The correct answer is B. Storage tiering. The CIO requires a storage solution that combines Fibre Channel (FC) and SATA drives in a single array, with data placement managed by performance-driven policies.
Question

Why each option
The CIO requires a storage solution that combines Fibre Channel (FC) and SATA drives in a single array, with data placement managed by performance-driven policies.
Storage provisioning is the process of allocating storage capacity to servers, but it does not inherently manage data movement between different drive types based on performance policies.
Storage tiering automatically moves data between different storage types (e.g., high-performance FC and high-capacity SATA) based on access patterns and predefined performance policies, optimizing both cost and performance within a single storage array.
Dynamic provisioning allows for on-demand allocation of storage space, which is a broader concept than intelligent data movement between tiers.
Dynamic resource allocation typically refers to the flexible assignment of computing resources like CPU or RAM, not the automated movement of data within a storage system.
