usage without increasing the size of the volume.
