Answer: Set up an AWS Direct Connect connection between the on-premises data center and AWS, provision a transit VIF, and link it to a Direct Connect gateway. Subsequently, connect the Direct Connect gateway to all other VPCs using a transit gateway in each respective Region.
The correct answer is B. Establishing an AWS Direct Connect connection between the on-premises data center and AWS, provisioning a transit Virtual Interface (VIF), and connecting it to a Direct Connect gateway is the appropriate solution. This approach meets all the requirements for minimizing network outbound traffic costs, increasing bandwidth throughput, and ensuring a consistent network experience across different AWS Regions. Utilizing a transit gateway in each Region to connect the Direct Connect gateway to all VPCs allows for efficient transitive routing capabilities between VPC networks.

A company requires a robust connection from its on-premises data center to AWS, facilitating the connection of all its VPCs across various AWS Regions with transitive routing capabilities. The solution must minimize network outbound traffic costs, enhance bandwidth throughput, and ensure a consistent network experience for end users. Which AWS service configuration meets these stringent requirements?
A
Establish an AWS Site-to-Site VPN connection between the on-premises data center and a central VPC, followed by creating VPC peering connections originating from the central VPC to all other VPCs.
B
Set up an AWS Direct Connect connection between the on-premises data center and AWS, provision a transit VIF, and link it to a Direct Connect gateway. Subsequently, connect the Direct Connect gateway to all other VPCs using a transit gateway in each respective Region.
C
Deploy an AWS Site-to-Site VPN connection between the on-premises data center and a central VPC, then utilize a transit gateway with dynamic routing to connect the transit gateway to all other VPCs.
D
Implement an AWS Direct Connect connection between the on-premises data center and AWS, and concurrently establish an AWS Site-to-Site VPN connection between all VPCs in each Region. Finally, create VPC peering connections from the central VPC to all other VPCs.
