Exam question from Amazon's AWS Certified Advanced Networking - Specialty ANS-C01
Question #: 179
Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

A company hosts infrastructure services in multiple VPCs across multiple accounts in the us-west-2 Region. The VPC CIDR blocks do not overlap. The company wants to connect the VPCs to its data centers by using AWS Site-to-Site VPN tunnels.

The connections must be encrypted in transit. Additionally, the connection from each data center must route to the closest AWS edge location. The connections must be highly available and must accommodate automatic failover.

Which solution will meet these requirements?

  • A. Deploy a transit gateway. Share the transit gateway with each of the other accounts by using AWS Resource Access Manager (AWS RAM). Create VPC attachments to the transit gateway from each service account. Add routes to the on-premises subnet in each of the service VPC route tables by using the attachment as the gateway. Create Site-to-Site VPN tunnel attachments with dynamic routing to the transit gateway. Enable the acceleration feature for the Site-to-Site VPN connection. Configure the VPN tunnels on the on-premises equipment. Configure BGP peering.
  • B. Deploy VPN gateways to each account. Enable the acceleration feature for VPN gateways on each account. Add routes to the on-premises subnet in each of the service VPC route tables. Use the VPNs as the gateway. Configure the VPN tunnels on the on-premises equipment. Configure BGP peering.
  • C. Deploy a transit gateway. Share the transit gateway with each of the other accounts by using AWS Resource Access Manager (AWS RAM). Create VPC attachments to the transit gateway from each service account. Add routes to the on-premises subnet in each of the service VPC route tables by using the attachment as the gateway. Create Site-to-Site VPN tunnel attachments with dynamic routing to the transit gateway. Enable the acceleration feature for the Site-to-Site VPN connection. Configure the VPN tunnels on the on-premises equipment. Configure static routing.
  • D. Deploy VPN gateways to each account. Enable the acceleration feature for VPN gateways on each account. Add routes to the on-premises subnet in each of the service VPC route tables. Use the VPNs as the gateway. Configure the VPN tunnels on the on-premises equipment. Configure static routing.

automatic failover = BGP -> so we exclude static acceleration is not possible in Virtual private gateway -> and this is how we remain with (A)

Looks good, A over C just due to dynamic routing with BGP peering instead of static routing.
