ANS-C01 Network Security, Compliance and Governance Practice Question
This ANS-C01 practice question tests your understanding of network security, compliance and governance. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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 AWS Transit Gateway to connect multiple VPCs and on-premises networks. The security team wants to ensure that traffic between VPCs is inspected by a centralized firewall appliance in a inspection VPC. Which architecture meets this requirement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Attach all VPCs to a Transit Gateway and create separate route tables for inspection.
Option C is correct because Transit Gateway route tables can direct traffic between VPCs through a central inspection VPC by using blackhole routes or specific associations. Option A is wrong because VPC peering does not support transitive routing and cannot enforce central inspection. Option B is wrong because Direct Connect is for on-premises connectivity and does not provide inter-VPC inspection. Option D is wrong because AWS Network Firewall can be deployed in a single VPC but it is not a requirement to use Transit Gateway with route tables to direct traffic to it.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Create VPC peering connections between all VPCs and route traffic through the inspection VPC.
Why it's wrong here
VPC peering does not support transitive routing; traffic cannot be forced through a central VPC.
✗
Deploy AWS Network Firewall in each VPC and allow traffic to flow directly between VPCs.
Why it's wrong here
This would require separate firewall management per VPC, not centralized inspection.
✓
Attach all VPCs to a Transit Gateway and create separate route tables for inspection.
Why this is correct
Transit Gateway with route tables can direct inter-VPC traffic to a inspection VPC for centralized inspection.

✗
Use AWS Direct Connect Gateway to route traffic between VPCs through the inspection VPC.
Why it's wrong here
Direct Connect is for on-premises connectivity, not inter-VPC traffic.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
