350-701 Practice Question: Connecting multiple VPCs in AWS to a shared…
A company is connecting multiple VPCs in AWS to a shared services VPC using AWS Transit Gateway. They want to inspect east-west traffic between VPCs with a common security policy. Which design best achieves this using Cisco solutions?
⚠ Common exam trap
Cisco often tests the misconception that deploying a firewall in each VPC (Option A) is the only way to inspect east-west traffic, but the trap here is that a centralized inspection model using Transit Gateway is more scalable and policy-consistent, and candidates may overlook the routing configuration required to force traffic through the inspection VPC.

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 a centralized Cisco Firepower instance for inspection
AWS Transit Gateway allows you to route traffic between multiple VPCs through a centralized inspection VPC, where a Cisco Firepower instance can apply a consistent security policy to all east-west traffic. This design avoids deploying separate firewalls in each VPC and ensures that traffic between any two VPCs is inspected by a single, centrally managed policy engine.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy a Cisco Firepower instance in each VPC
Why it's wrong here
Redundant and harder to manage.
- ✗
Use VPC peering with no inspection
Why it's wrong here
No inspection, violates security requirements.
- ✗
Direct Connect to on-premises Cisco ASA
Why it's wrong here
Not for east-west VPC traffic.
- ✓
Use AWS Transit Gateway with a centralized Cisco Firepower instance for inspection
Why this is correct
Centralized inspection simplifies policy management.
