SAA-C03 Question 459
Single answerA company operates a high-latency, low-bandwidth facility in a remote location where cloud connectivity is unreliable. They need to process data locally and periodically sync it with AWS for long-term storage and analysis. Which solution is the most suitable for their requirements?
- A
Use AWS Outposts to extend AWS infrastructure to the remote facility.
- B
Use AWS Snowball Edge to process data locally and transfer it to AWS when internet connectivity is available.
- C
Launch an EC2 instance in the nearest AWS Region and use a VPN for secure data transfer.
- D
Use Amazon S3 Transfer Acceleration to minimize latency and optimize data transfer.
Show answer and explanation
Correct answer: B
Explanation
AWS Snowball Edge is specifically designed for hybrid environments where internet connectivity is unreliable or unavailable. It enables local data processing and can sync with AWS later, making it the optimal solution for the company's requirements. The other options either depend on stable internet connectivity or do not address the need for local data processing.
- A. Incorrect.
AWS Outposts is ideal for scenarios where you need consistent AWS infrastructure and services on-premises, but it requires reliable connectivity to an AWS Region, which is not suitable for this use case.
- B. Correct.
AWS Snowball Edge is designed for environments with limited to no connectivity. It allows local data processing and can transfer data to AWS once connectivity is available, making it the best choice in this scenario.
- C. Incorrect.
Launching an EC2 instance in the nearest AWS Region requires stable and reliable internet connectivity, which is explicitly stated as unreliable in this use case.
- D. Incorrect.
Amazon S3 Transfer Acceleration helps optimize S3 data transfers over the public internet but still depends on stable internet connectivity, which is not available in this scenario.
