Which option is NetApp's pay-as-you-grow storage-as-a-service offering for critical NFS and FCP data?

• A. Astra Control
• B. Keystone
• C. Azure NetApp Files
• D. Cloud Volumes ONTAP

Answer: (B)

Keyst​one is NetApp’s pay-as-you-grow storage-as-a-service option, designed to deliver on-demand capacity for mission-critical NFS and Fibre Channel data with consumption-based pricing. It lets you scale storage up or down as needed without large upfront investments, aligning with a flexible, service-based model managed or supported by NetApp.

Astra Control is about data management for Kubernetes workloads, not a general pay-as-you-grow storage service. Azure NetApp Files is a cloud-native file service in Azure for NFS/SMB, while Cloud Volumes ONTAP is the ONTAP software that runs in the cloud or on premises—both different delivery models, not the specific pay-as-you-grow service described.
