D. S3 One Zone-Infrequent Access (S3 One Zone-IA) For a scenario where data is rarely accessed, and the company can regenerate the data if needed, the most cost-effective storage class would be S3 One Zone-Infrequent Access (S3 One Zone-IA). This storage class stores data in a single availability zone, providing cost savings compared to storage classes that store data redundantly across multiple availability zones.

S3 One Zone-IA is ideal for customers who want a lower-cost option for infrequently accessed

D. S3 One Zone-Infrequent Access (S3 One Zone-IA) - most cost effective solution that is ideal for data that can be easily recreated and not critical if lost.

It simply reads what cost-effective storage class you should choose for rarely accessed data that can be regenerated. That would be D). S3 One Zone-Infrequent Access (S3 One Zone-IA) Why not S3 Standard-IA? S3 Standard-IA is durable, immediately available, and infrequently accessed, while S3 One Zone-IA has a lower cost, is infrequently accessed, and is less resilient.

Since the company rarely accesses the data and can regenerate it if needed, S3 One Zone-IA offers a balance of cost savings and availability for their use case.

S3 One Zone-Infrequent Access (S3 One Zone-IA) is the most cost-effective storage class.

For other infrequently accessed data, such as duplicates of backups or data summaries that can be regenerated, S3 One Zone-IA provides a lower price point. Reference: https://aws.amazon.com/about-aws/whats-new/2018/04/announcing-s3-one-zone-infrequent-access-a-new-amazon-s3-storage-class/

S3 Standard-IA is designed for infrequently accessed data but still provides low-latency and high-throughput performance when needed. It is a cost-effective option compared to S3 Standard, which is designed for frequently accessed data. With S3 Standard-IA, you pay a lower storage fee, but there is a retrieval fee when accessing the data.

S3 Standard-Infrequent Access (S3 Standard-IA)

S3 Standard-IA is ideal for infrequently accessed data. It also has a lower storage price and higher retrieval price. Reference: AWS Skill Builder.
