Which statement correctly describes the relationship between aggregates and volumes in ONTAP?

• A. A volume contains multiple aggregates.
• B. An aggregate is created from existing volumes.
• C. A volume supplies performance to an aggregate.
• D. An aggregate provides the storage capacity for one or more volumes.

Answer: (D)

In ONTAP, aggregates act as the storage pool formed by a collection of physical disks with a chosen RAID/configuration, and volumes are created inside that pool to hold usable data. Because volumes draw their space from the aggregate’s capacity, the aggregate provides the storage capacity for one or more volumes. The other statements don’t fit: a volume doesn’t contain aggregates, and aggregates aren’t created from existing volumes. Performance is a characteristic of the aggregate’s disk configuration and overall I/O paths, not something a single volume supplies to the aggregate.
