ISC2 Certified Cloud Security Professional (CCSP) Practice Question

Ephemeral (instance-local) storage is physically attached to the hypervisor host and is automatically wiped when the virtual machine or container host is stopped or terminated, satisfying the requirement that no residual data remain. Because it is included with the compute instance, it avoids the additional charges associated with persistent block or managed file storage services, meeting the cost constraint. Persistent block storage with provisioned IOPS and managed file shares retain data after the instance is terminated, violating the destruction requirement, while long-term archival object storage is intended for infrequently accessed data and would both increase cost and fail to ensure automatic deletion when the container ends.
