Topic 1 Question 918
A company is using AWS DataSync to migrate millions of files from an on-premises system to AWS. The files are 10 KB in size on average.
The company wants to use Amazon S3 for file storage. For the first year after the migration, the files will be accessed once or twice and must be immediately available. After 1 year, the files must be archived for at least 7 years.
Which solution will meet these requirements MOST cost-effectively?
Use an archive tool to group the files into large objects. Use DataSync to migrate the objects. Store the objects in S3 Glacier Instant Retrieval for the first year. Use a lifecycle configuration to transition the files to S3 Glacier Deep Archive after 1 year with a retention period of 7 years.
Use an archive tool to group the files into large objects. Use DataSync to copy the objects to S3 Standard-Infrequent Access (S3 Standard-IA). Use a lifecycle configuration to transition the files to S3 Glacier Instant Retrieval after 1 year with a retention period of 7 years.
Configure the destination storage class for the files as S3 Glacier Instant Retrieval. Use a lifecycle policy to transition the files to S3 Glacier Flexible Retrieval after 1 year with a retention period of 7 years.
Configure a DataSync task to transfer the files to S3 Standard-Infrequent Access (S3 Standard-IA). Use a lifecycle configuration to transition the files to S3 Deep Archive after 1 year with a retention period of 7 years.

D simplifies the process by directly using S3 Standard-IA and then transitioning to S3 Glacier Deep Archive, which aligns well with access patterns and cost requirements. Option A sounds right but using an archive tool to group files into large objects adds complexity and operational overhead. This step isn’t necessary if you can directly manage the files with S3 lifecycle policies.

Its A, took some research but A is correct Per Amazon S# glacier page: "Amazon S3 Glacier Instant Retrieval is an archive storage class that delivers the lowest-cost storage for long-lived data that is rarely accessed and requires retrieval in milliseconds. With S3 Glacier Instant Retrieval, you can save up to 68% on storage costs compared to using the S3 Standard-Infrequent Access (S3 Standard-IA) storage class, when your data is accessed once per quarter." After the one year move it to Deep archive.

D is most cost effective
