A company needs to store data in an Amazon S3 bucket. The company will rarely access the data and can recreate the data if necessary.Which S3 storage class will meet the requirements for this data MOST cost-effectively?
Answer(s): B
S3 One Zone-Infrequent Access (S3 One Zone-IA) is the most cost-effective storage class for data that is rarely accessed but can be recreated if necessary. This storage class stores data in a single Availability Zone and offers lower costs compared to S3 Standard-IA while still being optimized for infrequent access. However,since the data can be recreated and does not require high availability across multiple Availability Zones, S3One Zone-IA is the best option for cost efficiency.
