NetApp Exam NS0-604 Topic 4 Question 19 Discussion

The customer is using 30TB of capacity in NetApp Cloud Volumes ONTAP but only 10TB of this capacity is actively in use. The most cost-efficient solution in this case is to implement data tiering and optimization. Data tiering moves inactive or cold data to lower-cost storage (such as object storage in Azure), while keeping frequently accessed data on higher-performance storage. This strategy allows the customer to reduce costs by only paying for premium storage for the data that is actively in use, while moving less frequently accessed data to a cheaper storage tier.

Storing all data in the premium storage tier (A) would increase costs rather than reduce them. BlueXP backup and recovery (B) is for data protection, not cost optimization. Deploying an additional single-node Cloud Volumes ONTAP instance (D) would increase storage costs rather than optimize them.
