What is the next step the network engineer should take to ensure highly available access from Example Corp's VPC (with CIDR 10.0.0.0/16 and an additional CIDR of 10.1.0.0/24) to AnyCompany's on-premises application, using AWS Direct Connect and AWS Transit Gateway, while restricting access to the approved IP range of 10.1.0.0/24?
A
In each Availability Zone in the VPC, create a subnet that uses part of the allowed IP address range. Create a public NAT gateway in each of the new subnets. Update the route tables that are associated with other subnets to route application traffic to the public NAT gateway in the corresponding Availability Zone. Add a route to the route table that is associated with the subnets of the public NAT gateways to send traffic destined for the application to the transit gateway.
B
In each Availability Zone in the VPC, create a subnet that uses part of the allowed IP address range. Create a private NAT gateway in each of the new subnets. Update the route tables that are associated with other subnets to route application traffic to the private NAT gateway in the corresponding Availability Zone. Add a route to the route table that is associated with the subnets of the private NAT gateways to send traffic destined for the application to the transit gateway.
C
In the VPC, create a subnet that uses the allowed IP address range. Create a private NAT gateway in the new subnet. Update the route tables that are associated with other subnets to route application traffic to the private NAT gateway. Add a route to the route table that is associated with the subnet of the private NAT gateway to send traffic destined for the application to the transit gateway.
D
In the VPC, create a subnet that uses the allowed IP address range. Create a public NAT gateway in the new subnet. Update the route tables that are associated with other subnets to route application traffic to the public NAT gateway. Add a route to the route table that is associated with the subnet of the public NAT gateway to send traffic destined for the application to the transit gateway.
