Which NetApp product offers a cloud-native service for data transfer and synchronization?

The option that best describes a cloud-native service for data transfer and synchronization is the Cloud Sync service. This product is designed specifically to enable efficient data synchronization between on-premises storage and cloud services or between different cloud providers.

Cloud Sync provides capabilities such as automatic data replication, which facilitates real-time synchronization of data across environments. This is especially beneficial for organizations looking to maintain consistency and leverage cloud resources effectively, as it supports various protocols and locations for transferring data seamlessly.

In contrast, the other options serve different purposes. Cloud Insights is focused on performance monitoring and optimization of cloud resources rather than data transfer. Cloud Tiering is aimed at optimizing storage costs by moving less frequently accessed data to lower-cost storage environments. Cloud Compliance service is designed to ensure that data management practices adhere to regulatory standards, rather than facilitating data transfer and synchronization. Thus, the Cloud Sync service stands out as the proper solution for the requirement of data transfer and synchronization in a cloud-native context.
