A Glacier Deep Archive retrieval time more than 5 hours (it's 12 hours), so B&D out. S3 Standard IA is cheaper than S3 Standard. https://aws.amazon.com/tw/s3/pricing/

S3 Glacier Flexible Retrieval provides three retrieval options: expedited retrievals that typically complete in 1–5 minutes, standard retrievals that typically complete in 3–5 hours, and free bulk retrievals that return large amounts of data typically in 5–12 hours. The Amazon S3 Glacier Deep Archive storage class provides two retrieval options ranging from 12-48 hours.

S3 Standard is almost double the price of S3 Standard - Infrequent Access https://aws.amazon.com/s3/pricing/?p=pm&c=s3&z=4

Answer is C

A. why? For the first 90 days it wont be frequently accessed, but when it does, needs to be retrieved in milliseconds. Both A and B would cover this, but it also mentions "highly available" which would exclude the one zone option. I see many people justifying A because of the glacier tier, which in the case for cost savings should be deep archive, like B. There is no mention that after 90 days the retrieval needs to be in milliseconds and deep archive is cheaper (75% cheaper) the perfect answer would be infrequent access and deep archive. So A because one-zone kills the HA requirement for the first 90 days.

The answer is A

AAAAAAAAAAA

It's A. The question says that the data will be infrequently accessed. Also, A it's cheaper than C.

Ans is C
