- A
Deploy a central inspection VPC with AWS Network Firewall and use Transit Gateway to route traffic from all VPCs through it.
Centralized inspection with AWS Network Firewall and Transit Gateway is recommended.
- B
Use AWS Network Firewall in each VPC and aggregate logs centrally.
Why wrong: Higher operational overhead than centralised approach.
- C
Enable VPC flow logs in each account and send them to a central S3 bucket. Use Network Access Analyzer for inspection.
Why wrong: Flow logs are for monitoring, not inspection; Network Access Analyzer is for auditing, not inline.
- D
Create VPC peering connections between all VPCs and deploy a third-party firewall in one VPC.
Why wrong: VPC peering is not transitive, so not all VPCs can route through one.

ANS-C01 Network Implementation Practice Question
This ANS-C01 practice question tests your understanding of network implementation. 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 multi-account AWS environment using AWS Organizations. They need to centralize VPC flow logs and network traffic inspection across all accounts. Which architecture meets these requirements with minimal operational overhead?
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
✓
Deploy a central inspection VPC with AWS Network Firewall and use Transit Gateway to route traffic from all VPCs through it.
Option A is correct because it uses a central inspection VPC with AWS Network Firewall and Transit Gateway to route traffic from all VPCs through a single inspection point. This architecture centralizes both VPC flow logs and traffic inspection with minimal operational overhead, as Transit Gateway simplifies network connectivity and AWS Network Firewall provides managed, scalable inspection without per-account firewall management.
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.
- ✓
Deploy a central inspection VPC with AWS Network Firewall and use Transit Gateway to route traffic from all VPCs through it.
- ✗
Use AWS Network Firewall in each VPC and aggregate logs centrally.
Why it's wrong here
Higher operational overhead than centralised approach.
- ✗
Enable VPC flow logs in each account and send them to a central S3 bucket. Use Network Access Analyzer for inspection.
Why it's wrong here
Flow logs are for monitoring, not inspection; Network Access Analyzer is for auditing, not inline.
- ✗
Create VPC peering connections between all VPCs and deploy a third-party firewall in one VPC.
Why it's wrong here
VPC peering is not transitive, so not all VPCs can route through one.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The ANS-C01 exam often tests the misconception that VPC peering can replace Transit Gateway for centralized inspection, but VPC peering is non-transitive and requires a full mesh, making it unscalable and operationally heavy — Transit Gateway is the correct service for transitive routing with minimal overhead.
Detailed technical explanation
How to think about this question
Transit Gateway uses a hub-and-spoke model with route tables that can selectively propagate routes to direct traffic through the central inspection VPC, while AWS Network Firewall integrates with VPC endpoints to provide stateful inspection, intrusion prevention, and flow logging at scale. Under the hood, AWS Network Firewall uses a Suricata-compatible rule engine, and flow logs are published to Amazon S3 or CloudWatch Logs, enabling centralized log analysis without per-account configuration overhead.
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.
TExam Day Tips
- 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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
