Amazon ANS-C01 Exam - Topic 4 Question 68 Discussion

A company has multiple AWS Site-to-Site VPN connections between an on-premises environment and multiple VPCs. The Site-to-Site VPN connections use virtual private gateways and are configured with IPv4 addresses. The company hosts several internal applications in the VPCs.Application users have reported that the applications are performing slowly. A network engineer notices excessive latency in the network path that the VPN connections use. The network engineer needs to resolve the excessive latency.Which solution will meet this requirement?
B) Deploy a transit gateway and a new accelerated Site-to-Site VPN connection.
A) Use AWS Global Accelerator to deploy an accelerator on the existing Site-to-Site VPN connections.
C) Replace the existing Site-to-Site VPN connections with new Site-to-Site VPN connections that use IPv6.
D) Replace the existing Site-to-Site VPN connections with AWS PrivateLink connections.

A company has multiple AWS Site-to-Site VPN connections between an on-premises environment and multiple VPCs. The Site-to-Site VPN connections use virtual private gateways and are configured with IPv4 addresses. The company hosts several internal applications in the VPCs.

Application users have reported that the applications are performing slowly. A network engineer notices excessive latency in the network path that the VPN connections use. The network engineer needs to resolve the excessive latency.

Which solution will meet this requirement?

Show Suggested Answer Hide Answer
Suggested Answer: B

Transit Gateway for Centralized Routing: A transit gateway centralizes the management and routing of multiple Site-to-Site VPN connections. It helps optimize network paths and reduce latency by avoiding the need for direct peering between each VPC and on-premises.

Accelerated Site-to-Site VPN: AWS accelerated Site-to-Site VPN connections use AWS Global Accelerator to reduce latency by leveraging the AWS global network to route traffic more efficiently. This significantly improves the performance of the applications.

Supports Existing IPv4 Configuration: Accelerated VPNs can work with IPv4 addresses, allowing the company to address latency without requiring migration to IPv6, which would introduce additional complexity.

Option C is interesting, but IPv6 won’t solve the latency problem.

I feel like D is a bit off. PrivateLink is great, but not for this scenario.

IPv6? Not sure that would help much here.

I feel like using IPv6 might not directly address the latency issue, but I could be wrong. I need to think more about how that impacts performance.

I practiced a similar question where replacing VPNs with AWS PrivateLink was suggested, but I’m not confident if that’s the best choice here.

I think deploying a transit gateway could be a good option since it simplifies the network architecture, but I’m unsure about the latency improvement.

I remember studying about AWS Global Accelerator, but I’m not sure if it really helps with VPN connections specifically.
