SAP-C02 Question 586
Single answerA company is planning to migrate a large dataset (50 TB) from its on-premises storage to Amazon S3. The data needs to be transferred securely and efficiently, and the company wants to minimize migration time. Due to limited internet connectivity at the on-premises location, the company is seeking an alternative method to transfer the data. Which AWS service or feature should the company use to meet these requirements?
- A
AWS DataSync
- B
AWS Snowball
- C
Amazon S3 Transfer Acceleration
- D
AWS Transfer Family
Show answer and explanation
Correct answer: B
Explanation
AWS Snowball is the best solution for this scenario as it allows for the secure and efficient transfer of large datasets (50 TB) without relying on internet connectivity. The company can use Snowball devices to physically transfer the data to AWS. Other options, such as AWS DataSync and S3 Transfer Acceleration, depend on internet bandwidth, making them unsuitable given the company's limited connectivity.
- A. Incorrect.
AWS DataSync is a good solution for transferring data securely and efficiently between on-premises storage and AWS, but it relies on internet connectivity, which is limited in this scenario.
- B. Correct.
AWS Snowball is designed for offline, large-scale data migrations. It is an ideal choice for transferring large datasets (like 50 TB) when internet connectivity is insufficient.
- C. Incorrect.
Amazon S3 Transfer Acceleration is useful for speeding up S3 uploads over the internet, but it still requires sufficient internet bandwidth to be effective, which is not available in this case.
- D. Incorrect.
AWS Transfer Family is primarily used for transferring files over SFTP, FTPS, and FTP connections. It is not suitable for bulk data migrations involving limited internet connectivity.
