CLF-C02 Question 33
Single answerA company needs to migrate a large on-premises data warehouse containing 80 TB of data to Amazon S3. The company has a slow and unreliable internet connection, which makes transferring data over the network impractical. Which migration strategy is the most appropriate for this scenario?
- A
Upload the data directly to Amazon S3 using the AWS Management Console.
- B
Use AWS Snowball to physically transfer the data to AWS.
- C
Set up AWS Database Migration Service (DMS) to replicate the data.
- D
Use Amazon S3 Transfer Acceleration to speed up the upload process.
Show answer and explanation
Correct answer: B
Explanation
AWS Snowball is the most appropriate migration strategy for transferring 80 TB of data when the network connection is slow and unreliable. Snowball allows the physical transfer of data to AWS, bypassing the limitations of internet-based transfers. Other options, such as direct uploads or S3 Transfer Acceleration, rely on the internet connection and would not be suitable in this case. AWS DMS is not applicable as it is designed for database migrations rather than bulk data transfers.
- A. Incorrect.
Uploading 80 TB of data using the AWS Management Console would be impractical and time-consuming, especially with a slow and unreliable internet connection.
- B. Correct.
AWS Snowball is designed for large data migrations when network transfer is not feasible, making it the most appropriate solution for this scenario.
- C. Incorrect.
AWS Database Migration Service (DMS) is used for database replication, not for migrating large amounts of on-premises data to S3.
- D. Incorrect.
Amazon S3 Transfer Acceleration can speed up uploads, but it still relies on the internet connection, which is slow and unreliable in this scenario.
