AWS Certified Solutions Architect Professional SAP-C02 Practice Question
A life-sciences research group stores 40 TB of genomic sequence files on an on-premises SMB file server. The group must copy the data to an existing Amazon S3 bucket in the same AWS Region and keep the on-premises and cloud copies synchronized every night for the next 30 days while new files are added. Security policy requires that the transfer be encrypted in transit. The network team must restrict the migration traffic to 300 Mbps between 06:00 and 18:00 each business day. The migration team also wants each nightly transfer to automatically validate the integrity of the copied files without writing additional scripts. The solution must introduce the least operational overhead.
Which approach will meet these requirements?
Run a nightly aws s3 sync command from the file server with Amazon S3 Transfer Acceleration enabled, use operating-system traffic-shaping tools to limit bandwidth, and rely on the CLI's --content-md5 option for integrity checks.
Order an AWS Snowball Edge Storage Optimized device, copy the files to the device each evening, ship the device to AWS every week, and use S3 Batch Operations to validate object integrity after import.
Deploy an AWS DataSync agent on-premises, configure the SMB server as the source and the Amazon S3 bucket as the destination, create a task that runs at 02:00 each day with a 300 Mbps bandwidth limit, and rely on DataSync's default TLS encryption and data-verification features.
Create an AWS Transfer Family SFTP endpoint in the VPC and schedule a nightly cron job on the file server that uses the SFTP client to upload files to the endpoint; use command-line options to enforce encryption and checksums.
