ANS-C01 Network Security, Compliance and Governance Practice Question
A company needs to ensure that all outbound traffic from a VPC goes through a centralized inspection appliance in a different VPC. Which TWO actions must be taken to achieve this?
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
✓
Use AWS Transit Gateway with appropriate route tables to direct traffic to the inspection VPC.
The correct answers are D and E. D: AWS Transit Gateway enables transitive routing between VPCs. By configuring appropriate route tables, traffic from source VPCs can be directed to the inspection VPC for centralized inspection. E: After the inspection appliance processes the traffic, it must be forwarded to its final destination. This requires proper routing in the inspection VPC to send the inspected traffic out to the internet or to another VPC. Option A is incorrect because VPC endpoints only provide private access to AWS services, not general internet traffic routing. Option B is incorrect because AWS Direct Connect Gateway is used for connecting on-premises networks to AWS, not for routing between VPCs. Option C is incorrect because VPC peering does not support transitive routing; it only allows direct communication between two VPCs, not through a third VPC.
