In an ONTAP cluster that hosts both SAN and NAS workloads, which volume type grows and shrinks dynamically?

• A. Infinite Volume
• B. FlexGroup Volume
• C. SnapLock Volume
• D. FlexVol Volume

Answer: (D)

FlexVol volumes are the flexible containers in ONTAP that can be resized online as data grows or is reclaimed. They sit inside an aggregate and can be expanded with a vol size increase, or reduced when space is freed (subject to data and snapshot constraints). This dynamic resizing makes them suitable for environments that host both SAN and NAS workloads, since you can allocate LUNs or file systems within the same scalable volume and adjust its capacity as needs change. FlexGroup volumes, on the other hand, are a namespace built from multiple underlying FlexVols to scale out NAS performance; growth happens by adding more member volumes and rebalancing, not by a single volume resizing on the fly. SnapLock volumes are WORM-enabled and have retention controls that typically prevent shrinking. Infinite Volume is not a standard ONTAP construct used for dynamic single-volume growth. So the volume type that grows and shrinks dynamically is FlexVol.
