I support answer A. if the data transfer would take more than a week then it is more efficient to use Snowball (for 70TB). The 150MB, with full speed (using the maximum Acceleration on the world) requires around ~43 days 5 hours 2 minutes to transfer the 70TB to AWS. Then this is a waste of time, resources, and could be more expensive than snowball (taking into consideration that the 10 people can not use the 150MB as it is busy uploading). Storage gateway, is not meant for such a single time archiving. direct connect, is too expensive for such one time job. So, definitely the answer is "A".

Good explanation Moon. The good hint is "taking into consideration that the 10 people can not use the 150MB as it is busy uploading)". I vote for A

Ans a perfectly matches. Snowballs come in two sizes: 50 TB and 80 TB. and provides most efficient way than s3 acceleration..

Selected Answer: A
AWS Snowball is a service specifically designed for large-scale data transfers. It provides a physical device called a Snowball appliance that you can use to securely transfer data to and from Amazon S3. Snowball appliances come in different sizes, and they are shipped to your location, allowing you to transfer data offline and then ship the appliance back to AWS for data ingestion.

A is the correct answer, key term is efficient way. 100 terabytes of data will take more than 100 days to transfer over a dedicated 100 Mbps connection. A is efficient because we will use only one snowball device (80TB) in less than week

https://aws.amazon.com/s3/faqs/ S3 Transfer Acceleration is designed to optimize transfer speeds from across the world into S3 buckets. If you are uploading to a centralized bucket from geographically dispersed locations, or if you regularly transfer GBs or TBs of data across continents, you may save hours or days of data transfer time with S3 Transfer Acceleration.
