Your customer is planning a Scality RING solution.

The correct answer is A because Scality RING is positioned by HPE as a scale-out object and file storage solution built on qualified HPE server platforms, including HPE Alletra Storage Server models. For a customer planning approximately 750 TB of usable software-defined storage, the design focus is the validated HPE server configuration, drive type, usable-capacity target, and Scality license sizing. HPE documentation describes the Scality RING solution as consisting of HPE server systems, Scality license and maintenance, and installation services, with licensing based on unique usable data capacity. The minimum RING configuration is not 1000 TB; HPE references a lower starting usable-capacity threshold, so option B is incorrect. Option D is also incorrect because Scality solutions and licenses are explicitly available through HPE solution packaging. Option C is not the best design statement for this customer use case because the key technical validation is platform support and capacity alignment, not a generic claim about lower-cost licensing. This maps directly to the course topic covering scale-out unstructured data platforms, including Scality, Qumulo, Cohesity, and related HPE storage-server designs.
