Which statement describes the role of Azure Blob Storage when using Cloud Volumes ONTAP in Azure?

• A. Primary storage for system data
• B. Capacity tiering for cold data
• C. Hardware encryption
• D. DNS resolution

Answer: (B)

Azure Blob Storage is used as the capacity tier for cold data when Cloud Volumes ONTAP runs in Azure. The active data stays on the CVO VM’s local, high-performance storage for fast I/O, while less frequently accessed data is moved to Azure Blob to save space and reduce costs. When that cold data is needed again, ONTAP retrieves it from the blob automatically, so users see a seamless volume access without worrying about where the data actually resides. This role isn’t about being the primary storage for system data, encrypting data as the main function, or handling DNS resolution—those functions are addressed by other parts of the stack.
