NetApp Cloud Volumes ONTAP provides several storage efficiency features that help optimize cloud storage costs. Two of the key methods for reducing costs are:
* Thin Provisioning: This feature allows users to allocate more storage capacity than is physically available. Instead of reserving full storage at the time of volume creation, space is only consumed as data is written. This reduces upfront costs and optimizes storage use by delaying actual storage allocation until necessary, making it cost-effective.
* Volume Deduplication: Deduplication removes redundant copies of data within a volume, reducing the total storage footprint. By eliminating duplicate blocks of data, volume deduplication significantly cuts down on the amount of storage consumed, leading to lower storage costs in the cloud environment.
Other options like "aggregate deduplication" and the "TCO calculator" are not direct methods to optimize storage costs. Aggregate deduplication is not as granular as volume deduplication, and the TCO calculator is a tool for estimating total cost, not a method for optimization.

For anAFF MetroCluster IPconfiguration, the customer should useFabricPool mirrorto tier cold data to the public cloud. FabricPool is a feature of ONTAP that allows automatic tiering of cold or inactive data from high-performance AFF (All-Flash FAS) systems to a lower-cost cloud-based object storage. It is designed to extend the capacity of on-premises systems by tiering cold data to cloud storage, reducing the need for additional local storage.
Other options likeBlueXP copy and sync (B)andBlueXP replication (C)are related to data replication and migration, not specifically tiering of inactive data.SyncMirror (D)is a high-availability feature used for synchronous replication, not for cloud tiering.
