Explanation
Hitachi Device Manager (HDvM) is a centralized storage provisioning and management tool focused on volume lifecycle operations. Allocate volumes (A) assigns storage volumes to hosts, unallocate volumes (B) removes those host-to-volume assignments, and create volume (E) provisions new logical volumes on the storage array - these three together represent the fundamental volume lifecycle that HDvM is designed to manage.
C (compress) and D (dedupe) are wrong because data reduction features like compression and deduplication are storage efficiency functions handled at the array firmware/hardware level (e.g., on VSP systems), not provisioning operations exposed through Device Manager's management interface.
Memory tip: Think of HDvM as handling the CUA lifecycle - Create, Unallocate, Allocate. It manages who gets what storage and when, not how the data is physically stored internally.
