SAA-C03 Question 542
Single answerYour company has a hybrid cloud architecture. The on-premises data center needs to communicate securely with an Amazon VPC. The data center requires low latency and high bandwidth connectivity for transferring large datasets. Which option would best meet these requirements?
- A
Establish an AWS Direct Connect connection between the data center and the VPC.
- B
Set up a Site-to-Site VPN connection between the data center and the VPC.
- C
Use an internet gateway and transfer data through the public internet.
- D
Deploy an AWS Transit Gateway for secure communication between the data center and the VPC.
Show answer and explanation
Correct answer: A
Explanation
AWS Direct Connect is the best choice for scenarios requiring low latency and high bandwidth connectivity between an on-premises data center and an Amazon VPC. It establishes a private, dedicated connection, bypassing the public internet, which ensures better performance and security. Other options like VPN or internet gateway either lack the necessary performance characteristics or security requirements needed for transferring large datasets efficiently.
- A. Correct.
AWS Direct Connect provides dedicated private connectivity with low latency and high bandwidth, which is ideal for transferring large datasets between an on-premises data center and an Amazon VPC.
- B. Incorrect.
A Site-to-Site VPN connection provides secure connectivity, but it is over the public internet and typically has higher latency and lower throughput compared to AWS Direct Connect.
- C. Incorrect.
Using an internet gateway would allow data transfer over the public internet, which is neither secure nor optimal for low latency or high bandwidth requirements.
- D. Incorrect.
An AWS Transit Gateway facilitates connectivity between multiple VPCs or on-premises networks, but it does not inherently provide a dedicated connection. Additional services like Direct Connect or VPN are required for on-premises connectivity.
