Discuss Amazon ANS-C01 Exam Topic 1 Question 66

A global company runs business applications in the us-east-1 Region inside a VPC. One of the company's regional offices in London uses a virtual private gateway for an AWS Site-to-Site VPN connection tom the VPC. The company has configured a transit gateway and has set up peering between the VPC and other VPCs that various departments in the company use.

Employees at the London office are experiencing latency issues when they connect to the business applications.

What should a network engineer do to reduce this latency?

ACreate a new Site-to-Site VPN connection. Set the transit gateway as the target gateway. Enable acceleration on the new Site-to-Site VPN connection. Update the VPN device in the London office with the new connection details.

BModify the existing Site-to-Site VPN connection by setting the transit gateway as the target gateway. Enable acceleration on the existing Site-to-Site VPN connection.

CCreate a new transit gateway in the eu-west-2 (London) Region. Peer the new transit gateway with the existing transit gateway. Modify the existing Site-to-Site VPN connection by setting the new transit gateway as the target gateway.

DCreate a new AWS Global Accelerator standard accelerator that has an endpoint of the Site-to-Site VPN connection. Update the VPN device in the London office with the new connection details.

Suggested Answer: A

Enabling acceleration for a Site-to-Site VPN connection uses AWS Global Accelerator to route traffic from the on-premises network to an AWS edge location that is closest to the customer gateway device1.AWS Global Accelerator optimizes the network path, using the congestion-free AWS global network to route traffic to the endpoint that provides the best application performance2.Setting the transit gateway as the target gateway enables connectivity between the on-premises network and multiple VPCs that are attached to the transit gateway3.

I would pick B because the tricky part is whether to modify the existing VPN or create a new one.

D is interesting, but I doubt it’s necessary. Stick with A or B for now.

Paz 1 month ago

I agree with C for long-term. New transit gateway could help future-proof the setup.

Eric 2 months ago

C seems too complicated. A or B is more straightforward for quick results.

Lavina 2 months ago

But B is less work. Why create a new connection if we can optimize the current one?

Mary 2 months ago

A has a clear advantage with acceleration. Latency needs to be tackled head-on.

Edna 2 months ago

I feel like B could work too. Just modifying the existing connection seems easier.

Felicitas 2 months ago

I think option A is the best choice. New connection with acceleration sounds solid.

Winifred 2 months ago

D could be overkill for just a latency issue.

Joanna 3 months ago

Surprised that latency is still an issue with a VPN setup like this!

Merissa 3 months ago

C sounds complicated. Why create a new transit gateway?

Jordan 3 months ago

I think B is better since it modifies the existing setup without creating new connections.

Jacob 3 months ago

Option A seems like a solid choice for reducing latency.

Mollie 3 months ago

I vaguely recall something about AWS Global Accelerator, but I’m not sure if it applies here since it’s usually for improving performance for public-facing applications.

Kiera 3 months ago

I’m a bit confused about whether we need a new transit gateway in London or if we can just use the existing one. I feel like I’ve seen both scenarios in my studies.

Richelle 4 months ago

I think modifying the existing VPN connection could be a good option, especially if we can enable acceleration on it. That sounds familiar from practice questions.

Orville 4 months ago

I remember reading about how transit gateways can help with latency, but I'm not sure if creating a new VPN connection is the best approach.
