AWS Certified Solutions Architect – Professional — Question 133

A company has a data center that must be migrated to AWS as quickly as possible. The data center has a 500 Mbps AWS Direct Connect link and a separate, fully available 1 Gbps ISP connection. A Solutions Architect must transfer 20 TB of data from the data center to an Amazon S3 bucket.
What is the FASTEST way transfer the data?

Answer options

• A. Upload the data to the S3 bucket using the existing DX link.
• B. Send the data to AWS using the AWS Import/Export service.
• C. Upload the data using an 80 TB AWS Snowball device.
• D. Upload the data to the S3 bucket using S3 Transfer Acceleration.

Correct answer: D

Explanation

Using S3 Transfer Acceleration (option D) allows for faster uploads by leveraging Amazon CloudFront's globally distributed edge locations, reducing latency. The existing DX link (option A) is slower than the available ISP connection, making it less efficient. The AWS Import/Export service (option B) would not be as rapid as direct uploads, and while the Snowball device (option C) is beneficial for large data transfers, it introduces physical shipping delays that make it slower than using Transfer Acceleration.
