This solution meets the requirements most cost-effectively because it enables the company to migrate its on-premises NFS data store to AWS without changing the existing applications or workflows. AWS Storage Gateway is a hybrid cloud storage service that provides seamless and secure integration between on-premises and AWS storage. Amazon S3 File Gateway is a type of AWS Storage Gateway that provides a file interface to Amazon S3, with local caching for low-latency access. By setting up an Amazon S3 File Gateway, the company can store and retrieve files as objects in Amazon S3 using standard file protocols such as NFS.

as their is nfs = file gateway

I'm a little confused by option C & D. How does infrequent access have anything to do with this?

S3 File Gateway => Best for NFS-like file storage workloads

Answer: C

AnswerD Taking into consideration that we are talking about social media company probably storing a lot of quite small files i would say it cannot be Option A or B. For example Amazon S3 File Gateway pricing Storage Pricing Storage Pricing Stored and billed as Amazon S3 objects. Request Pricing Data written to AWS storage by your gateway $0.01 per GB† File storage in S3 Billed as Amazon S3 requests. It can be quite expensive, especially when we will be working on small files. I would go with EFS with OneZone-IA (option D) which should be less expensive taking into consideration that we are paying only for Storage and Data Transfer (per GB). But to be honest we need more information to device which solution will be better.

yeah B

I think B too

B looks correct
