Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 93 discussion

Ans: D The file gateway employs a local read/write cache to provide a low-latency access to data for file share clients in the same local area network (LAN) as the file gateway. Good read - https://d0.awsstatic.com/whitepapers/aws-storage-gateway-file-gateway-for-hybrid-architectures.pdf

On Premise access by admins with low latency means we have to use Storage File Gateway. So option D is my choice.

C. Modify the script to copy data to an Amazon Elastic File System (Amazon EFS) volume instead of the on-premises NFS share. Amazon EFS provides a scalable and highly available file system that can be accessed concurrently from multiple Amazon EC2 instances. It offers low-latency access to files and is suitable for use cases where data needs to be accessed quickly. By migrating the data to Amazon EFS, the company can achieve disaster recovery capabilities in AWS while ensuring that application administrators can access individual backup files with low latency.

I agree, answer is D

D is the answer

I support D. But have one things need to clarify. In the event of disaster we still can connect to Storage Gateway? Please advice .

Answer is D A and B are wrong since the qn is about NFS and S3 is not meant for NFS C is wrong since backup is needed From https://aws.amazon.com/storagegateway/file/: "Nearly all enterprises, regardless of industry, have to store files, whether they are backups, media content, or files generated by specialized industry applications. Managing and scaling on-premises infrastructure to provide online storage and distribution of such backup or content files is often burdensome and costly, requiring expensive hardware refreshes, data center expansion, and software licensing. These large file data repositories can be siloed in specialized file servers, NAS units, or backup systems, limiting access for big data analytics or media processing applications. File Gateway provides a seamless way to connect to the cloud in order to store application data files and backup images as durable objects in Amazon S3 cloud storage. File Gateway offers SMB or NFS-based access to data in Amazon S3 with local caching. It can be used for on-premises applications, and for Amazon EC2-based applications that need file protocol access to S3 object storage."

D for sure since you need storage gateway

it's D

Ans = D

D rigjt

A - Infeasible, Insecure. 1. Since script is made for NFS protocol and S3 do not understand NFS command (cp, mv etc), it would be a complete rewrite. The queston appears to ask to use existing script. 2. Since storage gateway is not mentioned in this option but another one, it implies s3 upload to done via a public endpoint which will unesscery expose the s3 bucket to whole internet. B - Infeasible. Data to Glacier has to go through S3, hence this problem has all the problems of option A and additionally back up files are needed to be accessed in case of failure due to which it don't make sense to archive to glacier. C - Infeasible, Insecure for the same reasons as of option 1. D - correct answer.

D I agree

DDDDDDDDDDDDDDDDDDDDDDDDD

Even I thought it's C.

D is my choice as the applictions on premise shoud be able to access with low latency

D seems great solution. EFS would be a good solution if you were accessing the files from your VPC.
