A company stores a large volume of image files in an Amazon S3 bucket. Images must be readily available for the first 180 days, infrequently accessed for the next 180 days, then archived after 360 days but available instantly upon request. After 5 years, only auditors can access the images, and auditors must retrieve them within 12 hours. Objects cannot be lost during this process. A developer uses S3 Standard for the first 180 days and needs to create an S3 Lifecycle rule. Which configuration is the MOST cost-effective while meeting these requirements?

The correct option uses S3 Standard-IA for infrequently accessed data that requires high durability and multiple Availability Zones, which is a better fit than S3 One Zone-IA for critical data. S3 Glacier Instant Retrieval meets the requirement for instant availability after 360 days, offering millisecond retrieval times. Finally, S3 Glacier Deep Archive is the most cost-effective solution for long-term archiving (after 5 years) where retrieval within 12 hours is acceptable, as specified for auditors. Incorrect options: Using S3 One Zone-IA introduces a risk of data loss if the single Availability Zone fails, which violates the "objects cannot be lost" requirement. S3 Glacier Flexible Retrieval (formerly S3 Glacier) has retrieval times ranging from minutes to hours, which does not meet the "instantly upon request" requirement after 360 days.
