Question 880

A company is planning to migrate an application from on premises to the AWS Cloud. The company will begin the migration by moving the application's underlying data storage to AWS. The application data is stored on a shared file system on premises, and the application servers connect to the shared file system through

SMB.

A solutions architect must implement a solution that uses an Amazon S3 bucket for shared storage. Until the application is fully migrated and code is rewritten to use native Amazon S3 APIs, the application must continue to have access to the data through SMB. The solutions architect must migrate the application data to

AWS to its new location while still allowing the on-premises application to access the data.

Which solution will meet these requirements?

    Correct Answer: D

    The correct solution involves creating an S3 bucket and using AWS Storage Gateway (specifically the file gateway) to provide the necessary SMB access from the on-premises environment. This setup allows the application to continue accessing the data through SMB while also storing the data in the S3 bucket. This meets the requirement of having the data stored in Amazon S3 while allowing continued access through SMB until the migration is complete.

Discussion
sb333Option: A

The answer is A. You cannot migrate data to S3 at this time per the question. You must copy the data to AWS to a solution that allows SMB. Later, once they modify the application to use S3, will they then migrate the data to S3. AWS DataSync was built for a solution like this. It can migrate from an on-premises SMB server to FSx for Windows File Server. DataSync will replicate on a schedule and keep the target in sync with the Source based on that replication schedule. https://docs.aws.amazon.com/datasync/latest/userguide/how-datasync-works.html

dcdcdc3Option: D

Since question states that app will be rewritten to use native S3 APIs, I would not pick FSX, rather, use Storage GW/File Gateway and the data will reside in S3. https://stackoverflow.com/questions/71413007/aws-fsx-vs-s3-file-gateway SMB over SGW/FGW is reported way slower than FSX but this is not an issue within the question.

Answer D. SMB it's supported for Storage Gateway to store and retrieve files from S3 bucket: https://aws.amazon.com/about-aws/whats-new/2018/06/aws-storage-gateway-adds-smb-support-to-store-objects-in-amazon-s3/?nc1=h_ls

JohnPiOption: D

File Gateway appliance is a virtual machine to bridge between your NFS and S3

rodrodOption: D

They want to use S3 now but through SMB. Later they will switch to pure S3. Can't be A add it does not support S3...

hobokaboboOption: A

D would work if it weren't windows. It will not really work well. A on the other hand works. Yes we have costs for FX and we need the datasync but it works even with windows.

WhyIronManOption: D

D) must MIGRATE the application data to AWS to its new location WHILE still allowing the on-premises application to access the data

aewisOption: D

The scenario didn't indicate the need of windows integration!

rsnOption: A

Assuming that underlying data on prem will continue to be updated during the migration proccess, "A" works better than "D". Option "D" does not talk about keeping the data in synch

vn_thanhtung

The solutions architect must migrate the application data to AWS to its new location while still allowing the on-premises application to access the data. => D match

JesuisleonOption: D

The question emphasize " the application must continue to have access to the data through SMB", A failed to fulfill this .

Heer

One solution that can meet these requirements is to use Amazon S3 with the AWS Storage Gateway service. AWS Storage Gateway is a hybrid storage service that allows you to store data both on-premises and in the AWS cloud. It provides file-based storage, using the SMB protocol, which is compatible with the on-premises application's existing file access method. The Storage Gateway service can be configured as a File Gateway, which provides a SMB file share that is backed by an Amazon S3 bucket.

Question clearly states "must implement a solution that uses an Amazon S3 bucket for shared storage " so the answer is D

Ell89Option: D

D because if you use Datasync, then you are maintaining two locations and have not actually migrated anything, just replicating. D will allow a migration and permanent switch from on prem to AWS storage.

Ni_yot

Will go with D. B and C ruled out as you need to continue accessing the data during copy. A does migrate date to S3.
