In OpenStack, Cinder is not a storage technology itself.

The statement is TRUE . Official OpenStack documentation describes Cinder, the Block Storage service, as providing on-demand, self-service access to block storage resources via abstraction and automation on top of other block storage devices . That wording is important because it shows that Cinder is not itself a physical storage technology . Instead, it presents a unified service layer that works with many different backend storage systems through drivers.

OpenStack storage architecture documentation also explains that Block Storage supports multiple back ends in the form of drivers , and the actual storage implementation depends on the chosen backend technology. In other words, Cinder exposes APIs and management functions for volumes, snapshots, and related features, while the real block storage is delivered by backend platforms such as SAN, distributed storage, or vendor storage arrays.

This matches Huawei Cloud Stack storage concepts as well, where cloud services are typically built on an abstraction layer to unify heterogeneous resources. Therefore, the correct answer is A (TRUE) , because Cinder serves as an abstraction and orchestration layer over underlying block storage systems rather than being the storage technology itself.
