- A
Transit Gateway flow logs
Why wrong: Transit Gateway flow logs provide monitoring and logging of traffic but do not enforce routing. They cannot ensure traffic is inspected; they only help verify inspection after it is configured.
- B
Transit Gateway multicast
Why wrong: Transit Gateway multicast handles multicast traffic and is not relevant for ensuring all unicast inter-VPC traffic goes through inspection.
- C
Transit Gateway route tables
Transit Gateway route tables allow you to control routing between attachments. By configuring route tables to send traffic to the inspection VPC's attachment, you enforce that all inter-VPC traffic is inspected.
- D
Transit Gateway peering
Why wrong: Transit Gateway peering connects two transit gateways, typically for cross-account or cross-region connectivity, and does not enforce inspection within a single transit gateway.
Using Transit Gateway Flow Logs to Verify Inter-VPC Traffic Inspection
This ANS-C01 practice question tests your understanding of network management and operations. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. A key principle to apply: transit Gateway Route Tables. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses a centralized inspection VPC for traffic inspection. All VPCs route traffic to the inspection VPC via Transit Gateway. The security team wants to ensure that all traffic between VPCs is inspected by a network virtual appliance in the inspection VPC. Which Transit Gateway feature should be configured?
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
Transit Gateway route tables
To ensure that all traffic between VPCs is inspected by the network virtual appliance in the inspection VPC, you must control the routing. Transit Gateway route tables (Option C) allow you to define which traffic is sent to the inspection VPC by associating attachments with specific route tables and adding static routes or propagating routes. This ensures that inter-VPC traffic is forced through the inspection appliance before reaching its destination. Transit Gateway flow logs (Option A) only provide visibility into traffic but do not enforce inspection; they are a monitoring tool, not a routing mechanism. Therefore, Option C is correct, while Options A, B, and D are incorrect.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Candidates often confuse monitoring with enforcement. Flow logs show what traffic passes through, but they do not force traffic to go where you want. To actually enforce inspection, you need proper routing configuration via route tables.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
