Exam Question Walkthrough: Moving 200 TB to AWS
Learn how to tackle an AWS SAA-C03 exam question on moving large data sets efficiently to AWS.
To move large volumes of data to AWS, candidates often struggle with choosing the most cost-effective method. This specific scenario tests your understanding of data transfer solutions under constraints like slow and expensive network links.
The question
To move 200 TB of on-premises data to AWS within days where the network link is slow and expensive, which option is MOST cost-effective?
A. AWS Snowball Edge
B. S3 Transfer Acceleration over the internet
C. AWS Direct Connect provisioned in weeks
D. Upload via the S3 console
Think before you scroll
Consider the size of the data and the limitations of your network. Some options may seem convenient but can be costly or slow when dealing with large transfers.
The answer
The correct option is A. AWS Snowball Edge. This solution is designed for large data transfers, especially when bandwidth is limited. It physically ships the data to AWS, making it faster and more cost-effective than transferring over the network.
Why the other options lose
B. S3 Transfer Acceleration over the internet: While this option speeds up data transfers over the internet, it does not solve the underlying issue of a slow and expensive network link for such a large volume of data. The costs can add up quickly, making it less economical for 200 TB.
C. AWS Direct Connect provisioned in weeks: This option would require a significant time investment to set up. Given the requirement to move data within days, it is not a viable alternative. Additionally, while Direct Connect can lower data transfer costs, the initial setup time makes it impractical for urgent needs.
D. Upload via the S3 console: This option would be the slowest and most expensive choice for transferring 200 TB. Uploading such a large amount of data through the console over a limited bandwidth connection is inefficient and costly.
The concept behind it
Understanding the constraints of network bandwidth and costs is crucial. For large data transfers, using physical devices like AWS Snowball Edge is often the most efficient solution. Always consider the speed and cost implications of each option.
Exam trap to remember
For large data migrations, remember: when bandwidth is a bottleneck, physical transfer is often the best choice.
