With a cloud service category where the cloud customer is responsible for deploying all services, systems, and components needed for their applications, which of the following storage types are MOST likely to be available to them? 

Answer options:

A. Structured and hierarchical
B. Volume and object
C. Volume and database
D. Structured and unstructured

B

The question is describing the Infrastructure as a Service (IaaS) cloud offering, and as such, the volume and object storage types will be available to the customer. Structured and unstructured are storage types associated with PaaS, and although the other answers present similar-sounding storage types, they are a mix of real and fake names.
