Answer: Deploy one transit gateway and attach all VPCs to it. Update the transit gateway and VPC route tables to allow any VPC to connect to any other VPC., Provision one transit gateway VPN attachment for each data center to build connectivity between the on-premises data centers and AWS VPCs.
To meet the company's requirements for VPC-to-VPC connectivity and secure connections between on-premises data centers and AWS during the migration process, the following steps are recommended: A. Deploy one transit gateway and attach all VPCs to it. This solution allows for scalable and efficient VPC-to-VPC connectivity by updating the transit gateway and VPC route tables. It simplifies the network architecture and reduces operational complexity. D. Provision one transit gateway VPN attachment for each data center. This approach provides secure and reliable connectivity between the on-premises data centers and AWS VPCs through the transit gateway. It leverages the existing transit gateway for both VPC-to-VPC and on-premises-to-VPC connectivity, minimizing long-term operational and human resources costs. These options together offer a comprehensive solution that addresses the need for secure, scalable, and cost-effective connectivity during and after the migration process.

A retail company is transitioning its on-premises application to the AWS Cloud. The company operates two on-premises data centers: one on the east coast of the United States and one on the west coast. Each data center contains four database systems, with the largest database storing 500 GB of data. The data centers are connected via two 10 GbE circuits for data synchronization and each has two separate 1 GbE internet connections. The company intends to establish eight VPCs across the us-east-1 and us-west-2 Regions, with four VPCs in each region.
A network engineer must design a connectivity solution that ensures VPC-to-VPC communication and provides secure connections between the on-premises data centers and AWS during the migration. The solution must accommodate traffic spikes during database synchronization, enable the migration to be completed within a single weekend, and minimize long-term operational and human resource costs.
Which two steps should be combined to meet these requirements?
A
Deploy one transit gateway and attach all VPCs to it. Update the transit gateway and VPC route tables to allow any VPC to connect to any other VPC.
B
Configure VPC peering between all the VPCs. Update the VPC route tables to allow connectivity.
C
Provision two AWS Direct Connect connections from two Direct Connect locations that serve us-east-1 and us-west-2 to provide connectivity between the data centers and AWS.
D
Provision one transit gateway VPN attachment for each data center to build connectivity between the on-premises data centers and AWS VPCs.
E
Provision one AWS Site-to-Site VPN connection for each data center and for each VPC to build connectivity between the on-premises data centers and AWS VPCs.
