CLF-C02 Question 138
Single answerA company is migrating its data to Amazon S3 for the first time. The migration involves transferring 5 TB of data from an on-premises data center. The company expects this to be a one-time operation and does not anticipate similar migrations in the future. Which of the following is the most suitable solution for this scenario?
- A
Use AWS Snowball to transfer the data to Amazon S3
- B
Set up AWS DataSync for continuous data transfer
- C
Manually upload the data using the S3 Management Console
- D
Use an S3 Transfer Acceleration endpoint for faster uploads
Show answer and explanation
Correct answer: A
Explanation
For a one-time data transfer of 5 TB, AWS Snowball is the most suitable choice as it provides a physical device to transfer data securely and efficiently. Other options like AWS DataSync are better suited for repeatable transfers, while manual uploads and S3 Transfer Acceleration are impractical for this scale.
- A. Correct.
AWS Snowball is a cost-effective and efficient solution for one-time large data migrations, especially for datasets as large as 5 TB. It avoids reliance on internet bandwidth and is ideal for this scenario.
- B. Incorrect.
AWS DataSync is designed for ongoing or repeatable data transfers. It is not cost-effective or necessary for a one-time operation.
- C. Incorrect.
Manually uploading 5 TB of data using the S3 Management Console is impractical and time-consuming for such a large dataset.
- D. Incorrect.
S3 Transfer Acceleration is intended to speed up internet-based uploads but is not optimal for transferring 5 TB of data, especially if the internet connection is slow or unreliable.
