When considering the tiering policies associated with a FabricPool-enabled aggregate, the correct three policies are: local-only, auto, and snapshot-only. 'Local-only' keeps data in the local tier, 'auto' moves inactive data to the cloud tier, and 'snapshot-only' moves snapshot data to the cloud tier. The options 'backup' and 'mirror-vault' are not recognized tiering policies associated with FabricPool.
