Exam AWS Certified Advanced Networking - Specialty ANS-C01 topic 1 question 66 discussion

Exam question from Amazon's AWS Certified Advanced Networking - Specialty ANS-C01
Question #: 66
Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

A company is using an AWS Site-to-Site VPN connection from the company's on-premises data center to a virtual private gateway in the AWS Cloud Because of congestion, the company is experiencing availability and performance issues as traffic travels across the internet before the traffic reaches AWS. A network engineer must reduce these issues for the connection as quickly as possible with minimum administration effort.
Which solution will meet these requirements?

  • A. Edit the existing Site-to-Site VPN connection by enabling acceleration. Stop and start the VPN service on the customer gateway for the new setting to take effect.
  • B. Configure a transit gateway in the same AWS Region as the existing virtual private gateway. Create a new accelerated Site-to-Site VPN connection. Connect the new connection to the transit gateway by using a VPN attachment. Update the customer gateway device to use the new Site to Site VPN connection. Delete the existing Site-to-Site VPN connection
  • C. Create a new accelerated Site-to-Site VPN connection. Connect the new Site-to-Site VPN connection to the existing virtual private gateway. Update the customer gateway device to use the new Site-to-Site VPN connection. Delete the existing Site-to-Site VPN connection.
  • D. Create a new AWS Direct Connect connection with a private VIF between the on-premises data center and the AWS Cloud. Update the customer gateway device to use the new Direct Connect connection. Delete the existing Site-to-Site VPN connection.

B - correct Acceleration is only supported for Site-to-Site VPN connections that are attached to a transit gateway. Virtual private gateways do not support accelerated VPN connections. https://docs.aws.amazon.com/vpn/latest/s2svpn/accelerated-vpn.html

The correct answer is C. Option B is incorrect because it involves unnecessary steps of creating a transit gateway and using a VPN attachment. The question does not mention any requirement for a transit gateway.

Correct answer is B. The transit gateway is required because acceleration is only allowed on S2S VPN through a Transit Gateway.

Selected Answer: B
B is the correct answer. Accelerated site-to-site VPN is the usage of AWS Global Accelerator as an entry point to route traffic from your on-prem to AWS edge location that is closest to customer GW to avoid any congestions on the Internet. It only works with TGW.

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.

Acceleration is only supported for Site-to-Site VPN connections that are attached to a transit gateway. Virtual private gateways do not support accelerated VPN connections. An Accelerated Site-to-Site VPN connection cannot be used with an AWS Direct Connect public virtual interface.
