AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question
An operations team must migrate 500 TB of data from an on-premises NFS file server to an Amazon S3 bucket in us-east-1 within seven days. The site has a dedicated, mostly idle 10 Gbps AWS Direct Connect link. The team wants the simplest AWS DataSync configuration that can saturate the link during the bulk copy and then be reused for scheduled incremental syncs after the cut-over. What should the team do?
Use the AWS CLI with aws s3 sync for the full copy, and reserve DataSync only for incremental syncs.
Deploy a single DataSync agent on-premises, create one DataSync task that copies the entire share to the bucket, and leave the task bandwidth setting at "Use available".
Deploy two DataSync agents and create two separate tasks, each copying half of the directory tree to different prefixes in the bucket.
Deploy two DataSync agents and assign both agents to the same task so the task can reach 20 Gbps.
A single DataSync task can use up to 10 Gbps, which is approximately 1.25 GB/s or about 108 TB per day in ideal conditions. Even allowing for protocol overhead, a single agent running at roughly 70 TB per day can move 500 TB in seven days (7 × 70 ≈ 490 TB). Therefore, deploying one on-premises agent and configuring the task to use all available bandwidth is sufficient to meet the timeline while keeping the setup simple. DataSync automatically tracks metadata and can be re-run on a schedule for incremental copies. Adding extra agents or splitting the dataset adds complexity without bypassing the 10 Gbps per-task limit, and S3 Transfer Acceleration is not used by DataSync.
