A new storage network is being designed. Which of the following would be the MOST appropriate process to address storage planning?

A disk to disk to tape grandfathering scheme describes a backup strategy, not a holistic storage planning process for a new storage network design.

A tiered approach, which matches data access frequency and performance needs with different storage types (online for frequent access, near-line for less frequent, and offline for archival), is a fundamental and most appropriate strategy for comprehensive storage planning and cost optimization.

A Virtual Tape Library with multi-pathing and high-speed connectivity describes a specific backup infrastructure component and its features, not a comprehensive process for overall storage planning.

Fixed data retention periods relate to data lifecycle management and compliance, which is a part of storage planning but not the most appropriate process to address the overall design of a new storage network.
