[All AWS Certified Solutions Architect - Professional Questions]

A company needs to establish a connection from its on-premises data center to AWS. The company needs to connect all of its VPCs that are located in different
AWS Regions with transitive routing capabilities between VPC networks. The company also must reduce network outbound traffic costs, increase bandwidth throughput, and provide a consistent network experience for end users.
Which solution will meet these requirements?

  • A. Create an AWS Site-to-Site VPN connection between the on-premises data center and a new central VPC. Create VPC peering connections that initiate from the central VPC to all other VPCs.
  • B. Create an AWS Direct Connect connection between the on-premises data center and AWS. Provision a transit VIF, and connect it to a Direct Connect gateway. Connect the Direct Connect gateway to all the other VPCs by using a transit gateway in each Region.
  • C. Create an AWS Site-to-Site VPN connection between the on-premises data center and a new central VPC. Use a transit gateway with dynamic routing. Connect the transit gateway to all other VPCs.
  • D. Create an AWS Direct Connect connection between the on-premises data center and AWS. Establish an AWS Site-to-Site VPN connection between all VPCs in each Region. Create VPC peering connections that initiate from the central VPC to all other VPCs.

First answer I came to was B. One requirement of 'boost bandwidth throughput' sort of eliminated 3 of them for me, when comparing VPN to Direct Connect.

Selected Answer: B
There are three stipulations we must meet: - transitive routing - cut network outbound traffic expenditures - boost bandwidth throughput. So first a transit gateway would cover, two other - correct correct So it's B.
