Question #: 547
Topic #: 1

[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A solutions architect is designing the cloud architecture for a new application that is being deployed on AWS. The application's users will interactively download and upload files. Files that are more than 90 days old will be accessed less frequently than newer files, but all files need to be instantly available. The solutions architect must ensure that the application can scale to store petabytes of data with maximum durability.
Which solution meets these requirements?

A. Store the files in Amazon S3 Standard. Create an S3 Lifecycle policy that moves objects that are more than 90 days old to S3 Glacier.
B. Store the files in Amazon S3 Standard. Create an S3 Lifecycle policy that moves objects that are more than 90 days old to S3 Standard-Infrequent Access (S3 Standard-IA).
C. Store the files in Amazon Elastic Block Store (Amazon EBS) volumes. Schedule snapshots of the volumes. Use the snapshots to archive data that is more than 90 days old.
D. Store the files in RAID-striped Amazon Elastic Block Store (Amazon EBS) volumes. Schedule snapshots of the volumes. Use the snapshots to archive data that is more than 90 days old.

For A: S3 Standard-IA is for data that is accessed less frequently, but requires rapid access when needed. S3 Standard-IA offers the high durability, high throughput, and low latency of S3 Standard, with a low per GB storage price and per GB retrieval charge

For A: 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. Confused which is better in this quesiton ?

Exactly, why not A since Glacier has instant retrieval feature? I would go with A

No, don't provide wrong info. 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.

Take your own advice, Glacier Instant Retrieval is not the same as Flexible Retrieval and it offers instantaneous retrieval. "S3 Glacier Instant Retrieval delivers the fastest access to archive storage, with the same throughput and milliseconds access as the S3 Standard and S3 Standard-IA storage classes." https://aws.amazon.com/s3/storage-classes/glacier/instant-retrieval/
