AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

AWS DataSync is a managed data-transfer service that automatically performs highly parallel, multipart uploads with inline compression. One task can saturate a 10 Gbps link, so copying 6 TB can finish in roughly 2 hours instead of 14, without tuning the EC2 host. Creating an agent VM and a scheduled task takes only minutes and requires no code maintenance, so operational overhead remains low.

S3 Transfer Acceleration optimizes internet paths and provides little or no benefit when traffic already flows over a private Direct Connect circuit. Rewriting the script to use the AWS SDK Transfer Manager, or merely increasing the AWS CLI s3.max_concurrent_requests setting, could improve performance but still relies on the EC2 host and requires script or configuration changes. Neither is likely to match DataSync's throughput or ease of use.
