S3 Standard-Ia — AWS Solutions Architect Associate Practice Questions
S3 Standard-IA (Infrequent Access) is a storage class designed for data that is accessed less often but must be retrieved quickly when needed, offering lower storage costs than S3 Standard in exchange for a per-retrieval fee. The AWS Solutions Architect Associate exam tests when Standard-IA is the right choice, typically for backup copies, disaster recovery data, or objects accessed only a few times per month. Key details to know include the 30-day minimum storage duration, the 128 KB minimum object size for billing purposes, and the fact that Standard-IA replicates data across multiple Availability Zones, unlike One Zone-IA. Comparing Standard-IA with other low-cost tiers to select the appropriate class for a given scenario is a common exam question type.
