What technology is used to encrypt the data at rest in NetApp Cloud Volumes Service for Google Cloud?

The correct technology used to encrypt data at rest in NetApp Cloud Volumes Service for Google Cloud is NetApp Volume Encryption (NVE). This encryption method is specifically designed to protect data stored within volume-level resources. NVE ensures that all data written to the volume is automatically encrypted using standards of encryption that align with industry best practices.

Volume-level encryption is particularly crucial in a cloud environment, as it enables granular control and enhances security measures by ensuring that sensitive data is protected, even if the physical storage media is compromised. When data is encrypted at the volume level, it not only secures the data but also facilitates compliance with various regulatory requirements.

This choice stands out as it directly addresses the need for encrypting data at rest within the NetApp Cloud Volumes Service, making it an essential feature for users concerned with data privacy and security in cloud deployments.
