Show answer and explanation
Correct answer: A
Explanation
The company requires a consistent, low-latency, and private connection between its on-premises data center and AWS. AWS Direct Connect is the best solution, as it establishes a dedicated private link without relying on the public internet, ensuring high performance for data transfer.
- A. Correct.
This is the correct answer. AWS Direct Connect provides a dedicated, private network connection between the on-premises data center and AWS, bypassing the public internet for consistent, low-latency performance.
- B. Incorrect.
While a Site-to-Site VPN provides secure connectivity, it uses the public internet, which does not meet the company's requirements for low-latency and consistent performance.
- C. Incorrect.
Elastic Load Balancers are used for distributing traffic to resources within AWS but do not establish a private connection between the on-premises data center and AWS.
- D. Incorrect.
AWS Snowball is a physical data transfer service and is not suitable for establishing ongoing network connectivity between the on-premises data center and AWS.
