Exam AWS Certified Advanced Networking - Specialty ANS-C01 topic 1 question 78 discussion

Exam question from Amazon's AWS Certified Advanced Networking - Specialty ANS-C01
Question #: 78
Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

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?

  • A. Create 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.
  • B. Modify 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.
  • C. Create 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.
  • D. Create 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.

A is the correct answer. Accelerated site-to-site VPN is available only with TGW VPN attachment, where you can enable it, but you do not manage or even view the accelerators.

Selected Answer: A
Acceleration drops the VPN into the nearest GA so the connection goes over the Atlantic on fast, private AWS links, not congested public ones. Both TGW peering and VPNs use encryption. So you gain nothing (in terms of latency) by using peered TGWs even though a VPN is between 10% and 20% more latency impaired than an unencrypted network. Bandwidth considerations are out of scope.

Modification is not possible. -> B wrong, A right. https://docs.aws.amazon.com/vpn/latest/s2svpn/accelerated-vpn.html You cannot turn on or turn off acceleration for an existing Site-to-Site VPN connection. Instead, you can create a new Site-to-Site VPN connection with acceleration on or off as needed. Then, configure your customer gateway device to use the new Site-to-Site VPN connection and delete the old Site-to-Site VPN connection.

Option C involves creating a new transit gateway in the eu-west-2 (London) Region and peering it with the existing transit gateway. The existing Site-to-Site VPN connection would then be modified to use the new transit gateway as the target gateway. This approach could help reduce latency by providing a more direct route for traffic between the London office and the VPC hosting the business applications. Although unsure whether this is the most cost effective or efficient way, however cost and efficiency factors are not asked in this question.

The company workload is only in us-east-1, and they don't use any other region, hence no point of creating a new TGW in eu-west-2 and peer with TGW in us-east-1, Answer is A
