Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 364 discussion

B is the right choice.

Answer: B before 30 days = Frequent -> S3 After 30 days = 5minutes -> S3G-EXP (1-5Minutes) Previous Objects = 1 week -> S3G-DA standard (12hours) Am I wrong?

C is the best solution as it moves current object versions to S3 Standard-IA, which provides a low-cost storage option for infrequently accessed data, and previous object versions to S3 Glacier Deep Archive, which is the most cost-effective storage option for long-term archival.The question is about cost effectiveness and B will be more costly than C

B is correct. We can use Glacier Expedited retrieval which takes 1-5 minutes to load the required data and for the previous data, Glacier Deep Archive should be good as it takes up to 12 Hours for the required data to be loaded which is more than enough as compared to a week

B is the answer

"Expedited retrievals allow you to quickly access your data that's stored in the S3 Glacier Flexible Retrieval storage class or the S3 Intelligent-Tiering Archive Access tier when occasional urgent requests for a subset of archives are required. "https://docs.aws.amazon.com/AmazonS3/latest/userguide/restoring-objects-retrieval-options.html#:~:text=To%20make%20an%20Expedited%2C%20Standard%2C%20or%20Bulk%20retrieval%2C,are%20automatically%20served%20%20through%20your%20provisioned%20capacity."

Option B: Glacier [expedite retrieval] < 5 min and Glazier deep archive < 48 hours

in Option B, The lifecycle policy for s3 to Glacier would only work after 90 days, right?

why B? it says "For all but the largest archives (250 MB+), data accessed using Expedited retrievals are typically made available within 1–5 minutes." What about files over 250MB, there's no way to get them in 5min. C is right

According to this resource: The Amazon S3 Glacier storage class provides three retrieval options to fit your use case. Expedited retrievals typically return data in 1-5 minutes, and are great for Active Archive use cases. Standard retrievals typically complete between 3-5 hours, and are best suited for less time-sensitive needs like backup data, media editing, or long-term analytics. Bulk retrievals are the lowest-cost retrieval option, returning large amounts of data within 5-12 hours. The Amazon S3 Glacier Deep Archive storage class provides two retrieval options ranging from 12-48 hours. Looking at the pricing from this resource: https://aws.amazon.com/s3/pricing/?nc=sn&loc=4 Is S3 One Zone - Infrequent Access* not a cheaper option than Glacier, as with Glacier each time the customer needs a restore it needs to be expiated ($11.00 per 1000 requests or $0.033 per GB) where as S3 1 Zone IA is cheaper per GB

Both B and C are correct, but the question is which one is the most cost-effective My take is B

Please someone calculate the ratio of S3 Glacier experdated retrieval fee and S3 Standard-IA fee.

Answer is B S3G can be configured to retrieve from minutes to hours. This is definitely cost-effective than S3 IA

To those who say that B is correct because of Expedited Retrieval Option, what is if object is larger than 250mb? Expedited — Expedited retrievals allow you to quickly access your data when occasional urgent requests for a subset of archives are required. For all but the largest archives (250 MB+), data accessed using Expedited retrievals are typically made available within 1–5 minutes. Provisioned Capacity ensures that retrieval capacity for Expedited retrievals is available when you need it. For more information, see Provisioned Capacity.

C. glacier has minimum storage of 90 days duration charge .

B is correct. We can use Glacier Expedited retrieval which takes 1-5 minutes to load the required data and for the previous data, Glacier Deep Archive should be good as it takes up to 12 Hours for the required data to be loaded which is more than enough as compared to a week

Never mind, I'm with B... missed the one-week part. I need to READ.
