A company needs to use Amazon S3 to store audio files that are each 5 megabytes in size.The company will rarely access the files, but the company must be able to retrieve the files immediately.
Which S3 storage class will meet these requirements MOST cost-effectively?
S3 Standard
S3 Standard-Infrequent Access (S3 Standard-IA)
S3 Glacier Flexible Retrieval
S3 Glacier Deep Archive
Explanations:
S3 Standard is ideal for frequently accessed data, making it costlier for rarely accessed files.
S3 Standard-IA is designed for infrequent access data, offering lower cost than S3 Standard while still allowing immediate retrieval.
S3 Glacier Flexible Retrieval is suitable for archival data, but retrieval times are slower (minutes to hours), which does not meet the requirement for immediate access.
S3 Glacier Deep Archive is the lowest-cost option for archival data, but retrieval times are longer (12 hours), making it unsuitable for immediate access needs.
I think the answer is:
S3 Standard-Infrequent Access (S3 Standard-IA)
