Correct answer & explanation
✓
AWS Transfer Family with SFTP endpoint in a VPC
AWS Transfer Family supports SFTP and can be configured with a VPC endpoint to securely transfer data from an FTP server in a private network to S3. Option A is wrong because Kinesis Data Firehose is designed for streaming data ingestion, not for FTP transfers. Option C is wrong because AWS DataSync requires network connectivity to the source, and the FTP server is not internet-accessible. Option D is wrong because AWS Snowball Edge is intended for large-scale offline data transfers, not regular FTP-based transfers.
