For Exam : Whenever you see SFTP , FTP look for "Transfer" in options available

Answer is A AWS Transfer Family securely scales your recurring business-to-business file transfers to AWS Storage services using SFTP, FTPS, FTP, and AS2 protocols. https://aws.amazon.com/aws-transfer-family/

AWS Transfer Family is for FTP,SFTP,FTPS

Option A is the most suitable choice for implementing a highly available SFTP solution with minimal operational overhead in this scenario

The key advantages of AWS Transfer Family are: It provides a fully managed file transfer service that eliminates the need to manage your own file transfer infrastructure. This reduces operational overhead. It supports multiple protocols like SFTP, FTPS, FTP and AS2, allowing easy and secure exchange of data with business partners and customers. File transfers happen directly into Amazon S3 buckets or Amazon EFS file systems, so the transferred data can be easily accessed by other AWS services for analytics, processing etc. AWS Transfer Family maintains existing client-side configurations, so file transfer workflows remain unchanged for end users and partners. It provides high availability and auto-scaling capabilities to handle varying transfer workloads.

Amazon S3 File Gateway, involves deploying an on-premises gateway that interfaces with S3. While it’s a valid solution, it introduces a level of on-premises infrastructure that may require more operational management.

AWS Transfer Family securely scales your recurring business-to-business file transfers to AWS Storage services using SFTP, FTPS, FTP, and AS2 protocols.

A is the correct answer. AWS Transfer Family provides a fully managed SFTP service that can integrate directly with S3. It handles scaling, availability, and security automatically with minimal overhead.

AWS Transfer Family is a fully managed service that makes it easy to set up and manage secure file transfers. It provides a high-availability SFTP server that can be accessed from the public internet. However, this solution does not minimize operational overhead, as it requires the solutions architect to manage the SFTP server.

This solution provides a highly available SFTP solution without the need for manual management or operational overhead. AWS Transfer Family allows you to easily set up an SFTP server with authentication, authorization, and integration with S3 as the storage backend. Option B is not the best choice as it suggests using Amazon S3 File Gateway, which is primarily used for file-based access to S3 storage over NFS or SMB protocols, not for SFTP access. Option C is not the best choice as it requires manual management of an EC2 instance, VPN setup, and cron job script for uploading files, introducing operational overhead and potential complexity. Option D is not the best choice as it also requires manual management of EC2 instances, Network Load Balancer, and cron job scripts for file uploads. It is more complex and involves additional components compared to the simpler and fully managed solution provided by AWS Transfer Family in option A.

I can't wrap my head around why the answer is D? this is so frustrating to see where i went wrong. I vote for A.

minimizes operational overhead = Serverless AWS Transfer Family is serverless

AWS Transfer Family is compatible for SFTP<FTPS<FTP. A is the answer

AWS Transfer Family is a fully managed AWS service that you can use to transfer files into and out of Amazon Simple Storage Service (Amazon S3) storage or Amazon Elastic File System (Amazon EFS) file systems over the following protocols: Secure Shell (SSH) File Transfer Protocol (SFTP): version 3 File Transfer Protocol Secure (FTPS) File Transfer Protocol (FTP) Applicability Statement 2 (AS2)

A - is the correct answer.

A -- is the option
