ANS-C01 Network Security, Compliance and Governance Practice Question
This ANS-C01 practice question tests your understanding of network security, compliance and governance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 is designing a hub-and-spoke network in AWS. The security team requires that all traffic between VPCs in different spokes must be inspected by a third-party firewall deployed in the hub VPC. Which architecture meets this requirement with minimal complexity?
Create VPC peering connections between each spoke VPC and configure security groups to enforce inspection.
Why wrong: VPC peering does not provide centralized inspection.
B
Use AWS PrivateLink to connect all spoke VPCs to a central service in the hub.
Why wrong: PrivateLink is for accessing services, not routing traffic between VPCs.
C
Use a Transit Gateway with separate route tables for each spoke VPC, and configure the spoke route tables to route all inter-spoke traffic through the hub VPC firewall.
This forces traffic through the inspection firewall.
D
Set up AWS Direct Connect between all VPCs and route through a central firewall.
Why wrong: Direct Connect is not designed for inter-VPC routing.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a Transit Gateway with separate route tables for each spoke VPC, and configure the spoke route tables to route all inter-spoke traffic through the hub VPC firewall.
Option A is correct because Transit Gateway with route tables in each spoke pointing default route to the hub VPC forces traffic through the firewall. Option B is wrong because VPC peering does not centralize inspection. Option C is wrong because AWS PrivateLink is for service access, not inter-VPC routing. Option D is wrong because Direct Connect is for on-premises connectivity.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
