Question 1

You are in charge of the backup processes for converting an in-house network storage system to S3 on AWS. You want to minimize the costs of cloud storage but preserve the lowest possible latency for requests to the cloud-hosted files. What storage class would you suggest?
A. S3 standard
B. S3-IA
C. S3 One Zone-IA
D. Glacier

Answer 1

Here, the determining factor is the requirement of instant access. S3 One Zone-IA will give you that access, at a lower cost than S3 standard and S3-IA. According to AWS, all three classes have the same first byte latency (milliseconds).
