Selected Answer: B

In fact site to site VPN would be more affordable than deploying a Direct Connect leased line. However, AWS also wants to market their product by stating that there is a need to increase throughput (site to site only can achieve max of 1.25Gbps) and consistent user experience (AWS Direct Connect > Site-to-Site VPN) so B would be a better choice.

Selected Answer: B

B. Cant be D because TGW doesnt support transitive connections, so if users connect to a VPN it invalidate this options. A and C are skippable on the first phrase.
