Tiered Storage — Microsoft Azure Solutions Architect (AZ-305) Practice Questions
Tiered storage in Azure Blob Storage provides three access tiers, Hot, Cool, and Archive, each carrying different costs for storage capacity versus data retrieval. AZ-305 candidates must know when to assign blobs to each tier and how to configure lifecycle management policies that automatically transition or delete objects based on last-modified or last-accessed age. Architects are expected to balance total cost of ownership by matching tier selection to data access patterns, such as placing infrequently accessed backups in Cool or Archive while keeping operational data in Hot.
