SAP-C02 Question 588
Single answerA company wants to migrate 500 TB of data from its on-premises data center to an Amazon S3 bucket. The data transfer must be completed within 3 weeks, and the company has limited outbound internet bandwidth, which would make an online transfer infeasible. Additionally, the data contains sensitive information that must remain secure during transit. Which migration option is the MOST appropriate for this scenario?
- A
Use AWS DataSync to transfer the data over the internet.
- B
Use S3 Transfer Acceleration to speed up the upload process.
- C
Use AWS Snowball Edge to securely transfer the data to Amazon S3.
- D
Use the AWS Transfer Family to establish an SFTP connection for transferring the data.
Show answer and explanation
Correct answer: C
Explanation
Given the constraints of limited outbound internet bandwidth and the need to transfer a large volume of data (500 TB) within a tight timeline, an offline migration method is required. AWS Snowball Edge is specifically designed for secure, large-scale offline data migrations and meets all of the company's requirements, including secure transit and an ability to handle large datasets effectively.
- A. Incorrect.
AWS DataSync is designed for online data migration, but it requires sufficient internet bandwidth to be effective. Given the company's limited outbound internet bandwidth, AWS DataSync is not a feasible option.
- B. Incorrect.
S3 Transfer Acceleration improves transfer speeds over the internet by using Amazon's global edge network, but it still depends on available internet bandwidth. This does not address the company's limited outbound bandwidth constraint.
- C. Correct.
AWS Snowball Edge is a good solution for transferring large amounts of data securely and offline. It is designed for scenarios where internet bandwidth is limited or unavailable, making it the most appropriate choice for this use case.
- D. Incorrect.
The AWS Transfer Family supports protocols like SFTP for transferring data, but it is designed for ongoing data exchange rather than large-scale, one-time migrations. Additionally, it depends on internet connectivity, which is a limiting factor in this scenario.
