A company operates a VPC with application workloads running on Amazon EC2 instances in a single AWS Region. They aim to extend these workloads to an AWS Local Zone while ensuring bidirectional communication between the workloads in the Local Zone and those in the VPC within the Region. What is the most cost-effective solution to meet these requirements?
A
Create a new VPC in the Local Zone. Attach all the VPCs to a transit gateway. Configure routing for the transit gateway and the VPCs. Deploy instances in the new VPC.
B
Deploy a third-party appliance in a new VPC in the Region. Create a new VPC in the Local Zone. Create VPN connections to the appliance for the VPCs. Deploy instances in the new VPC in the Local Zone.
C
Create a new subnet in the Local Zone. Deploy a third-party appliance in the VPC with interfaces in each subnet. Configure the new subnet to route the Local Zone through the appliance. Deploy instances in the new subnet.
D
Create a new subnet in the Local Zone. Configure the new subnet to use a CIDR block that is within the VPC’s CIDR block. Deploy instances in the new subnet in the Local Zone.
