Topic 1 Question 100
A network engineer is designing a hybrid networking environment that will connect a company's corporate network to the company's AWS environment. The AWS environment consists of 30 VPCs in 3 AWS Regions.
The network engineer needs to implement a solution to centrally filter traffic by using a firewall that the company's security team has approved. The solution must give all the VPCs the ability to connect to each other. Connectivity between AWS and the corporate network must meet a minimum bandwidth requirement of 2 Gbps.
Which solution will meet these requirements?
Deploy an IPsec VPN connection between the corporate network and a new transit gateway. Connect all VPCs to the transit gateway. Associate the approved firewall with the transit gateway.
Deploy a single 10 Gbps AWS Direct Connect connection between the corporate network and virtual private gateway of each VPC. Connect the virtual private gateways to a Direct Connect gateway. Build an IPsec tunnel to a new transit VPC. Deploy the approved firewall to the transit VPC.
Deploy two 1 Gbps AWS Direct Connect connections in different Direct Connect locations to connect to the corporate network. Build a transit VIF on each connection to a Direct Connect gateway. Associate the Direct Connect gateway with a new transit gateway for each Region. Configure the VIFs to use equal-cost multipath (ECMP) routing. Connect all the VPCs in the three Regions to the transit gateway. Configure the transit gateway route table to route traffic to an inspection VPDeploy the approved firewall to the inspection VPC.
Deploy four 1 Gbps AWS Direct Connect connections in different Direct Connect locations to connect to the corporate network. Build a transit VIF on each connection to a Direct Connect gateway. Associate the Direct Connect gateway with a new transit gateway for each Region. Connect the transit gateways by using a transit gateway peering attachment. Configure the VIFs to use equal-cost multipath (ECMP) routing. Configure transit gateway route tables to route traffic to an inspection VPC. Deploy the approved firewall to the inspection VPC.

This solution meets the requirements because:
• It uses AWS Direct Connect, which provides a dedicated and private connection between the corporate network and AWS, with a minimum bandwidth of 2 Gbps (4 x 1 Gbps).
• It uses a Direct Connect gateway, which allows multiple VPCs in different Regions to share the same Direct Connect connection.
• It uses a transit gateway, which acts as a network hub that connects multiple VPCs and other networks, such as the corporate network and the inspection VPC.
• It uses a transit gateway peering attachment, which enables routing between transit gateways in different Regions.
• It uses ECMP routing, which allows traffic to be distributed across multiple paths for higher throughput and redundancy.
• It uses an inspection VPC, which hosts the approved firewall and filters traffic between the corporate network and the AWS environment.

I think the key is the need for connecting all the VPCs in different regions together and you can only accomplish that with the TGW peering in D.

option C - each region has a DXGW but maximum 3 VPC can connect on single DXGW without TGW. Option : D , has TGW with DXGW can connect multiple VPC with TGW peering.
