ANS-C01 Question 404
Select 2Your company needs to transfer a large amount of data between an on-premises data center and an Amazon VPC. The connection must be cost-effective while maintaining consistent performance. Which of the following options would you consider? (Choose TWO)
- A
AWS Direct Connect with a 1 Gbps connection
- B
AWS Site-to-Site VPN over the internet
- C
Using AWS Snowball Edge for initial data transfer and Site-to-Site VPN for ongoing synchronization
- D
Using an internet gateway and Elastic IPs for data transfer
- E
AWS Transit Gateway with Direct Connect Gateway
Show answer and explanation
Correct answers: A, C
Explanation
For cost-effective connectivity between a VPC and an on-premises environment, AWS Direct Connect provides a dedicated connection with consistent performance and avoids high internet bandwidth costs. For initial large data transfers, AWS Snowball Edge is highly cost-effective, and pairing it with Site-to-Site VPN for ongoing synchronization ensures efficiency while keeping costs low.
- A. Correct.
AWS Direct Connect with a 1 Gbps connection provides dedicated, consistent bandwidth between on-premises and AWS. It's cost-effective for large data transfers because you avoid internet bandwidth charges and gain consistent performance.
- B. Incorrect.
AWS Site-to-Site VPN over the internet is a viable option for secure connectivity, but it is not cost-effective for ongoing large data transfers due to potential internet bandwidth costs and inconsistent performance.
- C. Correct.
Using AWS Snowball Edge for the initial data transfer reduces the costs and time for transferring large datasets. Combining it with Site-to-Site VPN for ongoing synchronization can be a cost-effective and efficient solution.
- D. Incorrect.
Using an internet gateway and Elastic IPs for data transfer is not a recommended solution for large data movement due to high data transfer costs and lack of consistent performance.
- E. Incorrect.
AWS Transit Gateway with Direct Connect Gateway is a scalable solution, but it is more suitable for complex multi-VPC and multi-region architectures rather than cost-effective direct connectivity for large data transfers.
