Answer: Configure transit gateway peering between each company's transit gateway. Configure VPC Flow Logs for all VPCs. Publish the flow logs to Amazon CloudWatch. Use AWS Transit Gateway Network Manager to monitor the transit gateways, their respective connections, and the transit gateway peering link.
The question revolves around optimizing network visibility, throughput, logging, and monitoring between two merging companies with a significant AWS presence. Both companies use AWS Direct Connect with a Direct Connect gateway, have a transit gateway, and multiple AWS Site-to-Site VPN connections. The key to the solution lies in leveraging AWS Transit Gateway Network Manager for comprehensive monitoring and management of the transit gateways and their connections, including the peering link. This approach not only ensures optimal network visibility and throughput but also enhances logging and monitoring capabilities. Option D stands out as it suggests configuring transit gateway peering, which is more efficient for inter-VPC communication than Site-to-Site VPN connections, and using AWS Transit Gateway Network Manager for monitoring, which provides a centralized view of the entire network, including the transit gateway peering link. This solution aligns perfectly with the requirements of optimizing network visibility, throughput, logging, and monitoring.

Two companies with a significant AWS presence, each having multiple VPCs, are merging and need to design connectivity between their AWS networks. Both companies currently use AWS Direct Connect with a Direct Connect gateway, as well as a transit gateway with multiple AWS Site-to-Site VPN connections to on-premises resources. The new solution must ensure optimized network visibility, throughput, logging, and monitoring.
Which solution will meet these requirements?
A
Configure a Site-to-Site VPN connection between each company's transit gateway to establish reachability between the respective networks. Configure VPC Flow Logs for all VPCs. Publish the flow logs to Amazon CloudWatch. Use VPC Reachability Analyzer to monitor connectivity.
B
Configure a Site-to-Site VPN connection between each company's transit gateway to establish reachability between the respective networks. Configure VPC Flow Logs for all VPCs. Publish the flow logs to Amazon CloudWatch. Use AWS Transit Gateway Network Manager to monitor the transit gateways and their respective connections.
C
Configure transit gateway peering between each company's transit gateway. Configure VPC Flow Logs for all VPCs. Publish the flow logs to Amazon CloudWatch. Use VPC Reachability Analyzer to monitor connectivity.
D
Configure transit gateway peering between each company's transit gateway. Configure VPC Flow Logs for all VPCs. Publish the flow logs to Amazon CloudWatch. Use AWS Transit Gateway Network Manager to monitor the transit gateways, their respective connections, and the transit gateway peering link.
