🎯 How does AWS Transfer Family appear on the SAA-C03 Exam?
You may be asked to design a solution for a third-party vendor who requires SFTP access to upload reports directly into an S3 bucket.
A scenario might describe a requirement to migrate a legacy on-premises FTP server to AWS while minimizing administrative overhead and ensuring high availability.
Expect questions where you must choose between hosting an SFTP server on EC2 versus using AWS Transfer Family based on operational efficiency.
❓ Frequently Asked Questions
Can AWS Transfer Family be used with Amazon EFS?
Yes, it supports both S3 and EFS. EFS is ideal for workloads requiring a POSIX-compliant file system or shared access across multiple EC2 instances.
How does this service handle user authentication for thousands of external clients?
For large-scale deployments, use a custom identity provider. By integrating AWS Lambda and API Gateway, you can authenticate users against an existing corporate database.
