Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 420 discussion

D - storage gateway. My take: D - The files will be on the storgare gateway with low latency and copied to AWS as a second copy. FSx in AWS will not provide low latency for the on prem apps over a vpn to the FSx file system.

D. AWS Storage Gateway

D is the answer

SMB is the keyword

The question is asking for a service which enables the organization to transfer files to AWS. FSX is a file sharing service, so the transferred files might end up in FSX, but it is not the service for transferring files. Since it is mentioned that we need a service for transferring SMB files, the exact answer would be File Gateway, which is a type of Storage Gateway. So, D is the correct answer.

Are these questions useful in August 2022?

D - "lacks the time required to modify the application's code" - "migrate it to AWS" - "transfer files to Amazon Web Services"

For transferring files (which has been asked in the question) >> ans is D

- FSx for Windows File Server and Storage Gateway (FSx File Gateway) are valid options, and both support the SMB protocol - Questions asks for "file transfer", which Storage Gateway is better for - FSx is more of "file system in the cloud", which may require application-level code changes, as the local and remote file servers do not automatically sync like FQW does

There is no mention about Windows OS - given that and they need to migrate the files over to AWS, it would be storage gateway

D: SGW need vpn connection http://blog.centrestack.com/2020/12/problems-with-vpn-based-access-to-file.html

The fact that it says SMB it doesn’t mean it’s a Windows Machine. As far as I know SMB can be used also on Linux and Mac so FSX may not be the right solution if the OS is not Windows. Also, they already have data on a storage so what is needed is to use Storage Gateway to sync that on-premise content to AWS. D is my take.

Both B and D seems to be correct and will work For support of D: AWS Storage Gateway is a hybrid cloud storage service that gives you on-premises access to virtually unlimited cloud storage. Storage Gateway provides a standard set of storage protocols such as iSCSI, SMB, and NFS, which allow you to use AWS storage without rewriting your existing applications. It provides low-latency performance by caching frequently accessed data on premises, while storing data securely and durably in Amazon cloud storage services. Storage Gateway optimizes data transfer to AWS by sending only changed data and compressing data. Storage Gateway also integrates natively with Amazon S3 and Amazon FSx for Windows File Server cloud storage which makes your data available for in-cloud processing, For support of B https://aws.amazon.com/blogs/storage/accessing-smb-file-shares-remotely-with-amazon-fsx-for-windows-file-server/ Not sure which one to pick

D - after going through https://aws.amazon.com/about-aws/whats-new/2018/06/aws-storage-gateway-adds-smb-support-to-store-objects-in-amazon-s3/

I believe the answer here is B. Because of this link. https://aws.amazon.com/fsx/windows/faqs/ Q: How does Amazon FSx support access from my on-premises environment? A: Yes, you can access Amazon FSx file systems from your on-premises environment using an AWS Direct Connect or AWS VPN connection between your on-premises datacenter and your Amazon VPC. With support for AWS Direct Connect, Amazon FSx allows you to access your file system over a dedicated network connection from your on-premises environment. With support for AWS VPN, Amazon FSx allows you to access your file system from your on-premises devices over a secure and private tunnel. Why setting up an AWS storage gateway when you can do the job with what you have (VPN). In addition, the question mentions that “The application development team does not have time to make the necessary code modifications to move the application to AWS.”

D - - Storage Gateway enables you to reduce your on-premises storage footprint and associated costs by leveraging AWS cloud storage services. - The Amazon S3 File Gateway enables you to store and retrieve objects in Amazon S3 using file protocols such as Network File System (NFS) and Server Message Block (SMB). Objects written through S3 File Gateway can be directly accessed in S3.

For on-premise Storage Gateway is required. The answer should be "D". But FSx also have FSx file gateway this may be use for this scenario https://aws.amazon.com/storagegateway/file/fsx/ The answer would be B or D ... , Problem is B is not talking about FSx file gateway. So, B is not the answer. I select D - Storage Gateway
