Which S3 storage option stores data in a single availability zone to reduce costs?

• A. S3 One Zone-IA
• B. S3 Cross-Region Replication
• C. S3 Standard-IA
• D. S3 Glacier

Answer: (A)

S3 One Zone-IA (Infrequent Access) is specifically designed to store data in a single availability zone, which allows for a cost-effective storage solution for infrequently accessed data. This option is ideal for data that does not need the resilience provided by storing it across multiple availability zones, thus significantly reducing storage costs compared to other options. This storage class is particularly beneficial for customers who can tolerate some risk of data loss, as One Zone-IA does not replicate the data across multiple locations. Consequently, it offers lower prices, making it an ideal choice for scenarios where data retrieval is infrequent and where the associated costs of multi-zone redundancy are unnecessary. In contrast, other options such as S3 Cross-Region Replication and S3 Standard-IA involve multiple availability zones, providing higher durability and availability but at a higher cost. S3 Glacier is primarily aimed at long-term archival storage and retrieval, typically involving longer retrieval times and a different pricing structure based on access frequency and retrieval needs. Thus, S3 One Zone-IA is the most cost-effective choice for infrequently accessed data stored in a single availability zone.
