Which statement regarding the use of NetApp Cloud Tiering policies is true?

The use of NetApp Cloud Tiering policies is designed to optimize storage costs and performance by intelligently managing data based on its access patterns. The correct answer highlights the function of the 'auto tiering' policy effectively.

The 'auto tiering' policy is specifically intended for handling large datasets that are infrequently accessed, allowing less critical data to be automatically moved to less expensive cloud object storage. This approach ensures that organizations can manage storage resources efficiently, storing only the most frequently accessed data in higher-performance storage systems while capitalizing on cost-effective options for data that is accessed less often.

In contrast, the other options incorrectly describe the purpose or usage of the 'all tiering' or 'auto tiering' policies. The 'all tiering' policy generally refers to moving entire volumes to cloud storage, which does not align with the needs of managing large datasets that require selective data placement based on access frequency. Therefore, selecting the 'auto tiering' policy for datasets that are not accessed regularly is the correct strategy for leveraging NetApp’s capabilities in cloud storage management.
