A sure, you can use Expedited retrievals to access data in 1 – 5 minutes for a flat rate of $0.03 per GB retrieved. Expedited retrievals allow you to quickly access your data when occasional urgent requests for a subset of archives are required

Answer is A, S3 Glacier as that is the cheapest option and also satisfies the retrieval requirement S3 One Zone - Infrequent Access * - For re-createable infrequently accessed data that needs millisecond access All Storage / Month $0.01 per GB S3 Glacier ** - For long-term backups and archives with retrieval option from 1 minute to 12 hours All Storage / Month $0.004 per GB S3 One Zone - Infrequent Access * - For re-createable infrequently accessed data that needs millisecond access All Storage / Month $0.01 per GB S3 Glacier ** - For long-term backups and archives with retrieval option from 1 minute to 12 hours All Storage / Month $0.004 per GB

NOT A - What is the MOST cost-effective solution? Expedited retrievals are the fastest option, but they are also the most expensive, costing $0.03 per GB and $0.01 per request

C is the answer, this is due to the fact that the question states what is the most cost-effective. In this scenario if you calculate the costs of storing and including retrievals C is the most cost-effective solution

S3 One zone is much cheaper option

A sure

Expedited – 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. For all but the largest archives (more than 250 MB), data accessed by using Expedited retrievals is typically made available within 1–5 minutes. https://docs.aws.amazon.com/amazonglacier/latest/dev/downloading-an-archive-two-steps.html

A for several reasons: - key term archive - Glacier is the cheapest. - Expedited retrievals give access to date in 1-5 minutes (as it is a rare case it is the best balance)

A is the best answer as Glacier Archive is cheaper than S3 IA + Expedited retrievals will help for quick access

seldom need to recover these data. When files are required, they must be provided within a five-minute window... Glacier is cheapest option with expedited retrieval within ti 5 min window

Why D? it is Archival data and Glacier ER will get his under 5 mins.

This is NOT A: For all but the largest archives (250 MB+), data accessed using Expedited retrievals are typically made available within 1–5 minutes. Do you think your video archives are under 250 MB?

Glacier has several options. there are expedited, standard, bulk options. expedited 1~5 minutes, standard 3~5 hours, bulk 5~12 hours is expected. And Glacier is cheapest class.

Answer A. Please note that question doesn't mention size of data. If it would then the answer may be different
