A solutions architect designs storage in Amazon S3 for a digital media application. Objects must be resilient to the loss of an Availability Zone. Some files are accessed frequently, others are rarely accessed with an unpredictable pattern. The architect must minimize storage and retrieval costs. Which S3 storage option meets these requirements?

S3 Intelligent-Tiering is the correct choice because it automatically moves objects between two access tiers (frequently accessed and infrequently accessed) based on access patterns. This optimizes storage costs without performance impact and is designed for resilience across multiple Availability Zones. S3 Standard is highly available but does not optimize for varying access patterns, leading to higher costs for infrequently accessed data. S3 Standard-IA is cost-effective for infrequently accessed data but charges retrieval fees, and its fixed tiering doesn't suit unpredictable access. S3 One Zone-IA is the cheapest option for infrequent access but is not resilient to the loss of an Availability Zone, failing a key requirement.
