SAA-C03 Question 353
Single answerA company needs to migrate 80 TB of on-premises data to Amazon S3. The data transfer must minimize downtime and ensure efficient handling of the large dataset. The company also wants the solution to be suitable for ongoing data transfers in the future. Which AWS service best meets this requirement?
- A
AWS DataSync
- B
AWS Storage Gateway - File Gateway
- C
AWS Snowball
- D
AWS Direct Connect
Show answer and explanation
Correct answer: A
Explanation
AWS DataSync is the best solution for this scenario because it efficiently handles large-scale, one-time migrations as well as ongoing transfers. While AWS Snowball can handle large data migrations, it is not ideal for ongoing data transfers. AWS Storage Gateway is more suited for hybrid storage use cases, and AWS Direct Connect is not a data transfer service.
- A. Correct.
AWS DataSync is designed for large-scale data transfers to AWS services such as S3, EFS, and FSx. It is highly efficient, minimizes downtime, and supports both one-time migrations and ongoing data transfers.
- B. Incorrect.
AWS Storage Gateway - File Gateway is primarily used for hybrid storage solutions where frequently accessed data is cached locally, and data is asynchronously uploaded to AWS. It is not optimized for bulk data migrations.
- C. Incorrect.
AWS Snowball is suitable for large-scale data migrations but is better suited for environments where network connectivity is limited or unreliable. It does not support ongoing data transfer as effectively as AWS DataSync.
- D. Incorrect.
AWS Direct Connect establishes a dedicated network connection between an on-premises data center and AWS but is not a service specifically designed for data transfer. It is more suitable for low-latency, high-bandwidth applications.
