ANS-C01 Network Security, Compliance and Governance Practice Question
A company is designing a network security architecture for a multi-account AWS environment. They need to centrally inspect and filter traffic between VPCs using a third-party firewall appliance. Which AWS service should they use to route traffic through the inspection VPC?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Transit Gateway
AWS Transit Gateway allows centralized routing and can forward traffic to a central inspection VPC for firewall inspection. Option A is wrong because VPC Peering does not support transitive routing and is not centralized. Option B is wrong because AWS Direct Connect is for on-premises connectivity, not inter-VPC routing. Option D is wrong because VPC Endpoints are for private access to AWS services, not for routing inter-VPC traffic.
