Correct answer & explanation
✓
Transit Gateway with route tables
A Transit Gateway with route tables allows central routing and inspection. Option A is wrong because VPC peering does not support centralized inspection easily. Option B is correct because Transit Gateway can route traffic between VPCs and subnets with centralized inspection. Option C is wrong because NAT Gateway is for outbound internet traffic. Option D is wrong because a Network Load Balancer is for load balancing, not routing.
