AWS Certified Advanced Networking – Specialty (ANS-C01) — Question 82

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?

Answer options

• 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.

Correct answer: A

Explanation

Creating a new Site-to-Site VPN connection with the transit gateway set as the target and enabling acceleration helps to optimize the connection, reducing latency for users in London. Modifying the existing VPN (Option B) may not provide the same level of optimization, while creating a new transit gateway (Option C) is unnecessary and complex. The Global Accelerator (Option D) is not suitable for VPN connections as it is designed for different use cases.
