A company operates a highly available application across multiple VPCs within a single AWS Region and two on-premises data centers. All VPCs need to communicate with each other and with the on-premises data centers to transfer large files, each several gigabytes in size. A network engineer is tasked with designing an AWS Direct Connect solution to connect the on-premises data centers to each VPC.
Which architecture will fulfill the company's requirements while minimizing operational overhead?
A
Configure a virtual private gateway and a private VIF in each VPC in the Region. Configure a Direct Connect gateway. Associate the VIF of every VPC with the Direct Connect gateway. Create a new private VIF that connects the Direct Connect gateway to each on-premises data center. Configure the new private VIF to exchange BGP routes with the on-premises data centers and to have an MTU of 9001. Use VPC peering between each VPC. Configure static routing in each VPC to provide inter-VPC routing.
B
Configure a virtual private gateway and a private VIF in each VPC in the Region. Configure a Direct Connect gateway. Associate the VIF of every VPC with the Direct Connect gateway. Create a new private VIF that connects the Direct Connect gateway to each on-premises data center. Configure the new private VIF to exchange BGP routes with the on-premises data centers and to have an MTU of 8500. Use VPC peering between each VPC. Configure static routing in each VPC to provide inter-VPC routing.
C
Configure a transit gateway in the same Region of each VPAttach each VPC to the transit gateway. Configure a Direct Connect gateway. Associate the Direct Connect gateway with the transit gateway. Associate a new transit VIF with each Direct Connect connection. Configure the new transit VIF to exchange BGP routes and to have an MTU of 9001. Configure route propagation between each VPC and the transit gateway.
D
Configure a transit gateway in the same Region of each VPC. Attach each VPC to the transit gateway. Configure a Direct Connect gateway. Associate the Direct Connect gateway with the transit gateway. Associate a new transit VIF with each Direct Connect connection. Configure the new transit VIF to exchange BGP routes and to have an MTU of 8500. Configure route propagation between each VPC and the transit gateway.
