Answer choices
Why each option matters

Correct answer & explanation
✓
AWS Transit Gateway
Centralized firewall inspection requires a Transit Gateway to route traffic to the firewall VPC, a Gateway Load Balancer to distribute traffic to firewall instances, and appropriate route tables to direct traffic accordingly. VPC peering does not support transitive routing. NAT Gateway is for outbound internet access.
