A media company uploads 50 GB video files from multiple on-premises locations worldwide to an S3 bucket in us-west-2. The uploads are time-sensitive and must complete within 30 minutes. The company's internet connections vary from 100 Mbps to 1 Gbps. The company has already enabled S3 Transfer Acceleration, but uploads from some locations are still slow. What should the company do to further improve upload performance?

Create an S3 bucket in each on-premises region and use S3 Cross-Region Replication to copy the files to us-west-2.

Use AWS DataSync to transfer the files from each on-premises location to the S3 bucket.

Use AWS Snowball Edge to physically ship the data to AWS.

Use multipart upload with a part size of 100 MB and upload parts in parallel from each location.

What is the purpose of an EFS lifecycle policy?

To automatically increase the provisioned throughput of the file system

To encrypt files at rest using AWS KMS

To automatically transition files to the Infrequent Access storage class after a specified period

To replicate files to another region for disaster recovery
